Moisture Mapping is a critical aspect of building inspection and maintenance, aiming to identify areas with excessive moisture that can lead to structural damage, mold growth, and health hazards. Determining acceptable moisture levels is essential to ensure the longevity and safety of a property.

### What is a Normal Moisture Reading for Drywall?

Drywall is a versatile building material prone to moisture absorption, which can compromise its integrity. Establishing appropriate moisture thresholds aids in preventing costly repairs and maintaining a healthy indoor environment. Generally, acceptable moisture levels in drywall should not exceed 15%. Readings between 15% and 20% indicate elevated moisture content that requires further investigation and corrective actions. Readings above 20% signify excessive moisture, necessitating immediate remediation to prevent mold growth and structural damage.
