Basement Mold
Where to Look for Mold in the Basement
Mold grows on organic materials, such as paper, dirt, wood and soap scum. Mold grows on moist materials, so mold growth is likely in areas wet by water leaks, flooding, humidity levels above about 70 percent and condensation. Any flooded area that was not completely dried within about one day is likely to have mold growth. Walls need to be opened and rapidly dried to prevent mold growth. Any area that is stained from water should be examined for mold growth. Peeling paint may be an indication of wet walls.
Moisture seeping through concrete walls and floors will cause moist conditions likely to cause mold growth on or in walls, carpeting and materials stored in the basement. Mold often grows under cabinets, behind base-boards, inside walls, in carpet padding and under vinyl wall coverings.
An un-vented clothes dryer creates a very humid, warm environment conducive to mold growth. Closets may have mold growth if clothing is damp or if there is a cool outside wall in the closet. Also, there is a chance mold might be growing behind furniture, particularly against an outside wall.
Mold will not normally be found in furnace or air-conditioning ducts unless they were flooded because the heated or air-conditioned air is very dry.
Moisture coming through a basement floor or wall may deposit a light-colored salt and other minerals
that are sometimes thought to be mold. The deposits should quickly dissolve and disappear when wet with water if they are a salt.
Basement Mold Removal
Since people react to mold whether it is living or dead, the mold must be removed.
It is impossible to completely remove mold from porous surfaces such as paper, Sheetrock (drywall) and carpet padding, so these materials should be removed and discarded.
Preventing Mold Growth
The moisture problem must be fixed to prevent future mold growth. Since there are some mold spores everywhere and since mold grows on any wet organic surface, the only way to prevent mold growth is to keep things dry.
Air Cleaners
Air cleaners will not solve a mold problem. A high-efficiency air filter that removes mold spores may reduce the number of spores in the air, but mold spores rapidly settle onto surfaces, such as the floor, where air filters cannot remove them. Filters may reduce the number of mold spores in the air but are not substitutes for removing the mold. Air cleaners that produce ozone are not effective at eliminating mold. Ozone is a lung irritant that should not be in an occupied space.
