Do I have a problem?
If you see mold growing in your home you know you have a mold problem. However, mold often grows in places where it is not easily spotted, like inside walls, under floor boards, in attics and even inside heating and air-conditioning ducts. If you smell a musty odor you probably have mold growing somewhere. Even if you have a small area of mold, left untreated, it can grow out of control. The best approach to mold issues is a preventative one.
