Crawl spaces are generally damp, humid environments that if not treated correctly can cause mold and bacteria growth. This nasty crawl space air will then travel up and into your home causing odors and an unhealthy environment. Treating your crawl space as a part of your home and not ignoring it is vitally important to your health and the health of your home. Once crawl spaces are properly sealed, dehumidifying the air will give you back the control of your crawl space environment.
