Winterizing Your Home: The Pre-Freezing Checklist That Prevents Burst Pipes

Winter damage is almost always preventable with an afternoon of work in the fall. This is the sequence that stops the expensive failures: frozen pipes, ice dams, a furnace that quits on the coldest night.

Water outside

Drain and shut off irrigation

Blow out or drain the system, then close the indoor valve and open the bleed. Left water in a line is a cracked manifold in January.

Disconnect and insulate spigots

Remove hoses, shut the interior shut-off, open the spigot to drain, then fit a foam cover. Frost-free spigots still fail if a hose is left connected.

Water inside

Know your main shut-off

Everyone in the house should find it in under 30 seconds. Tag it with a note.

Add heat to at-risk pipes

Pipes in exterior walls, crawl spaces and garage walls are the ones that burst. Foam sleeves help; a strand of heat tape on the truly exposed runs is worth it.

Roof and gutters

Clear gutters before ice

Clogged gutters hold water that freezes into an ice dam, pushing melt under shingles. Clean them and check that downspouts drain several feet out.

Check the attic on a cold day

Snow that melts and refreezes signals a warm, poorly insulated attic. Air-seal the hatch and add depth over the ceiling.

Heat and safety

Change the furnace filter and test early

Run the heat before you need it, listen for irregular noise, and book a technician while they are still available.

Test detectors and a carbon-monoxide alarm

Combustion appliances fire up in winter; a dead CO alarm is a real hazard.

Around the house

Weatherstrip doors, reverse ceiling fans to push warm air down, and keep interior doors open during a cold snap so heat reaches pipe-filled cabinets. A drip on the coldest nights is cheap insurance against a burst.

The 30-minute priority version

If you only do three: drain the irrigation, cover the spigots, and change the furnace filter. Those prevent the most common and most costly winter calls.
