- 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.

The bottom foot of a garage door track has a hard life in this climate. Slush and salt drip off the car and pool exactly where the bottom rollers sit, the jamb brackets and channel rust and thin, and a ridge of ice at the threshold can stop the door short while the opener keeps pulling. Winter track repair often means replacing the lowest section of vertical track and its brackets, sistering a jamb that has gone soft at the floor, and refixing everything into sound wood. A clear threshold and a look at the brackets each spring keep the new steel in good shape.

Garage Door Track Repair or Replacement · Mississauga

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
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
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.

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.
