Winter can be tough on your plumbing. As temperatures drop, frozen pipes become a real threat, putting your home at risk of leaks, water damage, and expensive repairs. The problem starts when freezing temperatures cause water inside the pipes to expand. This expansion puts pressure on the walls, causing them to crack or burst.
Fortunately, you can protect plumbing in winter with the right steps and a little preparation. From insulating pipes to keeping water moving, a few small steps go a long way.
This blog will break it all down for you, so you’re not left scrambling if the cold strikes hard. TradeWorksNW is here to help you stay ahead of the cold.
Why Do Pipes Burst in Winter?
The Science Behind Frozen Pipes
Ever wonder why winter is so hard on your plumbing? When water freezes, it expands just enough to create immense pressure inside your pipes. If that pressure has nowhere to go, the pipe can crack or burst.
A 1/8-inch crack in a pipe can spew up to 250 gallons of water a day, causing flooding, serious structural damage, and the immediate potential for mold.
Pipes in unheated or poorly insulated areas, like basements, crawl spaces, or exterior walls, are the most vulnerable. In these spots, the cold air has direct access, making freezing more likely.
Another major issue is the “pressure point” phenomenon. When ice forms in one section of a pipe, it creates a blockage. Water trapped between the ice and a closed faucet builds up immense pressure, eventually forcing the pipe to rupture.
Common Risk Factors for Winter Pipe Bursts
Certain conditions increase the chances of frozen or burst pipes during winter. If your home has any of these vulnerabilities, it’s time to take action:
- Poor insulation
- Drastic temperature drops
- Pipes near exterior walls
- Outdated or corroded plumbing
- Vacant homes
- Homes in colder climates
In 2022, State Farm paid more than $181 million for over 9,000 claims related to frozen pipe damage, with the average claim costing over $20,000. Being aware of these risks is the first step toward burst pipe prevention and avoiding expensive repairs.
Warning Signs of Frozen Pipes
Physical Signs
Frozen pipes often give themselves away if you know what to look for. Keep an eye out for these warning signs:
- Frost on Pipes
If you notice frost or ice on exposed pipes, it’s a clear indicator that freezing is underway. - Bulging or Swollen Pipes
A pipe that looks stretched is under severe pressure from expanding ice inside. - Water Stains or Leaks
Damp spots near walls or ceilings could mean a pipe has started to crack or is leaking. - Frozen faucets or fixtures
If water flow is restricted in a sink or shower, the connecting pipe could be frozen.
Performance Issues
Frozen pipes also affect how your plumbing works. If water trickles or doesn’t flow at all when you turn on a faucet, there’s a good chance a section of your pipe is frozen.
You might also hear strange noises, like whistling or banging, which can indicate pressure buildup inside the pipes. These performance issues often happen right before a pipe bursts, so take them seriously.
Tips to Prevent Pipes from Bursting in Winter
Insulating Pipes
One of the best plumbing winterization tips is to insulate pipes in vulnerable areas. Use foam pipe sleeves or heat tape to cover exposed pipes, especially in basements, garages, and attics. The investment is small compared to the cost of repairing a burst pipe.
Keeping Water Flowing
Letting your faucets drip during freezing weather might seem wasteful, but it’s an easy way to prevent freezing. Moving water is much harder to freeze than stagnant water. The constant flow reduces pressure in the system and keeps your pipes safe from bursting.
Maintaining a Consistent Indoor Temperature
Temperature Setting | Impact on Plumbing |
Below 55°F | High risk of freezing, especially in exterior walls. |
55°F to 65°F | Moderate risk, unheated areas still vulnerable. |
65°F and above | Low risk, keeps most pipes warm and safe. |
Set your thermostat to at least 55°F, even when you’re away. Maintaining a steady indoor temperature helps prevent pipes from freezing.
Sealing Drafts and Vulnerable Areas
Even tiny drafts can let cold air reach your pipes. Check around windows, doors, and pipe entry points for gaps. Seal gaps with weather stripping or caulk, and consider spray foam for larger openings.
Winterizing Outdoor Plumbing
Start by disconnecting hoses and draining outdoor faucets. Shut off water to exterior spigots, then cover them with insulated caps to keep the cold out. To add an extra layer of protection, use insulated covers over outdoor fixtures.
