Oct 21, 2025 | Plumbing, Plumbing Repair, Poly B Replacement

As any Calgary homeowner knows, winter here isn’t just cold; it’s extreme. Long stretches of subzero temperatures, freezing winds, and sudden weather changes can seriously damage your home’s plumbing system. Frozen or burst pipes, leaky water heaters, and drainage issues are common problems during the cold months.How To Prepare Your Plumbing for Calgary’s Harsh Winters. leaky water heaters.

Taking preventive steps now will save you from the stress and expense of mid-winter plumbing emergencies.

Why Winter Plumbing Preparation Is Essential in Calgary

Water expands when it freezes. If that water is trapped inside your pipes, it creates enough pressure to cause cracks or full bursts, even in modern plumbing. Calgary’s intense freeze-thaw cycles make this a common problem. Once a pipe bursts, you could face major water damage and costly repairs.

Investing in plumbing winterization before the deep freeze sets in can protect your home, reduce energy costs, and keep your water flowing reliably. Our Calgary plumbers recommend starting preparations in early fall to ensure your system is ready before temperatures drop sharply. 

As a locally owned and operated company, Aquality knows the challenges Calgary homeowners face every winter, and we tailor our services to protect your home through even the harshest conditions.

Insulate Exposed Pipes for Frozen Pipe Prevention

Insulating exposed pipes is one of the simplest and most effective ways to prevent freezing. Pipes in unheated areas such as basements, garages, or crawl spaces are the most vulnerable. While heat tape can help protect exposed lines, plumbing lines should never be run through exterior walls or unheated spaces as per building code. Ensure outdoor hose taps are properly winterized each fall to prevent freezing.

Our team offers professional pipe insulation as part of our frozen pipe prevention services in Calgary. We inspect your home to locate high-risk areas and apply the right materials to ensure long-term protection. 

A little insulation goes a long way toward avoiding burst pipes and unnecessary emergency calls later in the season. With Aquality’s 24/7 emergency support, you’ll never be left without help if something unexpected happens.

Disconnect and Drain Outdoor Fixtures

Outdoor faucets and garden hoses are often the first parts of a plumbing system to freeze. Before winter sets in, disconnect all hoses, drain them completely, and store them indoors. Shut off the water supply to outdoor faucets and open the valves to escape any trapped water.

If your home has an in-ground sprinkler system, ensure it’s properly blown out before the first freeze. Our Calgary plumbing services include professional winterization for outdoor plumbing systems, ensuring that every line is dry and safe until spring. Aquality’s experienced technicians handle this process efficiently and can travel anywhere within Calgary and its surrounding communities.

Service and Inspect Your Water Heater

Nothing is worse than running out of hot water on a freezing Calgary morning. As part of your winter plumbing checklist, have your water heater serviced to ensure it’s performing efficiently. Over time, sediment builds up inside the tank, reducing heating efficiency and stressing the system.

Our licensed Calgary plumbers can flush your tank, inspect the anode rod, and test the thermostat to keep your water heater running smoothly. If your unit is nearing the end of its lifespan, we’ll help you choose an energy-efficient replacement that can handle Calgary’s cold temperatures. 

Insulating your hot water tank and nearby pipes can also improve efficiency and reduce energy costs. At Aquality, we pride ourselves on honest recommendations. We never upsell or earn commissions, ensuring every suggestion is made with your best interests.

Seal Air Leaks Around Plumbing Lines

Drafts can be a hidden enemy during winter. Cold air seeping through cracks where plumbing pipes enter your home can quickly freeze nearby lines. Inspect areas under sinks, in utility rooms, and along basement walls. Use caulking or spray foam to seal gaps and prevent cold air from reaching your pipes.

During a winterization inspection, our plumbers often identify these small but critical vulnerabilities and fix them before they become major issues. Air sealing protects your plumbing and improves your home’s overall energy efficiency. As a company built on communication, reliability, and attention to detail, Aquality ensures you always know what’s being done and why. There are no surprises, just trustworthy workmanship.

Maintain a Consistent Indoor Temperature

Another key to frozen pipe prevention in Calgary is keeping your home consistently warm. Sudden temperature drops, even indoors, can cause pipes to freeze overnight. Keep your thermostat set to at least 16°C (60°F) and avoid turning off the heat when you’re away. If you’re travelling, set the heat to a steady temperature and open cabinet doors under sinks to allow warm air to circulate pipes. 

We also install smart thermostats and leak detection systems that let you monitor and control your home’s plumbing while you’re away. This is part of our commitment to helping Calgary homeowners stay comfortable and protected year-round.

Test and Maintain Your Sump Pump

Winter isn’t the only concern, as spring thaw can bring sudden flooding. A working sump pump helps protect your basement from melting snow and groundwater. Test your pump by pouring a bucket of water into the sump pit and confirming it activates properly.How To Prepare Your Plumbing for Calgary’s Harsh Winters. Test and Maintain Your Sump Pump.
