Common property signs
- Visible fuzzy, spotty, or discolored growth on building materials.
- Musty odor that persists after routine cleaning.
- Drywall, trim, or cabinetry that is swollen, stained, or soft after moisture exposure.
- Repeated growth in the same bathroom, closet, attic, or wall area.
- Evidence of a past or current leak near the affected material.
What to do next
Look for an obvious moisture source without tearing into suspect materials. If the issue is persistent, widespread, concealed, or connected to significant water damage, professional help may be appropriate.
