- The call
- You 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.

The whole service is built around one simple test that door manufacturers and safety bodies describe the same way. With the opener released, the door is lifted by hand to roughly a metre off the floor and let go. A balanced door stays where it is. One that drifts upward is carrying too much spring tension; one that sinks is carrying too little. The technician reads that behaviour at several heights, checks the door is level across its width, and then adjusts the counterbalance a quarter turn at a time, testing to the manufacturer's specified height and tolerance, until the door meets that standard and moves smoothly.

Scene 1
A door that is out of level is usually a cable story rather than a spring story. The technician checks that each cable wraps its drum in a single neat layer with the same number of wraps on both sides, that the drum set screws are tight on the shaft, and that neither cable is frayed or rusting at the bottom bracket. A tape across the bottom of the door in the closed position shows whether one corner sits high. If it does, the cables are reset on the drums so the door is level before spring tension is judged, because a crooked door binds in its track and feels heavy regardless of how the springs are wound.
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
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 shapes the quoteOtonabee Garage Door Services
FeesSame any hour
A torsion door has springs on a shaft above the opening, and tension is changed by winding the springs with steel bars, a quarter turn at a time. An extension door has springs along the tracks, and tension is changed by moving the hook or cable clip to a different position with the door open and clamped. The hand test that proves the result is the same for both.
Two are standard. A piece of two-by-four is laid flat on the floor in the door's path and the door closed onto it; it must reverse and return to open. Then, as the door closes, an object is passed through the photo-eye beam near the floor, and again the door must reverse. Both depend on a balanced door, which is why they come after the adjustment rather than before.
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.
