As flood waters from recent inclement weather recede, the potential for mold growth in homes and businesses may become prevalent.  Damp conditions from flooding create the perfect breeding grounds for mold to grow, which can happen as soon as two days after flooding.  It’s important to dry out your home or business as quickly as possible to avoid costly repairs and health issues in the future.

Molds are simple microscopic organisms found virtually everywhere, indoors and outdoors. When airborne mold spores are present in large numbers they can cause allergic reactions, asthma episodes, infections and other respiratory problems.

People who are at higher risk from the effects of mold include infants and children; older Pennsylvanians; people with compromised immune systems because of HIV infection, liver disease, or chemotherapy; pregnant women; and individuals with existing respiratory conditions such as allergies, multiple chemical sensitivity and asthma. People with these conditions should consult a physician if they are experiencing health problems.

Exposure to mold can occur during floodwater cleanup. To minimize exposure, use a mask or respirator, wear rubber gloves and take breaks in a well-ventilated area.

Here are some helpful tips for cleaning mold:

Identify and correct the moisture source. Then clean, disinfect and dry the moldy area. Keep the area well-ventilated and dispose of anything that has moldy residue, such as rags, paper, leaves or debris.

Porous materials can trap molds. Items such as paper, rags, wallboard, ceiling tiles, sheetrock, carpeting and rotten wood should be thrown out.

Wear protective gloves, such as rubber dishwashing gloves, when working with moldy materials.

Carpeting can be a difficult problem. Drying does not remove the dead mold spores. If there is heavy mold on the carpet, the best course of action may be to throw it away. If the area was flooded, remove sheetrock to at least 12 inches above the high water mark. Allow the area to dry for two or three days before replacing damaged materials.

Use non-ammonia soap or detergent, or a commercial cleaner in hot water. Scrub the entire affected area thoroughly using a stiff brush or cleaning pad, then rinse with clean water.

After thorough cleaning and rinsing, disinfect the area with a solution of no more than one cup of bleach in one gallon of water. Never mix bleach with ammonia because the fumes are toxic. Allow areas you are disinfecting to dry naturally overnight to kill all molds.
