- The call
- Halfway up, the door lurches and one roller rides onto the lip of the channel. Near the curve the track looks wider than the rest, and the door hesitates in the same place on the way down.

The door has started rubbing the frame on the left, leaving a shiny stripe down the weatherstrip. Looking closely, the bracket near the floor stands a finger's width off the wood, its screws half out.
What you get back is a door that runs its full height without a catch, hesitation or bang, with every roller seated in its channel and both sides rising together. The track sits plumb and firm on the jambs, the horizontal runs hold level from solid hangers, and the door seals along the stop when closed. Because the track was set to the door and the springs re-tensioned to it, the door balances by hand and the opener works lightly. You also leave with a note of the track profile, radius and lift type, which makes any later part a simple match.

Scene 1
The curved piece where vertical meets horizontal takes the door's weight at the moment its direction changes, and it is the part least forgiving of a bend. The technician checks the curve for flattening, a twist or a kink, and confirms both sides share the same radius. Above it sits the flag bracket, the L-shaped angle that ties vertical track, horizontal track and, on a torsion door, the end bearing plate together. A loose or bent flag bracket shifts everything it holds, so its fasteners and squareness are checked with particular care, and the technician notes that the springs will be unloaded before that bracket is moved.
Scene 2
A door that has been catching on bad track usually has a few parts that suffered with it. Rollers with flat spots or bent stems are replaced, hinges that split when the door twisted are renewed, and top fixtures knocked out of line are reset so the top roller sits at the right depth. Each roller is confirmed to turn and slide freely. The channel is wiped clean of grit and old grease, and the moving parts are lubricated to the door's own manual, since track advice varies by maker. Attending to these pieces while the door is held and the track is fresh saves a second visit and stops the new alignment being chewed up by the old damage.
Scene 3
If the visit included repairing the jamb, you now have sound timber behind every bracket, and the small habits that keep it that way are simple. Keep the bottom of the jamb dry: slush pushed clear, a bead of exterior caulk where the trim meets the slab, and paint or stain kept up on the exposed face. Look once a year for the tell-tale dark, soft patch at floor level and for screws that seem to have moved. A jamb that stays dry holds lag screws for decades, and with the track now fixed into good wood, the alignment set today has something solid to rest on.

FeesSame any hour
The horizontal run hangs from the ceiling on back hangs of perforated angle, and it sags when a hanger bends, its screws pull out of a joist, or it was only ever fixed into drywall. A sagging hanger droops that run out of level or its intended pitch. The fix is a straight or new hanger screwed into solid framing, with the run set to the manufacturer's specified pitch and matched to its partner; a door that drifts back toward the opening once raised is a separate, balance-related symptom.
Often, yes, and it is a track job with a spring job attached. Low-headroom dual track lets a door open under a low ceiling or a beam, while high-lift track carries the door further up the wall to clear a car lift or storage. Each changes the horizontal run, the curve, the top fixtures and usually the cable drums and spring turns. The technician measures headroom, sideroom and backroom first and confirms the door suits the change.
Sometimes. The flag bracket at the top of the vertical track usually carries the bearing for the torsion shaft, so if that bracket or the curve has to move, the springs are unloaded first with winding bars and rewound afterwards to the same turns. Simple work on the vertical run below the curve, or on the horizontal hangers, can often be done with the springs left alone. Either way the door is balance-tested at the end.
