High humidity and moisture in the crawl space promotes the growth of mildew and mold that can cause structural damage and unhealthy air below the sub floor that seeps into the home environment. Encapsulating or conditioning a crawl space creates an environment that can be controlled. Controlling the environment in the crawl space prevents moisture and humidity from entering the crawl space preventing mold, mildew, and unhealthy air, which can be detrimental to a home owner.
