Upper Marlboro homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action.

Toxigenic mold species — particularly Stachybotrys — appear in Upper Marlboro properties with histories of water damage or chronic moisture.
