Older detached garages often have extension springs stretched along each horizontal track rather than a shaft above the door. Balancing these works differently: the tension comes from how far each spring is stretched when the door is closed, and it is set by moving the cable attachment along the track hanger or changing the hook position. Both sides are adjusted equally so the door stays level, and the containment cable running through each spring is checked at the same time. The door is opened and clamped so the springs are relaxed during the work, then tested by hand across its travel until it rests where it is left.

Scene 1
Your own observations complete the picture, because you have watched this door every day and the technician has watched it for ten minutes. When did the heaviness start, gradually or all at once? Is it worse on frosty mornings and easier by afternoon? Has anyone worked on the springs, changed the opener or added panels? Does it reverse at a particular point, and did that begin after the last power cut or a bump from the car? Each answer narrows the cause, and together they decide whether the day's work is a straightforward tension adjustment, a cable reset, some friction to remove, or a conversation about springs that have done their years.
Scene 2
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.
Scene 3
Once a month, with the door closed and the light on, look up at the drums and down at the bottom brackets. Each cable should wrap its drum in a single neat layer with the same number of turns on both sides, and hang taut without fraying or rust at the bottom loop. The gap under the door should be even from corner to corner. On an extension door, glance at the two springs for equal length and confirm the containment cable still runs through each. These take less than a minute and tell you the door is still level and the counterbalance still shares the load evenly.
What shapes the quoteMount Nemo Door Specialists
FeesSame any hour
Too much spring tension. The springs are pulling harder than the door weighs, so at rest they win and the door climbs. This often follows a spring replacement wound a turn too far, or a door that lost weight when heavy panels were swapped for lighter ones. Releasing a quarter turn or two, tested after each, brings it back to holding still.
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.
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.
