Crawl Space before
Crawl space with a dirt floor, it has a moisture problem, it is wet in the summer and cold in the winter. Smells moldy, and causes rooms above the crawl to be uncomfortable.
Crawl Space after
The completed crawlspace, with a floor encapsulation and 2" foam board on the walls. This should correct the mold smell in addition to making the space above more comfortable.
Custom built fan cover
Whole house fans were conceived as a way to keep air circulating through a home. Unfortunately, they don't do much beyond actively pull conditioned air into the attic when they're running, and passively allow air to leak through when they're off! At least their heart was in the right place. We built a custom cover out of 2" foam board, sealed along the joints and gasketed along the bottom, ensuring that air will no longer leak through the frame and grate of the fan.
