Water damage: what to do in the first hour

1. Safety first

• If water is near outlets, appliances or your electrical panel, don't walk through it. Shut off power at the breaker only if you can reach it safely and dry; otherwise call your utility or an electrician.
• If you smell gas, leave and call 911 or your gas utility from outside.
• Sewage or floodwater can carry bacteria — avoid contact and keep kids and pets away.

2. Stop the source

Find your main water shut-off valve (often near the water heater, in a basement, garage, or where the line enters the house) and turn it off. For an appliance leak, close the appliance's supply valve.

3. Document before you clean

Take photos and video of the water, the source, and damaged belongings before moving things. Note the time you discovered the leak. This helps with any insurance claim.

4. Protect what you can

• Move furniture, electronics and valuables to a dry area.
• Place foil or wood blocks under furniture legs that can't be moved.
• Lift rugs and curtains off wet floors.

5. Call your insurer and a restoration pro

Most policies expect you to take reasonable steps to prevent further damage. Professional water mitigation — extraction, dehumidifiers and air movers — typically needs to start quickly to reduce the risk of mold. Ask any provider about certifications, insurance and how they work with your insurer.
