Garage door track repair is the realignment, straightening, or replacement of the steel rails that guide the door's travel — addressing bent tracks, misaligned brackets, loose mounts, and off-track doors typically completed in 60–90 minutes for $180–$350 in London, Ontario.
Vehicle impact, harsh winters, and aging brackets all bend tracks. We straighten what we can, replace what we can't, across London, Byron, Masonville, and Hyde Park.
Not every bent track means a full replacement. Here's how we decide on-site, and what each level typically costs. Most homeowners are surprised how often a quick straighten is all it takes.
Under 1/2 inch flex. Steel still has a clean curve, no creasing. We straighten on-site with hydraulic tooling in 60 minutes. Lifetime warranty on the work.
1/2 to 1 inch flex. Borderline — depends on whether the radius curve is intact and how many bend cycles the steel has seen. We assess and recommend on-site.
Over 1 inch flex, or steel is creased (kinked, not curved). Replacement is the only safe option — straightened creased steel fails again within months.
Track problems show up as binding, scraping, or misalignment. Six common patterns — and what each one usually means.
Smooth travel except at one point where it sticks. Almost always a bent track section in that exact spot.
Daylight visible between roller and rail. Track has flexed away from the door — usually loose brackets or impact damage.
Roller dragging against bent rail edges. Continued use damages both the rollers and worsens the bend.
Stops at any height with one side higher. Track misalignment, not necessarily a spring problem.
Rusty mounting bolts, drywall cracking around brackets. Vibration over years loosens fasteners.
Backed into a track, even at low speed. Steel bends, brackets shift, alignment is gone. Catch this early.
The track system has three sections: vertical track (floor to ceiling, on both sides of the opening), horizontal track (across the ceiling, holding the door when open), and the radius curve connecting them. Any section can bend or misalign, and each repair has different complexity.
Most track issues are repairable rather than full-replacement. A track with a single dent or a 1/4-inch flex can often be straightened on-site. Significant kinks or damaged radius curves require section replacement. Loose brackets are usually a 30-minute fix.
The judgment call comes down to steel integrity. Galvanized steel can be straightened once or twice without significant strength loss. Three or more bend cycles, or any visible kinking (creased steel rather than smooth bend), and the section needs replacement. Trying to keep operating a kinked track damages rollers, stresses cables, and risks sudden failure.
The economics also matter. A realignment is $180–$240 with the same lifetime warranty as new. A section replacement is $240–$350 per side. Replacing both verticals is $380–$560. We're a repair-first shop because in the long run, that's what builds trust — and because most bent tracks genuinely are fixable.
Most original installations used decent hardware but didn't always hit the framing studs — especially in older garages where finished drywall went up first and the door hardware after. Over years of opening cycles, those bolts back out a fraction of an inch each year. By the time you notice, the bracket is barely holding.
We re-mount with grade-8 lag bolts, locating studs with a finder, and adding additional brackets if the original layout is undersized. If the underlying framing is rotted (a real issue near outdoor-exposed corners), we'll flag that and recommend the right next step — sometimes a sister-stud, sometimes a referral to a carpenter.
Vehicle impact is the leading cause we see. Track guards — bolt-on steel plates protecting the bottom 12 inches of vertical rail — cost $80 installed and prevent at least one fix in the door's lifetime. They're the single best preventive upgrade. (Door & Access Systems Manufacturers Association installation standards, 2024)
The leader. Even at 5 mph, backing into a track section bends steel that won't return to true. We see this most often around Halloween and Christmas — kids' bikes left out, parents reversing in winter darkness.
The slow-motion cause. Garage doors generate constant vibration. The lag bolts holding tracks to the framing slowly back out over years. By the time you notice the flex, the realignment job is bigger.
When a door jumps the rails — usually after a spring or cable failure — the rollers grind against the track edges as it falls. Even brief contact at door weight bends the steel.
Frozen bottom seals locking the door to the floor force the opener to pull harder, stressing the tracks. Snow loads on horizontal sections from leaky garages do the same. Both are seasonal in London.

Marked van with track sections, brackets, mounting hardware, and rollers stocked.
Tech inspects all tracks, brackets, and rollers — confirms scope and fixed price. You approve before any work.
Tracks straightened or replaced, brackets retorqued, full door cycle test. Lifetime warranty on parts replaced.
Backed into the track in November (don't ask). Door wouldn't close right after. Tech straightened the bend in 40 minutes for $190 — quoted me $400+ at another shop for full replacement.
Bracket pulled half out of the wall after 18 years. They replaced both vertical brackets, retightened the entire track system, fixed two loose roller stems I didn't even know about. $220 well spent.
Heavy snow load bent the horizontal track last February. They got us in two days later, replaced the section, plus added a reinforcement bracket so it wouldn't happen again. Smart fix, fair price.
