It is very common for homeowners to have a moldy or mildewy smell in their basement that is very hard to locate. There can be many causes of such smell and the tracking alone can make some a little queasy. Sometimes these problems can only be determined by having the area looked over by professionals. Basement Detective is the DC area company capable of determining the source of the condition(s) that can cause mold growth.
