Before & After Photos

This Lake Oswego crawl space was coated in mold and drenched with standing water. It was a hazardous zone, sending unhealthy air up into the home. The homeowners reached out to John's Waterproofing for an inspection and to help them decide how to protect their home and family without putting a dent in their wallet. After one of our Design Specialists took a look down under, they discussed with the family and made a plan that implemented to address the major issues at hand. Shortly after, the project went underway.

Our Waterproofing Experts removed all debris from the crawl space: the raggedy, moldy vapor barrier, and standing water. Then our crew performed Soda Blasting, sending high-pressure baking soda, to neutralize and eliminate mold growth. Once the mold was taken care of and the dirt floor was unveiled, a trench was dug along the interior perimeter of the space, and a Perf Pipe was inserted. This drainage system sends collected groundwater to the sump pump and is wrapped in a silt sock to ensure no debris can enter and clog the pipe. This led to the installation of a SuperSump Plus, a sump pump system that pumps water out from the crawl space with a discharge line attachment. The water intrusion had finally been taken care of, so lastly, a fresh 6-mil vapor barrier was attached to the floor to trap moisture from rising through the dirt. The homeowners felt relief knowing the mold and standing water had been addressed, giving their crawl space a cleaner and safer environment beneath the home, and protecting the family above.

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. 

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 homeowner was looking to sell their home and found that their crawl space was not in the best shape, and was full of standing water-so they called John's to set up their free inspection. Our real estate response team then went out and after inspecting the crawl space, he went over the findings and wrote up an estimate. Due to all of the water in the crawl space, we begin by drying it out to then remove all of the debris along with the old vapor barrier. Next, we dig a trench around the interior perimeter of the crawl space in which we lay down a 3 inch perforated pipe into a silt sock to secure a safe passage for the water to drain to the low point. Then, at this low point, we install our SuperSump Plus which will collect all of the water and pump it outside of the home via discharge line. Next, we install our TerraBlock system onto the floor to create an insulated barrier. On top of the TerraBlock is our CleanSpace system which is our 20-mil-thick, pool like liner that is anchored along the foundation walls up to the rim joists and sealed at the footing of the wooden posts with our waterproof tape. We also make sure to cover all of the vents so outside air does not enter. To keep the environment controlled, we install our SaniDry Sedona. This is the most effective dehumidifier on the market for its size and will eliminate damp and musty odors by drying and filtering the air all while keeping the home at a heathy relative humidity. Lastly we install our foam insulation. This is sprayed along the foundation walls, up to the rim joists filling every crack and void to ensure a complete airtight seal. Not only is this home now fully encapsulated and protected from water intrusion, but the new homeowners will be saving on energy costs. This home can now be confidently put on the market to sell. 

Spray Foam is a type of insulation that goes along the foundation walls in the crawl space. It is made of materials that expand and grow to fit into every crack and crevice along the walls. The purpose of Spray Foam is so the crawl space can be completely air sealed and it helps in insulating the home. By air sealing the crawl space, this actually helps the home become more energy efficient because it reduces heat loss, lowering energy bills. Overall, Spray Foam is an ideal insulation solution in the crawl space compared to the traditional fiberglass insulation in order to keep your home dry and healthy.
