Wood Destroying Organism (WDO) Home Inspection 2025 – 400 Free Practice Questions to Pass the Exam

The primary function of a moisture meter in home inspections is to determine wood moisture content. Moisture meters are specialized tools designed to measure the amount of moisture present in wood and other building materials. This measurement is critical because elevated moisture levels can indicate conditions that favor the growth of wood-destroying organisms, such as termites and fungi.

By accurately identifying the moisture content, inspectors can assess the potential risk for damage caused by these organisms. Typically, a moisture content above 20% suggests a higher likelihood of fungal growth and wood rot, which can compromise the structural integrity of the home.

The other options focus on different aspects of home inspections, such as air quality or insulation assessment, which are not the primary purpose of a moisture meter. These aspects are important in home inspections but require different tools and methodologies to evaluate effectively.
