Fixing the Problem
- Before cleanup, stop the source of water. Otherwise, the mold will simply grow back.
- Use a disposable Type N-95 respirator to limit your exposure to airborne mold. These are available at many hardware stores and on the internet: $12 $25.
- If porous materials, like drywall or carpet and padding have been wet for longer than 48 hours, remove and dispose of those materials.
- Porous materials like drywall tend to remain wet, especially the bottom portion, even after the source of water is gone. If drywall has been wet for longer than 2 days, remove the affected drywall approximately 3 feet up from the floor.
- If removing drywall, isolate the room or rooms where the demolition is being performed with plastic, and use a fan to create negative pressure in the room.
- For non-porous materials (like bathroom tiles) and semi-porous materials (like wood), clean the materials. After the area is cleaned, dry it completely.
- If mold reappears, the source of water has not been eliminated.
Consider hiring an environmental health professional or industrial hygienist to define the problem and a trained contractor to clean it up. Checking references to make sure the contractor has experience cleaning up mold.
