You clean the floors, wash the curtains, scrub the walls, empty the closets, and maybe even buy a few air fresheners. Yet somehow, that musty smell keeps coming back.
It may disappear for a few hours—or even a few days—but eventually, you notice it again. The same earthy, damp odor is hanging in the hallway, coming from the basement, or lingering in a room that otherwise looks perfectly clean.
If this sounds familiar, there is a good chance you're dealing with more than a cleaning problem.
