Pipe Is Frozen? What to Do When Your Pipes Freeze

If your pipes freeze, shut off the main water valve first — turn it clockwise where the line enters your home — then open a faucet downstream so pressure can’t build behind the ice. Thaw the pipe gently with a hair dryer or hot towels, never an open flame. Here’s how to spot a frozen pipe, thaw it safely, and know when it’s time to call a Capital Region plumber.

How to Tell If a Pipe Is Frozen

The first sign is usually a faucet that sputters or barely trickles when you open it on a freezing morning. Pay attention to these clues before you assume it is something else:

• Only one fixture or one part of the house has no water, while the rest works fine.
• You see frost or a bulge on an exposed pipe in a basement, crawl space, or under a sink.
• A foul smell backs up from a drain, which can mean a frozen drain line.
• The pipe feels ice-cold and the line runs along an exterior wall or unheated space.

Shut Off the Water First

If you suspect a pipe is frozen, your top priority is limiting damage if it has already cracked. Locate your main water shut-off valve, usually near where the water line enters the home or close to the water meter, and turn it clockwise to close it. Then open a faucet downstream of the frozen section so any thawing water has somewhere to go and pressure does not build up behind the ice. Knowing where this valve is before an emergency strikes is one of the smartest things you can do as a homeowner.

Thawing a Frozen Pipe Safely

Once water flow is controlled, you can try to gently thaw an accessible pipe. Work slowly and keep the faucet open so you can see when flow returns.

• Apply gentle heat with a hair dryer, a heating pad wrapped around the pipe, or towels soaked in hot water.
• Start near the faucet end and work back toward the coldest section so melting water can escape.
• Open cabinet doors under sinks to let warmer room air reach the pipes.
• Keep the hair dryer, heating pad and any cord away from standing water.

Never use an open flame, a propane torch, or a kerosene heater on a pipe. Direct fire can damage the pipe, scorch nearby framing, and start a house fire. If the frozen section is inside a wall or somewhere you cannot reach, it is time to bring in a professional rather than guess.

What to do if a frozen pipe has burst

• Shut off the main water valve right away. If you cannot reach it, shut off the valve nearest the break.
• Open the faucets to drain the lines, and open the lowest one to empty the house.
• If water is near outlets, the panel or appliances, stay out of the area and shut off power only if you can reach the switch safely and dry. Otherwise leave the house and call.
• Turn off the water heater, or its power, before draining the house.
• Move belongings out of the way, soak up standing water and take photos of the damage for your records.
• Call a plumber. A split pipe has to be cut out and replaced, and the break is often not at the spot where the ice sits.

A frozen pipe usually splits because ice blocks the pipe and the pressure between the ice and a closed faucet climbs until the wall of the pipe gives. That is why the split can be several feet from the frozen section, and why a thawed pipe should be checked for leaks once the water is back on.

Which pipes freeze first

• Pipes in exterior walls and under sinks on outside walls.
• Runs in crawl spaces, garages, attics and any basement area the furnace does not reach.
• Outdoor spigots and hoses left connected.
• Any pipe near a gap that lets in cold air, such as a dryer vent, a cable hole or a rim joist with no insulation.

When to Call a Plumber

Some situations are beyond a DIY fix, and waiting can turn a frozen pipe into a flooded floor. Reach out for professional help when:

• You cannot find the frozen section or it runs behind a wall or ceiling.
• A pipe has already split or you see water leaking once things start to thaw.
• Multiple pipes are frozen or the problem keeps coming back every cold night.
• You are not comfortable locating the shut-off valve or working around the lines.

How much does it cost to fix frozen pipes?

It depends on what happened. A pipe that froze but did not split may need only a careful thaw. A split pipe has to be cut out and replaced, and the cost depends on where it is, how easy it is to reach, what the pipe is made of and how much water got out. Pipes inside a wall or ceiling cost more to reach than pipes in a basement. We find the break first and quote the repair before work starts; see water line repair for a buried or entry-point break and repiping for failing pipe inside the house.

Family-run since 2006, we help Capital Region families with frozen and burst pipes, and same-day service within business hours is offered when the schedule allows. If water is running, shut off the main first and see emergency plumbing.

Preventing Frozen Pipes Next Time

Once the immediate crisis is handled, a few simple habits keep it from happening again. Insulate exposed pipes in your basement, crawl space, and garage with foam sleeves. On the coldest nights, let a vulnerable faucet drip slightly and open cabinet doors to share warm air. Keep your thermostat steady day and night, and if you travel in winter, never set the heat below 55 degrees. Disconnect and drain outdoor hoses before the first freeze so spigots do not back ice into the wall.

Before-winter checklist for your pipes

• Learn where your main shut-off is now, and check that it turns.
• Wrap foam sleeves around pipe that runs through the basement, crawl space or garage.
• Close gaps where cold air reaches pipe, such as at a dryer vent or a cable entry.
• Detach garden hoses from spigots and let them drain before a hard freeze arrives.
• If the house will sit empty, keep the heat on and have someone look in on it. See the winter plumbing and HVAC guide.

Frozen pipes are a January and February problem here. Our own job records for 2022 to 2025 put 82 of 128 frozen- and burst-pipe jobs in January and February. The time to insulate is before the new year.
