The winter season can bring beautiful weather and fun holiday activities, but it can also create risks for your home’s plumbing system. As temperatures drop, it is important to protect your home against cold-weather damage. One of the biggest threats you may face is frozen pipes. Below, we provide some of our best tips on how to protect your home from freezing temperatures this winter.
Why Do Pipes Freeze?
Before jumping into the proactive steps you can take, it is important to understand why pipes freeze. Pipes freeze when temperatures drop below freezing for an extended period. Uninsulated or poorly insulated pipes are at a higher risk, especially when exposed to cold outdoor air or drafts.
Cold, drafty air entering through cracks in your exterior walls or foundation can quickly chill pipes. Additionally, pipes that are rarely used are more susceptible to freezing because standing water freezes more quickly than moving water.
Top Pipes to Prioritize
Some pipes in your home are more vulnerable to freezing than others. These are the areas that should be prioritized to significantly minimize your risk. Pipes located in unheated areas of your home — like your attic, crawl space, basement, garage, or exterior utility closets — are at increased risk. Any pipes running along exterior walls, as well as outdoor plumbing fixtures like hose bibs, irrigation lines, and pool supply lines, also require extra protection.
During extreme cold snaps, even pipes underneath kitchen sinks and bathroom vanities may be at risk, especially if the cabinets sit against exterior walls. Closed cabinet doors prevent warm indoor air from reaching the plumbing underneath.
What Happens When a Pipe Freezes?
When the water inside a pipe freezes, several things can occur. As water turns to ice, it expands, which can pressurize the pipe and weaken or damage the piping material. In some cases, the pipe may crack. While the water remains frozen, you will temporarily lose access to water for drinking, cooking, cleaning, and bathing.
The real danger occurs after the ice thaws. Melted water may escape through cracks or damaged areas of the pipe, leading to leaks. Even a small amount of water can cause significant damage to flooring, walls, insulation, and other building materials. Excess moisture can also contribute to mold growth and structural deterioration if not addressed quickly.
Proactive Prevention Measures
Preparing your plumbing system before temperatures drop is the best way to prevent frozen pipes and costly water damage. Most preventative measures focus on minimizing cold air exposure and keeping water moving when temperatures become extreme.
Insulate Exposed Pipes
One of the most effective ways to reduce the risk of frozen pipes is to insulate any exposed pipes that remain in use during the winter. While you can typically shut off and drain exterior hose bibs, you may still rely on water lines in garages, basements, or utility areas. Using foam pipe sleeves, fiberglass wrap, or rubber insulation creates a protective barrier between your pipes and cold air.
For greater protection, you can install heat cables designed specifically for pipes. These cables use a built-in thermostat that activates when temperatures approach freezing. They are especially helpful in areas where pipes are difficult to insulate but do require proper installation and a reliable power source.
Seal Up Air Leaks
Another important step is eliminating drafts near your plumbing. Cold drafts can quickly chill pipes and increase the chance of freezing. Performing a walkthrough of your home and inspecting areas where plumbing runs can help you identify temperature changes or cold spots.
Air leaks are commonly found around door frames, window frames, foundation cracks, basement rim joists, attic hatches, dryer vents, and plumbing or wiring penetrations. Depending on the size of the opening, you can use expanding foam, weatherstripping, caulking, or insulation to seal the gap. The goal is to reduce cold air infiltration wherever plumbing is present.
Always Keep Your Heater On
One of the most reliable ways to prevent frozen pipes is to maintain a safe indoor temperature. Even if you are not home, keep your thermostat set to at least 55 degrees Fahrenheit. While this temperature does not guarantee protection in every situation — especially in poorly insulated areas — it significantly reduces the risk of freezing and helps keep warm air circulating through bathrooms, laundry rooms, and kitchens.
Use Extra Precautions During Cold Snaps
When temperatures fall into the teens or single digits for extended periods, take extra measures to protect your plumbing. Open cabinet and vanity doors to allow warm air to reach the pipes underneath. In problem areas, you can also allow faucets to drip slightly overnight. Moving water freezes more slowly than still water, which helps protect your pipes during extreme cold.
Winterize Outdoor Fixtures
Your outdoor plumbing fixtures are especially vulnerable to freezing and must be properly winterized. Disconnect all hoses, drain them completely, and store them indoors. Shut off water to exterior hose bibs and drain those lines fully. Winterizing your irrigation system and outdoor kitchen plumbing is also essential to prevent freezing damage.
What to Do If Your Pipe Freezes?
If you discover a frozen pipe, it is important to act quickly and safely to prevent a burst. First, ensure the affected faucet is turned on. This allows melted water to escape slowly and reduces pressure as the pipe thaws.
Next, locate the frozen section. You may notice frost, ice buildup, or unusually cold spots on the pipe. To thaw the pipe, use a safe heating method. Never use an open flame, as this can damage the pipe and create a fire hazard.
Instead, use a hair dryer, small space heater, or warm towels to apply gentle heat until the ice melts. Once thawed, inspect the pipe for cracks or damage. If you see any signs of leaking, shut off the water supply to that section immediately and schedule repair service.
