How to Prevent Frozen Pipes in Brighton, Colorado (2026 Plumber Checklist)
Last updated: 2026-05-11. Written by the crew at Brantley & Sons Plumbers LLC, a licensed and insured Colorado plumbing contractor based in Brighton, 80603.
Quick answer. In Brighton, frozen pipes usually come from three places: an exterior hose bib that was never disconnected, an uninsulated copper or PEX run in a basement rim joist, and a vacant home where the heat was set too low. Prevent them by disconnecting every hose in October, insulating exposed runs, keeping thermostats at or above 58 degrees F when away, and letting cabinet doors open on the coldest nights. If a pipe already froze, shut off the main and call us at

Brighton winters are not the coldest on record, but they cycle. A 55 degree Tuesday turns into an 8 degree Thursday and a 42 degree Saturday. That on off pattern is what kills plumbing. A pipe that is right on the edge of freezing gets caught when the wind shifts and the north wall of the garage drops ten degrees faster than the rest of the house.
We run the same prevention checklist with every homeowner we meet in October. It takes less than an afternoon and it is the reason we do not hear from those customers again until the water heater needs swapping in 2031.
The high risk pipes in a Brighton house
- Exterior hose bibs, especially the one on the north or east wall that sees less sun.
- Supply lines in unheated crawl spaces.
- Rim joist runs in the basement, inches from the cold band board.
- Garage walls behind a water heater or utility sink.
- Under kitchen sinks on exterior walls, particularly in older bungalows near Bridge Street.
- Ice maker lines run through outside walls to the fridge.
- Sprinkler systems left with water in the backflow.
The October checklist
- Disconnect every hose. Every one. The one behind the fence, the one at the shed. A hose left connected traps water inside the bib and creates a freeze bomb.
- Shut off the interior valve to each hose bib if you have one, and then open the hose bib outside to drain the line.
- Blow out the sprinkler system and shut the backflow. If you do not have a compressor, this is worth a 40 dollar service call to a lawn company.
- Insulate exposed pipes in crawl spaces, garage walls, rim joists. Pre slit closed cell foam sleeves are 2 dollars per 6 foot section at any hardware store. Miter the corners.
- Cover backflow assemblies above ground (sprinkler backflows especially) with an insulated pouch.
- Service your water heater. A flushed tank heats faster and keeps the utility room warmer, which keeps nearby pipes warmer. See water heater repair.
- Set a winter thermostat minimum. Never go below 58 degrees F inside, even when traveling. Open cabinet doors under kitchen and bath sinks on exterior walls.
- Know where the main shutoff is. Usually basement front wall or crawl space access. Label it. Show anyone who lives in the house.
What to do at 10 below zero
Two mornings a winter in Brighton, the thermometer is in the single digits or below. On those days:
- Let a pencil thin trickle run at the faucet farthest from your main shutoff.
- Open kitchen and bathroom cabinet doors to let warm air reach pipes on exterior walls.
- Keep the garage door closed even if it is attached to the house.
- Do not lower the thermostat below 62 degrees F overnight.
- If you own a property in Bromley Park or Brighton Crossing where the basement is finished, check under the stairs and in the utility closet once per day.
Vacant and vacation homes. If you are leaving Brighton for more than 48 hours in winter, either keep the heat at 58 or higher and open interior doors, or fully winterize (shut main, drain system, add antifreeze to traps). Anything between those two is risky.
If a pipe already froze
Take a breath. Frozen is recoverable. Burst and leaking is the problem.
- Open the faucet fed by the suspect frozen line. If water trickles or nothing comes out, you probably have a freeze.
- Shut off the main water valve. If the pipe is already split you have bought yourself time.
- Warm the pipe slowly with a hair dryer or space heater. Never use an open flame. Start near the faucet and work toward the cold area.
- Watch for running water inside walls. Any sound of water where none should be means call a plumber right now.
- If you cannot reach the frozen area or you see any sign of a split, call 720 664 0815. We dispatch 24/7.
Frequently asked questions
Do frost free hose bibs really prevent frozen bursts?
Yes, when installed right. The valve seat sits several inches deep inside the heated envelope of the house, so the water that freezes outside the valve has nowhere to expand inside a closed pipe. They still need the hose disconnected because a connected hose traps water on the wrong side of the seat.
How much does a burst pipe repair cost in Brighton?
Exposed section repair runs 285 to 620 dollars. Behind drywall runs 450 to 1,150. Detail is on our pipe repair page.
Will homeowners insurance cover it?
Most Colorado homeowner policies cover sudden water damage from a burst pipe but not the pipe itself. Long slow leaks often are not covered. We document everything to help your claim.
Is it worth adding heat tape?
In specific cases, yes, especially for a run in a crawl space that cannot be reliably insulated. UL listed self regulating heat tape plugged into a GFCI, inspected each fall. We install it where it makes sense.
