7 Fall Home Maintenance Tasks That Prevent Winter Damage and May Lower Your Insurance Costs

Water damage is the leading cause of home insurance claims in Canada, according to the Insurance Bureau of Canada, and insured severe weather damage across the country reached over $8 billion in 2024, according to the Insurance Bureau of Canada (IBC). Winnipeg's first hard freeze, meaning temperatures below -2°C, usually arrives in early to mid-October. Here are seven jobs, ordered from highest leverage down, that you can finish in a few weekends.

Water first

1. Sump pump

Pour a bucket of water into the pit and watch the pump start, lift, and shut off. Then price a battery backup. Pumps tend to fail during a power outage in a storm, which is exactly when you need them. Ask your insurer whether a backup unit changes your sewer backup coverage or premium, since some will adjust either one.

2. Outdoor taps

Disconnect hoses, shut the interior valve to each outdoor tap, and open the tap to drain it. Water left in the line freezes, expands, and splits the pipe inside the wall, where you won't see it until spring. Do this before the hard freeze, not after.

3. Gutters and downspouts

Clear the gutters by hand and run a hose to confirm water leaves the downspout. Clogged gutters cause ice damming, where meltwater refreezes under the shingles and pushes moisture into the attic or walls. Point downspouts several feet away from the foundation as well.

4. Overhanging branches

Cut back any branch that hangs over the roof or near the power line. Snow loads snap them, and a falling limb is a claim you caused by skipping a saw. Trees are entering dormancy now, which makes fall a good time to prune.

Heat, air, and fire

5. Weatherstripping

Run a lit incense stick around window and door frames and replace the weatherstripping wherever the smoke wobbles. Natural Resources Canada puts the potential energy savings from proper sealing at 15% to 20%, and Manitoba Hydro notes heating can be over 50% of a home's energy use. One caution: a tighter house needs a working HRV (heat recovery ventilator). Check its filter, or you may trade drafts for condensation and mould.

6. Furnace and chimney

Book a furnace inspection now, and a chimney sweep if you burn wood. A professional furnace visit in Manitoba runs roughly $95 to $250 for 2026, based on the research I pulled, and rates tend to climb once the first cold snap hits and everyone calls at once. The National Fire Protection Association recommends annual chimney cleaning because creosote buildup is a leading cause of house fires.

7. Smoke alarms

Flip each alarm over and read the manufacture date. Anything older than 10 years gets replaced, even if it still beeps on test. It's a $20 to $40 job, so a rough estimate is all I'll offer, and it takes ten minutes per floor.

Keep the paper trail

Insurers expect you to maintain the house. Most policies exclude gradual deterioration, so a roof that leaks because it was old and neglected is typically not covered, even under an "all-risk" policy. Many homeowners assume otherwise.

So document the work. Take dated photos of the cleaned gutters and the tested pump, and keep the receipts from the furnace tech and the chimney sweep. If you hire a bonded professional for gutters or roof checks instead of climbing the ladder yourself, you also get an invoice that shows due diligence if an adjuster ever asks.

One more thing insurers increasingly do: they assess roofs from satellite imagery. You can walk the perimeter with binoculars and look for missing, curled, or lifted shingles. Fix them before someone else spots them from space.

Nothing here guarantees a lower premium, and your insurer decides what discounts exist. But a claim-free record is still the most dependable way to keep premiums down, and every item above targets a claim that tends to be preventable.

Start with the sump pump. It takes five minutes.
