How to Winterize Outdoor Spigots and Prevent Costly Freeze Damage

Western Slope winters can be beautiful—and brutal on plumbing. When temperatures dip in Montrose, Delta, Ouray, Ridgway, and Telluride, water left in outdoor spigot lines can freeze, expand, and burst pipes behind walls. A quick, November winterization prevents flooded basements, damaged drywall, and frustrating holiday interruptions. Here’s a friendly, step-by-step guide from West Plumbing, LLC to winterize outdoor spigots, prevent frozen faucets, and protect your home before the first deep freeze.

Why winterizing matters in high-elevation Colorado

At higher elevations, overnight lows drop fast, wind accelerates heat loss, and north-facing walls stay colder longer. That combination makes hose bibs and exterior lines especially vulnerable. If you’re hosting for Thanksgiving or heading out for ski season weekends, winterizing outdoor faucets now reduces the chance of a midwinter leak—and costly emergency plumbing repairs.

Step-by-step: How to winterize a standard hose bib

Follow these quick steps to winterize outdoor spigots and protect your pipes:

Disconnect garden hoses, splitters, and timers. Leaving them attached traps water and invites freeze damage.

Locate the interior shut-off valve for each spigot (often near the ceiling in a basement or crawl space). Turn it clockwise to close.

Open the exterior faucet fully to drain standing water. Leave it slightly open through winter.

If your interior shut-off has a small “bleed” cap, place a cup underneath, unscrew the cap, and drain any remaining water from the line. Replace the cap snugly.

Install an insulated faucet cover on the exterior spigot for added protection against wind and deep cold.

Check vacuum breakers/backflow preventers for cracks. Replace worn parts before temperatures plunge.

What temperature do outdoor faucets freeze?

Water freezes at 32°F, but most outdoor faucet lines are at risk of bursting when temperatures fall below about 20°F for several hours—especially on wind-exposed walls or uninsulated pipe runs. On the Western Slope, these conditions are common from late November through March. Wind chill doesn’t change water’s freezing point, but it does strip heat from surfaces faster, speeding the freeze inside thin, exterior pipes.

No interior shut-off? Your best options

Many older homes in Montrose and Delta don’t have a dedicated shut-off for each spigot. You still have choices to prevent freeze damage:

Upgrade to a frost-free spigot (freeze-proof sillcock) that drains itself when turned off correctly.

Add an interior ball valve on the supply line so you can isolate and drain the run each fall.

Insulate accessible pipe sections in basements or crawl spaces; seal air leaks around hose bib penetrations.

Use UL-listed heat cable with a GFCI outlet on problem lines as a short-term solution—installed carefully and per instructions. West Plumbing, LLC can install frost-free spigots, add shut-off valves, and reroute lines for better cold protection.

Signs it’s time for repair or replacement

Persistent dripping at the spout or from the vacuum breaker

Water stains or musty smells indoors when the exterior spigot is opened

Low flow or pulsing at the spigot after a hard freeze

Difficulty turning the handle, grinding, or visible corrosion

A split or bulge on the pipe, especially near fittings

Vacation homes and rentals: extra protection tips

If you manage a rental in Ouray, Ridgway, or Telluride—or leave a second home empty—set the thermostat to at least 55°F, shut off and drain exterior spigot lines, and consider smart leak detectors near vulnerable areas. If power outages are common, a proactive winterization plus a frost-free spigot is your best first line of defense.

What not to do

Don’t leave hoses attached “just one more week”—a sudden cold snap can burst pipes overnight. Avoid pouring automotive antifreeze down exterior lines; it’s toxic and not designed for residential plumbing. Skip unvented space heaters in crawl spaces; they’re a fire and carbon monoxide hazard.
