What is a common tool used by building inspectors during an inspection?

A moisture meter is an essential tool for building inspectors as it allows them to measure the moisture content in materials such as wood, drywall, and concrete. This capability is particularly important because elevated moisture levels can indicate water intrusion, past leaks, or conditions conducive to mold growth, which are critical factors in assessing the health and safety of a building. Spotting moisture issues early can prevent further damage and costly repairs down the line, making the moisture meter a valuable instrument during inspections.

While a calculator might be useful for performing basic calculations, and a digital camera can assist with documentation, these tools do not directly assess the condition of building materials. A screwdriver may be used to access parts of the building, such as opening up panels or receptacles, but it does not provide the specific measurements that a moisture meter offers. Thus, the moisture meter stands out as a vital tool for evaluating the condition and integrity of a building during inspections.
