Here is what to do when a pipe bursts: **shut off the water first**, at the main valve where the line enters your cellar or at your apartment's shutoff. Keep away from wiring in standing water, photograph the damage, and start drying right away, since EPA says wet materials dried **within 24–48 hours** usually won't grow mold.

[NYC Repipe & Repair](https://nycrepipe.com/) publishes these figures with named sources so every number can be checked before you call anyone, including us.

A burst pipe in a New York City building keeps pouring water into ceilings and the apartment below until someone finds the valve. How fast you shut it off decides most of the damage, and the next two days decide whether you’re dealing with mold. Here’s the order to work in.

## In the first few minutes

Order matters here, so follow it:

1.  **Shut off the water.** In a house, the main valve is where the service line comes through the cellar or basement wall, next to the meter. Turn it clockwise until it stops. In an apartment, use your unit’s shutoff if you have one; if not, call the super, because the risers are controlled by the building. One [Brooklyn](https://nycrepipe.com/boroughs/brooklyn/) renter’s post describes pipes bursting over a weekend and flooding the whole apartment ([r/Brooklyn](https://www.reddit.com/r/Brooklyn/comments/zw5uv7/apartment_pipes_burst_over_the_weekend_flooding/)). Find your valve now, before you need it.
2.  **Stay clear of electricity.** Don’t walk through standing water near outlets, a panel or appliances. Schneider Electric’s water-damage guidance is not to switch off the main yourself if that means standing in water, and to have an electrician or the utility do it ([Schneider Electric](https://www.se.com/us/en/work/services/water-damaged-electrical-equipment/storm-response-faq)). Equipment that has been under water needs to be checked or replaced before it’s turned back on.
3.  **Drain the lines.** Open the lowest faucet in the building and a top-floor faucet to empty what’s left in the pipes.
4.  **Call a plumber.** Calls are answered 24/7 at the number below, and a [plumber for water leaks](https://nycrepipe.com/plumber-for-water-leaks/) handles the follow-up. [Burst pipe repair](https://nycrepipe.com/burst-pipe-repair/) covers what the emergency visit includes.

## Document everything for insurance

Before you mop or throw anything out, photograph and video the broken pipe, the ceiling and walls, the floor and every damaged item. Insurance guidance is consistent on this: keep damaged belongings until the adjuster has seen them, keep receipts for emergency repairs, fans and dehumidifiers, and report the claim promptly, since some policies set a reporting window ([Insurify](https://insurify.com/homeowners-insurance/knowledge/burst-pipe-insurance-claim-tips)). Temporary repairs to stop the water are expected; hold off on permanent ones until the insurer has assessed the damage.

Homeowners policies generally cover sudden, accidental water damage. They generally don’t cover replacing pipe that simply wore out. [Is repiping covered by insurance?](https://nycrepipe.com/answers/is-repiping-covered-by-insurance/) explains where that line falls.

## Dry it within 24 to 48 hours

EPA’s mold guidance says to dry water-damaged areas and items within 24 to 48 hours; when that happens, in most cases mold won’t grow ([EPA](https://www.epa.gov/mold/brief-guide-mold-moisture-and-your-home)). In practice:

-   Pull up wet rugs and move furniture off wet floors.
-   Run fans and a dehumidifier, and open windows when the outside air is drier.
-   Open ceiling and wall cavities that are holding water. Plaster and lath in prewar buildings holds water longer than drywall, and a sagging ceiling should come down under control rather than by itself.
-   If you can’t find where all the water went, [water leak detection](https://nycrepipe.com/water-leak-detection/) traces it inside walls and floors.

## In a co-op, condo or rental

Tell the super and the managing agent straight away, in writing as well as by phone, and alert the neighbors below. The building usually controls riser shutoffs, and the unit below often has more damage than yours. Who pays depends on where the pipe failed and what your proprietary lease and alteration agreement say; the usual split is that the building owns risers and the shareholder owns branch lines. [Co-op alteration agreement requirements](https://nycrepipe.com/answers/co-op-alteration-agreement-plumbing/) and [who pays for riser replacement](https://nycrepipe.com/answers/who-pays-for-riser-replacement-co-op/) cover the detail. Renters: the landlord repairs the pipe, and your own renters policy covers your belongings.

## The repair, the permit and the price

Emergency work doesn’t wait for paperwork in NYC. A repair that replaces no more than 10 feet of pipe is ordinary plumbing work and needs no permit; the Licensed Master Plumber reports it to DOB monthly on form OP128 ([DOB ordinary plumbing work](https://www.nyc.gov/assets/buildings/pdf/op128-inst.pdf)). For bigger jobs, DOB’s [Emergency Work Notification](https://www.nyc.gov/site/buildings/industry/laa-emergency-notice.page) lets a Licensed Master Plumber do the work first and file the Limited Alteration Application afterward.

NYC price guides put an emergency burst-pipe repair at **$500 to $2,000**, before ceilings or floors are restored ([Handyman NYC price guide](https://handyman-new-york-city.com/guides/cost/pipe-replacement-costs-nyc/)). The repair has to be copper or brass: removable push-fit fittings are prohibited for permanent work (PC 605.9), and new copper meeting old galvanized needs an ASSE 1079 dielectric union (PC 605.24.1). [Pipe repair](https://nycrepipe.com/pipe-repair/) covers the method.

## When a burst means it’s time to repipe

One burst in an otherwise sound system is a repair. A burst in [galvanized pipe](https://nycrepipe.com/galvanized-pipe-replacement/), a second leak, brown water and weak upstairs pressure together mean the system is failing, and the next weak joint will go. Galvanized pipe’s typical working life is 40 to 60 years, and most NYC houses are far older. Read [should I replace galvanized pipes?](https://nycrepipe.com/answers/should-i-replace-galvanized-pipes/), take the [repipe assessment](https://nycrepipe.com/tools/repipe-assessment/), price it with the [repipe cost estimator](https://nycrepipe.com/tools/repipe-cost-estimator/), or see [whole house repiping](https://nycrepipe.com/whole-house-repiping/). If the burst was in copper with small pinholes, [pinhole leaks in copper pipes](https://nycrepipe.com/answers/pinhole-leaks-copper-pipes/) is the better guide.

## Bottom line

Shut the water off, stay clear of wet wiring, photograph everything, and get it dry within 24 to 48 hours. In a building, tell the super and managing agent first. A Licensed Master Plumber can repair it right away under DOB’s emergency rules. Call [(929) 659-6658](tel:+19296596658) any time; calls are answered 24/7, with a same-day callback.

## Quick answers

Can a plumber fix a burst pipe without a permit in NYC?

Often, yes. A short repair, replacing no more than 10 feet of water pipe, counts as ordinary plumbing work, which needs no permit; the Licensed Master Plumber reports it to DOB afterward. Bigger emergency work can start right away under an Emergency Work Notification, with the Limited Alteration Application filed after the work is done.

Does homeowners insurance cover a burst pipe?

Usually the water damage, yes, because policies generally cover sudden and accidental discharge. They generally don't pay to replace pipe that wore out, and they can dispute slow leaks. Photograph everything before cleanup, keep damaged items until the adjuster sees them, and keep every receipt for emergency work and drying.

My apartment flooded from the unit above. What do I do?

Call the super or building staff immediately so they can shut the right riser or the upstairs unit's valve, then tell your managing agent in writing. Photograph your damage and notify your own insurer. Who pays between units and the building usually depends on the proprietary lease, the alteration agreement and where the pipe failed.
