The 10-Minute Mold Walk-Through
A free, room-by-room checklist to spot moisture, musty odors, and signs of hidden mold in 10 minutes

Mold grows where you can't see it: behind walls, under carpet, inside HVAC systems. So go looking. Grab a flashlight and trust your nose.
This cheat sheet takes you room by room. Tick each spot once you've looked, and circle anything wet, stained, or musty. If you find something, remember the rule I come back to: mold control is moisture control. Find the moisture source first. And keep inspection independent. The person who tells you whether you have a problem should not be the person paid to remediate it.
When you're done, the full guide, Is It Allergies… or Is It Mold?, helps you understand what you found.
