- The call
- 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.

Vertical track is fixed to the jamb in one of two ways, and the assessment begins by reading which one your door has. Bracket-mounted track hangs on a few L-shaped jamb brackets, each lag-screwed into the wood, and can be shifted a little at each bracket to set spacing and plumb. Angle-mounted track uses a full-height continuous angle and is common where sideroom is tight. Either way the vertical run ends at a flag bracket that also carries the horizontal track and, on a torsion door, the spring shaft bearing. Track repair works with those fixings, tightening, replacing or repositioning them so the run sits true.

Scene 1
Overhead, the horizontal tracks should be level with each other, or set to the same pitch, held from the ceiling by back hangs of perforated angle screwed into joists. The technician sights along each run for sag, twist or a spread channel, checks the stiffening angle riveted to the track is intact, and puts weight on each hanger to check for flex. A run that droops at the rear slopes the wrong way rather than level or its intended pitch; one knocked sideways by a ladder or stored goods twists the top section as it travels. A door drifting back toward the opening once raised points to balance instead. Any hanger anchored into drywall alone is flagged for a joist.
Scene 2
When worn rollers have pried the lip of the track open, the channel is squeezed back to its original width along the affected length. The technician measures the opening against an undamaged stretch, then closes it in stages with track pliers or a clamp and block, checking with a roller after each pass. The lip is dressed so no burr remains to nick the wheel. Because the spread came from rollers dragging on one edge, the wheels that did it are replaced in the same visit, otherwise the new profile opens again within a season. The corrected length is then re-fixed to its bracket so the shape holds.
Scene 3
Before leaving, the technician tells you what the door runs on: two-inch or three-inch track, the radius of the curve, whether the layout is standard, low-headroom or high lift, and which pieces were straightened or replaced. Write it inside the cover of the door manual or on a card by the opener. Any future part, a roller, a hinge, a section of track, is then ordered to match rather than measured from scratch, and a technician years from now can read at a glance how the door was set up. If the jamb was repaired or a hanger moved to a joist, that goes on the same note.

They can, and it is one of the slower ways track goes wrong. A wheel that no longer turns on its bearing skids along one lip of the channel, and over thousands of trips that pressure pries the lip open until a roller can slip out. When a spread section is closed up, the rollers that caused it are replaced at the same time, otherwise the new profile opens again within a season.
The flag bracket is the L-shaped angle at the top of each vertical track. It ties the vertical run, the curve and the horizontal track together, and on a torsion-spring door it also carries the end bearing plate for the spring shaft. Because so much meets there, a loose or bent flag bracket throws the whole path off. The technician unloads the springs before moving it and squares it carefully when it goes back.
Yes, and the wood is part of the job. Screws will not hold in soft timber, so the technician cuts back to solid wood and sisters a new length of jamb alongside or replaces the lower section, fastening it through to the framing. The brackets are then lag-screwed into the fresh wood and the track set to the door. In older garages this repair is common, and it is what makes the alignment last.
