International Compliance Association (ICA) Home Inspector Practice Exam

Intrusive testing in home inspection specifically refers to a method for inspecting hidden areas, which often involves accessing spaces that are not readily visible or easily examined without taking additional measures. This type of testing is essential for uncovering issues that may not be apparent through standard visual inspections, such as the condition of structural components behind walls or under flooring.

By using intrusive testing methods, inspectors can gather more comprehensive data regarding the property’s integrity, potentially identifying problems like moisture intrusion, mold, or structural defects that might otherwise remain hidden. Techniques for intrusive testing can include cutting into walls, removing sections of flooring, or probing into insulated areas to assess issues that could compromise the safety and livability of a home.

The other options do not capture the essence of what intrusive testing entails. For instance, assessing air quality or conducting a visual evaluation is more non-invasive in nature, while standard procedures for checking foundations typically rely on surface evaluations rather than exploring hidden conditions.
