Musty odors usually indicate MVOCs (Microbial Volatile Organic Compounds). These are gases released by actively growing mold. Even if you don't see mold, the smell is a strong indicator of a moisture problem hidden behind walls or under floors.

Ignoring musty smells can lead to increased respiratory issues, allergic reactions, and significant property damage over time.
