A Winnipeg seasonal home maintenance checklist, from a contractor

By Pavel StreltsovPublished June 5, 20262 min read

In short

Winnipeg is hard on houses: deep frost, clay soil, big freeze-thaw swings. A little seasonal upkeep prevents the expensive surprises. Here's the short list that matters most, fall and spring.

Part of What a contractor's eye looks for when buying a Winnipeg home

Winnipeg is genuinely hard on houses. Deep frost, clay soil that swells and shrinks, and freeze-thaw swings that work at every joint and seam. The upside is that most of the expensive problems I see are preventable with a little seasonal upkeep — the kind I learned doing the work, not reading about it.

Here's the short version of what actually matters. (There's a fuller seasonal checklist in my resources, and it doubles as a companion to the Seller's Guide.)

Before winter

  • Drain and shut off exterior hose bibs. Disconnect hoses, close the interior shut-off valve, and open the outdoor faucet so trapped water can't freeze and burst the pipe. This is the cheapest disaster you'll ever prevent.
  • Test the sump pump and its backup. Pour water into the pit and confirm it runs. Check the battery backup — this is your insurance against a flooded basement.
  • Direct water away from the house. Clear the gutters before freeze-up and extend downspouts well past the foundation. Most basement trouble starts here.
  • Service the furnace and check the CO detector. A dying furnace always seems to quit on the coldest night.
  • Look at the roof and attic. Check shingles and flashing before the snow flies, and make sure attic insulation and ventilation are doing their job so you don't get ice dams.

Before summer

  • Test the sump pump again — before the spring melt. This is Winnipeg's number-one basement risk, and the melt is when it gets tested for real.
  • Check the foundation after the thaw. Walk the basement and the exterior for new cracks or heaving. Clay soil moves a lot over a winter.
  • Confirm the grade still slopes away. Frost heave shifts things. Make sure the ground around the foundation still pushes water out, not in.
  • Reconnect and check exterior faucets for any freeze damage that happened over winter.
  • Service the A/C and clean the dryer vent. One's comfort, the other's fire safety.

Why this list, and not a longer one

Plenty of checklists run to fifty items. These are the ones that, left undone, turn into the repairs I see cost Winnipeg homeowners the most — water in the basement, burst pipes, ice dams, and foundation movement. Stay ahead of those and you've handled the big risks of owning a home in this climate.

If you're thinking of selling, this same upkeep is what keeps small things from becoming negotiation leverage for a buyer. And if you're buying, it's a preview of the questions worth asking about any home you tour.

Frequently asked questions

What's the single most important maintenance task in Winnipeg?

Testing your sump pump — and having a battery backup. A spring melt or heavy summer storm with a dead pump is the fastest route to a flooded basement here. Test it twice a year by pouring water into the pit and confirming it kicks on.

Why do hose bibs matter so much?

If you leave a hose connected or don't drain the line before our first hard freeze, trapped water expands and can burst the pipe inside your wall — and you often don't find out until spring when you turn the water back on and it pours into the basement.

Most buyers fall for the finishes. I look past them at the bones — foundation, roof, mechanicals, and how water moves around the house. Here's the order I check things in, and what should make you pause before you write an offer.
