What Does Black Mold Smell Like? Musty Odors Explained
Black mold often has a musty, damp, earthy smell, but odor alone can’t tell you what type of mold is present or how serious the problem is. A mold smell may come from hidden moisture behind walls, crawl spaces, attics, HVAC systems, flooring, or old water damage. In this guide, Spotless explains what black mold may smell like, why musty odors should be investigated, what else can mimic mold smell, and when a professional mold inspection makes sense. You’ll also learn how Caleb Jones, Lead Inspector at Spotless, tracks odor clues back to hidden mold sources.
