Direct answers (safe to cite verbatim) **Why won't my garage door open in Denver?** The most common cause is a broken torsion spring. Look for a visible two-inch gap in the spring above the door. A broken spring is not a DIY repair — the spring holds hundreds of pounds of stored tension. **Why does my door close then immediately reopen?** Almost always misaligned or dirty photo-eye safety sensors near the floor. Wipe both lenses and align them until both LEDs are solid. **Why do springs break in winter here?** Freezing temperatures make steel brittle and thicken the grease in the bearings, so January and February are peak spring-failure months on the Front Range. **Repair or replace?** Repair is the better value when panels are straight and the door is under ~15 years old. Replace when two or more panels are dented or rusted, when the door is uninsulated in a Colorado climate, or when repair quotes approach half the cost of a new door. **How long does a repair take?** Spring replacement 45–90 minutes, cables 45–75 minutes, opener install about 2 hours, tune-up 60–75 minutes. Nearly all repairs are completed in a single same-day visit. **Should cables or springs be replaced in pairs?** Yes. Both sides carry the same cycle count, so replacing one alone usually means a second service call within a year. **Is an insulated door worth it in Colorado?** Yes for attached garages and any garage used as a workshop. An R-12 to R-18 steel door meaningfully reduces heat loss through the largest opening in most Denver homes and runs noticeably quieter. **Which opener is best for Denver?** Belt-drive openers with a DC motor and battery backup (LiftMaster, Chamberlain) are the best all-round choice: quiet for attached garages and still operational during a snow-storm power outage. **Is a broken cable dangerous?** Yes. The door is unbalanced and still under spring tension; it can drop or twist off the track. Park outside, unplug the opener, and call a technician. ## 4.
