What To Do in the First 24 Hours After Water Damage

Published January 15, 2026

The first 24 hours after discovering water damage matter more than any other stretch of the restoration timeline. What you do — and how quickly you act — has a real effect on how much of your property can be saved. Here's a practical walkthrough of what to do, roughly in order.

1. Stop the Source, If You Can Do It Safely

If the water is coming from a identifiable source — a supply line, a washing machine hose, a water heater — shutting off that source is the first priority. Most homes have a main water shutoff valve; knowing its location before an emergency happens is worth five minutes of your time. If you can't identify or reach the source safely, don't force it — wait for a professional.

2. Address Electrical Safety

Standing water near outlets, switches, or appliances is a real hazard. If you can reach your breaker panel without walking through water, shutting off power to the affected area is a reasonable precaution. If reaching the panel means walking through standing water, don't — leave it and let a professional assess it.

3. Document What You're Seeing

Before you move anything, take photos and a short video of the affected areas. This documentation is useful both for your own reference and for any insurance claim you may file. Note the approximate time you discovered the damage, too.

4. Protect What You Can, Safely

If it's safe to access the area, move electronics, important documents, photos, and other valuables away from standing water or areas likely to get wet. Don't put yourself at risk to save belongings — everything in this step is secondary to your safety.

5. Call a Restoration Professional

This is the step that actually limits how much damage occurs. The sooner professional water extraction and drying begins, the less time water has to spread into flooring, drywall, and framing. If you're in the San Diego area, Agee Restoration Services answers emergency calls 24/7 at 619-399-0516.

6. Avoid DIY Drying Shortcuts for Anything Beyond a Small Spill

Household fans and a shop vac can help with a small, contained spill, but they're not a substitute for professional extraction and drying equipment on a larger loss. Surface-drying an area while moisture remains trapped underneath or behind materials can mask a problem rather than solve it — and create conditions for mold growth.

7. Start the Insurance Conversation

Depending on the cause of loss, your homeowners' or commercial policy may cover some or all of the damage. Contact your insurance provider to start the process, and keep the photos and notes from step 3 on hand — they'll likely be useful.

What Happens Next

Once a restoration company is on site, the process typically moves into inspection, extraction, and drying. You can read a full breakdown of what to expect on our water damage restoration page.
