When winter blows in and the temperatures plummet, your water pipes may be in danger of freezing. And as water freezes, it puts pressure on your pipes, causing them to expand and burst.
Fortunately, you can avoid incidents like this. All you need to do is take a few steps to ensure cold water won’t freeze in your pipes when temperatures drop. Keep reading to find out how to keep your pipes from freezing.
Pipe insulation acts as a protective shield for your pipes, preventing the extreme cold from freezing the water in them. Consider wrapping your pipes in foam insulation or using heat tape. Focus on areas such as your basement or exterior walls where exposed pipes are at a greater risk of freezing.
If you aren’t sure which materials work or how to insulate your pipes, you can check with a plumber near you.
We’ve heard that a leaking faucet can cost you a lot of money. But in the winter, it can actually prevent your pipes from freezing. By allowing water to drip, a small amount of water can flow through your pipes. This relieves the pressure buildup and allows the water to move, which prevents it from freezing.
While lowering your thermostat to save money on energy sounds like a good idea, it may not be the best option for your pipes. Ideally, you should maintain a consistently warm temperature in your home — nothing more than 55° Fahrenheit. With a steady room temperature during the day and at night, you can help ensure your pipes stay warm, preventing them from freezing.
As you prepare your house for the cold weather, seal drafts near your doors and windows to keep the cold outside and the warmth inside. Doing this will help protect your pipes from the freezing weather, so you don’t need to worry about them during the winter.
Check for cracks and openings around windows, doors, and sill plates. If needed, add weatherstripping and caulk the crawl space around your doors and basement windows.

Pipe heat cables are thermostat-controlled heating cables that help protect your pipes. You can install them before winter arrives and then unplug them at the end of the season.
Follow the manufacturer's instructions when installing. Or, hire a plumber to handle this task for you.
If you’ve got old windows in your basement, consider installing storm windows over them. You can also replace all your old windows with more energy-efficient ones to keep your home warm and insulated throughout winter.
Even though temperatures may be freezing outside, you want warm air to circulate evenly throughout your home. Open cabinet doors and doors to your room to allow the heat to circulate pipes, especially for pipes under sinks and other unheated areas.
After you’re done with all your gardening and backyard work for the season, don’t forget to turn off, drain, and disconnect your hoses from your water supply lines. You may also want to drain any water from your sprinklers so they don’t freeze and get damaged. You can also install a faucet cover to help protect your plumbing from freezing during the winter.
If all else fails, you’ll want to turn off the water flow to the building immediately. Even before winter comes, make sure you know where the water master shut-off valve is and how to operate it.
If you’re planning for a vacation elsewhere outside your home, prep your home before you leave — especially your pipes. Shut off the main water supply, turn on all the faucets to drain the pipes, and flush the toilets. Such measures can eliminate any water remaining in your pipes, so there’s less chance of it freezing while you are away.
You may also want to leave the heat on in your home and set it to a temperature no lower than 55° Fahrenheit. If possible, get a neighbor, family member, or friend to check your house regularly to ensure that everything is working fine.
If your pipes have frozen, you’ll need to thaw them. You'll need to use a heat source, such as an electric hair dryer, towels soaked in hot water, or a portable space heater. You can find other heat sources to thaw frozen pipes as long as they don’t have open flames.
Apply heat until full water pressure is restored. Turn on your faucet so the water runs out and helps melt the remaining ice on the pipe.
