Garage Door Track Repair or Replacement
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
What you get back is a door that runs its full height without a catch, hesitation or bang, with every roller seated in its channel and both sides rising together. The track sits plumb and firm on the jambs, the horizontal runs hold level from solid hangers, and the door seals along the stop when closed. Because the track was set to the door and the springs re-tensioned to it, the door balances by hand and the opener works lightly. You also leave with a note of the track profile, radius and lift type, which makes any later part a simple match.
How the visit goesYou 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.

How the visit goes
Jamb brackets, lag screws and the wood behind them
Every fixing along the vertical track is tested by hand and by eye. Jamb brackets that rock, lag screws that turn without tightening, and a continuous angle standing off the wood all mean the track has been free to move. The technician then looks at the jamb itself, probing the bottom foot for softness where splash and salt have soaked in, and checking for splits around the screw holes. In an older garage the wood is often the real fault, and no amount of tightening holds a screw in punky timber. Where that is the case, sistering or replacing the lower jamb goes onto the plan alongside 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.
Jamb wood that will hold a screw again
If the visit included repairing the jamb, you now have sound timber behind every bracket, and the small habits that keep it that way are simple. Keep the bottom of the jamb dry: slush pushed clear, a bead of exterior caulk where the trim meets the slab, and paint or stain kept up on the exposed face. Look once a year for the tell-tale dark, soft patch at floor level and for screws that seem to have moved. A jamb that stays dry holds lag screws for decades, and with the track now fixed into good wood, the alignment set today has something solid to rest on.

What affects the quote
Same fees day, night or weekend
1Low-headroom or high-lift hardware
Changing the layout, rather than repairing the existing one, brings new horizontal track, curve pieces, top fixtures and often drums and spring adjustment, and is quoted as a separate scope.
2Track profile and radius
Two-inch track in a 12-inch or 15-inch radius is stock for most residential doors; three-inch track, unusual radii and high-lift pieces are ordered to the door and priced as such.
3Access and storage around the track
Shelving, a workbench or a ceiling full of stored goods around the horizontal run slows the work. Clearing the area beforehand changes the time quoted.
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.
