- The call
- 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.

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.
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.

Garage Door Balance Adjustment · Hamilton

Scene 1
Springs are sized to a door's weight, so the technician asks what has changed since the door was installed. Insulated panels fitted over the original skins, a section replaced after a bump, a row of windows, a heavier bottom seal or decorative hardware all add weight, and even a fresh coat of paint on a wood door counts. Where the history is uncertain, the door can be weighed with the springs relaxed, using a scale under the bottom section. That figure tells the technician whether the existing springs can be adjusted to carry the door or whether the door has outgrown them and needs a different spring specification.
Scene 2
On an extension system the door is opened fully and clamped so each spring hangs slack, and the tension is changed by moving the S-hook or the cable clip to a different hole in the track hanger, or by shortening the cable at the clip. A hole further back stretches the spring more when the door closes and adds lift; a hole further forward reduces it. Both sides are moved the same amount so the door stays level, and the pulleys and containment cables are checked as the hooks are reset. The clamps come off and the door is tested by hand at several heights, then adjusted again if needed.
Scene 3
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.

During a power cut the door is often released and moved by hand for the first time in years, and what people discover is a door that had already grown heavy while the opener quietly covered for it. The outage did not change the springs; it revealed them. A balance check confirms what the door weighs against what the springs give, and resets them to match.
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.
Each corner hangs on its own cable, and if one cable has slipped on its drum, stretched or been wound with a different number of wraps, that corner sits at a different height. On extension doors, one spring stretched more than its partner does the same. The cables or hooks are reset so the door is level, then the tension is set. A level door also stops binding in its track.
