If there is a "moldy smell" in a building but no visible mold, should mold be suspected?

A "moldy smell" often indicates the presence of mold, even if it is not visible. Mold can produce volatile organic compounds (VOCs) that create an earthy or musty odor. When occupants notice such smells, it often suggests that mold is either hidden from sight or developing in an area that is not easily accessible, such as inside walls, under carpets, or in other enclosed spaces.

In situations where a moldy odor is detected, it is prudent to investigate further. Factors such as moisture levels, water damage, and past leaks can create an environment conducive to mold growth. Therefore, the presence of a moldy smell should prompt an assessment for mold, including checking for moisture issues and looking in areas where mold typically thrives. Ignoring the smell because there is no visible mold can lead to undetected mold growth, which could pose health risks and structural problems over time. Hence, mold should certainly be suspected when there is a distinct odor associated with it.
