Frozen pipes are one of the most common causes of water damage in New York winters. The December 2022 blizzard in Buffalo, for example, left many homes with frozen and burst pipes. Here's how to prevent it and what to do if it happens.
Where pipes freeze
Pipes in exterior walls, unheated crawl spaces, garages, attics and kitchen and bathroom cabinets on outside walls are most at risk. Seasonal homes in the Adirondacks, Catskills and on the East End of Long Island are especially vulnerable when they're empty.
How to prevent frozen pipes
Insulate exposed pipes, seal drafts near them, and disconnect and drain garden hoses before winter. During deep cold, keep the heat at a steady temperature, open cabinet doors on exterior walls, and let a faucet drip. If you leave home for an extended period, keep the heat on or have the plumbing drained.
If a pipe freezes
If a faucet only trickles, a pipe may be frozen. Keep the faucet open and warm the pipe with a hair dryer or space heater, never an open flame. If you can't find or reach the frozen section, call a plumber.
If a pipe bursts
Shut off the main water valve immediately, then turn off power to wet areas if it's safe. Photograph the damage and call your insurer. Extraction and drying should start quickly to limit damage and mold. Learn about water damage removal and water damage removal in New York.
