The first hour after a pipe bursts: what to do and what to avoid
The first hour after a pipe bursts decides how big the job gets. Water that runs for another ten minutes gets into more rooms. Water that sits for a day soaks into more material. Almost everything useful you can do happens in the first sixty minutes, and most of it is about stopping, not cleaning.
Minute by minute
| When | Do this | Skip this |
|---|---|---|
| First few minutes | Shut off the water at the main, or at the fixture if you can reach it faster. If the water is spraying, keep clear of electrical outlets and the panel. | Do not reach into spraying water near wiring. Do not stop to move furniture while the water is still running. |
| Next ten minutes | Open a faucet at the lowest point of the house to drain the lines. Turn off the water heater's power or gas if the water supply to it has been shut off. | Do not leave the water heater running with no water coming in. |
| Ten to thirty minutes | Take photos and a short video of the source and every wet area. Pick up small items, electronics and anything that wicks. Open closet and cabinet doors. | Do not use a household vacuum on water. Do not walk through water near the breaker panel. |
| Thirty to sixty minutes | Call your insurer and a water extraction crew. Write down the time you noticed the leak. Keep damaged materials until they are photographed. | Do not throw out wet materials before documenting them. Do not wait for the insurer to approve before calling for help. |
Find the shutoff before you need it
Most houses have a main shutoff where the water line enters, often in the basement near the front wall, in a utility closet or in a crawlspace. There may also be a meter box at the curb with a valve, but that one usually needs a special key and belongs to the utility. Individual fixtures have their own small valves under sinks and behind toilets. Knowing which one controls what is worth ten minutes on a dry day.
If the main valve is stuck or the water will not stop, call the water utility. Tell them it is an emergency and give your address.
Electricity and water
The most dangerous mistake in the first hour is going into a wet area with live electricity. If water is dripping from a light fixture, running down a wall with outlets, or pooling around the breaker panel, treat the area as live. If you can reach the breaker without stepping in water, turn off the circuits for the wet rooms. If you cannot, leave and call your electric utility or an electrician. A flooded basement with a running furnace, water heater or sump pump has a lot of ways to hurt someone.

Call (301) 786-0888What to save and what to leave
Pick up what you can carry safely: electronics, papers, photographs, small rugs, books, the contents of low shelves. Lift furniture legs off wet carpet with blocks or pieces of foil. Leave heavy furniture and anything that requires lifting through water. The crew can move it with the right equipment.
Do not try to dry things with a hair dryer or a heater. Wet carpet and pad dry slowly and mold can start in a day or two, so the work belongs to equipment that can pull moisture out of the air.
Photos and notes your insurer will ask for
- The broken pipe or fixture, from a couple of angles.
- Each room that is wet, wide shots first and then close-ups.
- Damaged items, with a rough list and what they cost.
- The time you found the leak and the time you shut the water off.
- The name of anyone you called and when.
Photographs taken before the cleanup are the ones that matter. Afterward there is nothing to see.
What happens when the crew arrives
We start with the same question as on the phone: is the source stopped? Then moisture readings go on a sketch of the floor, standing water comes out with pumps and extractors, and wet material that cannot be saved is removed. Air movers and dehumidifiers go in after that. Emergency water extraction describes the equipment on the first visit, and water damage restoration describes the work after it. If the pipe froze, the frozen and burst pipe cleanup page has the winter details.
A note on apartments
In an apartment building, water from a burst pipe rarely stays in one unit. Tell the property manager right away, shut off the water to your unit if you can and photograph everything before it is moved. Our page for South Laurel describes how water moves between units in the rental buildings there.
Services for the next hour and day
- Emergency Water Extraction Pumps and extractors for the first visit.
- Frozen & Burst Pipe Cleanup When a freeze caused the break.
- Water Damage Restoration The work that follows extraction.
Local note: see our page for South Laurel. It covers how water moves between units in rental buildings.
