Get Ready for Winter: Doors & Windows

Introduction

When the temperature drops and the snow sets in around Montreal, your home’s doors and windows become even more critical. They’re not just architectural features — they’re the frontline of comfort, energy efficiency and weather protection. Studies show that about one-quarter of a home’s heat loss during colder months occurs through windows and doors when they are not properly sealed. A poorly sealed door or window can mean lost heat, rising energy bills and an uncomfortably chilly indoor environment.
By taking a few targeted maintenance steps now, you’ll keep your home warm, efficient and fully ready for the winter ahead.

1. Why winter preparation matters

• In cold-climate homes, exterior openings (windows, doors, garage doors) can account for a significant portion of heat loss; industry data suggest windows alone may contribute 25%–30% of heating energy loss in some cases.
• Drafts, moisture infiltration and worn weather-stripping don’t just raise your energy bill—they reduce comfort and shorten the lifespan of your fixtures.
• Acting ahead of the worst weather means fewer problems, better efficiency and more comfort for homeowners in the Montreal/West Island area.

2. Exterior door checklist

Inspect weather-stripping & seals

• With a closed door, slide a sheet of paper under the door sweep. If it slides out easily, your seal may be compromised.
• Replace missing or cracked weather-stripping so cold air doesn’t creep in.

Evaluate door fit & frame condition

• Does your door close smoothly and fully? Winter cold can shift frames slightly, creating gaps.
• Check the exterior trim caulking for cracks or shrinkage—these gaps let cold air and moisture in.

Lubricate hardware & hinges

• Apply lubricant to hinges, check locks engage cleanly and examine the threshold for damage.
• Snow and ice can build beneath the door threshold; make sure the door sweep is in good condition.

Consider insulation performance

• If your entry or patio door is older or showing signs of wear, consider upgrading to a high-efficiency model with improved insulation.
• Evaluating now can prevent discomfort later when the cold is at its worst.

3. Windows & frame maintenance

Check for air leaks / drafts

• On a cold day, run your hand around interior window frame edges—persistent cold spots suggest leaks.
• You can also hold a lit candle near the frame edge: if the flame flickers, air may be infiltrating.
• Because windows often represent one of the largest sources of heat loss in the building envelope, catching leaks early is important.

Inspect glazing & seals

• Look for condensation between panes in double or triple-glazing—this often means the seal is broken and insulation compromised.
• Examine frames: for wood, check rot; for PVC, check warping; for aluminum, look for signs of pitting or corrosion.

Clean and clear tracks, sills & drainage

• Remove debris (leaves, grit, old caulk) from window tracks, sills and drainage channels so water, snow-melt or ice don’t accumulate and damage the frame.
• Clean glass and frames with non-abrasive, non-acidic cleaners to maintain finish and longevity.

Lubricate moving parts & examine hardware

• Sliding windows, tilt or crank units should move easily. Lubricate and tighten loose parts as needed.
• Ensure seals and locks close tightly and evenly across the frame.

Re-caulk & reseal exterior trim

• Exterior caulking can dry or crack over time, creating invisible entry points for cold air. Inspect and re-caulk gaps of around 1-2 mm or more.
• A well-sealed window frame reduces both drafts and moisture intrusion.

4. Garage doors & large openings

If your home includes a garage or patio door, these large openings deserve attention too:

• Inspect the bottom seal and any side weather-seals for secure contact—gaps admit cold air and snow-melt.
• Lubricate rollers, tracks or hinges so snow, ice or winter debris won’t bind the mechanism.
• If your garage door has glass panels, check for frost misting or condensation—this may signal weak insulation and be worth upgrading.

5. Final checks & professional help

Indoor humidity control

• High indoor humidity plus cold outdoor surfaces may cause condensation, frost or even mold—a reason to pair maintenance with proper ventilation or de-humidification.
• Balancing humidity improves comfort and preserves the integrity of doors and windows.

Professional inspection benefit

• If you detect persistent drafts, condensation between panes, hardware failure or seal problems that DIY methods can’t fully address, consider calling in a professional.
• A qualified installer can recommend whether a repair or full replacement is best and tailor the solution for Quebec’s climate.

Timing matters

• The best time for inspection and maintenance is early fall—before extreme cold sets in.
• Early action reduces the risk of emergency repairs or discomfort during peak winter.
