First 15 Minutes: Stop the Source

Safety first: if water is near electrical outlets, do not enter. If safe, locate and turn off the water source or main shut-off valve. Move to a dry area and call a water damage restoration professional immediately.

First Hour: Document and Mitigate

Take photos and videos of all damage before touching anything. Move valuable items from wet areas if safe. Place aluminum foil under furniture legs to prevent staining. Open windows for ventilation if weather permits.

First 24 Hours: Professional Response

Water damage professionals should begin extraction within hours. Contact your insurance company to report the loss. Follow up documentation with a detailed list of damaged items. Photograph damage before disposal and ask your insurer about retaining safe material samples. Do not keep items that pose a health hazard merely to wait for an adjuster.

What NOT to Do

Do not use a regular vacuum on water (electrocution risk). Do not use electrical appliances in wet areas. Do not enter rooms with sagging ceilings. Do not attempt to remove black water yourself. Do not delay calling professionals - every hour matters.

Frequently Asked Questions

Should I call my insurance company or a restoration company first?

Stop the water, then call a restoration professional, then your insurer — in that order. Your policy requires prompt mitigation, and emergency extraction can't wait for an adjuster. Document everything before cleanup starts so the claim isn't weakened by the fast response.

Is it safe to stay in my house after water damage?

For minor clean-water damage away from electrical systems, usually yes. Leave if water contacted wiring or outlets, ceilings are sagging, sewage is involved, or the water source is unknown. When in doubt, stay out of affected rooms until a professional assessment.

How fast does water damage get worse?

By the hour. Drywall wicks water upward continuously, wood begins absorbing immediately, and mold can start colonizing within 24-48 hours. Damage that costs hundreds to dry on day one can cost thousands by day three — which is why every step in this guide starts with 'immediately.'
