What to Do If Your Pipes Freeze: A Homeowner’s Guide

Understanding Frozen Pipes
Why Do Pipes Freeze?
When temperatures drop in the winter, the water inside your pipes can freeze. As water turns into ice, it expands, increasing pressure inside the pipe. This can cause blockages or even lead to pipes bursting, resulting in water damage and expensive repairs.
Pipes in unheated areas like basements, crawl spaces, attics, and exterior walls are the most vulnerable to freezing.
At What Temperature Do Pipes Freeze?
Pipes can freeze when temperatures reach 20°F (-6°C) or lower for an extended period. However, wind chills, poor insulation, and exposure to cold drafts can make pipes freeze at slightly higher temperatures.
How to Prevent Pipes from Freezing
The best way to avoid frozen pipes is by taking preventive measures before the temperature drops.
Simple Steps to Protect Your Plumbing
✔ Insulate exposed pipes in unheated areas like basements and attics.
✔ Seal any cracks or gaps in walls and around pipes to keep cold air out.
✔ Disconnect outdoor hoses and turn off exterior faucets.
✔ Let faucets drip slightly to keep water moving.
✔ Keep cabinet doors open under sinks to allow warm air to circulate.
✔ Maintain a consistent indoor temperature of at least 55°F, even when away.
✔ Have someone check your home if you’re traveling during cold weather.
By taking these steps, you can significantly reduce the risk of frozen pipes.
How to Tell If Your Pipes Are Frozen

If you suspect a frozen pipe, look for these warning signs:
đźš± Little or no water flow from faucets
❄️ Frost or condensation on exposed pipes
🔊 Whistling, banging, or gurgling noises from pipes
đź’¦ Bulging or cracked pipes
🛑 Water stains or puddles near walls and ceilings
🦠Bad smells coming from drains (a sign of ice blockage)
If you notice these signs, act quickly to prevent a burst pipe.
How to Thaw Frozen Pipes Safely
If your pipes freeze, don’t panic. Follow these steps to safely thaw them and restore water flow.
Step 1: Open the Faucet
Turn on the affected faucet slightly to relieve pressure. This helps water start flowing once the ice melts.
Step 2: Apply Heat to the Frozen Section
Use one of these safe methods to warm the pipe:
✔ Hairdryer – Start near the faucet and work your way toward the blockage.
✔ Heating pad – Wrap it around the frozen section of the pipe.
✔ Hot towels – Soak towels in warm water and wrap them around the pipe.
✔ Space heater – Place it near (but not touching) the frozen pipe.
đźš« DO NOT use open flames, propane torches, or any direct heat source that could damage the pipe or cause a fire.
Step 3: Keep Heating Until Water Flows
Continue applying heat until full water pressure is restored. Once the pipe is thawed, leave the faucet running for a few minutes to flush out any remaining ice.
Step 4: Check Other Faucets
If one pipe is frozen, others may be as well. Check all faucets, especially those along exterior walls.
What to Do If a Pipe Bursts
If a frozen pipe bursts, immediate action is necessary to prevent major water damage.
🚨 Shut off the main water supply immediately.
⚡ Turn off electricity in affected areas if water is near outlets or appliances.
đź› Drain faucets to reduce pressure in the system.
đź“ž Call an emergency plumber for professional repairs.
🧹 Remove standing water as quickly as possible to prevent mold and structural damage.
If the damage is severe, you may also need to call a water damage restoration service.
How Long Does It Take to Unfreeze Pipes?
Thawing frozen pipes can take anywhere from 30 minutes to several hours, depending on:
- The severity of the freeze (light vs. deep freeze)
- The pipe’s location (exposed vs. enclosed)
- The heating method used
If pipes remain frozen after an hour of heating, call a plumber to avoid further complications.
