typical January low ~54°F
moderate risk

Moderate freeze risk — protect exposed pipes before cold snaps.

  • Know where your main water shut-off valve is, so you can stop the water fast if a pipe bursts.
  • Before the first hard freeze, disconnect and drain garden hoses and cover outdoor hose bibs (spigots).
  • Insulate pipes in unheated areas — crawl spaces, garages, attics, and along exterior walls.
  • On nights below freezing, let a faucet drip slightly and open cabinet doors so warm air reaches the pipes.

An informational risk estimate from local winter climate normals — not a forecast or a guarantee. Steps are general guidance; call a local plumber for at-risk plumbing.

This is a risk estimate only, not a diagnosis — every home is different, and a local pro can check your specific risk.

How freeze risk works

The freezing threshold

Water lines are at risk when temperatures stay below about 20°F, and uninsulated pipes in unheated or exterior spaces freeze first. Colder local winters raise the baseline risk.

Why exposure matters

Pipes in crawl spaces, attics, garages, and along exterior walls lose heat fastest, so where a line runs matters as much as how cold it gets. The checker combines both into a risk level and prevention steps.
