Emergency Water Cleanup Checklist: First 24 Hours

Updated October 17, 2026. Emergency water cleanup in the first hour is three shutoffs and a phone call, in that order when the building is unsafe: gas if you smell it, power if you can reach the breaker from a dry place, and the main water valve if pipes are broken or water is still coming in. The insurance call happens the same hour. It does not replace the shutoffs.

How long the rest of the job takes, from drying through rebuild, is on how long property restoration takes. This page stays on the first 24 hours.

First hour: water, breaker, and gas

Do these only when you can do them without stepping into water or staying in a building that smells like gas.

1. Gas, if you smell it or hear hissing. Get everyone out. Open a window on the way if you can. Shut the outside gas valve only if you can do it without delaying the exit, and call the gas company from outside. Ready.gov, updated March 20, 2026, and CDC's flooded-home guidance, updated August 24, 2026, agree on that sequence. Ready.gov adds that only a qualified professional turns the gas back on. As of October 17, 2026.
2. Breaker, if water is near electricity. Turn the main power off from a dry location, even if that delays mopping. If you would have to stand in water to reach the panel, stop and call an electrician. Do not flip a breaker, and do not run an electric tool, while you are standing in water. CDC's flooded-home page and the American Red Cross utilities guidance both say this. As of October 17, 2026. Have an electrician check the system before power goes back on (CDC).
3. Water, if pipes are damaged or water is still running. Shut the main house valve, the one where the supply line enters the house. Red Cross says to turn the water off at the main valve when pipes are damaged and to call a plumber. Ready.gov says every household should know that valve, and that cracked lines are a reason to shut the water off. The curb box in the sidewalk is the utility's valve and needs a special tool. As of October 17, 2026.
4. Sewage, if you suspect a broken drain line. Do not use sinks, showers, or toilets. Red Cross says to avoid those fixtures and call a plumber when sewage lines may be damaged. Floodwater itself may contain sewage; CDC's flooded-home page says a flooded home may be contaminated with sewage. As of October 17, 2026.

If the ceiling is sagging or a wall is newly cracked, stay out until a building inspector or another qualified person says the structure is safe. CDC's flooded-home page says not to reenter a damaged home until it has been examined.

Insurance first vs restoration first

Use this box once the shutoffs above are done, or ruled out because you cannot reach them safely.

The two Florida sources behind the box, both read October 17, 2026:

• Florida DFS disaster FAQ: you are required by the insurance contract to make temporary repairs to prevent further damage. Take pictures. Keep receipts. Do not dispose of damaged property until the company has completed an inspection. The adjuster must see the damage to evaluate the loss.
• Florida CFO homeowners toolkit: make reasonable emergency repairs whether the cause is a hurricane or anything else, photograph damaged property, save receipts, and do not throw away damaged personal property until the adjuster instructs you to. The insurer has a right to inspect before you are paid.

The Homeowner Claims Bill of Rights says to contact the insurer before you sign a repair contract, and to make and document emergency repairs that are necessary to prevent further damage. Policies are not identical. DFS says its answers follow common forms and that your own policy controls. Nothing on this page is a coverage promise.

Notice also has a statutory outer limit. Section 627.70132 (2026), matching Online Sunshine, bars a property claim or reopened claim unless notice reaches the insurer within 1 year after the date of loss, and bars a supplemental claim after 18 months. For hurricane, tornado, windstorm, or severe rain, the date of loss is landfall or the date NOAA verifies the event. Your policy may require notice sooner. What to photograph and list is on the water damage documentation checklist and the proof of loss timeline.

The rest of the first 24 hours

After the shutoffs and the notice call:

• Extract standing water only with power that is safe. CDC says a wet/dry vacuum or pump is appropriate once an electrician has cleared the power, and to wear rubber boots. If power is not safe, do not run corded tools in the water.
• Dry within 24–48 hours. EPA and CDC both treat that window as the point where mold usually does not get started, as of October 17, 2026. Open windows when the weather is dry enough to help. Use fans and a dehumidifier only when electricity is safe. CDC says not to aim fans so they blow mold through the house, and not to use fans once mold is already growing.
• Clean what you can dry. CDC's disaster cleanup page says to clean wet items and surfaces with hot water and laundry or dish detergent, then dry them. The CDC mold-cleanup guide says to clean with water and a detergent and to dry right away, and not to mix bleach with ammonia. As of October 17, 2026. A bleach ratio is not repeated here.
• Lift furniture off wet flooring and empty drawers so air can move. Leave demolition of drywall and floors for a documented scope. Pulling finishes out before photos exist is the step Florida DFS tells you to avoid.
• Keep a short log: time the water was found, time the valve and breaker were shut, who you called at the insurer, and what you spent on temporary drying. That log feeds the proof-of-loss file.

Daily moisture readings, once a crew is on site, are explained in drying logs and moisture readings. The timeline from mitigation days to rebuild weeks is on how long property restoration takes.

Who to call for the truck

Same-night extraction and drying for a home is emergency restoration. A store, office, or other business is commercial emergency restoration. Ongoing structural drying and repairs sit under water damage restoration. If the water came in through a storm opening, start with storm damage restoration for the temporary protection, then return here for the indoor cleanup steps.

Total Care Restoration's 24/7 line is (305) 428-2192.
