Water damage is every homeowners biggest nightmare. It can cause the wooden posts supporting your home to rot, increases exposure to mold growth, and structural damage can cost homeowners thousands. Good thing at John's Waterproofing our encapsulation process helps to keep your crawl spaces dry and healthy so that water can't cause any damage. The most important step in the encapsulation system is removing everything in the crawl space that has been water damaged. Usually that means we are taking out falling fiberglass insulation and the destroyed vapor barrier. Once everything is cleared out, we can install a proper drainage system. We dig a trench along the interior perimeter of the crawl space and lay a perforated pipe. This pipe can collect any water that tries to enter and offers it a safe passageway to a drain. For this encapsulation we installed a SmartDrain to collect the water from the pipe and send it away from the homes foundation. This system helps to keep the crawl space dry and avoid standing water. Afterwards, we install TerraBlock along the entire base of the space. This is a thick insulation foam that seals the earth from the house. It helps insulate and promotes energy efficiency because it regulates the environment. Next, a CleanSpace vapor barrier is installed on the base, up the foundation walls, and between the footing and wooden posts to isolate and protect. This vapor barrier differs from code regulated barriers because instead of only being 6 mil thin, it is 20 mil thick. It helps keep water from seeping over top and getting into the crawl space. A SaniDry dehumidifier is installed that filters the air by pulling out any particles or moisture. Lastly, Spray Foam is applied along the foundation walls to insulate and air seal the space. Once the encapsulation is completed, it has a clean look while also keeping it dry and healthy.
This homeowner found some concerns with the support in their home and decided to inspect their crawl space. In certain areas, doors weren't closing properly and the floor felt like it was sagging. This was occurring due to the the wooden posts in the crawl space being water damaged and deteriorating. Once the wooden posts absorb moisture, they begin to rot and mold. This makes them unstable and unable to properly support the home. At John's Waterproofing, we are able to fix this issue with SmartJacks. These are steel adjustable piers designed to stabilize the home in areas where the wooden posts no longer can. They are made of materials that won't rot or grow mold, which helps make them durable during any situation. Each year they can also be adjusted to ensure the home is staying steady and supported. Now, this homeowner feels much safer in their home knowing that the foundation is supported and secure.
This homeowner had reached out to John's Waterproofing back in 2015 about getting their crawl space inspected. They noticed that during the rainy seasons water would seep inside the space and puddle. Because of this, the water would bring in dirt and debris from the outside and leave it behind on the vapor barrier as the water evaporated. We explained that a full encapsulation would prevent these water issues from continuing and they decided to wait and see if the issue resolved itself. Then, in 2025 the same homeowner reached back out saying that the water issues they were experiencing had only worsened and agreed to encapsulate the space. A full encapsulation is the process of sealing the crawl space off and controlling the environment to help prevent water intrusion, mold growth, and wood rot. It involves installing a drainage system with a TripleSafe sump pump, TerraBlock insulation foam, and a CleanSpace vapor barrier. Now, this beautiful crawl space is capable of keeping water out and the home healthy.
Keeping your crawl space dry and healthy is extremely important in order to maintain a healthy home. If water gets into the crawl space, this can result in atmospheres for mold to grow, wood to rot, and poor air quality to waft into the living spaces. In order to protect your crawl space, John's Waterproofing recommends getting them fully encapsulated. An encapsulation begins by removing the damaged vapor barrier and clearing out any debris. Once everything is removed, then we install a drainage system. This involves installing a perforated pipe along the interior perimeter of the crawl space so that it can collect water from the ground or walls that try to seep through. It offers a safe passageway for that water to be sent to a SuperSump Plus sump pump. The sump pump is what works to take all that collected water and securely pushes it out of the crawl space and away from the homes foundation. Once there is control of water, then we can install TerraBlock. This is a thick insulation foam designed to seal the earth off from the home and regulate the environment. On top of the TerraBlock, a CleanSpace vapor barrier is installed. This vapor barrier differs from code-regulated ones because it is 20 mil thick and backed by a 25 year warranty against rips and tears. We also install CleanSpace up the foundation walls and between the footing and wooden posts to isolate and protect from water damage. Once everything is sealed with waterproof tape, then we can install a SaniDry Sedona dehumidifier. This helps to filter any moisture or particles out of the air, thus promoting better air quality in the living spaces. The final step would be applying Spray Foam to the foundation walls as a final air sealant and insulator. Now, this encapsulation will protect the home against water intrusion so that it can stay dry and healthy for its occupants.
The owner of this commercial building was getting a lot of complaints from the tenants about musty smells and humidity issues, so they called John's Waterproofing to get a free estimate and inspection. The owner met with our system design specialist after the inspection and went over options. They chose a full encapsulation for this massive crawl space. To begin this project we start by removing all the debris in the space. Next we dig a trench around the interior perimeter of the entire crawl space and lay down a perforated pipe into a silt sock to secure a safe passage for water to drain to the Sump pumps. We installed our SuperSump Plus with our UltraSump battery backup at the lowest point. Then, we installed a discharge line outside and away from the foundation. One of the retaining walls was crumbing, so we poured a new concrete wall to ensure the space remains on solid soil. We then install our TerraBlock system. This goes directly on the dirt floor of the crawl space creating an insulated barrier between the building and the earth. On top of the TerraBlock, we install our CleanSpace system. This goes all along the foundation wall and covers the entire crawl space floor. Lastly, to help with the humidity and musty smells, we install 2 of our SaniDry Sedona dehumidifiers. It will eliminate damp odors by drying and filtering the air, all while promoting healthy air throughout the entire building.
This crawl space was completely flooded and was creating multiple issues for this home. Wanting a permanent solution, this homeowner reached out to John's Waterproofing to get the job done. We sent out one of our system design specialist to perform a free inspection and estimate. After the inspection, our design specialist met with the homeowner to discuss solutions for this space and they agreed a full encapsulation would be the best option for this nasty, wet space. To begin, we removed all the debris and damaged fiberglass insulation. Since this crawl space had a lot of standing water, we had to dry out the space. All the water in the space caused a lot of moisture and humidity, which led to some mold growth, so we spot treated the mold stains with our highly effective cleaner, Mold-X2. We then dig a trench around the interior perimeter of the crawl space to lay down a perforated pipe into a silt sock. This will secure a safe passage for the water to drain to the SuperSump Plus pump at the lowest point. We install a discharge line outside to drain the water away from the foundation. Our LawnScape outlet is connected to this line. It is a grated drain that allows water to pass through but keeps debris out of the discharge line. We then install a RainDrain, which will collect water before it gets to the home and will drain it away. Next, we install our TerraBlock system. This goes directly on the dirt floor of the crawl space creating an insulated barrier between the home and the earth. With this barrier, it will keep moisture from making its way up through the crawl space flooring. On top of the TerraBlock, we install our CleanSpace system. This goes all along the foundation walls, up to the rim joists and is sealed at the footing of the wooden posts with our waterproof tape. All the vents in this crawl space are then sealed. This will prevent outside air from entering the space. Then, we install our SaniDry Sedona to control the environment. This effective dehumidifier will eliminate damp, musty odors by drying and filtering the air, and will keep the home at a healthy relative humidity. To finish this project, we install our foam insulation. This is sprayed all along the foundation walls, up to the rim joists ensuring an airtight seal in this space.
This homeowner was struggling with strong odors coming from their crawl space so they wanted to find a solution that would permanently solve this issue. They reached out to John's Waterproofing to get the job done. After sending our system design specialist to perform a free estimate and inspection, he met with the homeowner to discuss options for this crawl space. They decided an encapsulation would be the best way to go. Not only does it improve air quality in the home, it also offers protection from mold and mildew and increases the home's value. It also reduces energy costs by creating a barrier against moisture and air leaks, which will help maintain a consistent temperature in the home. To begin this project we start by removing all the debris in the space. Since this space did not have much water, we installed our SmartDrain system. This will alert the homeowner of a possible plumbing leak with an audible alarm and will drain the water into a drywell underneath the CleanSpace until the homeowner can address the leak. Then, we install our TerraBlock directly on the dirt floor of the crawl space and this will create an insulated barrier between the home and the earth. On top of the TerraBlock, we install our CleanSpace system all along the foundation walls, up to the rim joists and seal all the vents in the space to ensure no outside air enters. We make sure to seal the CleanSpace with our waterproof tape against the footing of the wooden posts. We install our SaniDry Sedona to control the environment and this will eliminate the damp musty odors the homeowner was concerned about by drying and filtering the air. It will also keep the space at a healthy relative humidity. The final step is to install our foam insulation. We spray the foam along the walls of the foundation, up to the rim joists providing a well insulated and airtight crawl space for this homeowner.
This homes crawl space had the old fiberglass falling, and it smelled very musty. The owners of the home were concerned about the health risks that could be occurring by living with this kind of mess under their feet. To get assistance, they called up John's Waterproofing so they could learn about what they could do. This is how they learned about encapsulation. The owners were sold on this solution; energy savings, indoor air benefits, and overall health benefits for the homes longevity. We pulled out the old vapor barrier, fiberglass, and general debris. We then installed drainage, a sump pump, and insulated with TerraBlock and Spray Foam. We use a CleanSpace vapor barrier, and installed a SaniDry dehumidifier. Now this space is dry and healthy.
This homeowner was noticing a musty smell throughout their home, and felt like their home was having issues retaining heat in the winter, and cold air in the summer. They went to check their crawl space and found that there was standing water, and most of their fiberglass insulation was falling from the ceiling of their crawl space. They called John's Waterproofing to get a free inspection and estimate. After our system design specialist was done with the inspection, he met with the homeowner and after discussing solutions, they decided that a crawl space encapsulation was the way to go. To begin this project, our team goes in and removes all the debris like the fallen fiberglass and damaged vapor barrier. Next, our team digs a trench around the interior perimeter of the crawl space to then lay down a perforated pipe into a silt sock. This will secure a safe passage for the water to drain to the SuperSump pump at the lowest point. Our SmartDrain system is also installed, this backup system will alert the homeowner of a possible plumbing leak with an audible alarm and drains away the water into a drywell under the CleanSpace until the homeowner is able to get it fixed. Our team then installs our TerraBlock directly on the dirt floor of the crawl space. This acts as an insulated barrier between the home and the earth that will keep moisture from making its way up through the crawl space floor. Next our team installs CleanSpace, which is placed on top of the TerraBlock system, on the foundation walls and up to the rim joists. All the vents in the crawl space are sealed to prevent outside air from getting in. Our team then installs our SaniDry Sedona dehumidifier which will control the environment and pull out any moisture. This will promote clean healthy air through the entire home by eliminating damp musty odors by drying and filtering the air. To finish this encapsulation our team sprays our foam insulation along the foundation walls, up to the rim joists. This homeowner can now be sure that their energy costs will lower and the air they're breathing is healthy and clean. A protected crawl space not only benefits the health of the homeowner but the longevity and health of the entire home for years to come.
This homeowner was having issues with water in their crawl space, it was creating mold and mildew so they were wanting a solution fast, they called John's Waterproofing. After getting a free estimate and inspection, the system design specialist sat with the homeowner and went over the details of the findings and explained to the homeowner that the best solution to keep their crawl space dry and healthy was an encapsulation. To start this encapsulation we had our team remove all the debris from the crawl space. This crawl space had mold in some areas so we used our Mold X2 to spot treat it. Mold X2 is a highly effective cleaner for contaminated surfaces like wood. Once the mold is taken care of, the next step in this project is to install our drainage system. We start by digging a trench around the interior perimeter of the crawl space then we lay down a perforated pipe in a silt sock that will ensure water has a secure passage to the TripleSafe sump pump system that we installed. A discharge line is installed as well to pump the water outside. Next, our TerraBlock is installed directly on the dirt floor creating an insulated barrier between the earth and the crawl space. Our CleanSpace system is directly installed on top of the TerraBlock and up to the foundation walls and under the footing of the posts. All vents in the crawlspace are sealed shut.
Our SaniDry Sedona dehumidifier is installed to pull out moisture and keep this crawl space dry and at a relative humidity of 55% which will help prevent mold and mildew. To Finish this project, we spray foamed the foundation and this will ensure the space is air sealed and completely protected.
