- The call
- Backing out this morning, the mirror caught the track beside the door. Now there is a crease in the steel at about knee height, and the door stops with a bang every time a roller reaches it.

You bought the house with a door that sticks near the top of its travel. The vertical track was screwed tight against the jamb, so the door drags along its stop moulding on every trip instead of swinging clear.
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
With the door held, the technician works along both sides checking how each roller sits. A roller should rest in the channel without being pinched, and its stem should turn and slide in the hinge or bracket that carries it. A stem that is stuck, a wheel riding up on the lip, or a roller that has popped free are signs of a spread or misaligned section nearby. Worn wheels are also a cause rather than just a casualty, since a roller that no longer rolls drags on the track edge and slowly opens it. The top fixtures are checked for bending, and hinges for splits, so the parts that guided the door into trouble are corrected with the track.
Scene 2
With the pieces in place, the technician sets the track to the door rather than to the wall. Each vertical run is plumbed, the gap to the door edge is matched side to side, and the top of each run is eased away from the jamb by the small amount that lets the door seal at the stop when closed and release on opening. The horizontal runs are levelled to each other and squared to the verticals, and the distance between the two tracks is checked at the floor, at the curve and at the rear so the door is neither pinched nor loose anywhere in its travel. Every bracket is then tightened in that position.
Scene 3
The lowest foot of vertical track and the bracket beside it are where winter does its damage, so a little attention there pays off. Push slush away from the inside edge of the door rather than letting it pool against the track, and when a mild day comes, rinse or wipe the road salt off the bottom brackets and the channel. A dab of silicone spray on the jamb bracket fasteners in late autumn helps them shed meltwater. Keep the threshold clear of packed ice so the door meets the floor, not a ridge, and the opener never pulls against a stuck door. Those habits are what keep replacement track from meeting the fate of the last set.

Then the assessment covers both. A bumper that creases the track usually dents or bows the bottom section, and can bend the bottom bracket, the roller stem and a hinge. The technician follows the impact through those parts, straightens or replaces the track, and explains separately what the section and its hardware need, whether that is a strut, a bracket, or a replacement panel. The door is only put back to work once the whole path is sound.
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 track is under load from the door resting in it and, at the top, from the spring shaft on the flag bracket, so working on it means securing the door and sometimes unloading the springs first. Freehand hammering also tends to push a dent into a ripple that a roller feels even more. The technician clamps the door, shapes the steel in small steps with a block or track pliers, and gauges the result with a roller.
