Why Cortez Winters Are Hard on Garage Doors (And What to Do About It)
2026-03-19 7 min read
If you've lived in Cortez long enough, you know our winters don't mess around. We're sitting at over 6,200 feet in the Four Corners region, and while we enjoy around 240 sunny days a year, January can dump over 8 inches of snow in a single month with average lows dipping to the mid-20s°F. That cycle of daytime warming and overnight freezing is exactly what makes garage door maintenance so critical for homeowners here. and it's something that catches a lot of people off guard.
Whether you're in an older ranch-style home along the Montezuma Avenue Historic District, a newer build in Fairway Estates, or out on a rural property near Dolores, your garage door takes a beating every winter. Here's what actually happens to your system in the cold, and what you can do to stay ahead of it.
How Cold Weather Damages Your Garage Door System
The short answer: a lot of ways, and often all at once.
Frozen Lubrication
One of the most common winter failures starts with your lubricant. When temperatures drop, grease and oil-based lubricants thicken and become sticky. That thick, gummy residue makes it much harder for rollers, hinges, and tracks to move. often creating a loud groaning sound when the door operates. The fix is straightforward: clean off the old hardened lubricant with a grease solvent, then reapply a silicone-based lubricant to all metal moving parts. Whatever you do, avoid WD-40 on your garage door. it can actually make cold-weather sticking worse.
Springs Become Brittle
Cold metal contracts, and torsion springs are already under tremendous tension on a warm day. When temperatures plunge overnight, the metal in your springs becomes more brittle and susceptible to snapping. A broken spring often announces itself with a loud bang. sometimes described as sounding like a gunshot. followed by a door that won't budge. If you notice your door feeling heavier than usual or moving unevenly, that's your warning sign before the snap happens. Check our frequently asked questions for more on what broken spring symptoms look like.
The Door Freezes to the Ground
This one is especially common here in Cortez, where we see that classic freeze-thaw cycle. Snow or rain collects at the base of the door, and when overnight temps drop. sometimes to 15°F or below. the bottom weatherseal freezes directly to the concrete. Never force the door open with the opener when this happens. You'll likely rip the weatherseal, which then lets cold air, moisture, and pests into your garage all winter long. Instead, use warm water to gently melt the ice, dry the area, and apply a silicone spray to the bottom seal to help prevent it from refreezing.
Sensor Problems
Colorado's intense sunshine is actually its own problem for garage doors. and Cortez gets plenty of it. Photo-eye safety sensors near the base of your door can be blinded by direct sunlight, causing the door to reverse unexpectedly. In winter, frost and condensation on those same sensors can block the beam entirely and prevent the door from closing. Wipe your sensors regularly with a dry cloth, and if you're experiencing phantom reversals, check whether sun angle is the culprit before assuming something's broken.
What You Can Do Right Now
You don't need to wait for something to break. A little preparation goes a long way when Cortez winter sets in.
Pre-Winter Checklist
- Lubricate all moving parts with a silicone or lithium-based lubricant. rollers, hinges, springs, and tracks - Inspect your weatherstripping along the bottom and sides of the door; if it's cracked, stiff, or pulling away, replace it before the hard freezes arrive - Check your remote batteries. cold temperatures drain batteries faster than you'd expect, and a dead remote on a freezing morning is a frustrating problem with an easy fix - Test your door balance by disconnecting the opener and lifting the door manually to waist height; a properly balanced door stays in place on its own - Clear snow and water from the base of your door at night when temps are expected to drop below freezing
Insulating your garage is also worth considering if you use it as a workshop or main entry point into the home. An insulated garage door holds heat better and reduces the stress that dramatic temperature swings put on every component of the system.

When to Call a Pro
Some of these tasks are genuinely DIY-friendly. Lubricating your door, swapping out remote batteries, cleaning sensors. all of that is well within reach for most homeowners. But certain repairs are not safe to tackle yourself. Torsion spring replacement is at the top of that list. Springs store enough mechanical energy to lift hundreds of pounds, and when released incorrectly they can cause serious injury. If your spring looks rusted, has a visible gap in the coil, or your door has suddenly become very heavy to lift manually, stop using the door and call a professional.

Frequently Asked Questions
Q: Why does my garage door open fine in the afternoon but stick in the morning? A: This is a classic Cortez freeze-thaw problem. Daytime temps warm the concrete and door components, but overnight the moisture that collects under the weatherseal freezes solid. The door is stuck to the ground, not broken. Use warm water to free it and apply silicone spray to the bottom seal each evening when temps are expected to drop below freezing.
Q: Can I use WD-40 to lubricate my garage door in winter? A: It's best to avoid it. WD-40 is a water displacer, not a true lubricant, and it can actually cause lubricant to harden in cold temperatures and create more friction. Use a dedicated silicone-based or lithium-grease garage door lubricant instead.
Q: How do I know if my opener is struggling because of the cold or because of a failing spring? A: Disconnect your opener and try to lift the door manually. If it's very heavy or won't stay up on its own when lifted halfway, your springs are likely the issue. If the door moves freely by hand, the problem is with the opener itself. possibly thickened lubricant, a battery issue, or sensitivity settings that need adjustment for cold weather.
