Moisture mapping is a valuable tool for detecting and preventing moisture damage in buildings. By accurately measuring moisture levels, professionals can identify areas where excessive moisture may be present, allowing for prompt intervention. Acceptable moisture levels vary depending on the material and location of the measurement.

### What Should Moisture Readings Be for Internal Walls?

Moisture readings for internal walls should typically fall **below 15%**. Internal walls are less exposed to external moisture sources and, therefore, should maintain a consistently low moisture content. Readings **above 20%** may indicate moisture penetration or damage.

It is important to note that moisture levels can fluctuate slightly due to environmental factors such as humidity and temperature. However, prolonged exposure to excessive moisture can lead to structural damage, mold growth, and health issues.

Moisture mapping is a reliable and effective method for assessing moisture levels in internal walls. By identifying areas of concern, it enables targeted remediation efforts to prevent further damage and preserve the integrity of the building.
