Garage Door Tune-Up
The door lands with a thud you can feel through the kitchen floor, and sometimes it bounces back up a few centimetres before settling.
In plain words
The heart of a tune-up is the balance check. Your springs are meant to carry nearly the whole weight of the door so the opener only has to guide it. When the door is disconnected from the opener and lifted by hand, it should rise without effort, stay open on its own and hold still partway. A door that sinks or feels heavy is telling you the springs have lost tension, and an opener made to move a balanced door is straining. The tune-up identifies this and treats spring adjustment as its own carefully done job, with the door clamped and proper winding bars.
How the visit goesTwice this week the door started closing, stopped a metre from the floor and reopened on its own. One of the little sensor lights near the floor blinks instead of glowing steady, and the wall button has to be held to close it.

How the visit goes
Seals, weatherstrip and the threshold
The bottom seal is checked along its whole length for tears, flattening and stiffness, and the threshold is looked at for the low spots where water pools and freezes. The jamb and header weatherstrip are pressed to see whether the rubber or vinyl still flexes or has gone hard, and the technician notes any daylight showing when the door is closed. Because the opener's travel limit decides how firmly the door presses onto its seal, the two are read together: a crushed seal often means the down limit is set too far, and a gap often means the door is stopping early. This part of the check matters most before winter.
Tightening what the door shook loose
A garage door moves hundreds of kilograms of steel through a curve twice a day, and the vibration works on every screw. The technician goes back along the list made during inspection and tightens hinge screws, track bolts, bracket lags and the fasteners at the opener header and rail. Stripped screws are replaced with the next size, and missing ones are filled. Track brackets are snugged with the roller-to-track gap preserved so nothing binds. The bottom brackets and anything anchored to the springs are deliberately left alone, since they hold the door's weight under tension; if one of those is loose it becomes a separate job with the tension safely released first.
Ready for the cold months
After a fall tune-up the door is set up for the season that tests it hardest. The lubricant on the moving parts stays fluid in the cold rather than thickening into a drag on the opener. The bottom seal and jamb weatherstrip have been treated so they stay flexible below freezing and release from the slab instead of tearing. If the seal ever freezes down on a bad morning, free the ice and dry the area before running the door rather than letting the opener force it; that habit protects the top section better than any force setting. You have been shown the threshold spot where water pools, and clearing snow and ice there becomes part of shovelling the driveway.

What affects the quote
Balance findings
If the balance test shows the springs have lost tension, spring adjustment or replacement is a separate job with its own quote rather than part of the maintenance visit.
Time since the last service
A door serviced last year needs a lighter touch than one that has never been looked at, where every fastener may want attention and the sensors and limits are far from where they should be.
Written record and follow-up
A basic handover note is part of every visit. A detailed condition report with photographs for a landlord, a strata or a home sale is available as an added item.
What to have ready
- What have you noticed: noise, shaking, hesitation, slamming, or reversing on its own?
- When was the door last serviced, and do you have any paperwork?
- Are the springs mounted above the door or along the sides beside the tracks?
Garage Door Tune-Up: questions
QuestionsWhat does a garage door tune-up actually include?
A full cycle observed before any work, a hands-on inspection of hinges, rollers, tracks, springs, cables, drums, brackets and the opener's attachments, tightening of the accessible fasteners, lubrication of the moving points with a garage door lubricant, a balance check with the door disconnected from the opener, adjustment of the opener's travel and force, cleaning and alignment of the photo-eyes, both reversal tests, a look at the seals, and a written record of the findings.
Should I lubricate the tracks?
No. Tracks should be clean and dry. Rollers are meant to roll along the track on their own bearings, and a film of lubricant on the track collects grit, thickens in the cold and makes the rollers slide and drag instead. Wipe the tracks with a rag and put the lubricant where it belongs: on the hinge pins, the roller bearings, the spring coils and the bearing plates at the ends of the torsion shaft.
Do you adjust the springs during a tune-up?
Springs are inspected and lubricated during a tune-up, and the balance test tells us whether they are carrying the door's weight properly. Changing their tension is a separate, deliberate job: the door is clamped to the track, winding bars are used on a torsion spring, and the technician works from a stable position. If the balance check shows the springs need adjustment or replacement, you receive that as its own recommendation with its own quote.
