Crawl Space Repair Before & After Photos

Professional waterproofing of a sloped crawl space is absolutely imperative, as water intrusion into the space causes erosion and weakening of the soil that the foundation walls and footings, and subfloor posts rely upon for stability. As this erosion progresses, structural components beneath the home begin to shift, causing critical instability throughout the home. This home was feeling the threat of these issues, and to address them head-on, the owners scheduled a free inspection with the local experts here at John's. We have been waterproofing and repairing crawlspaces in the PNW for over 50 years, giving us the knowledge and expertise to protect homes and families from the devastating effects of water damage. 

When our crews arrived to encapsulate this crawl space, the first step was cleaning out the entire space - removing all debris, and leaving a nice clean space to work. Next, several different professional-grade waterproofing components are installed to protect the home. When the Encapsulation is complete, the entire crawl space will be 100% sealed, waterproofed, and insulated to professionally prevent water intrusion from further inflicting the home.

Inside of the encapsulated crawl space, our Electrical Division installs dedicated outlets for the two mechanical aspects of the system; the dehumidifier and the sump pump. The SaniDry Sedona Dehumidifier will maintain a safe relative humidity level, while also preventing the growth of mold, and removing allergens, moisture, and toxins from the air. This machine not only creates a health crawl space, it also creates a healthier home, by ensuring that the air that enters the home through the crawl space is clean. The TripleSafe Sump Pump, will expel all collected ground water far away from the home via an underground discharge line. Our heavy-duty Triple Safe System features 3 pumps inside of 1 canister - promising more than adequate water expulsion capabilities. This Pump System also features a fully battery-operated 3rd pump, ensuring functionality even in the event of a power outage. Because John's professionally encapsulated crawl spaces are 100% air-tight, and completely sealed and waterproofed, they transform wet, dreary crawl spaces into clean, dry areas that can be safely used as dry storage.

Insulation is an important step to keep moisture out of your crawl space and help with your homes energy efficiency. At John's Waterproofing we are able to completely seal the crawl space off from the earth and add moisture protection with TerraBlock insulation. TerraBlock is a 3/4 in. thick and puncture-resistant foam that insulates and helps control the environment in the crawl space. The earth is naturally always cool and applying the TerraBlock helps to keep the temperatures the same year round so that your homes heating/cooling systems don't have to work as hard to keep up with the changing climates, which leads to lower energy bills. It is made of materials that won't rot or grow mold which helps to keep moisture out. It is installed along the crawl space floor and is cut to perfectly fit into each individual space. We seal the TerraBlock in the crawl space with 4 in. thick waterproof tape and anchor it to the base. This ensures that groundwater can't rise up over top the insulation and evaporate into the air causing higher humidity levels. Overall, insulating the crawl space floor is an important step for our encapsulation system to keep your home dry and healthy. 

This homeowner had been dealing with moisture issues, drooping fiberglass, and returned critters. After noticing the issues kept coming back, they knew the would need a long term solution to keep the problems away. For this they called up John's Waterproofing to learn more about a full encapsulation. 

When a neglected area such as a crawl space gets water intrusion, it can create moisture that leads to mold and mildew growth. This will begin to affect the air quality in the home, damage the fiberglass insulation and create wood rot, damaging the structural integrity of the home. During this crawl space inspection we found mold on the subfloor and had the right solution in mind. Soda Blasting is an eco-friendly way to remove mold. This process uses compressed air to spray sodium bicarbonate (baking soda) and physically removes the mold and deodorizes the surfaces, leaving the subfloor clean and free of mold without causing any structural damage. Before installing the full encapsulation that this crawl space needed, we properly seal off the crawl space from the home to prevent baking soda from going up into the home and we then use our soda blasting machine to spray the areas with mold until it is looking brand new. Now that this mold is removed, we can then install our full encapsulation that will help in protecting this crawl space from any future mold growth. 

This customer called because they had a musty smell coming into their home from their crawlspace. The crawlspace was dusty, had some moisture on the vapor barrier, and had a strong musty smell. Our crews went in and encapsulated the crawlspace using our CleanSpace Vapor barrier. It is 20 mils thick and is rip resistant to keep animals and bugs out. We also installed our SaniDry Sedona dehumidifier to help keep the moisture out of the crawlspace and filter the air. After encapsulating the crawlspace the homeowner was so relieved that they didn't have a musty smell coming into their home.
