Identifying musty odors in Memphis homes
Musty smells signal active mold growth even when you can’t see it. Memphis’s clay-rich soil can amplify these odors through foundation cracks. The smell often intensifies during HVAC operation as air circulation spreads spores throughout the home.

- Earthy scent from Stachybotrys in wall cavities
- Sweet heavy odor from Aspergillus in attics
