How to Prevent Frozen Pipes in Colorado

Updated · Kestrel editorial

Short answerBefore a sub-zero night, disconnect hoses, confirm sprinklers are blown out, open cabinet doors on outside walls, keep the heat at least in the mid-50s even when away, and let vulnerable faucets drip. Insulate crawlspace and garage pipes and seal drafts.

Where pipes freeze first

  • Exterior walls, especially kitchens and bathrooms
  • Crawlspaces and unheated basements
  • Garages and attics
  • Hose bibs and sprinkler backflow devices
  • Pipes near dryer vents or rim joists with drafts

Before a cold snap

  • Disconnect garden hoses
  • Blow out and drain irrigation systems in fall
  • Open cabinet doors on outside walls
  • Drip faucets on the coldest runs
  • Keep the thermostat up, even when traveling

If a pipe freezes

Warm it gently with a hair dryer or space heater at a safe distance. Never use an open flame. If you see a split, shut off the main first.

Permanent fixes

Rerouting pipes out of exterior walls, insulating, air-sealing and installing frost-free sillcocks. See frozen pipe repair.

Fixes for pipes that freeze every year

If the same line freezes whenever temperatures drop well below zero, reroute or insulate it for good: frost-free sillcocks sloped to drain, insulation and air sealing where the line crosses a rim joist, or heat cable on exposed crawl-space pipes.

How to Prevent Frozen Pipes in Colorado: follow-up questions

Should I drip faucets during a Colorado cold snap?

Yes, on nights well below freezing, a slow drip from faucets on exterior walls keeps water moving and relieves pressure.

Do frost-free spigots still freeze?

They can if a hose is left connected, which traps water in the valve. Disconnect hoses before the first hard freeze.
