Before & After Photos

You can never gain control of an interior space if you keep letting unconditioned, outside air into it. Most crawl space doors leak air and ones that are below grade leak water, and many people don't know that there is a real solution for this problem. These homeowners reached out because this crawl space was in need of several repairs and their exterior access was their main concern. We went out and thoroughly inspected it, and worked with the homeowners in created a game plan that will address all of these issues. We began the project and installed a full encapsulation with a perimeter drainage system and sealed all of the vents. We then installed our TerraBlock insulation and CleanSpace 20 mil liner in order to keep the crawl space dry, stable and healthy. This pairs with Spray Foam along the foundation walls and a SaniDry dehumidifier to maintain a healthy relative humidity throughout the space. To provide a clean and convenient access to the crawl space, we install our Turtl system. This is made of plastic so it will never rot, rust, or corrode and is built to last. This system combines the exterior crawl space access and an airtight door in one sturdy unit. It will keep animals, leaves, and weeds out of the well and one of the most important features is the ability for it to lock. It is fastened to the foundation with concrete screws. Now when the homeowners want to enter their crawl space they just lift the door up and go in through the clean inside of the Turtl. 

The dirt under the crawlspace in this home was so moist that it was a step away from being mud. Our crews went in and sealed up the crawlspace which protected the home from the moist dirt and prevented destruction to the home above. 

Partially done crawlspace was bothering customer, so they called us to finish it 

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.
