- Clean up any leaks or spills right away. If moisture is removed within 24-48 hours of appearing, mold is unlikely to grow.
- Check your roof and repair or replace it immediately if you detect a leak; also repair any cracks or openings in your siding, and make sure your rain gutters are clear of debris and functioning properly.
- Make sure the ground around your home slopes away from the building, not toward it.
- Properly insulate your walls; this will help keep condensation from forming on your interior walls.
- If you see condensation around windows or on walls or pipes, dry the wet surface and reduce the moisture source. If you have condensation, it could be a sign of high indoor humidity.
- Keep indoor humidity low, ideally between 30 and 50 percent. You can find humidity meters at most hardware stores.
- Properly vent appliances that produce moisture, including clothes dryers and stoves.
- Run a bathroom fan when showering, and a range hood when cooking or running the dishwasher. If you don’t have fans, open windows.
