👃 A musty smell is trying to tell you something.
You know that smell — you walk into a room and something just smells… off.
Even when you don’t see anything unusual, a persistent musty odor can be a clue that excess moisture is hiding somewhere it shouldn’t be.
Behind walls. Under flooring. Around an AC system. Or in another area you may not be able to see.
Does a musty smell automatically mean mold? No. But covering it up with air fresheners doesn’t tell you what’s causing it either.
The goal is to figure out why it’s there.
Moisture readings, a visual inspection, and when appropriate, mold or indoor air quality testing can help give you answers instead of guesses.
