It's 2 AM. You hear a rushing sound from the kitchen. You walk in and water is spraying from under the sink, pooling on the floor, and starting to seep under the cabinet. Your first instinct is panic — but the next five minutes are critical.
Burst pipes are one of the most common middle-of-the-night emergencies New York City homeowners face, especially in older buildings where pipes can be decades old. The damage compounds fast: water travels quickly through walls, floors, and into neighboring apartments. Knowing exactly what to do — in the right order — can mean the difference between a $500 repair and a $50,000 restoration job.
This guide walks you through every step, from the moment you discover the burst to when the plumber leaves your apartment.
Step 1: Shut Off the Water — Right Now
This is the single most important action you can take in the first 60 seconds. Every second water flows, damage multiplies. There are two places to shut off water in most NYC apartments:
Pro tip: Right now — not at 2 AM — find your main shutoff and make sure every adult in the household knows where it is. Label it with a piece of tape. This five-minute task could save you tens of thousands of dollars.
Step 2: Call an Emergency Plumber Immediately
Once the water is off, call a licensed 24/7 emergency plumber immediately. Do not wait until morning. Here's why: even after the water is off, the damage continues. Water sitting in walls, under flooring, and in subfloor materials will begin causing mold growth within 24–48 hours. The longer you wait, the more expensive the remediation.
When you call, have this information ready:
- Your full address including apartment number and floor
- Where the burst is (kitchen, bathroom, hallway wall, ceiling)
- Whether you've shut the water off and from where
- How much water is visible and where it's spreading
A licensed plumber can typically be at your door within 30 minutes in NYC. While you wait, move to the next steps.

Before you start cleaning anything up, take photos and video of every affected area. This documentation is critical for your homeowner's or renter's insurance claim. Capture:
- The source of the burst (the pipe itself if visible)
- Standing water on floors
- Water staining on walls and ceilings
- Damaged personal property (furniture, electronics, clothing)
- Water that has traveled to adjacent rooms or hallways
If water has leaked into a neighbor's apartment, document that too and notify your building management immediately. In NYC, you can be held liable for water damage to neighboring units.
Step 4: Protect Electrical Safety
Water and electricity are a deadly combination. If water is pooling near electrical outlets, appliances, or has gotten into walls near your electrical panel, do not touch anything. Your next call should be to an emergency electrician — and if you're unsure whether it's safe to enter a flooded room, stay out until a professional assesses it.
If your circuit breaker is accessible without stepping through water, shut off power to the affected areas. But never stand in water while touching electrical panels or switches.
Step 5: Remove Standing Water — Carefully
Once the water is confirmed off and you've established there's no electrical hazard, start removing standing water. Mops, towels, and wet/dry vacuums all work. Every gallon you remove reduces the risk of mold and structural damage.
Move any furniture, rugs, and personal belongings out of the wet area. Lift furniture legs off wet floors using aluminum foil or wood blocks if you can't move it entirely.
Open windows if weather permits to increase air circulation. Turn on fans to begin the drying process — but again, only if you've confirmed there's no electrical hazard.
Step 6: Notify Your Building Management and Super
In NYC's co-ops, condos, and rental buildings, you're generally required to notify building management of plumbing emergencies promptly. In many buildings, the super has access to main shutoffs that go beyond your unit — and they may need to shut down water to an entire riser (vertical pipe stack) to address the burst properly.
Your lease or proprietary lease will specify notification requirements. Failing to notify can affect your insurance coverage and liability.
Step 7: Begin the Water Damage Restoration Process
Once the emergency plumber has fixed the burst, the real restoration work begins. Water doesn't just stay on the surface — it wicks into drywall, insulation, subfloor material, and framing. If these materials aren't dried properly and completely, mold will develop within 48–72 hours.
Professional water damage restoration involves industrial-grade dehumidifiers, air movers, and moisture meters that check inside walls and floors. A professional team will:
- Map the extent of water migration using moisture meters
- Remove damaged drywall and insulation if water has penetrated deeply
- Set up drying equipment and monitor moisture levels daily
- Apply antimicrobial treatments to prevent mold
- Document everything for your insurance claim
Important: Many homeowner and renter insurance policies cover burst pipe damage — but only if you can demonstrate you acted quickly and called a licensed professional. Documenting your response timeline matters.
What Causes Pipes to Burst in NYC Apartments?
New York City's housing stock is old — many buildings have plumbing installed 50, 60, even 100 years ago. The most common causes of burst pipes in NYC include:
- Freezing temperatures. When water inside pipes freezes, it expands and can rupture the pipe. This is especially common in poorly insulated exterior walls, crawl spaces, and basements during January and February cold snaps.
- Corrosion. Old galvanized steel and iron pipes corrode from the inside over decades, weakening the pipe walls until they fail.
- High water pressure. NYC's water pressure can be high, especially in lower floors. Chronically high pressure stresses pipe joints and fittings.
- Physical damage. Renovation work, nails, and accidental impacts can puncture or crack pipes behind walls.
- Tree roots. In townhouses and brownstones with ground-level plumbing, tree roots can infiltrate and crack pipes.
How to Prevent Burst Pipes in NYC
You can't control your building's age, but you can take steps to reduce your risk:
- Keep cabinet doors under sinks open during extreme cold to allow warm air to reach pipes
- Let faucets drip slightly during freeze warnings
- Know where your shutoff valves are and make sure they actually work
- Have a licensed plumber inspect visible pipes annually — especially in older buildings
- Install a water leak detector near major appliances and under sinks ($30–50 at any hardware store)
When to Call for Professional Help
The answer is: immediately. Even a small burst pipe can discharge hundreds of gallons per hour. Waiting until morning adds hours of additional damage. A professional emergency plumber can typically have the burst repaired in 1–3 hours, and water damage restoration professionals can begin the drying process the same night.
