If you have lived in Buffalo for more than one winter, you already know the drill. Lake effect snow piles up overnight, temperatures drop into the single digits, and somewhere in the walls of an older home on the East Side or in a drafty ranch in Cheektowaga, a pipe quietly freezes solid.

When that pipe thaws — or worse, when it bursts before it gets the chance — you are looking at water damage, a flooded basement, and an emergency call to a plumber at 2 AM. We have seen it hundreds of times.

The good news: frozen pipes are almost entirely preventable. Here is everything you need to know to protect your home this winter.

Why Buffalo Homes Are Especially Vulnerable

Buffalo sits on the eastern end of Lake Erie, which means lake effect snow events can drop two to three feet of snow in 24 hours while temperatures plunge well below zero. The combination of extreme cold, high winds, and the older housing stock throughout the city creates ideal conditions for frozen pipes.

Many Buffalo homes were built in the 1920s through 1950s, when insulation standards were far lower than they are today. Pipes in exterior walls, crawl spaces, unheated garages, and unfinished basements are particularly exposed. Even a small gap in insulation — around a dryer vent, a cable entry point, or an old window frame — can let enough cold air in to freeze a pipe within hours.

The Pipes Most Likely to Freeze

Not all pipes are equally at risk. Focus your attention on these locations first:

Pipes in exterior walls. Any supply line running through an outside-facing wall is vulnerable, especially in older homes where the wall cavity has little or no insulation.

Pipes under kitchen and bathroom sinks on exterior walls. The cabinet doors block the warm air from the room. Open them on the coldest nights.

Pipes in unheated spaces. Garages, crawl spaces, attics, and unfinished basements all get cold enough to freeze pipes. If you have a utility room or laundry area in an unheated part of the house, those pipes need attention.

Hose bibs and outdoor spigots. These should be shut off and drained every fall before the first hard freeze. If you have a frost-free hose bib, make sure the hose is disconnected — a connected hose traps water in the pipe and defeats the frost-free design.

The main water line where it enters the house. In older Buffalo homes, the main line often comes through the foundation near the floor. If that area is drafty or uninsulated, it can freeze.

Step-by-Step: How to Winterize Your Pipes

1. Insulate Every Exposed Pipe

Foam pipe insulation sleeves are inexpensive and available at any hardware store. Wrap every exposed pipe in your basement, crawl space, and garage. Pay special attention to pipes near exterior walls and any pipe that runs through an unheated space.

For pipes in particularly cold areas, consider using heat tape (also called pipe heating cable) in addition to insulation. Heat tape plugs into an outlet and keeps the pipe above freezing even in extreme cold. Follow the manufacturer's instructions carefully — improperly installed heat tape is a fire hazard.

2. Seal Air Leaks Near Pipes

Cold air infiltration is the hidden culprit in many frozen pipe situations. Walk around your basement and look for gaps where pipes, wires, or cables pass through exterior walls or the rim joist (the framing at the top of your foundation wall). Seal those gaps with spray foam or caulk.

Check around dryer vents, exhaust fans, and any other penetrations in exterior walls. Even a small gap can funnel enough cold air to freeze a nearby pipe.

3. Keep the Heat On — Even When You Are Away

This is the one that catches people off guard. You leave for the holidays, you turn the thermostat down to 55°F to save money, and you come home to a burst pipe and a flooded living room.

Keep your thermostat set to at least 55°F when the house is unoccupied. The cost of the extra heat is a fraction of what a water damage claim will cost you.

If you are leaving for more than a few days during a cold snap, consider shutting off the main water supply and draining the pipes. Ask a neighbor to check on the house, or install a smart thermostat that alerts you if the temperature drops unexpectedly.

4. Open Cabinet Doors Under Sinks

On nights when temperatures are forecast to drop below 10°F, open the cabinet doors under kitchen and bathroom sinks that are on exterior walls. This lets the warm air from the room circulate around the pipes.

5. Let a Trickle of Water Run

Moving water is much harder to freeze than standing water. On the coldest nights, let a thin trickle of water run from a faucet served by a pipe that runs through an exterior wall or unheated space. It does not need to be more than a slow drip — just enough to keep water moving.

6. Disconnect Garden Hoses Before November

Every fall, before the first hard freeze, disconnect all garden hoses from outdoor spigots. Even frost-free hose bibs can freeze if a hose is left connected, because the hose traps water in the pipe. Shut off the interior valve that feeds outdoor spigots and open the outdoor faucet to drain any remaining water.

What to Do If Your Pipes Freeze

If you turn on a faucet and get little or no water, or if you hear a strange gurgling sound from the pipes, you may already have a frozen pipe. Here is what to do:

Do not panic — yet. A frozen pipe has not necessarily burst. If you act quickly, you may be able to thaw it before it fails.

Locate the frozen section. Check pipes in the areas described above — exterior walls, under sinks, in unheated spaces. Feel along the pipe for a section that is colder than the rest, or look for frost on the outside of the pipe.

Apply gentle heat. Use a hair dryer, a heating pad, or warm towels to slowly warm the frozen section. Start at the faucet end and work back toward the cold section. Never use an open flame — a torch or heat gun can damage the pipe, ignite nearby materials, or cause a steam explosion inside the pipe.

Keep the faucet open. As the ice melts, water and steam need somewhere to go. Keeping the faucet open relieves pressure and lets you know when flow has been restored.

Check for leaks. Once the pipe thaws, inspect the entire section carefully for cracks or splits. A pipe that has frozen may have already cracked — the leak just has not appeared yet because the ice is still plugging the hole.

Call a plumber if you cannot locate or thaw the pipe. If the frozen section is inside a wall, under a slab, or in a location you cannot safely access, call us. Trying to open a wall yourself to get to a frozen pipe can cause more damage than the freeze itself.

If a Pipe Bursts

A burst pipe is a plumbing emergency. The moment you hear water rushing inside a wall or see water coming through a ceiling or floor, shut off the main water supply immediately. The shutoff valve is usually near the water meter — in Buffalo homes, that is typically in the basement near the front of the house.

Once the water is off, call us. Our emergency plumbing team is available 24 hours a day, 7 days a week, including during blizzards and holiday weekends. We serve Buffalo, Cheektowaga, Amherst, and all of Erie County.

One More Thing: Know Where Your Main Shutoff Is

Before winter arrives, make sure every adult in your household knows where the main water shutoff valve is and how to turn it off. In a burst pipe emergency, every second counts. If you cannot find your shutoff or it is stuck, call us — we can locate it and make sure it is working properly.
