How to Get Your Calgary and Area Home Ready for the Winter

Updated October 2026

Alberta winters are hard on houses. Cold snaps, heavy snow, and Chinook warm-ups that melt everything by afternoon and refreeze it overnight all put stress on a home. A few hours this fall can save you from frozen pipes, ice damage, and a cold house in January.

This list is written for Calgary and area homeowners. It starts with what’s most time-sensitive and works toward the things you can do any weekend.

Do these before the first hard freeze

• Outdoor hose bibs: Disconnect hoses, shut off the interior valve to each outdoor tap, and drain the line. Even frost-free taps can freeze if a hose is left attached.
• Irrigation system: Have the lines blown out and the system shut down. Water left in the lines can crack them.
• Gutters and downspouts: Clear leaves and debris, and make sure downspouts direct water well away from the foundation. Clogged gutters are one of the common contributors to ice buildup at the roof edge.
• Window wells: Clear out debris and check that there’s a gap between the bottom of the well and the window, so snowmelt has somewhere to go besides inside.
• Roof and shingles: A quick look from the ground for loose, lifted, or missing shingles. If anything looks off, a roofer can tell you more than a visual check can.

Furnace and indoor air

• Book a furnace inspection and cleaning with a licensed technician before it’s running hard.
• Replace the furnace filter, and keep a spare or two on hand.
• If you have a humidifier, replace the pad and set it for winter. As outdoor temperatures drop, the humidity level your windows can tolerate drops with them, so condensation on the glass is your cue to turn it down.
• Check the thermostat cycles the furnace properly and replace the batteries if it uses them.
• Check your carbon monoxide detectors. Replace the batteries, and check the expiry date on the unit, since they have a limited lifespan.

Plumbing and water

• Know where your main water shut-off is, and make sure everyone in the house does too. If a pipe does fail, minutes matter.
• Insulate exposed pipes in unheated areas like garages, crawl spaces, and exterior walls.
• If you have a sump pump, confirm it runs. Freeze-thaw weather is when it gets used.
• Clear the dryer vent and the lint trap line. It improves airflow and reduces fire risk.

Sealing and comfort

• Check the caulking and weatherstripping around windows, doors, and siding for gaps.
• Check the garage door seals, and make sure the opener and moving parts are working before it’s minus twenty.
• If you have a gas fireplace or insert, get it serviced and confirm it lights properly.

Safety and supplies

• Test smoke detectors and replace the batteries.
• Get the shovel, roof rake, and ice scraper out of storage and check they’re usable.
• Buy ice melt and sand now. The first storm is a bad time to find out the store is sold out.
• Test exterior lighting. Winter evenings come early.
• Store or cover outdoor furniture and the BBQ.

If you’re travelling over the holidays

Don’t turn the heat way down while you’re away. A cold house with a burst pipe costs far more than the savings. Have someone check on the house, and know who you’d call if something happens while you’re gone.

One more thing

You don’t have to do all of it. If you only get to a few items right away, start with the first section. If you’re thinking about selling in the next year, a house that’s been looked after over the winters tells buyers something useful about how it’s been cared for.

Once the cold has settled in, the mid-winter home check-in covers the early warning signs worth watching for. And when spring arrives, there is a companion post on getting your home ready for Calgary’s rainy season.

If you have questions about any of this, or want suggestions on who to call, I’m happy to help.
