Syracuse winters are among the harshest in the northeastern United States. When temperatures plunge below zero, the risk of frozen and burst pipes rises dramatically. Here's what every homeowner needs to know.
Syracuse, NY consistently ranks among the snowiest cities in the United States, with average annual snowfall exceeding 120 inches. But it is not the snow that bursts pipes — it is the temperature. When the mercury drops below 20°F, water inside uninsulated pipes begins to freeze and expand, creating pressure that can split copper, PEX, or galvanized steel pipe in seconds.
The most vulnerable areas in a typical Syracuse home are pipes running through exterior walls, pipes in unheated crawl spaces or garages, and supply lines near windows or doors where drafts are common. Older homes built before the 1970s are at particular risk because they were often constructed before modern insulation standards.
Insulate exposed pipes. Foam pipe insulation sleeves are inexpensive and available at any hardware store. Focus on pipes in unheated areas: crawl spaces, garages, attics, and the sections of exterior walls where supply lines run. A professional plumber can identify your highest-risk pipe runs during a pre-winter inspection.
Keep your thermostat above 55°F — even when away. Many burst pipe calls we receive come from homeowners who turned the heat down too low while on vacation. The cost of a slightly higher heating bill is far less than the cost of water damage cleanup and pipe repair. If you are leaving for more than a few days, consider shutting off the main water supply and draining the pipes entirely.
Open cabinet doors under sinks on exterior walls. Allowing warm air from your living space to circulate around under-sink plumbing can make a significant difference on the coldest nights. This is especially important for kitchen sinks on exterior walls, which are among the most common freeze points.
Let faucets drip during extreme cold snaps. When temperatures are forecast to drop below 10°F, let both the hot and cold taps drip slightly. Moving water is much harder to freeze than standing water. Focus on faucets served by pipes running through exterior walls.
Seal air leaks near pipes. Cold air infiltration through gaps around electrical outlets, cable pass-throughs, and pipe penetrations can dramatically lower the temperature around pipes inside your walls. Use caulk or spray foam to seal these gaps before winter arrives.
If you turn on a faucet and get little or no water, you likely have a frozen pipe. Do not panic — a frozen pipe has not yet burst. Here is what to do:
1. Locate the frozen section. Check pipes in unheated areas first. The frozen section will often feel very cold to the touch, or you may see frost on the outside of the pipe. 2. Open the faucet. Keep the affected faucet open so water can flow out as the ice melts. This also relieves pressure that could cause a burst. 3. Apply gentle heat. Use a hair dryer, electric heating pad, or warm towels to thaw the pipe slowly. Never use an open flame, as this is a serious fire hazard. 4. Call a plumber if you cannot locate the frozen section. Pipes inside walls require professional equipment to thaw safely. Attempting to thaw a pipe you cannot see can cause a burst that floods your home.
If you hear a popping sound, see water staining on walls or ceilings, or notice a sudden drop in water pressure, you may already have a burst pipe. Turn off your main water supply and contact our team at (315) 640-3590. Our trucks are stocked with the materials needed for common burst pipe repairs.
We also offer pre-winter pipe inspections to identify your home's most vulnerable pipe runs before the cold hits. Call us in October or November to schedule yours.
At what temperature do pipes freeze in Syracuse?
Pipes can begin to freeze when outdoor temperatures drop below 20°F, but the real danger zone is below 10°F, especially for pipes in unheated spaces or exterior walls with poor insulation.
How long does it take for pipes to freeze?
In extremely cold conditions (below 0°F), exposed pipes can freeze in as little as 6 hours. Pipes inside insulated walls typically take longer, but a sustained cold snap of several days can freeze even well-protected pipes.
Does homeowner's insurance cover burst pipe damage?
Most standard homeowner's policies cover sudden and accidental water damage from burst pipes. However, damage from gradual leaks or failure to maintain adequate heat may not be covered. Document everything and contact your insurer promptly.
Can I thaw frozen pipes myself?
Yes, if you can access the frozen section. Use a hair dryer or heating pad and work from the faucet end toward the frozen section. Never use an open flame. If you cannot locate or access the frozen pipe, call a licensed plumber.
