Mold can thrive anywhere there is moisture and organic material (like wood) that it uses as a 'food' source. That makes a crawl space an ideal haven. Encapsulation and dehumidification are the keys to getting rid of mold problems and their accompanying smells. Our CleanSpace vapor barrier will protect your crawl space from moisture coming in through the walls and floor in your crawl space. Adding a SaniDry dehumidifier (like the new Sedona) takes care of any remaining ambient moisture, which makes your crawl space unhospitable to mold.
