Frozen water pipes break because they are not winterized correctly. If you live in an area where the temperature drops below freezing, it's essential to take steps to protect your pipes from freezing.
Exposing pipes in unheated areas like the garage, basement, or crawlspace can be a recipe for disaster. These areas are often the first to freeze, and pipes in these areas are more likely to burst.
In areas with extremely cold temperatures, pipes can freeze in as little as 30 minutes. This is especially true for pipes that are not insulated or are located near exterior walls.
If you're not sure how to winterize your pipes, consider hiring a professional to do the job for you.
Causes and Prevention
Frozen water pipes can break because of a combination of factors, including extreme cold temperatures, lack of insulation, and poor maintenance. Frozen pipes are a common issue during winter months, but there are steps you can take to prevent them.
Keep your heating system running, even if you leave for a period of time. This will help keep your home warm and prevent pipes from freezing.
Locate pipes at risk of freezing and add insulation to them. High-risk zones include the garage, crawl space, attic, unfinished basement, and other unheated or poorly insulated areas indoors. Your local hardware store should have pipe insulation, or pipe sleeves, as well as outdoor spigot covers and other insulating products.
Outdoor plumbing should also be protected, if possible. Disconnect garden hoses and drain your sprinkler system. You don't want water trapped in there, waiting to freeze and expand.
Here are some key areas to check for exposed pipes and add insulation:
- Basement
- Crawl space
- Attic
- Garage
- Under kitchen and bathroom cabinets
By taking these preventative measures, you can reduce the risk of frozen pipes and avoid costly repairs.
Identifying Frozen Pipes
A water line coated in frost is a good sign that a pipe is frozen. This is a clear indication that you need to take action to prevent further damage.
If your faucets won't flow and your toilets won't refill following a flush, that's a good sign your pipes are frozen. This is a common symptom that can't be ignored.
Pipes that most frequently freeze are those that are exposed to extreme cold, like outdoor hose bibs, attics, swimming pool supply lines, water sprinkler lines, and water supply pipes in unheated interior areas.
If there’s no water coming out of your faucet, your toilet won’t refill after flushing, or a water line is coated in frost, then a pipe is probably freezing somewhere in your home. This is a crucial moment to take action.
To narrow down the location of the freezing pipe, you’ll need to turn off the main water supply and turn on all the faucets in the house. See which ones are not working.
If no faucets work, it's likely somewhere close to where the main service line enters the house. This is a common location for frozen pipes to occur.
If all the faucets in an area of the house don't work, it’s likely between the split from the main water line. This can be a challenging location to access, but it's essential to locate the frozen pipe.
If you are unable to locate the frozen area or the frozen area is not accessible, call a licensed plumber near you. Don't try to tackle the problem on your own, as this can lead to further damage and costly repairs.
Thawing and Repair
Thawing frozen pipes requires attention to prevent damage. Shut off the water supply to the affected section of plumbing to prevent further damage.
Use a space heater, heat lamp, or hair dryer to thaw the frozen length of pipe. Wrapping freezing pipes with thermostatically controlled heat tape can also quickly thaw a trouble spot.
The safest way to thaw a frozen pipe is to wrap the troubled area in thermostatically controlled heat tape. Avoid using an open flame, such as a propane torch, which presents a fire risk.
Here are some safe methods to apply heat to the section of pipe:
- Electric heating pad wrapped around the pipe
- Electric hair dryer
- Portable space heater (kept away from flammable materials)
- Towels soaked in hot water
Thawing a Frozen Pipe
Thawing a frozen pipe is a process that requires some care and attention to detail. You'll want to shut off the water supply to the affected section of plumbing before you start.
First, locate the frozen pipe and open the affected faucet all the way. This will help water flow through the pipe as it thaws, preventing further damage. Running water through the pipe will help melt ice in the pipe, making it easier to thaw.
There are a few ways to thaw a frozen pipe, but the safest method is to use thermostatically controlled heat tape. This can be wrapped around the pipe to provide a steady, controlled heat source. Be sure to follow the manufacturer's instructions for application and temperature settings.
If you're unable to locate the frozen area or if it's not accessible, it's best to call a professional plumber for assistance. They'll have the necessary equipment and expertise to safely thaw and repair the pipe.
Some common places for frozen pipes include against exterior walls or where the water service enters your home through the foundation. If you suspect you have a frozen pipe, apply heat to the section of pipe using an electric heating pad, an electric hair dryer, or a portable space heater.
Here are some heat sources you can use to thaw a frozen pipe:
- Electric heating pad
- Electric hair dryer
- Portable space heater (kept away from flammable materials)
- Towels soaked in hot water
Remember to avoid using open flame devices, such as blowtorches or propane heaters, as they can pose a fire risk.

Take Preventative Action in Cold Weather
Keep your garage doors closed if there are water supply lines in the garage. This simple step can help prevent pipes from freezing.
To protect your home from frozen pipes, keep your heating system running, even if you leave for a period of time. Keeping your home thermostat set above 50 degrees Fahrenheit should provide enough heat to keep the pipes warm.
Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. This will help prevent pipes from freezing, especially at night.
Let the cold water drip from the faucet served by exposed pipes. Running water through the pipe – even at a trickle – helps prevent pipes from freezing.
Consider installing specific products made to insulate water pipes, such as pipe sleeves or heat tape. You can also add space heaters to these areas on extremely cold days and nights.
Here are some steps to take before the onset of cold weather:
- Keep garage doors closed if there are water supply lines in the garage
- Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing
- Let the cold water drip from the faucet served by exposed pipes
- Keep the thermostat set to the same temperature both during the day and at night
- If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F
Frequently Asked Questions
Why do frozen water pipes break biology?
Frozen water pipes break due to the expansion of water as it freezes, causing increased pressure inside the pipes. This pressure buildup can lead to pipe rupture.
At what temperature do water pipes burst?
Water pipes typically burst when temperatures drop to 20°F (-7°C) or lower. Protecting your pipes from freezing temperatures is crucial to prevent costly damage.
