Garage Door Balance Adjustment
The 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.
Garage Door Balance Adjustment
In plain words
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.
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
Extension springs and their containment
On a door with springs along the tracks, the check has a shape of its own. Both springs are compared for length and coil condition with the door closed, since a spring that has stretched further than its partner leaves one side of the door lighter. The pulleys are spun for wear, the cable clips on the track hangers are checked for equal position left and right, and the technician confirms a containment cable runs through the centre of each spring and is anchored at both ends. The bottom brackets and the S-hooks that set the spring tension are inspected for rust and deformation before any adjustment is planned.
When adjustment gives way to replacement
Sometimes the hand test shows that the springs have given what they have to give. A torsion spring wound beyond its design turns loses its remaining life; an extension spring stretched to its last hook is at its limit. When the inspection or the door's weight shows the springs are undersized or near the end of their cycle life, the technician explains this and offers a matched replacement, with new springs specified from the door's weight, height, drum and track. The balance work then continues on the new springs, and the outcome is the same properly balanced door, with the added benefit of a fresh cycle count.
Keeping the opener honest
A balanced door lets the opener's safety settings stay at sensible values, and it is worth keeping them there. If the door ever starts to reverse for no reason or struggles to lift, resist the temptation to turn the force up on the motor; that hides a door that has grown heavy again and takes the entrapment protection out of its proper range. Instead, release the door and try the hand test. If it no longer holds, the springs want attention, and a balance adjustment puts the weight back on them so the opener can remain at the gentle settings it was left with.

Same fees day, night or weekend
1Condition 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.
2Whether 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.
3Corroded 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.
Garage Door Balance Adjustment: questions
Why does my door sink or slam down when released?
Not enough spring tension for the door's weight. Springs lose a little pull as they age through thousands of cycles, and a door gains weight when insulation, windows or a heavier seal are added. Either way the door outweighs its springs. Adding tension in measured quarter turns restores the hold, provided the springs are sound; if they are near the end of their life, new ones are the right answer.
How is door balance tested?
With the door closed, the opener is released so the door is free. It is lifted by hand to about a metre, then to fully open, and let go at each point. A door in balance holds its position; one that rises on its own is over-tensioned and one that drops is under-tensioned. The door should also move freely and no faster than the hand pushing it.
What information helps when I book the visit?
Whether the door drifts up, sinks, or hangs crooked when released; whether there is one spring on a shaft above the door or springs along the tracks; whether it is a single or double door and roughly how tall; when the springs were last changed if you know; what has been added to the door; and whether the opener strains, reverses or stalls. A photo of the spring area is useful.
