**Moisture mapping** is a non-destructive testing technique used to determine the moisture content of wood framing. It involves using a moisture meter to measure the electrical resistance of the wood, which is inversely proportional to its moisture content. ### What is an Acceptable Moisture Level in Wood Framing? The acceptable moisture level in wood framing depends on the intended use of the structure. Generally, moisture levels below 19% are considered acceptable for most applications. Wood with moisture levels above 19% is more susceptible to decay, mold growth, and structural damage. **Factors that Affect Moisture Levels in Wood Framing:** * Climate * Exposure to moisture * Ventilation * Construction practices **Consequences of Excessive Moisture in Wood Framing:** * Decay and rot * Mold growth * Structural damage * Increased energy consumption **Benefits of Moisture Mapping:** * Identifies areas of high moisture content * Facilitates targeted remediation efforts * Prevents costly repairs and potential health hazards * Ensures the durability and longevity of the structure
