Garage Door Track Repair or Replacement in London
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.
Garage Door Track Repair or Replacement
In plain words
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.
How the visit goesThe garage floor has settled at one corner, and the door now scrapes the concrete on that side while daylight shows at the other. The track on the low side sits crooked against a jamb that has split.

How the visit goes
Rollers, hinges and top fixtures along the path
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.
Closing a channel that has spread
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.
Signs worth a call before the door jams
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.

What affects the quote
Same fees day, night or weekend
1Which part of the run
A vertical section below the curve is the simplest change. The curve itself, or the horizontal run overhead, involves the flag bracket and hangers and takes longer to set.
2Damage to sections and bottom hardware
When a bumper strike has also dented the bottom section or bent a bottom bracket, that repair is described and priced separately from the track so you can decide each on its own.
3Condition of the jamb wood
Where the jamb is soft or split at the floor, sistering or replacing the lower length is carpentry added to the track work, and the lumber and fasteners are listed on their own line.
Garage Door Track Repair or Replacement: questions
Why is the horizontal track sagging?
The horizontal run hangs from the ceiling on back hangs of perforated angle, and it sags when a hanger bends, its screws pull out of a joist, or it was only ever fixed into drywall. A sagging hanger droops that run out of level or its intended pitch. The fix is a straight or new hanger screwed into solid framing, with the run set to the manufacturer's specified pitch and matched to its partner; a door that drifts back toward the opening once raised is a separate, balance-related symptom.
What does track radius mean, and does it matter for a replacement piece?
The radius is the size of the curve where the track turns from vertical to horizontal, typically 12 or 15 inches on two-inch residential track. It fixes how high the door climbs before it turns and how much headroom is needed, and the cable drums and spring setup are chosen around it. A replacement curve has to match the other side, otherwise the door meets the horizontal run at different heights and twists as it opens.
What if the car hit the door as well as the track?
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.
