A garage door is the heaviest moving object in your house and the one nobody maintains. An hour in autumn prevents most of the failures on the rest of this site.
Most garage door failures in this region happen in the first sustained cold of the season, and most of them were detectable in September or October. A spring at the end of its cycle life, a roller with a seized bearing, a hardened bottom seal, a cable corroding at its bracket from last winter's de-icer, a wide door with no strut heading into windstorm season. All visible, all cheap to address before they become a 6 a.m. emergency in January with the car trapped inside.
It starts with the one test that matters most: opener disconnected, door raised by hand to waist height, and released. A correctly counterbalanced door stays put. One that sinks or climbs is telling us its springs are wrong, and no amount of work on the opener will fix that.
From there:
Most homeowners who lubricate a door use whatever spray is on the shelf, and the common ones are wrong for this climate. Light household oils thicken as temperature drops, so a door that was quiet in September is loud and sluggish in December and the opener works considerably harder than it should, which is how a perfectly good opener starts hitting its force limit and reversing. A lithium or silicone-based garage door lubricant stays workable in the cold. And never grease the track: rollers are meant to roll along it, and lubricant there collects grit and makes them skid.
A tune-up is not a warranty and we will not pretend it prevents everything. It certainly does not prevent hail. What it reliably does is convert emergencies into scheduled work. Finding a spring at 9,500 cycles in October means replacing it on a Tuesday afternoon at standard rates rather than at 6 a.m. in January at after-hours rates with a car trapped behind it. Fitting a strut in October costs a fraction of replacing a creased top section in March.
Once a year for a door in daily use, and autumn is the best timing here so problems surface before the first hard freeze and before windstorm season. Twice a year if the door is your main entrance.
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.
A lithium or silicone-based garage door lubricant, which stays workable in the cold. Avoid thin household oils that thicken when it is freezing, and never lubricate the track itself.
No, and we will not claim it does. What it does is catch the mechanical failures that are preventable, and identify whether a wide door needs a strut before windstorm season.
