Risk factors
- porous material stayed wet
- insulation or carpet pad was missed
- humidity remained high
- the source continued slowly
Homeowner guide
Moisture, material, airflow, humidity, and hidden cavities all affect mold risk.

A clock alone does not determine the outcome. Material type, temperature, humidity, airflow, contamination, hidden cavities, and whether the moisture source continues all affect drying and mold risk.
Save photographs, source-repair notes, authorizations, estimates, readings, equipment dates, receipts, invoices, and written completion evidence in date order. Keep mitigation, contents, and reconstruction records separate.
