When the Forecast Turns Frigid in Northern Colorado
Northern Colorado weather can change in a hurry. A sunny 50 degree afternoon in Fort Collins or Loveland can turn into single digits by morning, and that sudden swing is when homes tend to run into trouble. When the National Weather Service office in Boulder issues a freeze warning, it’s a good cue to spend a few minutes getting your house ready.
Brothers Plumbing, Heating & Electric has been helping Colorado families through cold snaps since 1980. Below, our team explains what a freeze warning means for your home, where problems usually start, and the simple steps that keep your family warm and your water flowing.
What Does a Freeze Warning Actually Mean?
Forecasters issue a freeze warning when temperatures are expected to fall to 32°F or below. A hard freeze warning means readings could drop to 28°F or colder for several hours, which is cold enough to freeze water in exposed plumbing.
Here’s why that matters. Water expands by roughly 9 percent as it turns to ice, and inside a pipe that expansion builds pressure between the ice and a closed faucet. That’s why a pipe often splits in a section that doesn’t even look frozen. A single burst pipe can release hundreds of gallons of water before anyone notices.
Which Parts of Your Home Are Most at Risk?
Some areas of a home get far colder than the rest. If any of these describe your house, give them extra attention when the forecast dips.
- Pipes in exterior walls, especially behind kitchen and bathroom sinks
- Crawl spaces and unfinished basements with little or no heat
- Attached garages where water lines run along the walls or ceiling
- Attics in homes with upstairs bathrooms or older plumbing layouts
- Outdoor spigots and hose bibs that still have hoses connected
- Sprinkler systems and backflow preventers that haven’t been winterized
How to Protect Your Pipes Before the Temperature Drops
The good news is that most freeze damage is preventable. A little prep the afternoon before a cold night goes a long way, and none of it requires special tools.
Outdoor Prep Checklist
- Disconnect, drain and store garden hoses so water can’t back up into the spigot
- Shut off the indoor valve for outdoor faucets if you have one, then open the spigot to let it drain
- Add insulated faucet covers to hose bibs for an inexpensive layer of protection
- Have your irrigation system blown out before the first hard freeze of the season
Indoor Prep Checklist
- Open cabinet doors under sinks on outside walls so warm air can reach the pipes
- Let faucets on vulnerable lines drip slowly overnight to keep water moving
- Keep your thermostat at 55°F or higher, even if you’re traveling
- Wrap exposed pipes in garages and crawl spaces with foam pipe insulation
- Keep the garage door closed whenever water lines run through it
- Find your main water shutoff valve now so you can reach it fast in an emergency
That last item is easy to overlook. Most Northern Colorado homes have the main shutoff in the basement, a utility room or near the water heater. Make sure every adult in the house knows where it is and how to turn it.
Signs Your Pipes May Already Be Frozen
Sometimes a pipe freezes despite your best efforts. Catching it early gives you a chance to thaw it before it cracks.
- A faucet that produces only a trickle or no water at all
- Frost or condensation on a visible section of pipe
- Unusual smells coming up from a drain
- Damp spots, bulges or stains on walls and ceilings near plumbing
If you notice any of these, our guide to frozen water pipes covers what’s happening behind the wall and when it’s time to bring in a licensed plumber.
Safe Ways to Thaw a Frozen Pipe
If you can see the frozen section and there’s no sign of a leak, you may be able to thaw it yourself. Work slowly and keep safety first.
- Open the faucet the pipe feeds so melting water and pressure have somewhere to go
- Warm the pipe gently with a hair dryer, heating pad or warm towels
- Start near the faucet and work back toward the frozen area
- Keep any space heater at a safe distance and never leave it unattended
Never use a torch, open flame or propane heater to thaw a pipe. These can damage the pipe, ignite nearby materials and create a carbon monoxide risk. If the frozen spot is hidden inside a wall or you can’t find it, give us a call instead.
Don’t Forget About Your Heating System
Your furnace or boiler is your home’s first defense against frozen pipes. If it struggles during a cold snap, every water line in the house becomes more vulnerable. Scheduling heating service before winter settles in helps you avoid a no-heat call on the coldest night of the year.
- Replace your furnace filter so air moves freely through the system
- Test your thermostat and swap in fresh batteries if it uses them
- Clear furniture and rugs away from vents and return grilles
- Test your carbon monoxide detectors on every level of the home

Electrical Safety During a Cold Snap
Freezing nights mean more space heaters, heat tape and extension cords, and that extra load can strain older circuits. A few precautions keep your family safe while the heat stays on.
- Plug space heaters directly into a wall outlet rather than a power strip
- Keep heaters at least three feet from bedding, curtains and furniture
- Watch for breakers that trip repeatedly, which can signal an overloaded circuit
- Check heat tape on pipes for cracks, fraying or scorch marks before using it
If outlets feel warm or lights flicker when a heater kicks on, our licensed electrical team can take a look and make sure everything is safe.
What to Do If a Pipe Bursts
A burst pipe is stressful, but acting quickly limits the damage. Follow these steps in order.
- Turn off the main water shutoff valve right away
- Shut off power to any area where water is near outlets, fixtures or appliances
- Open nearby faucets to drain remaining water from the lines
- Call a licensed plumber, then take photos of the damage for your insurance records

At what temperature do pipes freeze in a house?
Pipes can start to freeze once outdoor temperatures stay at or below 20°F for several hours, especially lines in exterior walls, garages or crawl spaces. Wind and poor insulation can raise that risk even at slightly warmer temperatures.
Should I let my faucets drip during a freeze warning?
Yes, a slow drip on faucets connected to vulnerable pipes helps relieve pressure and keeps water moving. Focus on sinks along exterior walls instead of running every faucet in the house.
What temperature should I keep my house at when I’m away in winter?
Keep your thermostat at 55°F or higher while you’re gone. It’s also smart to have someone check on the house during long trips and to shut off the main water valve if you’ll be away for an extended time.
How do I know if a frozen pipe has burst?
Look for water stains, bulging drywall, puddles or the sound of running water when no fixtures are on. A sudden drop in water pressure or a spike in your water bill can also point to a hidden leak.
Can I use a space heater to thaw a frozen pipe?
A space heater can help warm the area around an exposed pipe, but it should never be left unattended or placed near anything flammable. Never use an open flame, torch or propane heater on plumbing.
Do I need to winterize my sprinkler system in Northern Colorado?
Yes. Water left in irrigation lines and backflow preventers can freeze and crack components, leading to costly spring repairs. Plan to have the system blown out before the first hard freeze.
Does homeowners insurance cover burst pipes?
Many policies cover sudden and accidental pipe bursts, but coverage often depends on whether reasonable steps were taken to prevent freezing. Check your specific policy and take photos of any damage right away.
Can Brothers help with frozen pipes after hours or on weekends?
Yes. We offer service seven days a week with No Overtime Charges, so you won’t pay extra when a cold snap hits on a Saturday. Call (303) 468-2294 to schedule help from our team.
