To control the heat and cold impacting the room on the other side of this knee wall space, we installed rigid foam board insulation. This will reduce the heat transfer between the living space and the attic, leaving the living space more comfortable throughout the year.
This Bruington, VA client contacted us about repairing moisture damage in their crawl space. Moisture had caused mold and mildew growth, was absorbed in the insulation which held it against the floor joists, the material began to delaminate and fall away from the floor.
All debris and insulation was removed from the crawl space, microbial growth was treated, the vents, sill plate, & rim band were sealed, the foundation walls were insulated with closed cell spray foam insulation and a dehumidifier was installed to control the relative humidity. The homeowners no longer need to worry about moisture damage in their crawl space and have the added benefit of warmer floors in the winter and reduced drafts in the home.
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.
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.
This homeowner had concerns about water entering their crawl space. At our inspection one of the concerns, we found that the existing vapor barrier was not sealed, allowing moisture in. As part of the solution, we installed a 20mil Heavy-duty, Vapor Barrier with UltraFresh Antimicrobial built-in, called CleanSpace. We ran it up the walls sealing it and leaving a 2" viewing strip for a termite inspection and sealed and wrapped all the piers.
