The old crawl space door has been replaced with a new door that does not warp, rust, or rot. A friction fit insulated interior door is installed before the exterior door is put on to keep out outside air and moisture.
This vented crawl space in Charles City, VA had falling and damaged insulation, a torn vapor barrier, high relative humidity, and mold growing on the joists. The vents and rim band were sealed and insulated, the sill plate was sealed, a vapor barrier was installed, and spray foam insulation was applied to the walls.
The ground cover in this crawl space was a 6-mil, a similar thickness to a trash bag, it is easily ripped and displaced. Because it is unsealed and has tears, the 6-mil ground cover allows moisture from the earth to affect the crawl space raising the relative humidity, damaging insulation, and causing microbial growth.
After removing the 6-mil, we installed a 20-mil heavy-duty vapor barrier called CleanSpace, and is similar to the thickness of a pool liner. CleanSpace has a built-in Antimicrobial called UltraFresh. When we install the vapor barrier, we overlap and seal all seams, seal the liner to the walls 6-8 inches above outside grade, and wrap and seal all piers. By sealing the CleanSpace at all of these points, we are able to isolate the crawl space from the earth's moisture.
Moisture has been wreaking havoc in this crawl space. Mold and mildew are growing on the floor joists and the insulation has fallen and is damaged from the moisture. Efflorescence and staining on the foundation walls tell us that moisture is not only entering through the open vents but also through the block walls.
The homeowner wants to seal and insulate the crawl space to prevent future moisture damage and microbial growth. We began by treating the mold and mildew growth with shockwave, and antimicrobial that kills the microbial growth. Then we set to cleaning the space out then sealing all vents, penetrations to outside through the foundation walls, and the sill plate. CleanSpace Vapor barrier is installed, wrapped and sealed around all piers, attached to the foundation walls, and sealed at all seams. Finally, the rim band is insulated and foam board insulation is installed on the foundation walls and sealed at all seams. A dehumidifier is installed to control the relative humidity and help prevent future microbial growth.
This Lanexa, VA client wanted to replace the gutters on their home with GutterShutter. This side of the home didn't have any gutters to start with.
