We are experts in all things basement and crawlspace. Given this fact, we are not always completing standard waterproofing. Sometimes it is details such as this ThermalDry flooring that make the space more beautiful while providing necessary function. This flooring is raised from the concrete providing a 1-inch thermal barrier that will keep the basement warmer and prevent ground moisture from reaching your space.

It is amazing what a clean space can do for your family's health and the ability to fully take advantage of a space. This homeowner used our thicker CleanSpace vapor barrier for the area he plans to use for home storage, and then the thinner 6 mil plastic in the areas without foot traffic. This will give them great moisture protection as well as large usable space.

Basement Finishing & Remodeling in Sherwood, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include:
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Sherwood contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Job Stories From Sherwood, OR
Encapsulate it, in Sherwood, OR

Jim & Shirley had previously owned a home in Colorado that had been encapsulated due to the high water tables where they lived, so when they relocated to Oregon they already knew that they wanted their home protected here as well. It was a no brainer when they saw Aimee at a Home & Garden Show in Portland, Oregon. They found out that John's Waterproofing has been in the waterproofing business since 1974 and that we are accredited with the American Lung Association. There's no doubt that a clean, dry crawl space and/or basement is top priority for every employee at John's and we were happy to help. 

The major factors of the encapsulation were removing all of the debris, drying out the area, and encapsulating with the patented CleanSpace antimicrobial fiber. New drains were put in, along with Spray Foam insulation. Jim & Shirly were thrilled with the results knowing that their home is healthy and protected, and they even sent us photos of them in their newly encapsulated crawl space. 

Crawl Space rescue in Sherwood, OR

Out in Sherwood, Oregon, Danielle, and Jill had some major water issues going on in the crawl space of their home. The insulation had begun to sag and the humidity was pretty high overall. Our inspector, Vitaliy went to do a free inspection and quickly recommended encapsulating as the best remedy. They agreed and shortly after Ramon was out with his team to clean out the crawl space and do a full encapsulation using CleanSpcae, a SuperSump Plus, and Spray Foam insulation. 

Danielle and Jill are thrilled they no longer have to worry about any more issues or any further damage. and, as always we here at John's Waterproofing are stoked to have happy customers.


CleanSpace in Sherwood, OR

In Jerry's basement, there was some water seeping into one of the corners, and Jerry was very concerned about this and also didn't want anything getting worse so when he saw an advertisement for John's Waterproofing on TV he decided to give us a call. An appointment was made with Jack, who came out and looked at Jerry's basement and suggested to Jerry that encapsulating the basement and installing a new dehumidifier and sump pump would be the best way to go. Jerry agreed and shortly after that Jake and Delfino were out to do the work. A SaniDr Sedona Dehumidifier was put in to take all of the moisture out of the air and SmartSump Pump was put in that will continue to pump out any water giving Jerry a dry basement for many years.

Jerry is thrilled that he no longer has to worry about anything happening in his basement. 

Basement, Sherwood, OR

Jerry had a basement that had some water seeping into one corner and he was concerned about it becoming worse and causing damage. He wanted to be able to use his basement for storage but did not want his belongings to become damaged due to moisture. Seeing a commercial for John's Waterproofing reminded him about his concerns so he called and scheduled an appointment to have Jack come out to see where the water might be coming from. Jerry had an unfinished basement and definitely needed some waterproofing done. 

Marisol, our project coordinator got Jerry on the schedule with Delfino's crew and they were out in no time installing a new dehumidifier, sump pump and put in CleanSpace. This way Jerry now has a basement that he knows will stay dry and he is stoked that he now has a reliable, usable space that he can use for storage. 

Soggy Crawl Space, Sherwood, OR

This customer of ours in Sherwood, Oregon called asking for a crawl space check with concerns of mold. Pam has allergies and wants to do everything she can to be able to have clean air coming into her home.  Here at John's Waterproofing Company, helping provide customers with clean safe air to breathe is a priority so, of course, we happy to come out and take a look. 

Upon arriving our Design Specialist did, in fact, find some post rotting, soggy insulation, and some mold. There was also some standing water in the crawl space. Marcus suggested some crawl space repairs to the posts, CleanCpace encapsulation with a SaniDry Sedona dehumidifier, and a new sump pump. We also put in spray foam for the new insulation. Our crew was able to have this all completed for Pam in just a few days. 

Pam is now one happy customer, having the peace of mind that the air coming into her home is mold-free and will no longer affect her allergies. 


Clean Space the Neighborhood; Sherwood, OR

Nelson called us to encapsulate his crawl space after seeing our job well done on his neighbors home. He, however, didn't know just how lucky he was to call us at the time he did. His home was infested with mold in the crawl space. With 50% of the air, he and his family were breathing was coming from the crawl space. 

So our first course of action was to clean up all the mold and prevent it from coming back. And to do so we used our two-step Mold-X. Which cleans and seals the walls and posts from the spores growing again. 

Which made it so that when we started the installation of the TerraBlock and CleanSpace we wouldn't be locking it in and letting it flourish. Francisco and his crew also made sure to replace seal up the vent covers so that no new liquid could travel into the crawl space. 

With the vents covered, the customer was curious as to what would regulate the humidity levels. We reassure him everything would be fine, as we installed the SaniDry Sedona dehumidifier to regulate all humidity issues. And temperature fluctuations that may start due to weather changes. 

They also had the TripleSafe sump pump installed, which has a separate generator to power on in case of power outages. That would pump the water out of the crawl space completely. Leaving the customer satisfied knowing that they wouldn't have to worry about it not working randomly. 

Standing Water Transformation in Sherwood, OR

This customer called with concerns about the standing water in her crawlspace and what damage it was causing. She gave us a call for an inspection and to see what her options were to fix the issue. 

Our inspector went out and recommended we do a crawlspace encapsulation to secure and protect her crawlspace from water damage. Our crew went out and removed all the sagging insulation and old ripped vapor barrier. We installed our TripleSafe sump pump that has three pumps to ensure the high capacity of water drainage along with a WaterWatch Alert system that will sound off to notify you if there is a leak or any other issue to avoid minimal damage. We also installed a SaniDry Sedona dehumidifier that will keep the air clean of mold spores and dust mites but also keep the humidity down to avoid moisture in the crawlspace. Then we seal it closed with our CleanSpace liner that keeps water out and puncture resistant. 

She was so happy to have a dry crawlspace and not have to worry about water again. She can now enjoy her home knowing they are breathing clean air in the home.

Vapor Barrier Combination in Sherwood Oregon

This homeowner had a dirty and ripped vapor barrier that we came in to replace. Since they had such a large space they wanted to be able to use their crawlspace for storage. The homeowners were not quite ready to commit to a full encapsulation though, so they opted to use our 2o mill thick CleanSpace in the area in which they will be storing items and the thinner 6 mill plastic in the areas that do not get foot traffic. This allows them a sealed and usable space. 

Here at John's Waterproofing, we pride ourselves on our ability to be flexible without compromising safety and home health for our homeowners.

We need a vapor barrier installed in our crawlspace.
Vicinity of SW Roosevelt Street in Sherwood
We have a daylight basement on a sloping lot. It appears water is coming in under the foundation. The builder installed a sump pump in the lowest corner and it runs almost continually during the winter. There is also visible water running along some upper foundations in the crawlspace during heavy rains. There can be a moist smell in the basement when it is raining. Our backyard seems to be overly saturated in the winter too. It looks like bad drainage all around.
