Winter Home Maintenance Checklist: Stay Warm and Safe

Winter maintenance is less about projects and more about vigilance: protecting pipes from freezing, keeping heating systems safe and efficient, and watching for the problems cold weather creates. If you completed the fall checklist, you're already most of the way there.

Freeze protection (the top priority)

• Don't let the thermostat drop too low, even when you're away — keep it warm enough to protect pipes in walls and unheated spaces.
• During hard freezes, let faucets on exterior walls drip and open cabinet doors so warm air reaches the plumbing. See plumbing.
• Know your main water shutoff so you can act fast if a pipe does burst.

Heating safety and efficiency

• Test smoke and CO alarms. You're running furnaces and spending more time indoors — this is when CO risk peaks. See smoke & CO.
• Change the HVAC filter so the heating system isn't straining against a clogged filter. See HVAC.
• Keep heating vents and registers clear of furniture and rugs.

Watch the roof and gutters

• Watch for ice dams — ridges of ice at the roof edge that force meltwater under shingles. Clearing gutters in fall is the best prevention. See roof & gutters.
• Safely clear heavy snow from low or vulnerable roof areas if it accumulates dangerously.

Comfort tweaks

• Reverse ceiling fans to clockwise to circulate warm air.
• Add weatherstripping or door sweeps where you feel drafts.
