Fall moves fast on the Front Range. One week you're mowing in shorts, the next there's frost on the windshield. In Denver, the gap between a warm September and the first hard freeze can be short, and a home that isn't ready pays for it in higher bills and avoidable repairs. Here's the checklist we'd walk through before winter settles in.
Start outside, before it gets cold
The exterior takes the brunt of Colorado weather, and most of it is easier to handle while temperatures are still mild. Work top to bottom so you're not fixing the same area twice.
- Clean gutters and downspouts — clogged gutters are the number-one cause of ice dams and foundation water.
- Disconnect and drain garden hoses, and shut off exterior spigots to prevent frozen, split pipes.
- Walk the roofline and look for loose, cracked, or missing shingles before snow hides them.
- Reseal gaps around windows, doors, and where pipes enter the house — cheap caulk saves expensive heat.
- Trim branches that overhang the roof; heavy Colorado snow turns them into a hazard.
Protect the systems that keep you warm
Denver's dry air and big temperature swings are hard on heating equipment. A little attention now means the furnace works when you actually need it — usually on the coldest night of the year.
- Replace the furnace filter and schedule a heating check before the first cold snap, when technicians are booked solid.
- Test the thermostat and, if it's older, consider a programmable one to trim winter bills.
- Reverse ceiling fans to clockwise to push warm air back down.
- Check that vents and registers aren't blocked by furniture or rugs.
The small fixes that prevent big bills
Most winter emergencies start as something minor in October. A worn door sweep becomes a cold draft and a higher bill. A slow drip under the sink becomes a burst line once it freezes. Catching these while they're small is the entire point of a fall walk-through — it's cheaper to fix a $20 problem than a flooded basement.
If you'd rather not climb a ladder or crawl under the sink, this is exactly the kind of proactive, top-to-bottom check our seasonal maintenance service is built for. Either way, get it done before the first freeze — your future self will thank you.
