Garage Door Balance Adjustment
Since the new insulated panels went in, the door feels like a different animal.
In plain words
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.
How the visit goesOn cold mornings the door barely makes it up. The motor whines, the door crawls, and once or twice it has given up halfway. By afternoon, with the sun on the garage, it runs almost normally again.

How the visit goes
Releasing the door and reading how it behaves
The assessment begins with the opener out of the picture. The technician closes the door, pulls the red manual release so the trolley disconnects, and lifts the door by hand to about a metre, then to full height, then lets it settle. A balanced door pauses wherever it is stopped; a door that climbs on its own has too much tension, one that drops has too little, and one that is fine low down but drifts up near the top can point to drum profile, cable length, uneven section weight or the spring's own characteristics rather than one single cause. How much effort the lift takes and whether it stays fully open are noted before anything is adjusted.
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.
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
Torsion or extension springs
Winding a torsion spring with bars and moving an extension spring's hook are different procedures with different setup, and the type of counterbalance on your door is the first thing that shapes the quote.
Door out of level
A door with one corner high needs its cables reset on the drums before the tension is set, which adds a step to the visit and is listed as its own item.
Adjustment or replacement
If the inspection shows springs that can be wound to the door's weight, the quote covers adjustment. Springs that are undersized or worn out mean replacement, which is priced as separate work and explained first.
What to have ready
- Did the heaviness come on gradually or all at once?
- Does the door behave differently in cold weather?
- Has anything been added to the door, such as insulation, windows or a new section?
Garage Door Balance Adjustment: questions
QuestionsHow long does a balance adjustment take?
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.
How many turns does a torsion spring need?
As a starting point, roughly one full turn for every foot of door height, so a seven-foot door carries a little over seven turns and an eight-foot door a little over eight. The exact figure depends on the drum size and the spring's rating, so the technician winds to the estimate and then fine-tunes by quarter turns until the hand test passes at every height.
How long do garage door springs last?
Springs are rated in cycles, one cycle being an open and a close. A standard residential spring is commonly rated for around ten thousand cycles, which for a family using the door several times a day works out to roughly seven to ten years. Higher-cycle springs are available. As a spring nears its rating it loses tension, which is often why a balance adjustment is needed.
