What does a garage door tune-up actually include?

The checklist, in the order a tech works it

A tune-up is not a guy with a spray can. Here is the sequence our technicians follow on maintenance visits from Norman to Guthrie, roughly bottom to top:

• Visual sweep: panel condition, rust at the bottom section, daylight around the seals, and the bottom weather seal, which Oklahoma sun and slab heat crack within 5 to 7 years.
• Hardware pass: every hinge bolt, track bracket lag, strut bolt, and the opener's header bracket gets checked with a wrench. Doors shake fasteners loose; a thousand-plus cycles a year guarantees it.
• Rollers and hinges: spin each roller looking for wobble, flat spots, or seized bearings; inspect hinges for cracks at the knuckles.
• Cables and drums: look for frayed strands at the bottom brackets and proper seating in the drum grooves. This is the check that prevents the crooked-door emergency.
• Spring inspection: gap check (a gap means broken), rust pitting, and stretch. On torsion systems the tech also verifies the spring is actually the right size for the door, which is not a given after previous cut-rate repairs.
• Balance test: opener disconnected, door lifted to waist height. It should float. This single test predicts most future opener failures; our answer on unbalanced doors explains why.
• Track alignment: plumb on the verticals, level on the horizontals, correct spacing so rollers neither bind nor rattle.
• Lubrication: silicone or lithium spray on springs, hinge pivots, roller bearings, and end bearing plates. Tracks stay dry.
• Opener calibration: travel limits, force settings, chain or belt tension, and gear condition.
• Safety tests: the 2x4 contact reversal test and the photo-eye beam test, both required behavior under UL 325.

What a tune-up is not

Worth being clear, because "tune-up" gets used loosely in ads around the metro. A tune-up does not include replacement parts; if the tech finds a broken spring, worn rollers, or a stripped opener gear, that is a quoted repair on top. It also is not a fix for a door already failing. If your door is off track, slamming, or will not open, you need a repair call, not maintenance. And be wary of bargain-bait tune-up coupons that exist mainly to get a salesperson into your garage. We quote everything up front and estimates are free.

Why it pays for itself here specifically

Oklahoma is hard on doors: 100-degree Julys, ice storms, 60 mph gust fronts, and red dust year-round. The parts that die from that abuse, springs, cables, rollers, weather seal, all show visible warning signs 6 to 12 months before failure, which is exactly the window an annual visit catches. One prevented spring emergency or opener gear replacement pays for several years of tune-ups. If your door is due, or you cannot remember its last service, that is the answer right there.
