On a torsion door the springs sit on a shaft above the opening, and balance is set by how many turns of wind they carry. A seven-foot door typically needs a little over seven full turns; a quarter turn either way changes how the door feels. The technician clamps the door, fits winding bars into the cone, loosens the set screws, and adds or releases tension one quarter turn at a time, locking the cone again before each test. Both springs on a two-spring door are set alike so the shaft carries the load evenly. That precision is what makes the door hold wherever it is stopped.

Scene 1
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.
Scene 2
With one winding bar seated firmly in the winding cone and a second ready, the technician loosens the cone's set screws and either adds tension by levering the bar upward or releases it by letting the bar down, always a quarter turn at a time, always with a bar in the cone. After each quarter turn the set screws are tightened onto the shaft, the clamp is removed and the door is lifted by hand to test. A door that sank now holds a little higher; a door that climbed now settles. On a two-spring door the same change is made to both springs so they share the load equally.
Scene 3
A balanced door stays balanced longer when the parts that move on every cycle are kept easy. Twice a year, spray a lubricant made for garage doors along the torsion spring, onto each hinge pin, the roller stems and bearings, and the bottom bracket pins, then run the door a few times. Wipe the tracks clean but leave them dry, since a coated track collects grit and lets rollers slide. Avoid heavy grease. Friction is part of what the hand test measures, so a door that is well lubricated reads true, and the springs are not asked to overcome drag that a moment's maintenance would remove.
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.
