Acceptable Moisture Levels

Moisture mapping is a crucial aspect of building maintenance and restoration. It entails analyzing the moisture content within building structures, such as walls, floors, and ceilings. Acceptable moisture levels vary depending on the material and its intended use. Generally, for interior spaces, a moisture level below 16% is considered acceptable to prevent mold growth and structural damage. For exterior walls, higher moisture levels may be acceptable depending on the climate and construction materials.

How much moisture is OK in walls?

The acceptable moisture content in walls depends on the type of wall construction and the climate. In general, the moisture level should be maintained below 16% to prevent mold growth and structural damage. However, in areas with high humidity or extreme temperature fluctuations, higher moisture levels may be acceptable. For example, exterior walls in humid climates may have moisture levels of up to 20% without compromising the structure’s integrity.

• Drywall: Less than 16%
• Wood framing: Less than 19%
• Concrete: Less than 75%

It is important to note that moisture mapping is a complex process that requires specialized equipment and expertise. Attempting to perform moisture mapping without proper training and equipment can lead to inaccurate results and incorrect conclusions.
