How to Prevent Your Pipes from Bursting During Winter Freezes and Cold Snaps

2026-06-13 | By Emergency Team

Insulate Your Pipes

Proper insulation is essential to prevent your pipes from freezing. Cold air can penetrate even small cracks, causing the water inside to expand and potentially burst the pipe. Use foam pipe insulation sleeves or fiberglass tape to wrap around exposed pipes, especially in unheated areas like crawl spaces, basements, and attics. For outdoor pipes, consider using insulated pipe covers or even burying them deeper in the ground to provide additional protection.

Seal Air Leaks

Air leaks around windows, doors, and walls can allow cold air to reach your plumbing, increasing the risk of freezing. Check for drafts and seal them with caulk or weatherstripping. Pay special attention to areas where pipes run through walls or floors, as these are common weak points. Sealing these gaps not only prevents freezing but also improves energy efficiency by reducing heating costs.

Let Faucets Drip

During extreme cold snaps, allowing a faucet to drip can help prevent pipes from freezing. Even a slow drip keeps water moving, reducing the risk of expansion pressure building up inside the pipes. Focus on letting faucets drip in areas with exposed pipes or those near exterior walls. This is a simple yet effective measure that can save you from costly repairs.

Open Cabinet Doors

In cold weather, keep cabinet doors under sinks open to allow warm air to circulate around the pipes. This helps maintain a more stable temperature and reduces the likelihood of freezing. If your kitchen or bathroom sink is located on an exterior wall, this is particularly important. Simply opening the cabinet doors can make a significant difference in protecting your plumbing.

Keep Temperatures Consistent

Fluctuations in temperature can make it harder for pipes to withstand freezing. Set your thermostat to a consistent temperature, even when you're away or sleeping. Ideally, keep it above 55°F (13°C) to protect vulnerable pipes. If you're going on vacation during cold weather, consider setting your thermostat even higher or draining your plumbing system if you're leaving for an extended period.

Use Heat Traces

For added protection, install electric heat tracing systems on vulnerable pipes. These systems use cables that emit heat to keep pipes above freezing temperatures. They are especially useful for pipes in unheated areas or those prone to freezing. While they require an electrical connection, they provide reliable protection against bursts.

Check Outdoor水管

Outdoor hoses, sprinkler systems, and water fountains are susceptible to freezing. Disconnect hoses and drain outdoor faucets before winter arrives. If you have an in-ground sprinkler system, drain the water from the pipes by shutting off the main supply and opening the valves at each喷头 to release any remaining water. For water fountains, use a non-toxic liquid deicer to prevent freezing.

Know Your plumbing

Area Risk Level Preventive Measure
Crawl Spaces High Insulate pipes and seal gaps
Basements Medium Insulate exposed pipes and seal air leaks
Attics High Insulate pipes and ensure proper ventilation
Outdoor Walls High Insulate pipes and seal gaps

Prepare for Emergencies

Despite taking precautions, winter storms can still cause unexpected issues. Know where your main water shut-off valve is located and how to turn it off in case of a burst pipe. Keeping a pipe repair kit with tools like pipe wrenches, tape, and epoxy can help you make temporary fixes until professional help is available. Additionally, consider purchasing a freeze alarm that can alert you if temperatures drop below a certain threshold.
