Moisture Mapping is a comprehensive assessment to accurately identify moisture intrusion and its extent within a building, or its components. It is the process of locating, measuring, and analyzing areas of excessive moisture in a home or commercial building. Using advanced technology, Moisture Mapping helps determine the severity of the moisture problem, its possible source or sources, and charts the extent of the moisture incursion. It then also helps in moisture mitigation. Moisture Mapping ensures that areas of moisture are appropriately addressed, the structure is dried correctly, and the spread of the moisture is contained. ### What is an Acceptable Moisture Level in Wood Framing? In wood framing, moisture intrusion can deteriorate the wood, leading to structural damage and a compromised indoor environment. However, the acceptable moisture level for wood framing varies depending on the wood species, age, environmental conditions, and intended use. The generally accepted moisture levels for wood framing are as follows: - **New lumber:** Less than 19% - **Existing lumber:** Less than 15% Wood framing with moisture levels exceeding these limits will more likely be subject to decay, mold growth, and structural issues. Excessive moisture leads to a reduction in wood's load-bearing capacity. The presence of mold and other fungi can lead to health problems in a building's occupants and reduce the lifespan of the framing materials.
