Crawl Space Repair Before & After Photos

This homeowner in King City had another company come out and work on their crawlspace and after a few years, a cable installer showed them photos of their crawlspace. They were disappointed to see the entire space covered in a thick and sloppy layer of spray foam insulation covering everything in their crawlspace. 

Our crews came in and removed the old insulation and installed a CleanSpace vapor barrier and then applied the spray foam properly around the foundation of the space so that the homeowner and workers could still access the space and work when needed. 

When a dirt crawl space does not have a proper vapor barrier, moisture from the soil rises, causing humidity all throughout the home. This introduces musty and damp odors, as well as creates the perfect environment for pests and rodents to thrive. This homeowner contacted John's for a free inspection after finding that their vapor barrier was damaged and lost its protective value. We sent one of our knowledgeable system design specialists out, and after inspecting the crawl space he met with the homeowners to go over the best option to properly protect this crawl space.

We began by removing all of the debris. Then, we dug a trench around the interior perimeter of the crawl space in which we installed a 3 inch perforated pipe into a silt sock. This will create a secure passage for the water to drain to the lowest point. At this low point, we installed our SuperSump Plus to collect all of the water and pump it outside of the home away from the foundation through a discharge line. Each wooden post is jacked up with a bottle jack to install our CleanSpace system between the footing and the post to protect the wood from water damage. Next, we covered and sealed all of the vents to prevent outside air from entering. Then, we installed our TerraBlock system which provides an insulated barrier between the home and the earth. After, we anchored our 20 mil-thick-liner; CleanSpace into the foundation walls up to the rim joists and on top of the TerraBlock system and sealed it to the footing of the wooden posts with our waterproof tape. To keep the environment controlled we installed our SaniDry Sedona that will dry and filter the air to eliminate damp and musty odors as well as keep the space at a healthy relative humidity. To finish this project we sprayed our foam insulation onto the foundation walls up to the rim joists, making sure every crack and void is filled- ultimately providing a completely airtight seal. With this full encapsulation, this homeowner can be sure they are protected for years to come. 

This customer called needing her house posts replaced in the crawlspace. We replaced them with our inorganic smart posts that will never rust, break down, or rot like traditional posts. 

Protecting the wooden posts in the crawl space is extremely important in maintaining the structural integrity of the home. This helps to prevent water from getting absorbed into the woods material and eventually leading to wood rot or mold growth. One way John's Waterproofing ensures that the wooden posts are isolated is with vapor barriers. We make sure to install the 6 mil vapor barrier between the concrete footing and the wooden post so that water won't have access to seep up in the post and damage it. Each seam of the vapor barrier gets overlapped so water can't seep over top of it and it is anchored to the foundation walls to prevent it from moving around. In order to safely protect your homes health, it's important to keep the crawl space dry and protected.

We encapsulated this crawlspace and installed a waterproofing system to transform this wet and gross crawlspace to a dry and clean space.
