Chronically damp or wet basements are a common problem. According to statistics published by the American Society of Home Inspectors, a nonprofit professional association, about 60 percent of the houses in the United States have moisture problems.
Wet basements and damp crawlspaces are not only a nuisance, they are a recipe for larger, more costly problems in the home if untreated. Basement flooding aside, moisture alone is often responsible for ruining drywall, framing, carpeting and furniture. If your basement is unfinished and used primarily for storage, moisture may cause your tools to rust, clothing to stink, or pictures to wither.
