A garage door is the heaviest moving object in your house and the one nobody maintains. An hour a year, ideally before the cold sets in, prevents most of the failures on the rest of this site.
Most garage door failures in the Black Hills area happen in the first sustained cold of the season, and most of them were detectable in the fall. A spring at the end of its cycle life, a roller with a seized bearing, a hardened bottom seal, a cable rusting at its bracket: all visible, all cheap to address before they become a 6 in the morning emergency in January with the car trapped inside.
Most homeowners who lubricate a door use whatever spray is in the garage, and the common ones are wrong for this climate. Light household oils thicken as the temperature drops, so a door that was quiet in September gets loud and sluggish in December and the opener works harder than it should. A lithium or silicone-based garage door lubricant stays workable when it is well below freezing. And never grease the track: the rollers are meant to roll along it, and lubricant there collects grit and makes them skid instead.
A tune-up is not a magic warranty, and nobody honest will pretend it prevents everything. What it reliably does is convert emergencies into scheduled work. Finding a spring at 9,500 cycles in the fall means replacing it on a Tuesday afternoon at standard rates rather than at 6 in the morning in January at after-hours rates with a car trapped behind it. On the area aging builder-grade doors, that difference comes up often.
Once a year for a door in daily use, and autumn is the best timing in the Black Hills area so problems surface before the first hard freeze. Twice a year if the door is your main entrance or the garage is unusually dusty, as acreage and gravel-drive garages tend to be.
Some of it, safely: wiping and aligning the photo-eyes, checking for frayed cable, testing the safety reversal, and lubricating hinges and rollers with proper garage door lubricant. Never adjust or work on torsion springs. The stored energy in them is genuinely dangerous.
A lithium or silicone-based garage door lubricant, which stays workable in the cold. Avoid thin household oils that thicken when it is below freezing, and never lubricate the track itself. Rollers need to roll, not slide.
Often it is the best money on an old door, because it tells you honestly how much life is left and lets you plan a replacement instead of being forced into one on the coldest morning of the year.
