When the temperature drops, one of the biggest worries for homeowners is frozen pipes. A burst pipe can flood your home, damage walls and floors, and lead to expensive repairs. Fortunately, with the right preparation, you can keep your plumbing safe and avoid the chaos of mid-winter leaks.

Why Pipes Freeze
Water expands when it freezes. Inside a pipe, that expansion creates pressure, often enough to make the pipe crack or burst. When the ice melts, the trapped water gushes out, flooding the area around it.
Pipes in unheated areas—like basements, attics, crawl spaces, and garages—are especially at risk. Even pipes running through exterior walls can freeze if the insulation isn’t strong enough.
Simple Steps to Stop Pipes from Freezing
The good news is you can take several easy steps to protect your pipes. Here’s how:
1. Insulate Pipes in Cold Areas
Pipe insulation is one of the most effective ways to prevent freezing. Foam pipe sleeves are inexpensive and easy to install. Measure your pipes and cut the insulation to fit. Pay attention to corners and joints, since those areas are most vulnerable.
You can also use heat tape or heat cables for pipes that run through very cold spaces. These products have built-in thermostats that turn on automatically when the temperature drops.
2. Seal Cracks and Gaps
Cold air can sneak in through tiny openings near pipes. Check for gaps around vents, electrical wiring, and where pipes go through walls or floors. Use caulk or expanding spray foam to seal those leaks.
Even small drafts can make a big difference. By closing off those entry points, you help keep warm air inside and cold air out.
3. Keep a Steady Indoor Temperature
Some homeowners lower the heat at night or when leaving for the weekend to save on energy bills. But if the temperature inside drops too low, it can lead to frozen pipes.
Try to maintain your thermostat at a consistent setting—ideally no lower than 55°F, even when you’re away. It’s also helpful to open cabinet doors under sinks to let warm air circulate around pipes, especially those along exterior walls.
4. Let Faucets Drip During Extreme Cold
When the temperature dips into single digits, let your faucets drip slightly. The slow flow of water helps relieve pressure in the pipes, making it less likely for them to burst.
It might seem like a waste, but the small amount of water you use is much cheaper than fixing water damage from a broken pipe.
5. Disconnect Garden Hoses and Drain Outdoor Faucets
Outdoor plumbing is often the first to freeze. Before winter sets in, disconnect all garden hoses and shut off the water supply to outdoor spigots.
Then, open the faucet to drain any remaining water. If you have a sprinkler system, drain and blow it out to prevent cracks in the lines.
6. Add Insulation in Attics, Basements, and Crawl Spaces
Many pipes run through unheated areas. Adding insulation to these spaces can help keep the temperature above freezing. You don’t have to go overboard—sometimes just sealing air leaks and adding a few rolls of fiberglass insulation can make a noticeable difference.
7. Keep Garage Doors Closed
If your home has water supply lines in the garage, keep the doors shut as much as possible during cold weather. Even a short burst of freezing air can cause pipes near the outer walls to cool rapidly.
8. Know How to Shut Off Your Water
Even with preparation, accidents can happen. Learn where your main water shut-off valve is located. If a pipe bursts, turning off the water immediately can minimize damage until help arrives.
Keep tools handy and make sure all family members know how to use the valve.
What to Do If Pipes Freeze
Sometimes, despite your best efforts, a pipe might still freeze. If you turn on a faucet and only a trickle comes out, here’s what you can do:
Keep the faucet open. As the frozen section begins to melt, water will start to flow, which helps melt the ice faster.
Apply gentle heat. Use a hair dryer, heating pad, or warm towels. Never use an open flame or blowtorch.
Check all faucets. If one pipe freezes, others might be close to freezing too.
Call a professional plumber if you can’t locate the frozen section or if the pipe has burst.
Never ignore a frozen pipe. Even if it doesn’t burst right away, the pressure buildup can cause problems later.
Long-Term Prevention Tips
Protecting your plumbing system isn’t just about one cold season. Here are ways to keep your home safe year after year:
Upgrade insulation, especially in older homes where insulation might be thin.
Replace old pipes that are prone to bursting.
Schedule annual inspections so a licensed plumber can identify hidden risks before winter.
Invest in smart sensors. Modern leak detectors can alert you to temperature drops or water leaks before they become disasters.
Common Myths About Frozen Pipes
Myth 1: Only metal pipes freeze.
Plastic pipes can freeze too. While they may be more flexible, they’re not immune to pressure from expanding ice.
Myth 2: Running water can’t freeze.
If water moves too slowly or the temperature stays low for long enough, even moving water can freeze.
Myth 3: Heat tape is dangerous.
Modern heat cables are safe when installed correctly. Always follow the manufacturer’s directions.
FAQs About Preventing Frozen Pipes
Q1: At what temperature do pipes start to freeze?
Pipes can begin to freeze when temperatures drop below 20°F, but homes with poor insulation might experience freezing at higher temperatures.
Q2: How do I know if my pipes are frozen?
Common signs include reduced water flow, frost on exposed pipes, or strange noises when you turn on the faucet.
Q3: Should I leave my heating on when I’m away during winter?
Yes. Keep your thermostat set to at least 55°F. You can also open cabinet doors and interior doors to allow better airflow.
Q4: Can I use space heaters to warm pipes?
Yes, but only with caution. Keep space heaters away from flammable materials and never leave them unattended.
Q5: Is it expensive to prevent frozen pipes?
Not really. Most prevention methods, like pipe insulation and sealing air leaks, cost far less than repairing water damage.
