Colorado weather has a way of skipping the polite transition from fall to winter. One afternoon you’re cleaning up leaves. The next morning, the hose is frozen to the spigot and the snow shovel is buried behind the lawn chairs.
Quick Check: Do These First
Short on time? Start here:
- Disconnect every garden hose.
- Winterize the sprinkler system.
- Protect exposed pipes and outdoor faucets.
- Check the furnace filter.
- Put the snow shovel and ice melt where you can reach them.
Colorado winter prep doesn’t have to take all weekend. Start with water, heat, and a safe path out the door.

1. Disconnect Hoses and Protect Outdoor Faucets
Start your Colorado frost prep outside. A connected hose can trap water in the faucet and pipe. When that water freezes and expands, it can lead to a leak or burst pipe.
Walk around the house and:
- Disconnect, drain, and store every garden hose.
- Drain hose reels and watering tools.
- Check outdoor faucets for drips.
- Add an insulated faucet cover where needed.
- Seal obvious gaps where pipes enter exterior walls.
If a faucet leaks after it is shut off, fix it before a hard freeze. A slow drip is still water in the wrong place.
2. Winterize Your Sprinkler System
Sprinkler lines and backflow components can hold water even after regular watering ends. That leftover water can freeze and damage the system.
The right process depends on how your irrigation system was built. It may include shutting off the water, draining exposed components, insulating the backflow preventer, or having the lines professionally blown out.
If you’re not sure how your system drains, check the manufacturer’s directions or call an irrigation professional. Compressed-air blowouts require the right pressure and equipment.
Timing matters, too. At our Summit County store, freezing nights tend to demand attention earlier. Neighbors near Golden and Green Mountain may have a little more time, but an early Front Range cold snap can close that window quickly.

3. Protect Vulnerable Pipes
Check plumbing in unheated or drafty spaces, including garages, crawl spaces, cabinets on exterior walls, and unfinished basements.
Look for:
- Bare pipes exposed to cold air
- Old or damaged pipe insulation
- Gaps that let outside air reach plumbing
- Pipes that have frozen before
Foam pipe insulation is enough for many straightforward areas. A pipe that repeatedly freezes may need a different solution.
Not sure what you are looking at? Take a clear photo of the pipe and note its material, diameter, and location. Bring that information to your local Colorado Ace. Our team can help you compare options without guessing.
4. Check the Furnace Filter and Heating System
Your heating system is about to work a lot harder. Give it a quick check before the first truly cold week.
Start with the furnace filter. Check it monthly during heating season and replace it when it looks dirty or according to the filter and system instructions. The right size matters. Bring the old filter or take a photo of the dimensions before you shop.
Then turn on the heat before you urgently need it. Pay attention to:
- Unusual smells that do not clear quickly
- New rattling, squealing, or banging sounds
- Weak airflow
- Rooms that do not warm evenly
- A system that cycles on and off repeatedly
If something seems wrong, call a qualified HVAC professional. It is better to schedule service now than during the first long cold stretch.
5. Stop the Most Obvious Drafts
You do not need a full energy audit to find the worst drafts. On a cool or windy day, check around exterior doors, older windows, attic access points, and penetrations for pipes or wiring.
Depending on the gap, the fix may be as simple as:
- Replacing worn door weatherstripping
- Adding a door sweep
- Applying removable window caulk
- Sealing small exterior gaps with the correct caulk
Use products made for the surface and location. If you are unsure whether a gap needs caulk, foam, or weatherstripping, take a photo and measurements. That will help a Colorado Ace team member point you toward the right option.
6. Test Smoke and Carbon Monoxide Alarms
Homes are sealed tighter in winter, and heating equipment runs more often. Take a few minutes to test every smoke and carbon monoxide alarm.
- Press the test button on each alarm.
- Replace batteries if needed.
- Check the manufacture date and replacement guidance on the unit.
- Make sure alarms have not been painted over, covered, or blocked.
If an alarm chirps, do not just remove the battery. Find out whether it needs a new battery or has reached the end of its service life.
7. Clear Gutters and Look Up From the Ground
Leaves and pine needles can block gutters and downspouts. That makes it harder for melting snow to drain away from the roof and foundation.
Before surfaces get icy:
- Clear leaves and debris from gutters you can reach safely.
- Confirm downspouts direct water away from the house.
- Look for loose gutters or visible roof damage.
- Check for branches hanging over the roof, driveway, or walkway.
Do not climb onto a frosty or snow-covered roof. If the work requires a steep ladder, roof access, or branch removal near power lines, call a professional.

8. Put Snow and Ice Tools Within Reach
The best snow shovel in the world is not very helpful behind the patio furniture.
Move your winter tools to the front of the garage or shed now. At minimum, most homes need:
- A snow shovel that feels comfortable to lift
- Ice melt suited to the surface and household
- Warm, grippy gloves
- A sturdy push broom for light, dry snow
- An ice scraper and snow brush in each vehicle
Read the ice melt label before buying. Products differ in how they affect concrete, metal, plants, and pets. More is not always better. Follow the package directions and sweep up excess product when conditions allow.
If you use a snow blower, start it before the first storm. Check the manual, fuel or battery, shear pins, scraper bar, and other wear items. If the machine needs service, you will be glad you found out on a dry afternoon.
9. Build a Simple Storm Shelf
You do not need to turn the basement into a bunker. Keep a small group of useful supplies together so you are not searching for them during an outage or icy evening.
Consider:
- Flashlights and fresh batteries
- A battery-powered radio or charged power bank
- Basic first-aid supplies
- A few easy meals and drinking water
- Pet food and medications
- A printed list of important phone numbers
Check the car, too. A blanket, gloves, scraper, small shovel, water, and phone charger make a practical cold-weather kit.
A Local Tip for Colorado Homes
The same checklist applies across our three communities, but the timing does not.
- Summit County: Complete freeze-sensitive outdoor work first. Snow and sustained cold often arrive earlier at elevation.
- Golden and Green Mountain: Watch overnight lows, not just the daytime forecast. A warm afternoon does not rule out a freezing night.
- Mountain homes and cabins: Prepare before you leave. A small leak or heating problem can become a large repair when no one is there to catch it.
The practical rule is simple: if the forecast is making you think about winterizing, it is time to do it.

Frequently Asked Questions
When should I winterize my Colorado home?
Finish freeze-sensitive jobs before overnight temperatures regularly reach freezing. Summit County homeowners generally need to act earlier than homeowners in Golden or Lakewood. Watch your local forecast instead of relying on one statewide date.
What should I do first before a hard freeze?
Disconnect garden hoses, protect outdoor faucets and exposed pipes, winterize sprinklers, and make sure the heating system works. These jobs address the areas most likely to cause damage or immediate trouble.
Is heat tape safe for pipes?
Listed pipe heating cable can be useful when it is approved for the pipe and installed exactly as directed. Requirements vary by product. Never improvise, overlap cable unless allowed, or use damaged cable. Ask a qualified professional for help if the application is unclear.
How often should I replace my furnace filter in winter?
Check it monthly during heating season and follow the filter and HVAC system instructions. Replace it when it is dirty or reaches the manufacturer’s recommended service interval.
