What Can Be Mistaken for Mold Smell?
A musty smell doesn’t always mean visible mold, but it should never be ignored. Odors from damp carpet, bacteria, HVAC dust, sewer gas, pests, VOCs, wet building materials, or old water damage can all be mistaken for mold smell. In this guide, Spotless explains what may be causing that odor, why moisture is usually the first clue, and when a professional mold inspection makes sense. You’ll also learn how Caleb Jones, Lead Inspector at Spotless, uses tools like moisture meters, air testing, and on-site air quality equipment to separate mold concerns from other indoor air problems.
