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. Instead of staying put, it kept climbing on its own and thumped into the fully open stop.
Garage Door Balance Adjustment
In plain words
On a torsion door the springs sit on a shaft above the opening, and balance is set by how many turns of wind they carry. A seven-foot door typically needs a little over seven full turns; a quarter turn either way changes how the door feels. The technician clamps the door, fits winding bars into the cone, loosens the set screws, and adds or releases tension one quarter turn at a time, locking the cone again before each test. Both springs on a two-spring door are set alike so the shaft carries the load evenly. That precision is what makes the door hold wherever it is stopped.

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.
Proving the result with the safety tests
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.
Keeping the opener honest
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 affects the quote
Same fees day, night or weekend
1Condition of cables and drums
Cables that are fraying or drums with worn grooves found during the check are recommended for replacement while the system is being set, and quoted as their own items.
2Extension-spring containment and pulleys
On an extension door, a missing containment cable is added and worn pulleys are replaced with the adjustment. Each is a small parts line on the quote.
3Whether a second person is needed to support the door
A heavier double door or one already sitting unevenly is sometimes safer to adjust with a second person steadying it while the springs are reset. That extra pair of hands is called in once the technician sees how the door is behaving on site.
Garage Door Balance Adjustment: questions
How long do garage door springs last?
Springs are rated in cycles, one cycle being an open and a close. A standard residential spring is commonly rated for around ten thousand cycles, which for a family using the door several times a day works out to roughly seven to ten years. Higher-cycle springs are available. As a spring nears its rating it loses tension, which is often why a balance adjustment is needed.
How is door balance tested?
With the door closed, the opener is released so the door is free. It is lifted by hand to about a metre, then to fully open, and let go at each point. A door in balance holds its position; one that rises on its own is over-tensioned and one that drops is under-tensioned. The door should also move freely and no faster than the hand pushing it.
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.
