Emergency water damage cleanup: what to do first

Safety comes before removing water. If water is near outlets, electrical equipment or a breaker panel, stay out. For immediate danger, call 911. After a flood or evacuation, return only when local authorities say it is safe.

This guide covers first decisions after a household leak or flood, not instructions for entering an unsafe building or treating contaminated materials yourself.

1. Decide whether it is safe to enter

Look for structural damage from a safe location. Do not enter standing water to reach a breaker. Do not use electrical appliances or tools while standing in water. Wet electrical equipment needs inspection by a qualified electrician before power is restored.

Floodwater may contain sewage, chemicals and other hazards. Avoid contact with it; a clear appearance does not establish that water is safe.

2. Match the next call to the cause

• A leaking supply pipe or appliance: if a shutoff is safely reachable from dry ground, turn off the water. Contact a plumber to address the source; drying alone will not fix a continuing leak.
• Water near electricity: stay clear and contact the utility or a qualified electrician for safe power isolation.
• Flooding, sewage or unknown contamination: follow local officials' instructions and seek professional cleanup assessment. Do not treat it as an ordinary clean-water spill.
• Water inside walls, flooring or ceilings: a restoration provider can assess wet materials and the scope of drying. A dry-looking surface is not proof that hidden spaces are dry.

3. Document damage without taking risks

When safe, take photos and videos before cleanup. Label them by room, record damaged appliance details and keep receipts for cleanup and repairs. Contact your insurer about your policy and documentation requirements; this guide does not establish coverage or payment.

FEMA advises not delaying health-protective cleanup while waiting for an inspection. Avoid moving hazardous items merely to photograph them.

4. Plan drying promptly, but not at the expense of safety

EPA advises cleaning and drying wet materials within 24-48 hours, if possible, to limit mold growth. This is a prevention target, not a promised completion time or a guarantee that mold will not occur.

Which materials can be saved depends on contamination, how long they were wet and their condition. Do not run fans or drying equipment until electrical conditions are safe. For sewage, suspected mold or extensive damage, ask a professional about safe removal and drying rather than starting a DIY cleanup.

5. Ask questions before agreeing to work

• What must be repaired to stop the water source?
• How will you check moisture in hidden spaces and confirm drying?
• Which materials need removal, and why?
• What is included in the written estimate, and what could change it?
