- 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 track is the pair of steel channels that guide every roller on a sectional garage door: a vertical run fixed to each jamb, a curve overhead, and a horizontal run hung from the ceiling. Track repair puts a bent, spread, loose or corroded run back to the shape and position the door needs, and replacement renews the pieces that are beyond straightening. The technician secures the door, measures the track against the door and its lift type, corrects or replaces what is damaged along with its brackets and fasteners, and finishes with a balance and travel test so the door runs squarely again.

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
Overhead work starts with the springs unloaded, since the flag bracket carrying the end bearing plate has to come loose for the curve to change. The technician fits a curve of the same radius so the door meets the horizontal run at the same height, then hangs a new or straightened horizontal track from back hangs screwed into joists, not drywall, with a stiffening angle along its length. The rear of each run is set level with its partner, or to the same pitch, and square to the vertical track, and the two hangers are adjusted until a straightedge across the pair reads true. A bent hanger is replaced rather than bent back.
Scene 3
A well-set track stays that way, but doors live busy lives, and a few early signals mean an easy adjustment instead of a stuck door. A new rub mark on the weatherstrip, a roller that squeaks at the same point each trip, a door that starts to lean or that closes with a gap at one corner, a bracket with a shadow behind it, or a horizontal run that looks a shade lower than its partner: any of these is the track beginning to move. Mention what you saw and where, and the technician can usually put it right in a short visit. Catching it early also spares the rollers and hinges the wear a misaligned track hands them.

It is galvanized steel folded into a channel that the roller wheels ride in. Residential doors almost always use two-inch track, with three-inch reserved for heavier or wider doors. The curved piece comes in a radius, commonly 12 or 15 inches, that sets how much headroom the door uses. Replacement pieces are ordered to the same profile, gauge and radius as the rest of the set.
A catch that repeats in one place is the signature of a local track fault: a dent, a spread section, a step at a joint, or a bracket that has let the track drift. Each roller reaches the flaw at the same point in the travel and bumps over it. The technician finds the spot by running a roller through the channel by hand, then dresses or replaces that length and checks the rest of the run for the same problem.
It is the follow-on. Putting a door back on its track deals with the rollers and gets the door running again; track repair deals with the reason it left. If the reset showed a spread channel, a bent section or loose brackets, those are corrected now so the rollers stay put. Where nothing on the track was at fault and the cause was a cable or an obstruction, the track is simply checked and confirmed.
