If a pipe bursts, shut off your home’s main water valve immediately to stop the flooding, then call an emergency plumber. New Pro is available 24/7 across West LA to locate and repair burst pipes fast. Turning off the water and, if it’s near electrical, the power is the critical first step before help arrives.
When a pipe bursts, every minute means more water and more damage, so the single most important thing you can do is shut off your home’s main water supply valve. That stops the flow at the source while you wait for help. If the water is anywhere near electrical outlets or your panel, shut off the power to that area as well — safely, from a dry spot.
Burst pipe repair — Burst pipe repair is the emergency location and repair or replacement of a pipe that has ruptured, stopping active water damage and restoring the line — after the water supply is shut off at the main.
Then call an emergency plumber. New Pro answers 24/7, and we’ll talk you through anything else while we’re on the way.

Get a Free QuoteThe homeowners who handle a burst pipe best are the ones who knew where their main shutoff valve was before it happened. In the panic of water spreading across a floor, hunting for a valve you’ve never located costs exactly the minutes you don’t have. Take five minutes on a calm day to find yours — typically where the water line enters the house, near the meter, along an exterior wall, or in the garage — and make sure everyone in the home knows it too.
It’s also worth knowing what your pipes are made of, because material predicts risk. Older Westside homes often still have galvanized steel or aging copper, and galvanized in particular corrodes from the inside until it fails, sometimes without much warning. If your home has original mid-century plumbing and you’ve had leaks before, a burst may be a sign the system is aging out. Because hidden leaks and bursts waste enormous amounts of water, the U.S. EPA’s WaterSense program emphasizes catching them early — and a pipe that’s already burst is the clearest signal to look at the rest.
When we repair a burst, we do it as licensed, insured work you can stand behind at claim time. We operate under a license you can verify with the CSLB (#974600) and pull permits through the Los Angeles Department of Building & Safety where the repair requires it. In an emergency that’s easy to overlook, but documented, permitted work is exactly what protects you with your insurer and at resale.
It depends on the pipe’s age, material, and why it burst.
| Situation | Fix | Why |
|---|---|---|
| Isolated burst, sound pipe | Section repair | Fast, lower cost |
| Corroded / repeat bursts | Repipe that run | Stops the next burst |
| Failing whole system | Plan a repipe | Long-term fix |
However we fix it, you’ll get a clear flat-rate quote — that’s how 24/7 emergency plumbing should work, no surprises.
Cost depends on where the burst is, how accessible it is, and whether a section repair or a repipe makes more sense. A reachable burst is straightforward; one inside a wall or slab takes more work to access. After we locate it, you get one flat-rate price — even in an emergency, there’s no hourly meter running.
Even after hours, we quote a flat rate first — see how our emergency plumbing service handles pricing.

The Bottom Line
A burst pipe is a race against water. Your job is to shut off the main and, if needed, the power; ours is to get there fast and fix it. Shutting off the water is what turns a catastrophe into a manageable repair — so know where your main valve is before you ever need it.
Shut off your home’s main water supply valve immediately. This stops water from continuing to flood the area and is the single most effective thing you can do before help arrives. If the water is near electrical outlets or your electrical panel, also shut off the power to that area from a dry location. Once the water’s off, call an emergency plumber and start moving valuables out of the water’s path.
It’s usually where the main water line enters your home — often near the street in a meter box, along an exterior wall, in a garage, or in a basement or crawlspace. It’s worth locating yours now, before an emergency, and making sure everyone in the household knows where it is and how to turn it, clockwise to close. In a burst-pipe situation, those few seconds of knowing exactly where to go make a real difference.
Often it can be repaired if the burst is isolated and the surrounding pipe is still sound. We cut out and replace the failed section and restore the line. If the pipe is old, corroded throughout, or has burst before, replacing that run — or planning a repipe — is the smarter long-term fix, because a patch on a failing pipe just buys time until the next burst. We’ll assess it and give you the honest option.
Common causes include corrosion in older pipes that thins the wall until it fails, excessive water pressure, physical damage, and failed joints or fittings. In colder climates freezing is a major cause, though that’s rarer on the Westside. Old galvanized steel piping is especially prone to bursting as it corrodes from the inside. A burst often signals that the pipe — or the wider system — has reached the end of its reliable life.
Many homeowner policies cover sudden, accidental water damage from a burst pipe, though coverage varies and gradual leaks are often treated differently. We can’t speak for your insurer, but we help by documenting the damage and providing a clear, written scope and flat-rate invoice — exactly what a claim needs. Take photos before cleanup begins, and check your specific policy on what’s covered.
