Garage Door Balance Adjustment
On cold mornings the door barely makes it up.
In plain words
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.
How the visit goesThe 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.

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.
Adjusting extension springs at the hook
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.
A record of the setting
Before leaving, the technician tells you how the door was set: the number of turns on each torsion spring or the hook position on each extension spring, the spring dimensions, the door's measured weight if it was weighed, and any parts that were replaced. Writing this on a card by the opener or inside the manual saves a future technician from starting from scratch, and it gives a reference point if the door ever starts to drift. Springs age gradually, so a note that says the door held at a certain number of turns tells a later visit how far things have moved.

What affects the quote
Weight added to the door
Insulation kits, windows or replacement sections may have taken the door beyond what its springs can carry. Weighing the door and specifying new springs to suit is quoted separately from a simple adjustment.
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.
Single or double door
A double door commonly carries more spring than a single, but the exact count follows the manufacturer's engineered hardware package for that door's weight rather than width alone: one, two or more torsion springs, or one or two extension springs per side. More springs means more adjustment and testing.
What to have ready
- Does the door sit level when closed, or is one corner higher?
- Is there a spring on a shaft above the door, or springs along the tracks?
- Is it a single or a double door, and roughly how tall?
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.
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.
Why does the door feel heavier in winter?
Cold stiffens the lubricant in the bearings and hinges and firms up the rubber seals, so the door drags a little more and the springs have slightly more to overcome. A bottom seal frozen to the slab adds to it, and this usually eases as temperatures rise. A door that stays heavy is worth a prompt check regardless of season, since persistent drag can come from binding, an obstructed track, rollers, hinges or cables as well as the spring balance.
