Burst Pipe Flooded Your House: Do This Now

By NorthBriar Editorial Team · Published Aug 12, 2026 · Reviewed per our editorial policy

So a burst pipe flooded your house, and the water is still finding new rooms. Order matters more than speed here; take the five steps from the top.

1. Shut off the water main. It's where the supply line enters the house: basement, crawl space, garage, or utility closet, usually on the wall facing the street, near the meter or water heater. A round gate valve closes clockwise; keep turning until it seats. A lever-style ball valve needs only a quarter turn: it's closed when the handle crosses the pipe at a right angle.
2. Handle electricity before stepping into any water. Kill the breakers for rooms where water is creeping toward outlets, appliances, or the panel itself, and only do this if the path to the breaker box is completely dry. If it isn't, stay out and have your electric utility cut power. No exceptions.
3. Drain the system. Find the lowest tap on the property (a basement sink or an outside spigot) and open it, giving the water still sitting in the lines a harmless way out rather than the break.
4. Shut off the water heater. With the main closed, the tank shouldn't keep heating: switch off its breaker, or turn a gas unit's control to off or pilot.
5. Call a plumber. NorthBriar connects you with licensed, insured local plumbers who handle burst lines: (800) 555-0173. The call is free; you approve all work directly with the pro.

Confirm it's a burst, not a different flood

Thirty seconds of diagnosis changes who you call. Signs the water is from a burst supply pipe:

• Water flowing fast, from one direction, and it's clean: supply water, not sewage.
• The sound of rushing or hissing inside a wall or ceiling.
• Water pressure at faucets suddenly dropped, or the meter dial spins with every fixture off.
• A ceiling bulge, a soaked wall, or water tracking along a joist line below a bathroom or kitchen.

Dirty water backing up from drains means a sewer problem, not a burst line. Shutting the main won't stop it, so stop running any water and say "sewage backup" when you call. Any smell of gas changes the plan entirely: get everyone out right away, then phone 911 and the gas company once you're outside, touching no switches and lighting nothing on the way.

While you wait: save what the water hasn't reached

Burst pipe flooding keeps moving while you stand still, and every minute of drainage you handle now is drying cost you don't pay later.

• Carry electronics, paperwork, rugs, and lighter furniture clear of the spreading water; slide foil squares or wood blocks under the legs of pieces too heavy to relocate.
• Mop, bail, and towel standing water; a kitchen floor flooded by a burst pipe rewards fast work before seams and cabinet toe-kicks swell. A wet/dry vac helps, but only plugged into an outlet in a dry room, on a dry cord path.
• Open interior doors and, weather permitting, get air moving across wet floors.
• In freezing weather, keep the whole house heated. The burst likely started as ice, and the rest of your plumbing is standing in the same cold; our burst pipes hub explains why one burst often signals others.

Document before you clean up. Photograph and video everything: standing water, the burst section if visible, each flooded room and item, plus the meter. Water-damage-and-freezing claims averaged $13,954 and hit about 1 in 60 insured homes yearly in 2018-2022 data from the Insurance Information Institute, and adjusters pay for what you can show, not what you describe. Keep receipts for fans, a vac, or emergency supplies; call your insurer's claim line the same day.

What not to do

• Don't touch the breaker panel while standing in water. Call the utility instead.
• Don't run a household vacuum on wet floors. Wet/dry vacs only, dry outlet only.
• Don't turn the main back on to "check where it's coming from." You'll pay for the second flood too. Let the plumber pressure-test.
• Don't put a space heater or open flame near a wet wall to dry it, and never use a torch on any pipe, frozen or otherwise.
• Don't wait days to dry things out. Flooded drywall and flooring degrade fast, and remediation gets more expensive the longer materials stay wet.

What "24/7 emergency plumber" really means

Straight talk, since we're a publisher and not a dispatcher: 24/7 means the phone gets answered around the clock, not that a van is idling on your street. During a hard freeze, when half the neighborhood has the same emergency, even good shops triage. You can make the wait work for you:

• Ask for a realistic arrival window and what the after-hours rate covers before you commit.
• Say the words that set priority correctly: "supply pipe burst, main is off, house flooded."
• With the main off and the system drained, the damage has stopped growing, so if it's late evening, ask what a next-morning call costs instead. It's often meaningfully cheaper.

Partner plumbers in the NorthBriar network answer 24/7 during freeze season: (800) 555-0173.

What the repair will cost

National 2025 figures from Angi and HomeAdvisor: most burst pipe repairs run $200-$3,000, with the average around $500; labor is roughly 80% of the bill. After-hours calls commonly add a $50-$300 trip fee, and jobs that include water damage or buried lines can reach $5,000. Once a burst pipe flooded your house, in other words, the plumbing is often the smaller half of the bill; drying and restoration are the larger.
