Snow, Freezing Temps & Burst Pipes in New York: A Winter Water Damage Guide

Burst pipes in New York are one of the most common and costly winter emergencies for homeowners, landlords, co-op boards and businesses. When temperatures fall into the teens, water inside exposed pipes freezes, expands and builds pressure until a pipe splits. Often nobody notices until the thaw, when hundreds of gallons pour into walls, ceilings and basements. All Dry USA provides 24/7 emergency water damage response across New York City, Long Island, Westchester, Rockland and the Hudson Valley. Call 1-888-998-2379.

Why New York Winters Are So Hard on Plumbing

New York’s housing stock is old. Pre-war apartment buildings, brownstones, Long Island capes and Hudson Valley farmhouses often have plumbing running through uninsulated exterior walls, crawl spaces and unheated basements. Add a nor’easter, a polar vortex cold snap or a week of single-digit nights, and the weak points show up fast:

• Pipes in exterior walls and under sinks on outside walls, especially kitchens and bathrooms on the north side of the house
• Attics, crawl spaces and garages with little or no heat
• Vacant units, vacation homes and empty offices where the heat was turned down or failed
• Outdoor spigots and sprinkler lines that were never shut off and drained
• Fire sprinkler branch lines in commercial and multifamily buildings, which can release large volumes of water when they freeze and crack

A pipe usually doesn’t burst where the ice forms. Pressure builds between the ice blockage and a closed faucet, and the pipe splits there, sometimes inside a wall several feet away from the frozen spot. That’s why the damage is often hidden until water shows up through a ceiling.

Snow and Ice Cause Water Damage Too

Burst pipes aren’t the only winter threat. Heavy snow brings its own kinds of water damage:

• Ice dams: Heat escaping through the attic melts snow on the roof, and the water refreezes at the colder eaves. Meltwater backs up under the shingles and leaks into ceilings and exterior walls.
• Snowmelt flooding: Fast thaws and rain on top of snowpack overwhelm drains and push water into basements and through foundation cracks.
• Roof load: Wet, heavy snow on flat roofs, common on New York City rowhouses, garages and commercial buildings, can strain the roof and clog drains, leading to leaks and, in extreme cases, structural damage.

How to Prevent Frozen Pipes This Winter

1. Keep the heat on. Keep the thermostat at 55°F or higher, even when you travel. In New York City, owners must keep apartments at least 68°F during the day when it’s below 55°F outside and 62°F overnight from October 1 through May 31 (NYC HPD heat rules).
2. Open cabinet doors under kitchen and bathroom sinks on outside walls so warm air reaches the pipes.
3. Let faucets drip on the coldest nights. Moving water is much harder to freeze, and an open tap relieves pressure.
4. Insulate exposed pipes in basements, crawl spaces, attics and garages with foam sleeves or heat tape rated for the job.
5. Shut off and drain outdoor spigots and disconnect garden hoses before the first hard freeze.
6. Seal drafts around rim joists, dryer vents and pipe penetrations.
7. Know where your main shutoff is and make sure it turns. Seconds count once a pipe bursts.

What to Do If a Pipe Freezes or Bursts

If a pipe is frozen (no water, or just a trickle)

• Open the faucet so water can flow as the ice melts.
• Warm the pipe with a hair dryer, space heater kept at a safe distance, or warm towels. Start near the faucet and work back.
• Never use an open flame or torch. It’s a serious fire risk, especially inside walls.
• If you can’t find or reach the frozen section, call a plumber.

If a pipe has burst

1. Shut off the main water valve immediately.
2. Turn off electricity to affected areas if water is near outlets, fixtures or the panel, and only if you can reach the breaker safely.
3. Photograph and video everything before you move anything. Your insurance adjuster will want it.
4. Move valuables, electronics and documents out of the wet area.
5. Call your insurance company and a professional water damage restoration company. Your policy expects you to take reasonable steps to prevent further damage.
6. In an apartment, co-op or condo, notify the super or managing agent right away. Water travels to the units below.

Frequently Asked Questions

At what temperature do pipes freeze in New York?

Pipes in unheated or exterior spaces are at risk once outdoor temperatures drop to about 20°F, especially overnight or during multi-day cold snaps. Pipes in attics, crawl spaces, garages and outside walls freeze first.

Does homeowners insurance cover burst pipes?

Most New York homeowners and condo policies cover sudden water damage from a burst pipe. Claims can be denied if the home was left unheated or the damage built up slowly, so document everything and call your carrier quickly.

Who is responsible for a burst pipe in a New York City co-op or condo?

It depends on where the pipe failed and your proprietary lease or bylaws. Pipes inside your unit’s walls are often the building’s responsibility, while fixtures and finishes are often the owner’s. We document the source so both the board and the owner’s insurer have what they need.

How fast does mold grow after a burst pipe?

Mold can begin growing on wet drywall, carpet pad and wood within 24 to 48 hours. Professional extraction and structural drying in that window is the best way to prevent it.
