What to do in the first 24 hours after water damage
In the first 24 hours after water damage: make sure everyone is safe, stop the water source, switch off power to wet areas, photograph the damage, remove valuables, and call a restoration company and your insurer. The EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold. Use this water damage checklist for what to do after water damage, in order.
1. Put safety first
Do not walk through standing water if electrical outlets, appliances or cords may be energized. If you can reach the electrical panel safely and dry, turn off power to the affected area. If water has touched wiring, call an electrician. If anyone is in danger, call 911. If the water might be sewage or floodwater, keep children and pets away; see water damage categories.
2. Stop the source
For a plumbing leak, shut off the main water valve. For a roof leak, contain the water with buckets or a tarp if it is safe, and do not climb on a wet roof. California’s Department of Insurance advises homeowners to immediately try to find and stop leaks at the source.
3. Document everything before you clean
Take photos and video of the damage, the source and affected belongings. Note the date and time you discovered it. This record supports an insurance claim. Do not discard damaged items until your insurer agrees, unless they are hazardous.
4. Call your insurer and a restoration company
Report the loss promptly. The Department of Insurance recommends reporting water damage claims right away. Then call a restoration company for extraction and drying. Ask whether they are licensed, as discussed in how to choose a restoration company.
5. Start safe, simple drying
Remove standing water if it is small and clean, lift wet small rugs, open closet doors and cabinets, and promote air circulation. Do not use a household vacuum on water, and avoid heating the house in ways that trap humidity. Larger losses need professional extraction and drying.
6. Know the clock
The EPA’s guidance is to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. See mold after water damage for what to watch for beyond that window.
