Garage Door Balance Adjustment
The 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.
Garage Door Balance Adjustment
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 goesThe opener has started to groan on the way up. The door climbs slowly, hesitates near the top, and on the way down it sometimes stops a hand's width above the floor and reverses, as if something were in the way when nothing is.

How the visit goes
Inspecting the springs before any turns are added
Adjustment only makes sense on a spring that is sound, so each one is examined closely. On a torsion system the technician looks for a gap in the coil, rust pitting, uneven coil spacing and a cone that has slipped on the shaft, and measures the wire size, inside diameter and length to confirm the spring suits the door's weight. On extension springs the check is for stretched or opened coils, a broken end loop and the presence of a containment cable. A spring that has simply lost a little tension can be wound up; one that is undersized or near the end of its cycle life is explained and offered as a replacement instead.
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.
The seasonal hand test you can do yourself
You can repeat the balance test any time without touching a spring. With the door closed, pull the manual release cord so the trolley disconnects, lift the door by a handle or a safe gripping point to about a metre, and let go gently. A balanced door stays roughly where you leave it; one that creeps up or sinks has drifted and is worth a call before it becomes heavy work for the opener. Reconnect the opener as its manual describes, usually by running it once. Doing this at the start of each season, when the temperature changes, is the simplest way to catch a change early.

What affects the quote
Same fees day, night or weekend
1Door 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.
2Single or double door
A double door commonly carries more spring than a single, but the exact count follows the manufacturer's engineered hardware package for that door's weight rather than width alone: one, two or more torsion springs, or one or two extension springs per side. More springs means more adjustment and testing.
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
Can a door with a broken spring be balanced?
A broken spring is replaced rather than adjusted; there is nothing left to wind. On a two-spring door the technician normally replaces both, since the survivor has the same age and cycle count, and then balances the door on the new pair. Until the visit, leave the door closed and avoid running the opener, which is not designed to lift the door's full weight on its own.
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.
What does it mean for a garage door to be balanced?
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.
