Frozen Pipes in New York Winters: Prevention and Damage
New York winters are long and cold, and frozen pipes are one of the most common winter water problems in the state. A pipe does not have to be old or damaged to freeze; it only has to be exposed to cold air for long enough, and when the water inside it freezes, it expands and can split the pipe.

This guide explains how frozen pipes happen, what prevention looks like in general terms, and what to do when a pipe freezes or bursts. No prevention step can promise a pipe will not burst.
Winter freeze in general terms
Pipes freeze when the water inside them drops below freezing and turns to ice. The ice expands, and the pressure it creates can split the pipe wall, often at a joint or a bend. The burst may not show itself until the ice thaws and water starts to escape.
Pipes in unheated spaces are the most exposed: basements, garages, crawl spaces and pipes running along outside walls. Older homes with aging plumbing can be more exposed, but any home can have a frozen pipe in a cold snap.
Prevention in general terms
Prevention in general terms means keeping pipes warm and water moving: insulating exposed pipes, sealing drafts in unheated spaces, keeping the heating on during cold weather, and letting taps drip slightly during a freeze in some cases. These steps reduce the risk, but no promise can be given that prevention stops a burst.
Before winter, it is worth finding your main shut-off valve and checking that it turns, so you can stop the water quickly if a pipe does burst. Knowing where it is before an emergency is one of the simplest preparations you can make.
What a frozen pipe may point to
A frozen pipe may point to a cold spot in the house, a gap in insulation, or a pipe that runs through an unheated space. If the same pipe freezes more than once, the underlying cause is worth finding rather than just thawing the pipe each time.
Never use an open flame or a torch on a frozen pipe. If a pipe is frozen and you cannot thaw it safely, call a professional rather than trying to force it. Our page on burst pipe water damage repair explains what happens if a frozen pipe does burst.
When to call
Call a professional if a pipe has burst, if water is leaking, if you cannot find the source of a leak, or if a frozen pipe will not thaw safely. Do not wait for the thaw to see what happens, since the water can spread quickly once the ice melts.
In the west of the state, frozen pipe help in Buffalo follows the same first steps, and emergency water removal covers getting the water out once a burst is found. Take photos of the damage for your records.
