Garage Door Balance Adjustment
You pulled the red cord to move the door by hand during the power cut, lifted it to about waist height and let go.
In plain words
A balance visit follows a settled order. The technician first checks for a broken spring, displaced cable, binding or track damage; once safe to move, the door is run through a powered cycle, then released to repeat the movement by hand, separating the motor from the door. Springs, cables, drums, rollers, hinges and track are inspected before anything changes. Adjustment comes next, in small steps with a test after each one, until the door holds at every height and sits level. Finally the opener is reconnected, its settings reviewed against the newly balanced door, and the reversing safety tests run while you watch.
How the visit goesReleased from the opener, the door will not hold anywhere. Lift it to hip height, take your hands away, and it sinks back to the concrete, gathering speed on the way down. Two years ago it used to hover exactly where you left it.

How the visit goes
Talking through what you have noticed
Your own observations complete the picture, because you have watched this door every day and the technician has watched it for ten minutes. When did the heaviness start, gradually or all at once? Is it worse on frosty mornings and easier by afternoon? Has anyone worked on the springs, changed the opener or added panels? Does it reverse at a particular point, and did that begin after the last power cut or a bump from the car? Each answer narrows the cause, and together they decide whether the day's work is a straightforward tension adjustment, a cable reset, some friction to remove, or a conversation about springs that have done their years.
Adding or releasing quarter turns on a torsion spring
With one winding bar seated firmly in the winding cone and a second ready, the technician loosens the cone's set screws and either adds tension by levering the bar upward or releases it by letting the bar down, always a quarter turn at a time, always with a bar in the cone. After each quarter turn the set screws are tightened onto the shaft, the clamp is removed and the door is lifted by hand to test. A door that sank now holds a little higher; a door that climbed now settles. On a two-spring door the same change is made to both springs so they share the load equally.
A door that is nearly weightless again
The difference is obvious the first time you lift the door by hand. It rises with light effort, pauses when you stop it, and stays fully open without drifting down. Closing it, the bottom seal meets the slab evenly along its length instead of thudding at one corner. Under power, the opener runs quieter because it is guiding a balanced door rather than hauling one, and it stops reversing near the floor for no reason. The door also moves at the speed of your hand, neither racing ahead nor dragging, which is exactly what the industry checklist describes as correct operation.

What affects the quote
Commercial or oversized doors
Doors wider or heavier than a standard residential opening use heavier springs, sometimes several on one shaft, and take longer to wind and test, which the quote reflects.
Rollers, hinges and friction repairs
Seized rollers or worn hinges that made the door heavy are pointed out and offered as optional items, since replacing them while the technician is at the door is efficient.
Door height and lift type
Taller doors and high-lift or vertical-lift hardware carry more spring turns and different drums, so setting and testing them takes longer than a standard seven-foot door.
What to have ready
- Does the door behave differently in cold weather?
- Has anything been added to the door, such as insulation, windows or a new section?
- Does the door sit level when closed, or is one corner higher?
Garage Door Balance Adjustment: questions
QuestionsMy door has become noisy. Is that related to balance?
Often, yes. A door that has grown heavy makes the opener labour, the chain or belt slap, and the rollers and hinges complain under load they were never meant to carry. Balancing the door takes that load back onto the springs, and the lubrication and roller checks that come with the visit quiet the rest. A door that runs silently is usually a door that runs light.
How should I prepare the garage for the visit?
Move the car out if you can and clear the floor near the door and beneath the spring shaft, since the technician will be on a ladder there with winding bars. Take down anything hanging from the tracks or stored on top of the horizontal rails. Leave the door where it is, make sure the wall button and the opener are reachable, and have any spring or opener paperwork handy.
What safety tests are done after the adjustment?
Two are standard. A piece of two-by-four is laid flat on the floor in the door's path and the door closed onto it; it must reverse and return to open. Then, as the door closes, an object is passed through the photo-eye beam near the floor, and again the door must reverse. Both depend on a balanced door, which is why they come after the adjustment rather than before.
