As the leaves begin to fall and temperatures start to dip, it’s time to start thinking about preparing your home for the Canadian winter ahead. Taking the time to winterize your home can go a long way in saving money, preventing surprise repairs, and keeping your living space warm and comfortable throughout the colder months.

Here’s why winter prep makes a difference

Save money on heating and energy bills
Avoid unexpected (and expensive) repairs caused by cold-weather damage
Protect your home’s value with regular upkeep
Create a more comfortable and cozy space for you and your family

When to start: Fall is the perfect time

The best time to start prepping your home for winter is during the fall, before the snow starts flying and the temperature really drops. This gives you plenty of time to tackle important tasks without rushing and ensures your home is ready when the cold weather hits.

Let’s get into a few simple and practical ways you can prep your home for those cold Canadian winters!

8 practical tips to weatherproof your space

1. Seal gaps around doors and windows

Cold air can easily seep into your home through small cracks and gaps around windows and doors, making it harder to keep warm.

What to do:

Use caulking to seal cracks around window frames
Apply weatherstripping to doors to stop drafts
Install door sweeps at the bottom of exterior doors
Consider using thermal curtains or window insulation film for extra protection

Homeowner benefits: By sealing any gaps around your windows and doors, you’ll stop heat from escaping, which helps your home stay warmer and reduces strain on your heating system, lowering your utility bills.

2. Clean gutters and downspouts

Leaves and debris can block water flow, leading to ice dams and water damage when snow begins to melt and refreeze.

What to do:

Remove leaves, twigs, and buildup from gutters
Ensure downspouts direct water away from your home’s foundation
Consider installing gutter guards to prevent future clogs

Homeowner benefits: Blocked gutters can lead to leaks, mould growth, and damage to your roof, siding, and foundation — all expensive repairs that are easily avoided with a bit of maintenance.

3. Service your furnace or heating system

A well-functioning furnace is essential for a safe, warm winter. Servicing it before temperatures drop ensures efficiency and reduces the risk of a breakdown.

What to do:

Schedule a professional inspection and cleaning of your furnace or boiler
Replace or clean furnace filters regularly (monthly during peak use)
Check that vents and registers are unobstructed and clean

Homeowner benefits: Routine maintenance helps extend the life of your heating system and improves efficiency saving you money on energy costs.

4. Drain and disconnect outdoor faucets and hoses

Water left in exterior pipes can freeze and expand, leading to burst pipes and flooding inside your home.

What to do:

Disconnect and store garden hoses
Shut off the water supply to outdoor taps (from the inside if possible)
Drain any remaining water from the faucet and install insulated covers

Homeowner benefits: This simple step can prevent potential water damage from frozen or burst pipes that may result in flooding and expensive repairs.

5. Add or upgrade insulation

Even though you can’t see it, insulation plays a huge role in making sure your home stays warm and cozy. Proper insulation is key to maintaining indoor heat and reducing energy usage.

What to do:

Check your attic, basement, and crawl spaces for adequate insulation
Add insulation where needed — especially in older homes
Use pipe insulation to protect plumbing in colder areas of your home

Homeowner benefits: A well-insulated home stays warmer in winter and cooler in summer, improving energy efficiency and home comfort all year round.

6. Inspect your roof and attic

Your roof is your home’s first line of defense against snow, ice, and freezing rain. Maintaining it will help ensure the harsh winter elements don’t make their way inside.

What to do:

Look for missing, loose, or damaged shingles
Check flashing around vents and chimneys for cracks
In the attic, ensure there’s proper insulation and ventilation to prevent ice dams

Homeowner benefits: Addressing roof issues early helps avoid costly leaks, structural damage, and insulation problems during heavy winter storms.

7. Test smoke and carbon monoxide detectors

With furnaces, fireplaces, and space heaters running more often in winter, the risk of fire or carbon monoxide poisoning increases.

What to do:

Test all smoke and CO detectors in your home
Replace batteries and units that are more than 10 years old
Install detectors near bedrooms and fuel-burning appliances

Homeowner benefits: Functioning detectors can save lives — and testing them only takes a few minutes.

8. Stock up on winter essentials

If a winter storm hits, being prepared can make a big difference in your comfort and safety.

What to do:

Keep sidewalk salt or sand on hand to prevent slips
Check your snow shovel or snow blower is in working order
Create an emergency kit with flashlights, batteries, blankets, bottled water, and non-perishable food

Homeowner benefits: Being prepared reduces stress and helps you stay safe during power outages or extreme weather events.
