Drywall is a common building material that is susceptible to moisture damage. A normal moisture reading for drywall is between 5% and 8%. When the moisture content of drywall exceeds this range, it can lead to a variety of problems, including mold and mildew growth, drywall deterioration, and even structural damage.
Causes of High Drywall Moisture Levels
- Leaks in the roof or plumbing
- Poor ventilation in the home
- High humidity levels in the air
- Flooding
- Moisture from the ground
Consequences of High Drywall Moisture Levels
- Mold and mildew growth
- Drywall deterioration
- Structural damage
- Health problems (e.g., asthma and allergies)
How to Prevent High Drywall Moisture Levels
- Fix any leaks in the roof or plumbing
- Improve ventilation in the home
- Use a dehumidifier to reduce humidity levels in the air
- Install moisture barriers in areas that are prone to flooding
- Grade the ground around the home to slope away from the foundation
How to Repair Drywall Damage Caused by Moisture
- Remove any mold or mildew growth
- Cut out the damaged drywall
- Replace the damaged drywall with new drywall
- Seal the joints between the drywall with drywall tape and joint compound
- Paint the new drywall to match the existing drywall
Conclusion
Drywall is a common building material that is susceptible to moisture damage. A normal moisture reading for drywall is between 5% and 8%.
