Preparing Your Calgary Home for Winter: A Contractor’s Checklist
Winter in Calgary is no joke. One day it’s a balmy chinook, the next it’s -30 with a windchill that’ll freeze your eyelashes off. Prepping your home now can save you a ton of headaches and expensive repairs down the line. I’ve seen firsthand the damage a burst pipe or an ice dam can do, and trust me, it’s not pretty – or cheap.
This isn’t about just putting on a sweater. This is about protecting your biggest investment from everything a Calgary winter can throw at it. From the deep freeze to the eventual spring thaw and potential flooding, there’s alot to consider.
Let’s get into it. Here’s my no-nonsense checklist for getting your Calgary home ready for the long haul.
The Roof: Your First Line of Defence
Your roof takes a beating in Calgary. Hail in summer, heavy snow in winter, and those wild temperature swings from chinooks can really stress it out.
Inspect for Damage (or Call a Pro)
- Look for missing or damaged shingles: After a hailstorm or a particularly windy week, go out and take a look. If you’re not comfortable on a ladder, grab some binoculars or call a local roofing company. Even a small missing shingle can let water in, leading to rot and costly repairs.
- Check flashing around vents and chimneys: These are common leak points. Make sure the sealant isn’t cracked or pulling away.
- Clean your eavestroughs: This is a big one. Clogged eavestroughs mean water can’t drain properly. When that water freezes, it expands, creating ice dams. Ice dams force meltwater *under* your shingles and into your attic and walls. I’ve seen kitchens in Altadore and bathrooms in Tuscany ruined by ice dams. Not fun.
- Consider heat tape: If you’ve had ice dam issues before, especially on north-facing slopes or over entryways, consider installing heat tape. It’s a small investment compared to structural water damage.
Expect to pay a few hundred dollars for a professional eavestrough cleaning and inspection, and potentially $1,000 – $3,000+ for minor roof repairs depending on the scope. A full re-shingle job can run $10,000 – $25,000+.
Exterior Walls & Foundation: Sealing the Envelope
Your home’s exterior is like a cozy winter coat. You want it sealed up tight.
Seal Up Cracks and Gaps
- Caulk around windows and doors: Over time, caulk shrinks and cracks. Grab a tube of exterior-grade caulking (silicone or urethane are good choices for our climate) and seal any gaps you see. This keeps out drafts and moisture.
- Check your siding: Make sure there are no loose panels or holes where critters might sneak in for winter. If you’ve got older vinyl siding, it can get brittle in the extreme cold. James Hardie fibre cement siding holds up much better, but it’s a bigger investment.
- Inspect your foundation: Look for cracks. Small hairline cracks might be fine, but anything larger than a quarter-inch or showing signs of active leaking needs attention. Water infiltration through your foundation can lead to really serious issues, especially with freeze-thaw cycles.
- Grade your landscaping: Make sure the ground around your foundation slopes *away* from your house. This directs meltwater away and prevents it from pooling against your foundation. This is critical for preventing basement leaks.
If you’re seeing persistent foundation issues, especially in older homes in areas like Bridgeland or Kensington, it’s worth getting a professional assessment. Minor crack repairs might be a few hundred bucks, but serious weeping tile or structural work can easily run into the tens of thousands.
Windows & Doors: Keep the Warmth In
Drafty windows and doors are like throwing money out the window. Literally.
Stop the Drafts
- Weatherstripping: Check the weatherstripping around all your exterior doors. If it’s cracked, compressed, or missing, replace it. It’s an easy DIY fix and makes a huge difference.
- Door sweeps: Make sure your door sweeps are making good contact with the threshold. If you can see light under the door, cold air is getting in.
- Window insulation film: For older, drafty windows that you’re not planning to replace yet, temporary insulation film kits can cut down on heat loss significantly. Not the prettiest, but effective.
- Consider window upgrades: If you’re still rocking single-pane windows or really old double-panes, winter is a harsh reminder of their inefficiency. New energy-efficient windows, especially triple-pane, can drastically reduce your heating bills. A full house of new windows in Calgary can run $15,000 – $40,000+, but they pay for themselves over time.
Plumbing: The Frozen Pipe Nightmare
This is where things can go wrong fast and cost you dearly. A burst pipe in a -30 cold snap is every homeowner’s worst nightmare. I’ve seen basements in Cranston and garages in McKenzie Towne flooded from frozen pipes.
Protect Your Water Lines
- Disconnect garden hoses: This is non-negotiable. Disconnect all hoses from exterior spigots.
- Drain exterior taps: Turn off the water supply to your outdoor taps (usually a valve inside, near where the pipe exits the house) and then open the exterior tap to drain any residual water. If you don’t have frost-free hose bibs, this is essential.
- Insulate exposed pipes: Check your garage, crawl spaces, and any unheated areas for exposed water pipes. Wrap them with foam pipe insulation (it’s cheap and easy to install).
- Know where your main water shut-off is: Seriously. If a pipe bursts, you need to know how to shut off the water *immediately*. Find it now, before you need it.
- Keep garage doors closed: If you have water lines running through your garage (e.g., for a laundry sink or even just the main line), keep that garage door closed, especially overnight or during extreme cold snaps. A little space heater can help if it’s consistently below freezing.
- Don’t turn off your heat completely: If you’re going away for a few days, resist the urge to turn your thermostat down to 10°C. Keep it at least 15°C (or warmer if pipes are in exterior walls) to prevent freezing, especially in older homes with less insulation.
Heating & Ventilation: Keeping Things Cozy and Safe
Your furnace is going to be working overtime. Give it some love.
Maintain Your HVAC System
- Change your furnace filter: Do this monthly during peak heating season. A clogged filter makes your furnace work harder, uses more energy, and reduces air quality.
- Get a furnace tune-up: An annual service by a qualified HVAC tech can catch small issues before they become big, expensive breakdowns. They’ll clean it, check components, and ensure it’s running efficiently and safely. Expect to pay $100 – $250 for a professional tune-up.
- Clear around outdoor vents: Make sure your furnace exhaust and fresh air intake vents are clear of snow and ice. Blocked vents can lead to carbon monoxide buildup or furnace shutdowns.
- Check your chimney: If you have a fireplace, get your chimney inspected and cleaned annually by a WETT-certified professional. Blockages can lead to chimney fires or carbon monoxide issues.
- Test smoke and CO detectors: Replace batteries if you haven’t recently. This is a non-negotiable safety item.
Yard & Landscaping: Beyond the House
Even your yard needs a bit of winter prep.
Protect Your Outdoor Space
- Winterize sprinklers: If you have an irrigation system, make sure it’s properly blown out and drained to prevent pipes from freezing and bursting. This usually costs $75 – $150.
- Store patio furniture: Protect your outdoor furniture from snow and ice damage.
- Trim tree branches: Cut back any branches that are close to your house or power lines. Heavy snow and ice can cause them to break and fall, causing damage.
- Clear pathways: Keep your sidewalks and driveways clear of snow and ice to prevent slips and falls. The City of Calgary has bylaws about clearing your sidewalks within 24 hours of a snowfall.
Planning for Bigger Renovations?
Winter can be a great time to plan for those bigger projects you’ve been dreaming about. While exterior work might be on hold during a deep freeze, it’s prime time for interior renovations. Think about that basement development in Signal Hill, or a kitchen reno in the Beltline.
You can get permits sorted with the City of Calgary’s myCity portal, finalize designs, and get materials ordered. When spring hits, you’ll be ready to go. A basement development in Calgary can run anywhere from $50,000 to $90,000+, and a kitchen reno from $40,000 to $80,000+. Getting a head start on planning now can make all the difference.
Don’t Wait Until It’s Too Late
Look, Calgary winters are beautiful, but they’re also tough on homes. Taking the time now to run through this checklist can save you a ton of stress, hassle, and money when the really cold weather hits. I’ve seen too many homeowners caught off guard when a surprise -35 cold snap or an early spring thaw brings problems they could have avoided.
If you’re not sure about something, or you’re seeing signs of a bigger issue, don’t hesitate to call in a professional. Sometimes a small repair now can prevent a major headache later.
If you’re thinking about tackling any of these tasks, or you’re looking at a larger project like a window upgrade or basement reno, feel free to reach out. Happy to chat through it with you and offer some insights.
