Here is a crawl space that we were able to in and do a full encapsulation on. After we did some repair to the support posts they also get encapsulated, ensuring the space stays safe and clean and airtight.

This wet crawlspace had such high relative humidity that the insulation was falling and molding. In addition to this, some of the posts in the foundation were beginning to show signs of rot. 

Our team came in and removed the water and moisture from the crawlspace, installed our CleanSpace system and ensured that humidity would never be a problem again through the installation of a dehumidifier.

Job Stories From Multnomah County, OR
Finishing a basement in Portland Oregon

Shawn had a wet basement in his otherwise fabulous Portland home. Our team came in and installed a partial Waterguard system. While this took care of the water coming into the basement, it was not a full solution. During one of our proactive service appointments Shawn complained he still had some damp areas in his basement and odor issues. Our service technician recommended finishing the Waterguard system, and installing a Sanidry dehumidifier to reduce the moisture in the basement.  Shawn could  finally finish his basement remodeling and add more living space to his beautiful Portland home. We also gave him information about Total Basement finishing and our line of products designed specifically for basement environments.

The tunnel in Portland OR Raleigh st

This job was unique. This home had a basement with an attached tunnel that led to a tool shed. Upon entering the tunnel you were able to see areas where the water came in through tiny cracks along the wall and top of the tunnel. The basement was more of the same, as well as the garage. Considering the house was in preparation for sale, the owners new the problem had to be addressed.

Our company came in and installed our Waterguard system, Drain mat, and a French drain system to address any water that may seep into the home. We also installed Thermadry Flooring and an Egress Rockwell to add a finished beauty to the system.

The homeowners wrote us this lovely letter to talk about their experience with John's Waterproofing Company:

"We are writing to express how completely satisfied we are with all the John's Waterproofing folks who have guided us through the process of finding a solution to our basement woes. It was only months ago that we could be found washing and drying towels after sopping up water from the basement bedroom and garage floors. Since the new waterproofing system has been completed, we have endured several stretches of rainy days without any problems. We couldn't be happier!

Your staff has been especially helpful in so many ways. Jacob Bilyeu deserves a special thanks for conceiving the system that would capture any water seeping through the walls and floors of our basement bedroom, the tunnel leading down to our garage and the garage itself. I have happily explained to family & friends how the network of Thermal Dry, Water Guard & Drain Mat in the basement bedroom collects water that may seep into the bedroom conveying it to the French drain & Drain mat under the tunnel floor, down to join water that collects in the Water Guard on the perimeter of our garage, and out to the gutter. Your technicians have been most helpful in showing me how to flush the system from two access locations; information I will pass on to the new owner of the house. Of course Egress Rockwell adds beauty to the egress window installed by Lifetime Windows.

We also wish to express great appreciation for the flexibility of scheduling that John's showed which allowed us to arrange for All-American Concrete, Lifetime Windows and our carpenter who did the framing in the basement bedroom to fit us into their busy schedules in order for us to get our house on the market in a timely fashion. Allowing our multiple contractors to have access to a John's Waterproofing representative while doing their part of the project was a critical step in interfacing all efforts. For her efforts and cooperation we must especially thank Marisol for helping to make it all happen!

The men who labored hard to prepare our house and install your technology deserve credit as well. Manuel and his crew did great work and took the time to explain how the system would work once completed.

After searching the internet for methods of trying to achieve a dry basement we settled on John's philosophy of directing water that manages to find its way into a house. We will make an effort to share that information with other homeowners who seek the same solution as we did. A good start will be our positive report to Angie's List. Thanks to you and all of your staff for what appears to have been a very successful job! Let it rain."

This house now has a beautiful basement room, capable of withstanding the elements and an amazing warranty to go with it. What was once a problem area is now a unique and beautiful feature of the home.

Waterproofing on New Construction

The best way to ensure that your home will not have a leaky basement is to waterproof the exterior walls at new construction. This is less intrusive and can be done rather quickly.

Finished walls hide a larger issue in Portland

This home owner knew they had musty smells and guessed they might have some moisture issues. (Aside from the one very obvious window leak. They did not expect what they found behind their drywall. Our crew installed a waterguard drainage system and will also be installing a wall system to ensure water will not get to the finished walls in the future.

Eroding foundation and a lake in Troutdale Oregon

This homeowner complained that they have some occasional water in the winter and in heavy rains and some puddles in the crawlspace. They figured that summer was the best time to get it taken care of. Our inspection revealed that the problem was much larger than anticipated. The concrete foundation was crumbling due to constant moisture under this home. The lines on the ripped visqueen and the drainage pipe under the home, show the depths that water has sat during the rainy times. Our crews came and installed a perimeter drain and sump pump to ensure they never had to worry about water issues again.

Clean Space Encapsulation in Portland Oregon

This crawlspace in Portland Oregon was complete with standing water and falling insulation. She struggled with water coming in from her open vents and the falling insulation was making her home drafty.  Lupe and his team came and installed our patented CleanSpace Encapsulation system in the crawlspace and the Triple Safe sump pump. This ensures that our homeowner never again has to deal with an unhealthy and wet foundation and can enjoy a safer healthier home for years to come. 

Lupe and his team came in and set to work. The work began by removing Sally's falling wet and moldy insulation. They sprayed and removed the existing mold in the foundation wood with Mold X so that she would no longer have mold moving forward with her new system. Before our crew began work they dried out the space providing a clean work environment to not leave any existing problems that may impact the function of the new system. 

Once dry, our team installed our patented CleanSpace Encapsulation system with Terra Block to insulate from the ground up. Our 20 mil thick CleanSpace provides a thick and reliable waterproof vapor barrier. Her system also includes a Triple Safe sump pump with battery backup to keep groundwater at bay. The Sanidry dehumidifier creates an ideal relative humidity year around to ensure healthy breathable air is flowing up into the home year around. Our crew completed the space by insulating all the perimeter walls with spray foam insulation.

WaterGuard System installed in Portland, Oregon

The Homeowner called because they had damp walls and musty odors. This left the homeowners not wanting to be in their basement, robbing them of valuable space. Our inspector, Bob, came in and provided them with a free estimate, recommending our patented WaterGuard system and gave them an option to finish the basement walls. Excited to finally be rid of the problem, our homeowner happily agreed.


Manuel H. and his team quickly set to work to create Alan's new basement space. The team went through and installed out Waterguard perimeter drain system. This system ensures that if water does get in to the basement, it's routed into a specific location and directed to our TripleSafe sump pump as opposed to reaking havoc on our homeowner's basement. After ensuring water would no longer be an issue, the team installed BrightWall panels to create a beautiful and bright finished space.


After completing his basement transformation, Alan was over the moon. He was now able to better utilize his space and felt like his home was healthier for his family and thier visitors.

Dry Crawlspace in Harrisburg, OR Crawlspace

A homeowner in Harrisburg called our office to see what we could do for their wet crawlspace. Our crews went out and first cleared out all debris in the crawlspace. They then installed CleanSpace encapsulation system. CleanSpace will keep any moisture or water vapors from coming into the crawlspace through the floor or walls. This will help lower heating costs for the homeowner and improve the overall health of the crawlspace and rest of the home. Our crews also used Spray foam insulation. Spray foam insulation won't be affected by cold, warm or moist air. It fills in every crack, space, and void, helping reduce energy costs and reduces the risk of mold. A CleanSpace Vent Cover was also installed over the crawlspace vent. This keeps outside air where it should be, outside. This means that no cold, hot or humid air is coming into the crawlspace and causing mold issues. A SuperSump sump pump was put in the crawlspace as well. The SuperSump sump pump not only has a powerful pump that can pump 2,650 gallons of water an hour smoothly and quietly but also has a built-in WaterWatch alarm system that will alert the homeowner to a water problem before any damage is done. There is also now a SaniDry CX dehumidifier in the crawlspace to filter out the air, removing any moisture in the air and ensuring a dry and healthy crawlspace and home. Our teams also installed Smart Jack crawlspace stabilizer to stop settling and raise the floor back to the proper level. This means no more sagging floors or inoperable doors. The homeowner now has a dry crawlspace and a healthier home for years to come.  

Downspout Extension in Bridal Veil, OR

This homeowner was having problems with roof water entering the foundation. Our inspector Ben suggested installing Downspout Extensions. Pedro and his team quickly installed a Lawnscape Outlet which is an underground downspout extension. It connects your downspout to a special LawnScape Outlet sending water away from the foundation while camouflaging the end of the pipe. It can also connect to a sump pump as a discharge line.


Isaiah is now very happy that water is no longer entering the foundation of the house and likes that the LawnScape outlet is completely camouflaged.

Waterguard Perimeter Drain in Corbett, OR Basement

Three homeowners had water migrating through the walls in their basement and called John's Waterproofing out of concern of the negative effects. Our inspector, Travis came up with the perfect solution to help them solve their water issues. He suggested installing Thermal Dry Walls, Bright Wall panels and our patented Waterguard system.


The homeowners quickly agreed to Travis' suggestions and Delfino and his team started waterproofing the basement. They began by installing Thermal Dry walls which improve comfort and energy efficiency by reflecting heat back into the basement space. They then installed Bright Wall panels that turn bare basement walls into bright, beautiful finished walls. Bright Wall panels never need paint or any other maintenance and are designed to work with the Waterguard Perimeter Drain system by directing wall seepage into the drain. The drain then channels the water to the sump pump.


Now that our systems are in place, Ben no longer has water entering into his basement and can enjoy his new, dry and usable space.

Basement to Beautiful Walls in North Plains, WA

In this basement, we installed a waterproofing system, along with basement wall systems. The Waterguard perimeter drain system works to channel water into the Triplesafe sump pump, which will then pump the water out of the basement and into an area far away from the home. The wall systems work to add comfort to the basement, while also acting as a vapor barrier against moisture that can seep in through the porous concrete. They will also channel any water that seeps in higher up on the walls into the Waterguard system as well. This basement is now protected against water, moisture and looks great: the perfect foundation for any basement finishing job.

Tight Crawlspace Access in Portland, OR

This home in Portland, Oregon had a basement and crawlspace combination under their home. They both needed waterproofing. We Waterproofed the basement and installed Thermaldry tile flooring since they had planned to finish the basement. Now that the basement was set, the homeowner was able to finish the basement and put up drywall. After they were finished they called us back out to finish the crawlspace section. This presented itself challenging. The access to the crawlspace was a strange one, they had covered it with drywall. It was very small and high up on the basement wall the homeowners had cut out a small space in the drywall so that the crawlspace could still be accessed. Our crew managed to get in the crawlspace though and get the job done! Once the crew got into the space it was not very large either, they installed Cleanspace and Thermaldry wall in the small area to ensure this space would stay dry and clean behind the drywall. The whole space was now waterproof and will stay that way for years to come!

Waterproofing Combined Space in Portland Oregon

This customer called complaining about water damage in their basement and that they have a hybrid crawlspace area too that collects water that trickles into their basement. Jacob came out to inspect and suggested our full Cleanspace System in the crawlspace as well as drainage and wall systems for the basement. The homeowners were so excited about having a healthy usable space they jumped on the suggestion. Our crews removed all of the wet insulation as well as the torn and dirty vapor that was currently in the crawlspace. Our crews installed a smart drain and perimeter drainage system to prevent catch the water and keep it out of the space. They then finished the space with TerraBlock to provide an extra layer of insulation in the space prior to installing our Cleanspace system and Sanidry Sedona. The crews finished the crawlspace with Spray Foam insulation around the perimeter walls. This will save our customer an average of 30% on their heating and cooling bills over the course of a year. The basement needed a fair amount of work as well. Our crew came in and installed our patented WaterGuard system and finished with walls with BrightWall panels to create a polished finished space.

Wet Basement in Portland, OR

Water was leaking into this basement causing structural damage to the cement above and under it. This customer needed quick help to get back on track with their home improvement plans. So we sent out one of our team members right away to inspect his basement and determine how we could fix the problem. 

AJ went out and inspected the basement and suggested we put in our patented WaterGuard system that goes around the perimeter of the basement that drains water unseen safely away. We would also install our Super sump pump that will remove water out of the basement far away from the house. Along with our FloodRing water tank protection system to ensure a watertight seal that contains flooding and an alarm that alerts you if there is a leak. We finished the walls off with ThermalDry wall that keeps moisture and mold out and helps keep heat in. 

He happily agreed to the plan of action and Timothy and his team went right to work. This costumer no longer has to worry about structural damage happening to his home again due to water.

Basement Wall leaking in Portland

These homeowners called because they had water leaking from the wall in their finished basement. The water was causing damage to the finished wall and carpeting. So they gave us a call to see what we could do before further damage occurred. 

Our team member Vincent went out to inspect the damage and where the water was coming from. He recommended that we install our patented WaterGuard system along with our TripleSafe sump pump. Our WaterGuard system drains into the sump pump unseen. While the TripleSafe sump pumps the water out to a safe area away from the house with its three-level pumps that have a backup battery operated pump. With the damaged wall we would demo the half that was effected and install Everlast Wall Restoration for a nice finish. 

The homeowners were thrilled to have the problem fixed and not have to worry about water damage again. Along with a nice finish with the EverLast Wall Restoration in the finished space.

Basement Flooring in Portland, OR

This customer called seeking help for their semi-finished basement. While working in the basement it was discovered that water had been leaking in for some time. The flooring had water damage and needed to be replaced. 

We sent Eric out to do an inspection of the basement and see what we could do to help. Our team first started with installing a Window Well Duct drainage system, where the water drains down from the Well Duct into your basement drainage system.  We pulled up the damaged flooring that was there and replaced it with ThermalDry Elite Dark Walnut flooring that is water resistant with inorganic materials that won't absorb water; Which means they won't swell or rot. They also can increase the temperature of the floor by ten degrees. We also installed our SaniDry XP that keeps the humidity down and filters the air of mold spores and allergens. 

Our homeowner can now enjoy their beautiful finished space without worrying about water damage or a leaking basement window for years to come.

Leaking Window in Portland, OR

This customer called because they had water coming into their finished basement. They wanted an inspector to come out and find where the water is coming from and to fix it. 

Our inspector Eric went out and found the water had been leaking from the basement window. Water was coming from outside to the window and leaking down the wall to the basement floor. We installed our patented WaterGuard system along the perimeter of the basement floor. To fix the window leaking we installed a window well drain that goes under the window and drains the water to the unseen WaterGuard system. To which drains the water to the Super sump that pumps the water out and away from the house. 

This homeowner can now enjoy his finished basement knowing that water isn't leaking into his basement for years to come.

Basement Puddles in Portland

During the Fall these homeowners started to notice puddles on their basement floor. Every time we would get heavy rains water would leak into the basement and create puddles. They gave us a call for an inspection. 

Our inspector Brandon went out and recommended installing our patented WaterGuard system that goes around the perimeter of the basement. Water then drains unseen into the WaterGuard and runs to the TripleSafe sump pump that has three pumps one being battery operated in case of a power outage. It comes with the patented WaterWatch that sounds off an alarm if the water rises above the operating range of the pumps to alert you before damage occurs. It then pumps out a new discharge line we installed. For a nice finished look, we installed our BrightWall paneling. 

Now, these homeowners will never have to worry when the next heavy rain hits to find puddles. They can enjoy a dry basement for years to come.

CleanSpace in Portland, OR

The homeowner knew he needed an inspection of his crawlspace and gave us a call. When our inspector Bob went down he found puddles of water all over the crawlspace. 

Bob recommended we do a CleanSpace Encapsulation system to completely seal the crawlspace. We installed a TripleSafe sump pump that has three levels of pumps and a battery back pump that runs in case of a power outage. With our patented WaterWatch Alarm that will sound off if water rises above the capacity of the pump to warn you of an issue before damage occurs. Along with our SaniDry Sedona dehumidifier to keep the humidity down and clean air so moisture and mold can't occur. 

This homeowner was so eager for Lupe and his crew to get started. He now has peace of mind that his home is getting clean air and his crawlspace is dry.

Basement Finish in Portland, OR

This customer called because water was leaking into their basement when it would rain. They wanted a forever solution to the water problem and called us for an inspection. We sent out our inspector to take a look and see what we should do. 

Our inspector recommended installing our patented WaterGuard system that goes around the perimeter of the basement unseen and collects water and drains it to a sump pump. We would install our TripleSafe sump pump it has three pump system that protects you from pump failure to much water, and power outage. Along with our patented WaterWatch Alarm that goes off when the water rises above the pump level to prevent damage from occurring. For finished walls, we put ThermalDry Wall up first that reflects heat back into the basement and works with our WaterGuard system. BrightWall paneling went up for a nice basement finished look.

The customer was so happy that they didn't have to worry about water damage occurring to their basement. They can now enjoy a finished space for their home.

Crawlspace Encapsulation Muddy to Clean

This customer called us with a discovered water problem. Water was coming into the crawlspace and was causing moisture and mold spores to grow that it was affecting the walls and air of the house. So we sent out one of our inspectors to see what we could do to fix the problem. 

Our inspector went and found standing water in the crawlspace which had started to ruin the old black plastic vapor barrier and create a muddy mess. We would do a crawlspace clean out and remove the wet sagging fiberglass insulation. We installed our crawlspace encapsulation system with our Cleanspace vapor barrier that is 20 mil thick and tacks on the walls of the crawlspace while sealing the vents. We also installed a smart sump pump that will pump all water out along with our SaniDry Sedona dehumidifier that will keep all moisture, dust mites, and mold spores clear from the air you breathe in your home. We then used our spray foam insulation around the perimeter of the crawlspace efficiently keeping warm air in and a nicely sealed space. 


The homeowner was so relieved to have us encapsulate her crawlspace and they don't have to worry about water or mold again. They now can relax knowing their family will always be breathing clean air in their home.

Everlast well install in Portland

This customer called about water getting into her crawlspace and wanting to look into other options into fixing her crawlspace. We went out and replaced her crawl space access well to give better protection and more durability. Before it was a short access that could rust and had a dirt bottom. The door was not properly sealed shut and left the crawl space vulnerable to water, leaves, and pests. The EverLast system is made with long-lasting materials that will never rust, corrode, support mold growth, or rot. No ugly eyesore in your yard. It is finished with river rock to avoid puddling and mud against your foundation. The customer was pleased with how well it blended with her landscape and knowing it was going to last the life of the house.

Musty Smell in the Basement in Portland

This customer called complaining of water leaking into his partially finished basement and you could notice a musty smell every time you entered the basement. Our crew installed our patented WaterGuard system around the perimeter of the basement that will properly drain the water into our TripleSafe sump pump. Our TripleSafe sump has two pumps that will run to drain the water while the third pump is battery operated and will come on in case of a power outage to help prevent water damage. Due to the leaking water coming from the wall, it had caused water damage to the sheetrock, insulation, and wood. We installed our B to B panels that are moisture resistant and well insulated to keep your basement warm. Along with waterproofing the basement, we installed new rain drains so that the water would drain out away from the house to help ensure that water wouldn't drain down into the foundation of the home. This customer was so relieved to have his storage space back without a worry of water or moisture damage. He also didn't notice the musty smell anymore coming from the basement. 

Crawlspace Encapsulation and p

This homeowner had installed their own sump pump in the crawlspace of their home because they had found water. Over time she had started to notice a musty smell in their home and couldn't find the source of the smell. She finally decided to give us a call and have an inspection done on her crawlspace. Our inspector went out and found standing water in the crawlspace that wasn't draining to the DIY sump pump. While doing the inspection he found mold growth on the foundation wall and floor joists. With continuous exposure to water and moisture in the crawlspace, it takes a toll on the posts and some of the wood posts were starting to rot. Our crew went in and replaced the rotting posts with our SmartJack that is adjustable and made of steel.  We replaced the old sump pump with our TripleSafe sump pump; this pump has three different pumps that will adjust to how many run due to the water level. The third pump is battery operated and will run in a case of a power outage. After the installation, we seal the crawlspace with our CleanSpace vapor barrier that is 20 mils thick and has tear resistant. To further ensure that the crawlspace stays dry and moisture free we put in our SaniDry XP dehumidifier that filters out moisture, mold spores, and dust mites. This homeowner felt so relieved to know that they were breathing clean air in their home and the foundation is protected. 

Natural spring leaking into basement

This customer called with concerns for their basement wall and the water leaking into the basement. Their basement wall sits against their neighbor's hillside and water is coming from a natural spring leaking into the wall creating the perfect space for mold and water damage. Our crew went in and put in a discharge line and our patented WaterGuard system that goes around the basement and drains the water unseen. The  SuperSump pump that has high volume pumping and a built-in alarm that goes off when the water level rises about pump capabilities and is compatible with our WaterGuard system. Due to extreme water damage, we took out the whole wall and installed our ThermalDry wall that helps keep heat in the basement and is made of inorganic material that stops mold and mildew growth. This customer was so relieved to know that water from the natural spring will be properly drained and won't be causing damage to their basement. 

Wet crawlspace in Portland

This customer called because he had seen our trucks frequently in his neighborhood waterproofing his neighbor's homes. To his knowledge, he had no water problems and his crawlspace was dry but wanted us to come to make sure. When the inspection was done they found standing water in the crawlspace in multiple spots. The moisture from the standing water had been absorbed into the fiberglass insulation and was starting to sag and mold was growing on the support beams. Our crew pulled all the insulation out and removed the damaged vapor barrier. Our crew installed our CleanSpace vapor barrier that is 20 mils thick and tear resistant. We installed our TripleSafe sump pump that has three pumps; two pumps will run depending on the amount of water draining into the sump and the third one is a battery operated pump that turns on in case of a power outage. To help keep the humidity level down we installed our SaniDry Sedona dehumidifier that is the perfect size for a crawlspace. It filters out moisture, mold spores, and dust mites from the crawlspace.

Neighbor Water Intrusion; Portland, OR

The homeowner called because their neighbors yard is sloping down into the direction of their home. Which started to lead the water straight into their crawlspace causing water damage. They were looking for some kind of drainage system to help filter all the water back out. So we cleaned out all the damaged products and installed the TripleSafe sump system, which is one of our most reliable pumps. It is meant to withstand flooding and any power failures.

Walkway Restored; Portland, OR

Brendan had just moved into a 96 year old home 3 months prior. And he was soon to learn that there was water leaking into the basement under their kitchen. And the source was unknown. He found Johns Waterproofing Company online after doing some research. 

Daniel came to investigate and reassured them that it was nothing more then a downspout that needed to be fixed. And that there was only minor damage done to their basement. Fernando made sure to clean out the basement, and fix any damages that were caused by the water intrusion. His crew and him dug out a trench to install LawnScape well, which connects to the downspout and discharges the rain water from the gutters away from the yard. Stopping any sort of flooding or swamp-like buildups. 

Giving the customer a pathway that is usable once again, and curb appeal. Brendan hasn't had any problems since the installment and is happy with the outcome of a job well done. 

Crawlspace from wet to dry in Portland, OR

This customer had called us because he had been doing research on air quality and just how much air comes thru our homes from the crawlspace. Up to 50% of the air we breathe in our homes comes from the crawlspace, so having a dry healthy crawlspace is a must. Our inspector went out and looked at the crawlspace, it had sagging insulation from it collecting moisture over time. Due to the high humidity and moisture mold was also growing on the posts and floor joists.  He suggested we do a crawlspace encapsulation with a drainage system.

Our crew went out and removed all the debris, old vapor barrier, and sagging fiberglass insulation. After we have the crawlspace cleaned out we did a mold treatment with a product we use called Mold X. It not only removes the mold but removes the mold stains from the wood. After we clean the crawlspace out we seal the vents shut with our vent covers and installed a drainage system with a smart drain sump pump. We lined the crawlspace with our CleanSpace vapor barrier that is 20 mil thick and is rip resistant. Our crew installed our SaniDry Sedona that is a dehumidifier which filters out air impurities and humidity. You can't hear it run and it makes sure to keep the crawlspace dry. We finished the encapsulation with our spray foam insulation that goes along the foundation of the crawlspace.

The homeowner was so happy to have the mold treated and know his crawlspace will be dry for years to come. Over the year the homeowner will also notice warmer floors and a decrease in his heating and cooling bill. After encapsulation, your home's air won't leak out of cracks and open vents. 

Basement Water Intrusion; Portland, OR

Customer called due to her basement walls starting to leak. The problem wasn't extreme, so it was perfect timing for her to find our ad in the Oregon Home Magazine

Manuel H and his crew started out the job by digging out the trench that the discharge line and WaterGuard would be placed into. ALong with installing the WaterGuard, they had the SuperSump pump installed to cycle the water out of the basement. 

This made it so that when and if the water continues to leak, it would travel down the wall straight into the WaterGuard. Which is then sent down to the SuperSump pump, to be filtered and sent out the discharge line. 

The customer was relieved that it was done in a timely manner. Also knowing that her basement would be dry and clean. 

Plumbing Protection; Portland, OR

John called for water problems in the basement. Which seems to be worse during the fall due to excessive rain. The water seems to diminish during the winter, but freezes while under there. 

Manuel H and his crew went out and started the procedure. Digging the trenches along the concrete walls. They installed the WaterGuard with the flanges against the wall to allow the water to drain directly into it. The water will then travel to the SmartSump pump and go down the Discharge pipeline and out of the home. 

There was a plumbing problem in one wall, which caused the drywall to crumble. So the crew had to start tearing the damaged wall down. After they did that they installed ThermalDry inside of the wall for a thermal break to help any built up condensation. So that moisture buildup would no longer be an issue. Leaving the customer with the reassurance that there would not be any mold issues in the future. 

Four Crawl Space Encapsulation; Portland, OR

The customer called with concerns of her home being on a hillside. And knowing that she has four separate crawl spaces to look after. She was worried that the water is running down the hillside straight into one, or more of her crawlspaces. 

Our crew went out and first cleaned out the crawl spaces. They then started laying down the TerraBlock so that when moisture starts to buildup in the soil, it stays in the soil. Once all of the TerraBlock is laid down, they then installed the 20 mil CleanSpace. When pairing the two together, the water is completely unable to penetrate and cause any form of damage. 

In two of the crawl spaces, they had the Smart Drain installed to alert of any plumbing problems. They also had to isolate all of the piers so that the foundation would not start to shift or cave in. 

And to try and regulate the humidity in the crawl spaces they recommended two SaniDry Sedona dehumidifiers. Which will also assist with temperature regulations.

The customer was impressed that we were able to encapsulate all four spaces with ease. Leaving the space dry and free of any musty smells. 

Foundation Cracks; Portland, OR

Customer called for a crack they found in one of their foundation walls, which was letting water into their basement. We had a simple quick fix, which was Xypex. Its a sealant you paint on cracks and it will temporarily seal them. 

Jake explained to them that their best option would be to go with WaterGuard along the parameter of the basement, and a Paraseal which is a longer lasting sealant. 

About two weeks later we came out again and found that the customer had indeed wanted the lifelong solution. Tyler and his crew installed the WaterGaurd and left the customer with the reassurance that it would keep their basement dry and clean. 

Crawl Space Sealing and Basement Touch Up; Portland, OR

The customer called to have their crawl space sealed, after having a radon mitigation kit installed. So to help complete the fixation of the air quality of the crawl space and basement, they called us looking to seal it all up. 

Francisco and his crew did a full encapsulation of the crawl space and did a complete basement finishing to tie both open areas together. 

For the crawl space, they installed a CleanSpace Drain Matt, that lies underneath all of the other products, to give any water that is building up a space to run in the soil without causing damage to the foundation. On top of that, they then laid down the TerraBlock to keep the water from intruding on the crawl space. To seal it, they used CleanSpace to complete the full encapsulation of the crawl space. 

The basement was a simple and quick fix after the crawl space was finished. They dug out a trench for WaterGuard to take any water and filter it down to the TripleSafe sump pump that was installed. Which will then discharge it out of their home, and off their property. 

Leaving the homeowner happy knowing that the air quality will only be better from here on out. And that any water troubles that may arise will be taken care of in a timely manner. 

Self Installed Sump Pump to Water Guard; Gresham, OR

The customer us when his sump pump started to flood his basement due to sediment buildup. The discharge line they had installed, cracked leaving them with a bigger mess than they ever imagined. 

We came and dried out the basement. Taking out the old sump pump and discharge line. So that we could install our system without any hiccups. Francisco and his crew dug a trench line along the parameter of the basement for the WaterGuard

To replace the old sump pump they installed the SuperSump pump. With a 1 1/2 inch discharge line. Ensuring that when they laid the concrete down no water would intrude the space again. Or cause any more damage, leaving the customer overjoyed with knowing they have storage space once again. 

Groundwater Intrusion; Portland, OR

The customer had groundwater leaking into the basement through cracks in the concrete walls. They were concerned as to what would happen to the living space they created in the basement. 

So our plan was to install a non-intrusive waterproofing system for this family. Which their best option was the WaterGuard system, that lies in a trench along the perimeter walls. With concrete over the top to create a tight seal. 

Which also leads to a SuperSump Plus pump to collect and discharge any collected water straight out of their basement without being seen. 

To finish the basement off, they also had BrightWall Paneling installed on the perimeter walls. WIth a quarter inch gap to give clearance for the water to collect behind the panels, into the WaterGuard without further damage. 

Leaving the family with a beautifully finished basement, and no more musty smells to carry up into the rest of the home. 

Yard Drainage System; Portland, OR

The customer called due to having major seepage issues from multiple points in their basement. A large amount of water came from the window, so they weren't sure if they needed a window replacement, or if it was caused by something else. Tyler and his crew went out and showed them that their rain catching basin was full and they cleaned it out for them. Along with a new downspout extension so that the water would be averted from the windows. Ensuring that the water stays dry and clean.

Crawl Space Entrance Fix-Up; Portland, OR

The customer called for a simple entrance replacement on their crawl space. The other one was the original from when the home was built. They had been using plywood to cover the doorway to keep animals out, but it wasn't keeping the water from building up. Which was concerning them, as they didn't want mold growth to occur. We had the EverLast Access Well and EverLast Door installed. It has foam walls that create a tight air seal, not allowing water access into the crawl space. Giving the customers relief that there wouldn't have any water intrusion or mold growth in the future. 

Finishing and Waterproofing of a Basement; Portland, OR

Dave and his wife were having problems with water seeping from the walls. We recommended getting the full Basement Waterproofing System so that there wouldn't be any more problems in the future.

They weren't sure if they wanted it at that moment, however, after very heavy rainfall in January they decided it was time to start the project. 

Ramon and his crew went and took down the bottom half of each wall to install the ThermalDrywall so the rooms were well insulated. But if the water were to buildup, it would filter down into the WaterGuard. To then be carried down to the SuperSump pump. Discharging the water out of the basement discretely behind the Everlast panels. Also placed meticulously over the new installed ThermalDrywall so that the rooms have a beautiful finished look. 

Sketchy Daylight Basement to Clean Space; Portland, OR

The couple had called after buying a new home that had some not so pleasant secrets. Downstairs was a daylight basement, with a small crawl space attached to one side of the room. But with closer inspection, they found that the vapor barrier that was laid in the crawl space was in shambles. And the moisture from underneath had started to create a very musty smell. Causing the family some concern on if the home would be healthy enough or them. 

They gave us a call, and our salesman reassured them that everything would be fine. As the water had not started to damage anything yet. There was also no sign of mold growth. However, there was one spot that the post was starting to sink into the soil. So he recommended they get a SmartJack to replace the old post. Which will hold up the beams without sinking, due to the crushed stones that we put under it. Giving a sturdy foundation to be on, also allows it to prevent any bowing in the floorboards of the home. 

Our foreman Delfino and his crew had the task of installing the SmartJack, along with the CleanSpace to eliminate excessive water buildup in the home. With the CleanSpace ensuring that the water cant comes up through the soil, they also installed a SmartDrain at the lowest point of the area. To give any water that does make its way in, an exit. The last product they brought to the home was a SaniDry XP, which regulates temperatures and any moisture in the air. 

Giving the family the sense of safety knowing that their home is not going to have low air quality and that the integrity of the house is restored. 

SuperSump Pump; Portland, OR

Cindy had some concerns with her crawl space. The last time she had been down there, there was standing water and insulation falling from the beams. Raising a red flag that her health was at risk, along with concerns of water damage. 

Our salesman went down and did find quite a bit of water. But it was not in dire need for an extreme makeover. But to fix the standing water ground they had the SuperSump Pump installed to expel the water from the crawl space. And laid a new 6 mil Vapor Barrier down to prevent water from coming up from the soil into the crawl space. 

They also made sure to clean up all the built-up debris from the falling insulation, leaving it clean and healthy for years to come. Leaving the customer satisfied with a job well done in a timely manner.

Basement Finishing in Portland, OR

This family had been wanting to use their basement as a second living space, to have a bigger family room and extra storage space. Unfortunately, water had been leaking in from behind the stairs causing moisture problems and a very musty smell. The homeowner had tried every home remedy they could think of and nothing was working for the smell nor the water issue. One morning they heard our ad on the radio and decided to call for a free inspection. 

Our inspector went out and inspected the whole basement to come up with the perfect plan for the homeowners to utilize their basement. Our crews first started by installing our patented WaterGuard system that goes along the basement wall and will properly drain the water down to a sump pump. Our crew installed our SuperSump pump that allows high-volume pumping and has a built-in alarm that will ring in case the water level raises to high. The pump is also airtight and child safe which was important to this family. After the crew had the proper drainage system installed we also put in our SaniDry dehumidifier to help eliminate the moisture in the air and all other air impurities. Since the family wanted to use their basement as a second family room they decided to have us install our basement finishing products. We demoed the walls and installed our B to B panels that work alongside our WaterGuard system. They are moisture resistant and work as a vapor barrier to the basement walls. 

The homeowners were so pleased with their new space and how different their basement looked. They now had the second family room they had been wanting for a long time and could now use the basement for storage. 

Effects of Moisture in the Crawlspace Portland, OR

This customer was having moisture problems in her crawlspace but wasn't sure of the extent it was. She saw an ad of ours in the paper and decided to give us a call. When our inspector went out he found that there was actually quite a bit of moisture in her crawlspace. Since the crawlspace had been exposed for long periods of time to the moisture her posts that hold her floor up where also dry rotting. It was important to get the posts fixed due to sagging floors and sooner or later the post would rot away. 

Our crew went out and cleaned out all the debris from the crawlspace including the old ripped up vapor barrier that had once been laid. We started with installing our SmartJacks, they are a steel post that is made to not ever rot away. It is also adjustable so as the ground settles they can be adjusted to stop floors from sagging. Due to the water getting in the crawlspace our crew installed a drainage pipe that drains to our Super Sump. It is a sump pump designed for the crawlspace that quietly pumps the water out and away from the home. This homeowner opted to just replace her black plastic vapor barrier over encapsulation. We installed the 6 mils black plastic in the crawlspace. 

The homeowner noticed immediately how less uneven her floors felt and that the creaking was minimal. She was glad that she called because she was unaware just how much moisture was down there and the effects of leaving it. She now knows that the sump pump is handling the water issues and that she won't have dry rot anymore. 

First Step to Finishing in Portland, OR

This homeowner knew that in the next two years he wanted to finish his basement to be able to use it for entertaining. So the first step was to waterproof the basement. Our inspector found that there were several points where water was getting into the basement. The basement also had a very strong musty smell from the dampness in the basement. 


Our crew went to work installing our patented WaterGuard drainage system. It designed to keep basements dry while being unseen. Our crew cuts about six inches away from the wall of cement out to lay the drainage and then repaves over it. The WaterGuard drains down to a sump pump. Since so much water was getting into this basement our inspector suggested installing our TripleSafe sump pump. The TripleSafe is a three pump sump that runs the pumps automatically to the level of water draining. It comes with the third pump running on a battery operated the pump in case of a power outage to save the basement from water damage. The pump then pumps the water out the discharge line to take the water out and away from the house so it doesn't continue to come in. In addition, the homeowner had us install our ThermalDry wall that is insulation for basement concrete walls. It works with the WaterGuard system and drains all water down to the drain. It also reflects heat back keeping the basement nice and warm to be comfortable to be in. 

The homeowner was so happy to be able to start moving forward with his plans in the basement. Getting the first step done of waterproofing is so important to finishing a basement. The last thing he wanted was a flooded finished basement. He also has noticed a decrease in the heating bill since the basement was not leaking the heat out constantly. 

Soggy Cleanspace in Southeast Portland

 After reading our article in the newspaper about standing water, Jane knew that she needed to call and have her crawlspace taken care of. One of our inspectors properly came to her home to provide her free inspection. Jane had standing water, falling insulation, and rotting posts. Our inspector Marcus was able to give her a unique solution which included encapsulating her crawlspace with our patented CleanSpace, installing drainage, and then finishing the space with spray foam insulation.

High humidity leads to wood rot

This crawlspace in Gresham was full of water and had an exceptionally high relative humidity. Due to the nearly 80% relative humidity in the crawlspace, the insulation in the crawlspace was falling and molding. Many of the beams were beginning to show wood rot which if not cared for could threaten the structural integrity of the home. 

Our team removed the water in the crawlspace and installed a drainage system to ensure that they will not have water issues again moving forward. Our Triple Safe Sump Pump will ensure that water will no longer be an issue for the homeowner, and was required prior to the installation of the CleanSpace Encapsulation System. 

The system was completed with a dehumidifier installation to ensure that the humidity level in the crawlspace stays at a healthy range to provide quality air to homeowners above.

Crawlspace Water Issues - Shedd, OR

The homeowner had a few rooms in their basement that had been waterproofed and finished by another company a few years back. But their home also had a small crawlspace that was entered via a small doorway from one of the basement rooms. While the basement section had been sealed off from water issues, the crawlspace had not been addressed. The homeowners learned that this was a mistake when they noticed water seeping through the crawlspace entrance door and dripping into their finished basement. Upon opening the door, they saw flooding, and sagging insulation. 

Our crew came out and removed the debris from the crawlspace and got to work! They added in a Condensation Pump and a SaniDry Sedona dehumidifier. These would work together to keep the water and humidity out of the crawlspace. We then added in a 6 Mil Vapor Barrier and Spray Foam around the rim Joists to guarantee water wouldn't be making its way in. To top it off we added new vent covers and an EverLast door so things could be truly sealed off from water damage. 

Basement Cracks in Fairview, OR

This basement has been used as a workshop since the homeowners had moved it. It has one door to the exterior and plenty of room to work in. As the years progressed they began noticing some cracks in their homes foundation, mainly where the concrete floor connected to the walls. While it started having a minor water leak, the water intrusion was getting worse. When the rainy season hit, they needed to move equipment around to keep their shop tools from getting water damage. This was becoming more of a hassle, and it was time to find a solution, so they called John's Waterproofing. 

To solve this water issue, we began by digging a trench around the interior of the basement walls, and we inserted a TrenchDrain by the doorway, and a perforated pipe around the rest of the area. These worked together to bring the water to the new TripleSafe Sump Pump which pushed all the water out and away from the home via a discharge line to a LawnScape outlet a safe distance away from the home. We then covered the new pipes with new concrete and installed a SaniDry dehumidifier to keep the basements vapor levels at an appropriate level as well. This home no longer has water issues, allowing the homeowners access to their full basement workshop year round. 

Above Ground Downspout Causing Water Issues - Bridal Veil, OR

The homeowners had a downspout installed, but to get the water diverted a safe distance away from the homes foundation involved a long pipe to extend away from the home. While they had been okay with this at install, they had issues with it getting damaged since it stuck out so far. They were ready for this downspout to get put in the ground. 

Our crew came out and dug a trench from the downspout near the foundation and installed a pipe to extend out and away from the home. This pipe was then covered again with dirt and grass so it would no longer be an issue. The pipe ended with a new LawnScape outlet which kept the water a safe distance away. 

Prepping a Basement to be Finished in Gresham, OR

The homeowners wanted to get their basement finished, while they wanted to do the finishing work themselves, they knew that it should be waterproofed by a professional so their handiwork would be protected. To get this handled properly they called on John's Waterproofing. 

To prep the space we began by installing our WaterGuard Drainage system. This is installed in a trench around the interior perimeter and collects the water under the foundation of the home. To keep the moisture content from the foundation walls from damaging the space we installed our ThermalDry Wall system, a foil-faced dimpled material that protects against water and also helps maintain the temperature of the basement to save on energy costs. This wall system works well under finished systems and also gives a clean unfinished look. To pump the water from the drainage system we installed a TripleSafe sump pump that diverts all water a safe distance from the home. The basement is now ready for the homeowners to finish. 

We do offer our Total Basement Finishing system for those who can't take on a finishing project themselves. 

Finished Basement has Water Mold on Drywall - Fairview, OR -

This daylight basement is built into the hillside, with only one corner being below the ground level. While the space had been fully finished, the homeowners had not considered water to be a major issue since only a small portion of the area would have dirt on the exterior. However, this side of the basement began to harbor mold and the drywall was squishy around the baseboards. To find a solution, John's Waterproofing was called in to help.

Our crews came out and began by removing the drywall where mold and water were evident. We then pulled up the carpeting along the side that needed attention. The homeowners wanted to save the carpeting, so we dried it out to be used again. A trench was dug along the affected walls and a WaterGaurd drainage system was installed to direct groundwater to a new SuperSump Plus sump pump. From here water was diverted out and away from the home to a LawnScape outlet. We then installed a ThermalDry wall system to waterproof and insulate the affected walls. The homeowners opted to do drywall over this section, and so they had to use a general contractor for this and they also re-installed the carpeting for homeowners. 

This space is now dry and healthy! 

Water Entering Basement along Base of the walls in Troutdale, OR

This homes basement was wet to the touch along the base of the foundation walls, with pooling water evident near the basements exterior entryway. The homeowners were ready for a solution so they didn't need to worry about water damaging the items they kept in this space. 

Our crew began by digging a trench along the interior parameter of the space. In front of the exterior doorway we installed a TrenchDrain to collect water, and than installed our WaterGaurd drainage system around the remainder of the basement. These would collect groundwater and push it along to a newly installed TripleSafe sump pump. From here water is diverted out and away from the home to a new LawnScape outlet. 

Bringing A Crawlspace up to Code in Corbett, OR

As a homeowner gets ready to sell their home, they need to ensure that the home is up to code, and over the years a home can begin to settle. This home settled over the years, leaving their crawlspace with an inadequate amount of room for someone. To bring it back up to code before going on the market, the homeowners called in Johns Waterproofing. 

Our crew did a dig out, removing in total, twenty cubic yards of dirt to have this crawlspace compliant with its local codes. We then installed a 6 Mil vapor barrier to protect against water issues. This home will now be ready to go onto the market. 

Leaky Basement/Yard Drainage - Klickitat, OR

The homeowner was ready to remodel their basement for more living space but didn't want to risk water damage after the expense of the remodel and their contractor encouraged them to call John's Waterproofing for advice. A specialist explained to the homeowner that it was not uncommon for a basement to be dry for years and suddenly flood due to torrential rain or new construction in the area or even insects or animals burrowing and creating waterways. He explained how John's Waterproofing could give them a lifetime warranty on the patented WaterGuard System in that, so long as the pump was operating, the WaterGuard would gather the water and direct it to the pumps.  


The crew got to work right away, breaking out 6" of concrete around the perimeter to install the WaterGuard. It was placed on top of the footing in a bed of gravel and inspection ports were strategically placed and terminated at the SuperSump location. WellDucts were installed at the below grade windows and the ThermalDry wall system was fastened to walls and both were inserted into the flange at the back of the WaterGuard to ensure any wall seepage or window well overflow was directed into the new drainage system. ThermalDry also aids in the insulation of the basement. Over the ThermalDry wall, BrightWall was installed to give the basement light, a bright and clean look. Homeowners also invested in a SaniDry dehumidifier to keep the air clean and dry.


Now this homeowner could invest in his basement remodel with confidence that it will stay dry and healthy.
