Mold thrives in moist environments, and drywall is no exception. At what moisture level does mold grow in drywall?

Mold can begin to grow on drywall when the moisture content reaches 15%. This can occur due to various factors, such as water leaks, high humidity levels, and condensation. Once mold takes hold, it can quickly spread throughout the drywall, causing structural damage and health issues.

To prevent mold growth, it is crucial to keep drywall dry by addressing any sources of moisture. This includes repairing leaks promptly, maintaining proper ventilation, and using a dehumidifier to reduce humidity levels.

The following are some telltale signs of mold growth in drywall:

• Visible mold colonies (often black, green, or gray)
• Musty or moldy odors
• Discoloration or staining on the drywall
• Buckling or warping of the drywall
• Health problems (e.g., respiratory issues, allergies)

• Addressing Mold Growth in Drywall

If you suspect mold growth in your drywall, it is essential to take action promptly. The following steps will help you address the problem:
