Did you know that Burst pipes cause an average of $5,000 in water damage – According to the Insurance Institute for Business & Home Safety (IBHS), a single burst pipe can result in thousands of dollars in repairs.
Frozen pipes are one of winter’s most frustrating (and expensive) plumbing problems. When water freezes inside a pipe, it expands, increasing the risk of bursting. A burst pipe can cause thousands of dollars in water damage—not exactly the winter surprise anyone wants.
The good news? Preventing frozen pipes is easier than you might think. Whether you’re dealing with a deep freeze or just an occasional cold snap, these simple tips will help keep your pipes safe all winter long.
Why Do Pipes Freeze?
When temperatures drop below freezing (32°F or 0°C), the water inside pipes can turn to ice. As it freezes, it expands, putting pressure on the pipe walls. If the pressure becomes too much, the pipe can burst, leading to costly water damage.
Which Pipes Are Most at Risk?
Some pipes are more vulnerable than others. Keep an eye on:
- Exterior pipes (outdoor hose bibs, sprinkler lines, pool supply lines)
- Pipes in unheated areas (basements, attics, crawl spaces, garages)
- Pipes along exterior walls (especially in older homes with poor insulation)
How to Prevent Pipes from Freezing
You don’t need a major home renovation to protect your plumbing—just a few smart strategies can keep your pipes from freezing.
1. Keep the Heat On
Even if you’re away, keep your thermostat set to at least 55°F (13°C). A little extra on your heating bill is way cheaper than a burst pipe repair.
2. Let Faucets Drip
Running water doesn’t freeze as easily as standing water. Letting your faucets drip—especially those connected to exposed pipes—can relieve pressure and help prevent freezing.
3. Insulate Your Pipes
Pipe insulation is one of the best defenses against freezing. Use:
- Foam pipe insulation for exposed pipes in basements, attics, or garages.
- Heat tape or heating cables for pipes in extra-cold areas.
- Newspaper or rags as a temporary fix in an emergency.
4. Seal Cracks and Gaps
Cold air sneaking into your home can freeze nearby pipes. Seal gaps around:
- Windows
- Doors
- Where pipes enter the house
Use caulk or expanding foam to block drafts and keep warm air inside.
5. Open Cabinet Doors
If you have pipes under kitchen or bathroom sinks, open the cabinet doors to let warm air circulate. This is especially helpful for pipes against an exterior wall.
6. Disconnect Outdoor Hoses
Leaving a garden hose attached can trap water in the spigot and cause freezing. Before winter hits:
- Disconnect and drain hoses
- Shut off outdoor water supply
- Cover outdoor faucets with an insulated cover
What to Do If Your Pipes Start Freezing
Despite your best efforts, you might still end up with a frozen pipe. Here’s what to do:
Signs of a Frozen Pipe
- No water or only a trickle from the faucet
- Frost on the outside of the pipe
- Strange smells coming from drains
How to Thaw a Frozen Pipe
If you suspect a pipe is frozen, act fast to prevent bursting:
✅ Turn on the faucet (even a slow drip helps)
✅ Apply gentle heat using:
- A hairdryer
- A heating pad
- Towels soaked in warm water
✅ Warm the room (turn up the heat or use a space heater)
🚫 Avoid using an open flame (like a torch) as it’s a fire hazard.
Long-Term Solutions for Pipe Protection
Want to avoid dealing with frozen pipes every winter? Consider these long-term solutions:
✔ Install a smart thermostat – Helps maintain a steady temperature, even when you’re not home.
✔ Re-route exposed pipes – If you’re remodeling, move pipes away from exterior walls.
✔ Upgrade to freeze-resistant pipes – PEX piping is more flexible and less likely to burst.
What to Do If a Pipe Bursts
A burst pipe can cause significant damage, so act quickly:
- Shut off the water immediately at the main valve.
- Turn off electricity if water is near electrical outlets.
- Drain the faucets to relieve pressure.
- Soak up excess water with towels or a wet/dry vacuum.
- Call a plumber ASAP to assess the damage.
- Document everything for insurance purposes.
Stay Proactive and Avoid Costly Repairs
Preventing frozen pipes is all about staying proactive. A little insulation, a dripping faucet, and some basic winter prep can save you from a major headache.
