Look for change
The first sign may be a new odor, a slightly lifted baseboard, a soft cabinet floor, condensation where it was not present before, discoloration around a vent, a ceiling shadow, insects gathering near moisture, or indoor humidity that no longer returns to its normal range.
Inspect slowly enough to compare. Open sink cabinets, look behind toilets and appliances where accessible, check HVAC drain areas, scan ceilings below roof valleys and upstairs plumbing, and examine closets and exterior walls where air movement is limited.
Act on moisture quickly
EPA guidance emphasizes controlling moisture and drying wet materials promptly—generally within 24 to 48 hours where possible—to reduce mold growth. That means finding and stopping the source comes before cosmetic cleanup.
- ✓
Photograph the affected area before moving or cleaning anything.
- ✓
Record temperature, humidity, odor, and the apparent extent of moisture.
- ✓
Stop active water when it is safe and authorized.
- ✓
Call the appropriate qualified professional for the source and drying response.
- ✓
Reinspect after the repair to confirm conditions are improving.
Do not diagnose from a photograph
A photograph can document visible growth or staining, but it cannot establish the full cause or extent. When the situation is significant, recurring, or uncertain, use qualified assessment and remediation professionals and follow the insurer's reporting instructions.
