- 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.

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
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 kinked, cracked or rust-thinned vertical track comes off in one piece. The jamb brackets or continuous angle are unbolted, the old track is lifted clear with the rollers eased out of it, and the new piece, cut or ordered to the same height, profile and mounting style, is bolted to the brackets. The joint with the curve at the flag bracket is aligned so a roller passes with no step, and the track is offered up to the jamb, set plumb with the correct spacing and taper, and lag-screwed into sound wood. The rollers are threaded back in as the door is released from its clamps a little at a time.
Scene 3
Most creased tracks are met by a bumper or a mirror, and most bent horizontal runs by a ladder, a bike or a shelf. It is worth walking the garage after the repair and noticing what sits close to the track: move the recycling bins and the hockey bags a hand's width further in, hang nothing from the back hangs, and leave the horizontal runs clear of stacked boxes. Inside the car, a strip of tape on the floor or a tennis ball on a string marks where to stop. None of this is a chore, and it addresses the single most common reason a straightened track needs straightening again.
What shapes the quoteErin Mills Garage Door Experts
FeesSame any hour
Both happen, and the damage decides. A shallow dent in the vertical run away from the curve is usually dressed back to shape with track pliers or a block, and a channel that has spread can be squeezed closed. A kink, a crack, a bend in the curved piece or steel thinned by rust is replaced with a matching section, because a hard spot in the roller path keeps catching however carefully it is worked.
It is better to leave the door where it is and use another way in and out. An opener pushing a door through a damaged section pulls rollers out of the channel, twists the top section and can turn a small dent into a jammed door off its track. Industry guidance after any impact is to stop operating the door and have it assessed. Leaving it still keeps the repair small.
That gap is intentional. The rollers sit on stems that reach out from the hinges, and the track stands a set distance from the door so the wheels ride in the channel without the door's edge touching the track. The gap should be equal on both sides and slightly larger at the top of the vertical run, which is the taper that lets the door seal at the stop and release on opening. Unequal gaps are a sign the track has moved.
