Garage Door Balance Adjustment
The opener has started to groan on the way up.
In plain words
What you get back is a door that lifts with light, even effort and a written note of how it was set. It holds still at knee height, at waist height and fully open, closes onto the floor gently along its whole length, and rises without twisting. The opener sounds relaxed because it is steering rather than lifting, and it reverses cleanly when the safety tests are run. The technician tells you how many turns the springs carry, whether any parts are nearing the end of their life, and how to repeat the hand test yourself each season so you notice any drift early.
How the visit goesYou 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.

How the visit goes
Friction along the path
Some doors that feel heavy are not short of spring tension at all; they are dragging. The technician runs a hand and an eye along the vertical and horizontal tracks for dents, misaligned joints and brackets that have pulled away from the jamb, spins each roller to find seized bearings or cracked wheels, and flexes each hinge for play or splits. Dry, worn rollers alone can add real effort to every lift. Binding at one point in the travel, rather than heaviness everywhere, is the signature of a friction problem, and correcting it first means the springs are then adjusted to the door's true weight rather than to the drag.
Resetting the cables so the door sits level
If one corner of the door sat high, that is corrected before the final tension is set. The technician releases the spring tension enough to take the load off the drums, loosens the set screws on the drum on the low side, takes up or lets out cable until the door is level, and locks the drum again with the cable seated snugly in its groove. The bottom of the door is checked against the floor along its whole width, and both drums are confirmed to show the same number of wraps. Only then is the spring tension brought back up, because tension applied to a crooked door simply loads one side more.
Cables and level, checked with a glance
Once a month, with the door closed and the light on, look up at the drums and down at the bottom brackets. Each cable should wrap its drum in a single neat layer with the same number of turns on both sides, and hang taut without fraying or rust at the bottom loop. The gap under the door should be even from corner to corner. On an extension door, glance at the two springs for equal length and confirm the containment cable still runs through each. These take less than a minute and tell you the door is still level and the counterbalance still shares the load evenly.

What affects the quote
Condition 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.
Corroded or seized fasteners
Set screws and cone screws that have rusted solid take time to free, and badly corroded hardware is replaced rather than reused, which shows in the parts list.
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.
What to have ready
- Is there a spring on a shaft above the door, or springs along the tracks?
- Does the opener strain, stall, or reverse before reaching the floor?
- Did the heaviness come on gradually or all at once?
Garage Door Balance Adjustment: questions
QuestionsI am getting a new opener. Should the door be balanced first?
Yes, and installers will usually insist on it. A new opener is set up against the door it meets on the day, so its travel and force settings are only right if the door is already balanced. Fitting a new motor to a heavy door shortens the motor's life and puts the safety reversal out of range. Balancing first means the new opener starts life doing the light work it was designed for.
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.
How long does a balance adjustment take?
A straightforward tension adjustment on a sound door is generally about an hour, including the inspection, the hand tests and the opener checks at the end. Resetting cables to level the door, replacing rollers to remove friction, or moving to a spring replacement adds time. The technician will tell you what the inspection found and how the visit is shaping up before the work continues.
