Water Damage Emergency: What to Do First

Updated October 22, 2026 · General information from Water Damage Restoration Cost

If water is rising, if you smell gas, or if water is near live electrical equipment, leave the area and call 911 or your utility.

1. Safety

• Stay out of standing water that may be in contact with outlets, appliances, or the electrical panel.
• Shut off power to affected areas only if you can reach the panel from a dry location. Otherwise call an electrician or your utility.
• Watch for sagging ceilings, and keep people away from them.
• Assume flood water and sewage are contaminated. Wear boots and gloves.

2. Stop the water

• For plumbing leaks, shut off the main water valve or the fixture's shutoff.
• For roof leaks, contain the water with buckets and tarps; don't climb on a wet roof during a storm.
• For appliance leaks, turn off the appliance's water supply.

3. Document

Take photos and video of everything before you move anything: the source, standing water, water lines on walls, and damaged belongings. Keep the failed part.

4. Call your insurer

Report the loss, get a claim number, and ask what they need from you. See how claims usually work.

5. Start drying

• Remove standing water with a wet vac, mops, and towels.
• Move furniture, rugs, and belongings out of wet areas. Put aluminum foil or blocks under furniture legs on wet carpet.
• Open cabinet doors and drawers.
• Run fans and a dehumidifier. Keep windows closed if outside air is humid.
• Call a restoration company for anything beyond a small clean-water spill.

6. What not to do

• Don't use a household vacuum on water.
• Don't turn on ceiling fans or lights if the ceiling is wet.
• Don't throw away damaged items before they're documented, unless they're a health hazard (photograph them first).
• Don't sign contracts or assignment-of-benefits forms you haven't read.

Why speed matters

Clean water can become contaminated as it sits, and the EPA advises drying water-damaged areas within 24 to 48 hours to help prevent mold. Faster drying generally means less tear-out and a smaller bill.

Frequently asked questions

What is the first thing to do after water damage?

Make sure everyone is safe, then stop the water by shutting off the main valve or the fixture's supply.

Should I call my insurance company right away?

Yes, report the loss promptly. Policies generally require prompt notice and reasonable steps to prevent further damage.

Can I stay in my home after water damage?

Often yes for small losses. Large losses, sewage, or no water or power may make the home unlivable. Some policies cover additional living expenses after a covered loss.

How soon should drying start?

As soon as possible. EPA guidance is to dry water-damaged areas within 24 to 48 hours to help prevent mold.
