🧊 How to Prevent Frozen Pipes This Winter—and What to Do If They Freeze

When winter hits hard, frozen pipes can turn into a costly nightmare for homeowners. A burst pipe can spill hundreds of gallons of water in just hours, damaging walls, floors, and valuables. But with a few proactive steps, you can protect your home and avoid the stress and expense.

Here’s how to prevent frozen pipes—and what to do if they freeze.

❄️ Why Do Pipes Freeze?

Pipes freeze when temperatures drop below 20°F, especially in unheated areas like basements, crawl spaces, attics, and garages. Water expands as it freezes, putting pressure on the pipe walls until they crack or burst.

🛡️ How to Prevent Frozen Pipes

Here are simple, effective ways to keep your pipes safe:

1. Insulate Vulnerable Pipes

• Use foam pipe insulation sleeves or heat tape for pipes in unheated areas.
• Pay special attention to pipes near exterior walls or windows.

2. Seal Air Leaks

• Caulk or weatherstrip gaps around windows, doors, and foundation cracks.
• Close vents and access points that let cold air into crawl spaces.

3. Keep the Heat On

• Maintain indoor temperatures above 55°F—even if you're away.
• Open cabinet doors under sinks to let warm air circulate around pipes.

4. Let Faucets Drip

• Allow a slow trickle of water from faucets connected to vulnerable pipes.
• Moving water is less likely to freeze.

5. Use Smart Thermostats and Leak Detectors

• Monitor temperatures remotely and get alerts if pipes are at risk.
• Some systems can even shut off water automatically if a leak is detected.

🚨 What to Do If Your Pipes Freeze

If you suspect a frozen pipe, act fast to prevent a burst:

1. Turn Off the Main Water Supply

• This reduces pressure and limits flooding if the pipe bursts.

2. Locate the Frozen Section

• Look for frost on the pipe or reduced water flow from faucets.

3. Thaw the Pipe Safely

• Use a hair dryer, heating pad, or space heater (never an open flame).
• Start near the faucet and work your way toward the frozen area.

4. Call a Licensed Plumber

• If you can’t locate or thaw the pipe, or if it’s already burst, professional help is essential.

🏠 Peace of Mind Starts with Prevention

Frozen pipes are preventable with a little preparation and vigilance. By insulating, sealing, and monitoring your home, you can avoid winter plumbing disasters and keep your home safe and dry.
