How to prevent mold

Mold needs moisture. Controlling humidity and fixing leaks quickly is the most effective prevention.

Control moisture

Fix leaks promptly, vent bathrooms and kitchens, and use dehumidifiers in humid spaces. Keep indoor humidity between 30–50%.

Dry wet areas fast

If water gets in, dry it within 24–48 hours to reduce mold risk. Use fans and a dehumidifier, and remove soaked materials that can't be dried.

Watch the common spots

Check around the toilet, under sinks, basements, and around windows and HVAC for condensation or leaks — the most common mold hotspots.
