Up to half of the air inhaled on the first floor of a home comes from the crawlspace. When you combine the moisture from the soil with the dark and dank conditions of a crawlspace, you have a noxious, destructive environment where mold thrives and spreads at an alarming rate across any organic material. Rot and decay set in and eventually lead to structural damage of floor joists and framing as well as other serious problems.
Encapsulation prevents moisture in the ground from penetrating into the crawl space area and potentially damaging the exposed wood and insulation. It also helps control humidity levels in your crawl space. In an encapsulation, we install a dehumidifier to better control the humidity in the area. If needed, a sump pump will be installed. The sump pump is placed at the lowest area and pumps any standing water out of the crawl space. A vapor barrier also guards against any crawl space moisture from becoming a breeding ground for mold and fungi, and could even help prevent the hardwood floors from warping.
