- The call
- Since the new insulated panels went in, the door feels like a different animal. It closes with a thud, the opener labours where it used to hum, and lifting it by hand takes a proper heave rather than a fingertip.

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.
A garage door is balanced when its springs carry almost the whole weight of the door, so the door itself is nearly weightless in your hands and the opener only has to guide it. Balance adjustment is the service that restores that state. The technician disconnects the opener, moves the door by hand to see where it drifts or sinks, inspects the springs, cables and rollers, and then changes the spring tension in measured steps until the door holds still partly open, stays up when fully raised, and closes without slamming. The opener is then reconnected and its settings checked against the corrected door.

Scene 1
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.
Scene 2
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.
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.
What shapes the quoteMount Joy Door & Opener Co.
FeesSame any hour
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.
The opener is built to move a balanced door, and its force limit is what makes it stop and reverse on contact. Raising that limit to lift a heavy door pushes the safety behaviour out of its intended range and works the motor and gears hard. The sound order is to balance the door first, then set the opener to suit it. Both are done in the same visit.
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.
