Winter home maintenance checklist: what to watch when it's cold

Winter is for watching, not for big projects. If you did the fall work, the house is ready, and your job now is to keep an eye on the handful of things the cold actually threatens. The winter list is short on purpose. It is about catching trouble early, when it is still a small fix instead of a flooded basement.

Here is the winter home maintenance checklist.

Watch for ice

Ice is winter’s quiet, expensive problem.

Look for ice dams forming along the roof edge and gutters after snow.
Keep an eye on icicles, which often signal heat escaping into the attic.
Gently clear heavy snow from the roof if it builds up, or have a pro do it.
Keep walkways and steps clear and salted so no one gets hurt.

Prevent frozen pipes

A burst pipe is the disaster that defines a bad winter. A little attention prevents it.

On the coldest nights, let a faucet drip and open cabinet doors so warm air reaches the pipes.
Keep the heat no lower than 55 degrees, even when you are away.
Know where your main water shutoff is, so you can stop a burst pipe fast.
Watch unheated spaces like the garage, basement, and crawl space.

Manage humidity and air

A closed-up, heated house gets dry, then sometimes too damp in the wrong spots.

Run a humidifier if the air is dry enough to crack wood and skin.
Watch windows for condensation, which can lead to mold on sills and frames.
Check the bathroom and kitchen fans are clearing moisture.

Safety comes first in winter

You spend more time inside with the heat on, so this matters most now.

Test carbon monoxide detectors, the single most important winter safety check.
Test smoke detectors too, with more cooking and heating going on.
Never run a generator, grill, or car in the garage or any enclosed space.
Keep heat sources clear of anything that can burn.

Good indoor jobs for a cold weekend

When you are stuck inside anyway, get ahead on the indoor work.

Deep clean and declutter, one room at a time.
Organize your home records, manuals, and warranties.
Plan and budget the spring and summer projects you spotted last year.
Check caulk and grout in bathrooms and reseal where it has failed.

The short version

If you only watch four things this winter, watch these: ice dams, frozen pipes, carbon monoxide, and humidity on the windows. Those are the problems that do real damage while everything else can wait for spring.

Keep the watch easy

HomeAlmanac keeps the short winter list in front of you and reminds you to test the carbon monoxide detectors when it counts. And those quiet indoor weekends are the perfect time to get every manual and warranty into one searchable place, so the rest of the year runs smoother.

Winter asks less of your house than any other season. Watch the few things that matter, and let the rest wait for the thaw.
