Tribal IAQ Resource Directory: Mold and Moisture

Overview

The key to mold control is moisture control. To prevent mold from growing, it is important to find the water source and fix the problem. Dry the area quickly, within 24-48 hours if possible. Remove bulk water, and use fans and dehumidifiers to speed drying, and/or open doors and windows if outdoor conditions allow. Keep the humidity levels below 60% to prevent the mold from growing. Once the area is dry, it is important to clean and remove the mold. Clean the mold off hard surfaces using a mild detergent and water. It is not recommended to use biocides (e.g. bleach) to remove mold. Absorbent or porous materials, such as ceiling tiles and carpet, may have to be thrown away if they can’t be cleaned and dried. When cleaning mold, it is important to use personal protective equipment including gloves, an N-95 respirator, and goggles.

IAQ Tip:

Major mold events, or mold areas larger than 10 square feet may require professional remediation.

First, address moisture problems...

  • Promptly fix the source of any water problems or leaks.
  • Keep indoor humidity low. If possible, maintain indoor humidity below 60% (ideally between 30-50%) relative humidity.

Then, address the mold...

  • Clean mold off of hard surfaces with water and detergent, and dry completely. Items that soaked up water may need to be discarded.

If you are experiencing health symptoms that you think are caused by mold in your home, consult a healthcare professional.
