The first line of moisture defense for any home is the vapor barrier in the crawl space. Often times vapor barriers are installed incorrectly and do not supply the appropriate level of moisture protection. A continuous vapor barrier with overlapping edges can effectively keep the moisture level low enough to prevent wood damage, mildew, bacteria or mold from growing in your crawl space. This, in turn, lowers the probability of those problems entering your home. Some vapor barriers are only installed in the center portion of your home and do not provide adequate moisture protection along the edges of the foundation or the edges of interior piers in the crawlspace. Vapor barriers should be installed all the way to the edges of the foundation walls and edges of the piers. In particularly damp areas around lakes, ponds, rivers or other bodies of water, vapor barriers in crawl spaces should be sealed to the foundation wall between 6” and 12” inches to ensure the lowest possible amount of moisture is able to enter your crawl space area.
