This customer had high humidity levels in his home -- condensation on windows, allergy problems... Notice the wet gravel on the crawlspace floor. The fiberglass blanket on the crawlspace wall had absorbed a TON of water, and was so heavy that it was falling down.
We installed drainage matting and bright white "CleanSpace" on the floor, and foil-faced rigid foam board insulation on the walls. The result is a clean, dry environment beneath the house, which means drier air in the home above, too.
