Identify the source of moisture (fix leaks, plumbing issues, roof/wall leaks, condensation problems, drainage issues)
Dry the area thoroughly (use fans and dehumidifiers; keep humidity below 50%)
Remove mold-contaminated porous materials if damaged (carpet, drywall, insulation, ceiling tiles) when they cannot be cleaned fully
Clean hard, non-porous surfaces with detergent and water, then rinse and dry completely
Use an EPA-registered mold cleaner/biocide on appropriate surfaces per label directions
Wear protective gear: N95 or higher respirator, gloves, and eye protection
Ventilate the area during cleanup (open windows/doors if safe to do so)
Contain the work area when possible (close doors, use plastic sheeting to limit spread)
Avoid dry brushing or vacuuming that can aerosolize spores unless using a HEPA-filter vacuum
Bag and seal moldy debris immediately and dispose of according to local rules
Do not mix cleaning chemicals (especially bleach with ammonia or acids)
For small areas (typically up to about 10 sq ft), clean yourself if you can do so safely
For larger infestations, recurring mold, or if you have health risks, hire a licensed mold remediation professional
Seek medical advice if you have symptoms (persistent coughing, wheezing, asthma flare-ups, allergic reactions) or if cleanup worsens symptoms
After remediation, re-check moisture levels and inspect for recurring water intrusion
Maintain long-term prevention (repair gutters/downspouts, improve ventilation in bathrooms/kitchens, use exhaust fans, ensure proper insulation and vapor barriers where needed)
