Why choose CMC Door Service
It is $99 and it is fixed
Not a call-out charge that turns into a quote. Ninety nine dollars covers the visit and everything listed below. If we find something that needs a part, you get the price and you decide.
The point is catching the spring
A torsion spring gives warning. The door gets heavier, the opener starts labouring, the balance goes off. A tune-up is where that gets noticed, which is the difference between a planned spring change and a door on the floor with the car behind it.
Twice a year on a door used daily
A door that goes up and down four times a day does around 1,500 cycles a year, and most residential springs are built for 10,000. Servicing on that rhythm is what gets you the full life out of them.
What the $99 tune-up actually includes
Balance test
Opener disconnected, door lifted by hand to waist height and released. A correctly sprung door stays where you put it. If it climbs or drops, the spring is wrong for the door and everything else is downstream of that.
Spring inspection and re-tension
Coils checked for gaps and for rust, and tension adjusted until the door balances. On a two spring door both are inspected, because they have aged together and they fail together.
Rollers, hinges and end bearings
Every roller spun by hand for flat spots and seized bearings, every hinge checked for elongated holes, and the end bearing plates checked for play. This is where the noise almost always comes from.
Track alignment
Verticals checked for plumb, horizontals for level and for the correct gap to the door, and every bracket bolt checked for tightness. Vibration walks those loose over a couple of years.
Safety reversal test
Photo eyes aligned and tested, and the down force checked against a solid object so the door reverses the way it has to. This is the test that matters if there are children or pets in the house.
Lubrication, in the right places
Springs, bearings, hinges and the opener rail get the correct lubricant. Not the tracks, which people spray and then wonder why the rollers slide instead of rolling.
The parts a tune-up touches
Motor, rail, arm, release
A tune-up is mostly these four things: the motor head, the rail it drives, the arm that connects it to the top section, and the release cord that has to work when you need it. Filmed on one of our own jobs.

FAQ
Frequently asked questions
How often should a garage door be serviced?
Once a year for a typical household door, and more often for high-cycle or commercial doors. Florida's salt air and humidity are hard on cables, rollers and hardware, so annual servicing matters more here than in a dry climate.
What is included in a garage door tune-up?
A 25-point inspection covering spring tension and balance, rollers, hinges, cables, tracks, opener force and travel limits, photo-eye safety sensors, lubrication of moving parts, and weatherseal condition.
Will a tune-up stop my door being noisy?
Usually. Most noise comes from dry or worn rollers, loose hardware and unlubricated hinges, all of which a tune-up addresses. Worn steel rollers can be upgraded to nylon for a quieter door.
Can a tune-up prevent a spring from breaking?
It cannot make springs last forever, but correct balance and lubrication reduce strain, and an inspection catches gaps in the coils or fraying cables before they fail without warning.
Do you service doors you did not install?
Yes. We service all brands and any age of door, whoever installed it.
