Mold can usually be seen or smelled. Mold may appear as slightly furry, discolored, or slimy patches that increase in size as they grow. Molds also produce a musty odor that may be the first indication it is present. The best way to find mold is to look for visible signs of mold growth or water staining, or follow your nose to the source of the odor. After flood waters recede you should check often for new mold growth or signs of moisture that may indicate the need for cleanup, home repair, or removal of affected materials.
