Tips to Prevent Frozen Pipes This Winter

Cold weather can do more than make you reach for a blanket. It can put your plumbing at risk. When temperatures drop, the water inside pipes can freeze and expand, creating enough pressure to crack or burst them. The result is not just a small leak but potentially hundreds or even thousands of gallons of water damaging your home.

The best way to avoid that nightmare is through prevention. With a few easy steps, you can protect your plumbing and rest easier when the temperature outside plummets.

1. Insulate the Most Vulnerable Pipes

Pipes that run through unheated areas, like basements, attics, garages, and crawl spaces, face the highest risk of freezing. Wrapping them in foam sleeves or fiberglass insulation adds an important layer of protection.

Outdoor spigots and supply lines need attention, too. Disconnect garden hoses, shut off the valve that feeds the outdoor faucet, and cover it with an insulated cap to keep cold air out.

2. Keep Warm Air Moving

Air circulation is an easy but often overlooked way to prevent frozen pipes. Open the doors to rooms that stay cooler and leave cabinet doors open under sinks that sit on exterior walls. Allowing heat from your furnace to flow around those pipes can make a significant difference.

It also helps to keep your thermostat steady. Avoid turning the heat too low at night or when you’re away. Consistent warmth keeps pipes above freezing.

3. Let Faucets Drip During Extreme Cold

When the temperature is expected to dip below freezing, let a few faucets trickle overnight. It doesn’t need to be much — just a steady drip. The constant flow relieves pressure inside the line and makes it harder for water to freeze.

Pay special attention to faucets connected to pipes that run along exterior walls or through unheated areas. A little dripping now can prevent a big problem later.

4. Seal Cracks and Air Leaks

Cold air that seeps through small cracks can lower the temperature around pipes quickly. Check for gaps near windows, doors, vents, and where pipes enter walls or floors. Use caulk or expanding foam to close them up.

This simple maintenance step helps your heating system run more efficiently and reduces the risk of a sudden freeze in areas you rarely check.

5. Know Where to Find Your Main Water Shut-Off Valve

Even with preparation, unexpected things happen. If a pipe bursts, the first few minutes matter. Knowing where your main water shut-off valve is located allows you to stop the flow immediately and limit water damage.

In most homes, the valve is near the water meter or where the main line enters the house. Make sure everyone in your household knows how to find it and turn it off.

Consequences of Not Prioritizing Frozen Pipe Prevention

Many homeowners underestimate how damaging a single frozen pipe can be. Once a pipe bursts, the water inside can flood walls, floors, and insulation within minutes. Repairs often include not just plumbing replacement but also drywall, flooring, and furniture restoration.

The cost adds up fast. Even a small crack can release several gallons of water each minute. Beyond the financial impact, it can also disrupt your home for weeks while cleanup and repairs take place. Taking preventive action before freezing weather hits avoids that stress completely.

How to Tell if a Pipe Might Be Frozen

Recognizing the warning signs early can help you act before a pipe bursts. Here are a few things to watch for:

• No water or reduced water flow from faucets
• Frost or condensation forming on visible pipes
• Strange clanging sounds when water tries to move through
• Unusual odors from drains or faucets

If you notice any of these symptoms, shut off the main water supply right away and contact a professional plumber.

How to Safely Thaw a Frozen Pipe

If you suspect a pipe is frozen but hasn’t burst, you can sometimes thaw it on your own with a few careful steps. Start by turning on the nearest faucet. Even a trickle helps relieve pressure and allows melted water to flow out as the ice softens.

Use a hair dryer, heating pad, or warm towel to apply gentle heat to the frozen section. Begin near the faucet and work backward toward the coldest area. Keep the heat steady and avoid open flames or high-powered heaters, which can cause pipes to crack or warp. If water doesn’t start flowing after about half an hour, or you can’t reach the frozen section safely, stop and call a plumber.
