Moisture mapping is a valuable tool for evaluating and controlling moisture within a structure. By analyzing moisture levels in various building components, it becomes possible to identify potential issues and implement preventative measures.

### Acceptable Moisture Levels

Maintaining appropriate moisture levels is crucial for the long-term integrity and health of a building. These levels vary depending on the material and its location within the structure. Generally, acceptable moisture levels fall within the following ranges:

– **Wood:** 4-12%
– **Concrete:** 75-95% RH
– **Insulation:** 20-30% RH

### What is a Bad Moisture Reading?

Moisture levels exceeding the acceptable range can indicate potential problems. Elevated moisture levels can contribute to:

– **Mold growth:** Moisture provides a favorable environment for mold spores to thrive.
– **Wood decay:** Excessive moisture can lead to wood rot and structural damage.
– **Corrosion:** Moisture can corrode metal components within the building.
– **Health hazards:** Mold growth can release harmful spores into the air, posing health risks to occupants.

It is important to note that moisture readings may vary depending on the timing and location of the measurement. Therefore, it is recommended to consult with a qualified professional to interpret moisture readings and determine if further investigation or remediation is necessary.
