Question: 1 / 400

How can a home or building be tested for hidden mold?

Through visual inspection only

By measuring humidity levels

Using invasive inspection methods like core sampling

Testing a home or building for hidden mold often requires invasive inspection methods like core sampling. This technique involves taking samples from walls, ceilings, or other surfaces to identify the presence of mold that may not be visible on the surface. Core sampling is particularly effective for detecting mold growth in areas that are concealed, such as within insulation, behind drywall, or beneath flooring.

In contrast, while visual inspections and assessing humidity levels can provide useful information about potential mold issues, they might not accurately indicate the presence of hidden mold behind surfaces. Air fresheners do not play any role in detecting mold and are ineffective for testing purposes. Thus, core sampling is a critical approach when trying to uncover mold that is not immediately apparent, making it the most reliable method among the options provided.
