This Jeffersonton, VA homeowner has suffered from high humidity in the basement of their home for years. The basement is attached to a low ceiling crawl space built on a slab. The high humidity is typically caused by:
1. Drainage of ground water from outside.
2. Hydrostatic water table pressure coming up from below.
3. Hot/humid air coming into the basement and hitting cold surfaces.
These before and after photos show how Comfenergy solved the humidity issue. A perimeter drainage system was installed in the slab around the perimeter of the crawl space. CleanSpace (20 mil) vapor barrier is tucked behind the perimeter drain. Then Thermax foam wall panels are installed to provide the proper air sealing and insulation value. Thermax also provides a thermal barrier for fire protection and meet codes.
Now the basement and crawl space are nice and dry!
A homeowner in Brandy Station, VA had inefficient insulation in their attic and they wanted to make their main floor more comfortable. To fix this issue, we removed all of the old yucky insulation, air sealed the attic by closing all penetrations and top plates using polyurethane foam, and then we blew in TruSoft cellulose insulation to an R value of 49. This resulted in a much more comfortable main floor, as much less conditioned air could now escape from the attic.
