How to prevent mold after a water leak

Fix the source of moisture, arrange prompt drying, and ask a qualified professional how affected materials should be assessed.

What you'll learn

  • EPA recommends drying water-damaged areas and items within 24 to 48 hours where possible.
  • Ask how the professional will assess and monitor wet materials
  • Why a dry-looking surface may hide moisture behind it
  • How the water source and material affect removal or drying decisions

Step by step

  1. Stop additional water only when the shutoff is safe to reach.
  2. Have the source repaired and identify affected adjoining spaces.
  3. Ask how wet materials and cavities will be checked.
  4. Avoid disturbing visible mold while planning cleanup.
  5. Ask how drying will be monitored and whether removal is needed.
Safety note

A dry-looking surface does not establish the condition behind it. Ask how concealed areas will be assessed.
