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
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 goesThe door has grown heavy so gradually you stopped noticing, until a visitor tried to lift it and could not. The opener still manages, but it sounds strained, the chain slaps on the way up, and the wall button gets pressed twice most mornings.

How the visit goes
Cables, drums and whether the door sits level
A door that is out of level is usually a cable story rather than a spring story. The technician checks that each cable wraps its drum in a single neat layer with the same number of wraps on both sides, that the drum set screws are tight on the shaft, and that neither cable is frayed or rusting at the bottom bracket. A tape across the bottom of the door in the closed position shows whether one corner sits high. If it does, the cables are reset on the drums so the door is level before spring tension is judged, because a crooked door binds in its track and feels heavy regardless of how the springs are wound.
Fitting the opener to the balanced door
Once the door holds at every height by hand, the opener is reconnected and treated as its own step. Its travel limits are checked so the door closes fully onto the floor and opens to the correct height without straining against the stops. The force settings are reviewed, and where they had been raised to cope with a heavy door they are brought back to a sensible level, because the door no longer needs the help. The photo eyes are cleaned and aligned. The technician then runs several powered cycles and listens for the motor working lightly and evenly through the whole travel.
What the springs still have left
Part of the visit's value is knowing where the springs stand. If they were adjusted and left in place, you will have been told roughly how much life they appear to have and what signs mark their end: a door that grows heavy again within a season, a coil gap, or rust flaking from the wire. If they were replaced, the door starts a new cycle count and the note by the opener says when they went in. Either way, you can plan the next spring work on your own schedule rather than on the morning the car needs to leave and the door refuses to lift.

What affects the quote
Weight added to the door
Insulation kits, windows or replacement sections may have taken the door beyond what its springs can carry. Weighing the door and specifying new springs to suit is quoted separately from a simple adjustment.
Adjustment or replacement
If the inspection shows springs that can be wound to the door's weight, the quote covers adjustment. Springs that are undersized or worn out mean replacement, which is priced as separate work and explained first.
Lubrication and tune-up
Some people combine the balance adjustment with a full lubrication and hardware tightening. That bundle is priced as a whole and saves a separate maintenance visit.
What to have ready
- When were the springs last replaced or adjusted, if you know?
- Do you have the door or opener manual, or a label with the model?
- Is there a spring on a shaft above the door, or springs along the tracks?
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.
What is the red cord hanging from the opener for?
It is the manual release. Pulling it disconnects the door from the opener's trolley so the door can be moved by hand, which is how the balance test is done and how you get the car out during a power cut. The industry standard calls for it to be red and reachable, no more than about six feet above the floor. Reconnecting is usually as simple as running the opener once.
Is this something I can do myself?
The hand test, yes, and it is a good habit. The adjustment itself is a job for a trained technician, because the springs, cables, drums and bottom brackets are under high tension whenever the door is closed, and the industry's own guidance reserves any change to them for someone with the right bars, clamps and method. Leaving that part to the visit keeps the whole thing uneventful.
