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
What you receive from a tune-up is a door that runs better and a written picture of its condition. The technician records what was tightened, lubricated and adjusted, how the balance and reversal tests came out, and which parts are still healthy, which are worth watching and which have reached the point of a separate repair quote. That record turns the next visit into a comparison instead of a fresh start, and it lets you describe a new sound precisely when it appears. Maintenance and repair stay two different decisions, and you make the second one with the facts in front of you.
How the visit goesYou pulled the red cord to lift the door by hand during a power cut and it felt like lifting a car. The opener has been doing all the work and grumbling about it, and you are not sure how long that can go on.

How the visit goes
Watching one full cycle first
Before a wrench comes out, the technician stands clear of the opening and runs the door all the way up and all the way down. They are listening and watching at the same time: where the squeal starts, whether the sections shake at a particular height, whether the door hesitates at the curve of the track, how it lands on the floor, and whether the opener labours or hums. Each observation is tied to a spot on the door or a point in the travel. That map guides the hands-on inspection that follows and gives a fair comparison at the end, when the same cycle is run again after the work.
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.
When to book the next one
How soon the door wants another visit depends on how hard it works. A door that cycles a few times a day, in an attached garage that sees salt, snow and meltwater every winter, does well with a tune-up once a year, usually in the fall before the cold arrives. A lightly used door in a detached garage can often go longer, with the monthly reversal tests and a little lubricant from you in between. The written record is your guide: if it lists parts to watch, the next visit checks those first; if everything was healthy, the interval can stretch. The technician will suggest a timing that fits your door rather than a blanket schedule.

What affects the quote
Season and weather
A winter visit can include freeing a seal frozen to the slab and working with thickened lubricant before the tune-up proper can begin, which adds time to the visit.
Number of doors
Two or three doors on the same property are usually serviced in one visit, and the second and third door are quoted at a different rate from the first because the travel is shared.
Photo-eye and wiring work
Cleaning and realigning sensors is routine. A bent bracket, a chafed wire or a sensor that has failed means a part or a rewire, which is named separately.
What to have ready
- When was the door last serviced, and do you have any paperwork?
- Are the remotes, wall button and keypad all working as expected?
- Can you lift the door by hand with the opener disconnected, and does it stay up?
Garage Door Tune-Up: questions
QuestionsThe sensor light is blinking. What does that mean?
On most openers a steady light on each photo-eye means the pair are aligned and seeing each other, and a blinking light means the beam is interrupted or the sensors are out of line. Common causes are a bracket nudged by a bin or a tire, dust or salt film on a lens, low sun at a certain hour, or a chafed wire. During a tune-up the lenses are cleaned, the brackets straightened, the pair realigned and the wiring checked back to the opener.
What kind of doors and openers do you service?
Residential sectional doors of every common construction: steel, insulated steel, aluminum and glass, wood and composite, single and double width, with torsion springs above the header or extension springs beside the horizontal tracks. Openers of all the usual types are covered too, including chain drive, belt drive, screw drive and wall-mounted jackshaft units. If the door is a one-piece tilt-up or a commercial rolling door, mention that when booking so the right hardware comes along.
How do I test the safety reversal at home?
Two tests, once a month. With the door open, press close and wave a broom handle through the photo-eye beam near the floor: the door should stop and go back up. Next, set a 2x4 flat on the concrete in the middle of the opening and press close: the door must reverse when it meets the board. If it stops on the board without reversing, the down travel or force setting needs adjustment, and if it fails after that, book a visit.
