What is considered a primary method for determining moisture levels in a building?

Using moisture meters and hygrometers is a primary method for determining moisture levels in a building because these instruments provide precise and quantifiable measurements of moisture content in both the air and materials within the structure. Moisture meters can assess the moisture levels in walls, floors, and ceilings, while hygrometers measure humidity in the air. This data is crucial for identifying potentially hazardous conditions conducive to mold growth and for developing effective remediation strategies.

Other methods, such as visual inspections or discussions with occupants, can provide useful information but may lack the accuracy and detail necessary for a comprehensive assessment of moisture levels. Visual inspections might reveal visible signs of moisture, such as staining or mold growth, but they do not provide a quantifiable measurement of moisture levels. Similarly, while occupants can share valuable observations about moisture issues, this information is subjective and can vary between individuals. Installing additional drainage systems is an action taken to address moisture problems but does not measure or assess the existing moisture levels. Therefore, utilizing moisture meters and hygrometers is the most reliable and effective approach for evaluating moisture conditions in a building.
