Someone replaced the springs a while back and the door has bounced at the top ever since. It slams open against the stops, then creeps down a few inches, and the opener trolley rattles because the door is pushing where it should be resting.
The whole service is built around one simple test that door manufacturers and safety bodies describe the same way. With the opener released, the door is lifted by hand to roughly a metre off the floor and let go. A balanced door stays where it is. One that drifts upward is carrying too much spring tension; one that sinks is carrying too little. The technician reads that behaviour at several heights, checks the door is level across its width, and then adjusts the counterbalance a quarter turn at a time, testing to the manufacturer's specified height and tolerance, until the door meets that standard and moves smoothly.

Scene 1
The opener is inspected as a witness rather than a cure. The technician checks its force and travel settings, listens for strain during a powered cycle, and notes whether it reverses near the floor or stalls part way up. A force setting that has been turned up over the years is a strong hint that someone has been compensating for a door that grew heavy. Those settings are left alone for now, because the right order is to balance the door first and then fit the opener to it. Any change made to the opener before the door is corrected would only mask what the door is asking for.
Scene 2
The visit is finished only when the standard tests pass. The technician places a piece of two-by-four flat on the floor in the door's path and closes it with the wall button; the door must strike the wood and return to fully open. Then, with the door closing again, an object is passed through the photo-eye beam, and the door must reverse. Finally the door is released once more and the hand test repeated so you can see it hold at knee height, at waist height and fully open. These are the same checks the door industry's own maintenance checklist uses, and you are welcome to watch each one.
Scene 3
A balanced door lets the opener's safety settings stay at sensible values, and it is worth keeping them there. If the door ever starts to reverse for no reason or struggles to lift, resist the temptation to turn the force up on the motor; that hides a door that has grown heavy again and takes the entrapment protection out of its proper range. Instead, release the door and try the hand test. If it no longer holds, the springs want attention, and a balance adjustment puts the weight back on them so the opener can remain at the gentle settings it was left with.
What shapes the quoteConcord Garage Door Services
FeesSame any hour
Too much spring tension. The springs are pulling harder than the door weighs, so at rest they win and the door climbs. This often follows a spring replacement wound a turn too far, or a door that lost weight when heavy panels were swapped for lighter ones. Releasing a quarter turn or two, tested after each, brings it back to holding still.
It means the springs carry nearly all of the door's weight, so the door itself feels close to weightless. Balanced, it will stay put at any partly open position when moved by hand, stay fully open on its own, and close without slamming. The opener then only has to guide the door rather than lift it, which is how it was designed to work.
There is no fixed interval; the door tells you. Many doors go years between adjustments, especially when they are lubricated and the springs were sized correctly. A hand test each season is the reliable guide: if the released door holds at about a metre and stays fully open, it is fine. When it starts to drift or sink, that is the time.
