Moisture Mapping Understanding Acceptable Moisture Levels in Drywall

Moisture mapping is a crucial process in assessing the health of your building. It involves identifying areas with excessive moisture that could lead to structural damage, mold growth, and other indoor air quality issues.

Acceptable Moisture Levels

Drywall has an ideal moisture content range between 5% and 15%. When moisture levels exceed this range, the material can become compromised and pose a risk to the integrity of the structure.

What is a Normal Moisture Reading for Drywall?

A normal moisture reading for drywall depends on the environmental conditions. Generally, acceptable values are as follows:

  • 0% – 10%: Dry and healthy
  • 11% – 15%: Slightly moist, but generally acceptable
  • 16% – 20%: Moderate moisture, indicating a potential problem
  • Over 20%: Excessive moisture, requiring immediate attention

It’s important to note that these readings can vary slightly based on the type of drywall used and the specific location. Monitoring moisture levels is essential to ensure the ongoing health of your building.
