Garage door cable and track repair is the replacement of frayed or snapped lift cables, bent or misaligned tracks, worn rollers, and damaged hinges that cause doors to bind, stick, or fall off-track — typically completed in 60–90 minutes for $150–$350 in London, Ontario.
Same-day repair for off-track doors, snapped cables, bent rollers, and broken hinges across London, Byron, Masonville, and Hyde Park. Lifetime parts warranty included.
Most homeowners think of their garage door as one thing. It's actually four moving systems sharing the same frame: cables that lift, rollers that glide, tracks that guide, and hinges that flex. When one fails, the others get stressed past design.
That's why a snapped cable usually means worn rollers too. And why a bent track usually leaves at least one hinge cracked. We always inspect all four during a service call — even if you only called about one.
Cable and track problems show up as a door that won't close evenly, slams when it should glide, or sits crooked in the opening. Six common patterns — and what each one usually means.
One side higher than the other, or the door has popped out of the side track entirely. Don't operate — running an off-track door tears the rollers and bends the rails further.
A frayed or fully snapped lift cable dangling near the bottom of the door. Often happens just after a spring breaks — both fail together.
Door drops the last 6–12 inches instead of gliding. Cable has slipped off the drum, or one cable is broken. Stop using until inspected.
Loud grinding, popping, or scraping along the tracks. Worn nylon rollers (or rusted steel rollers) bumping along damaged track.
Stops mid-travel, requires force to keep going. Usually a bent track section or a hinge that's torn loose between two panels.
Brown rust streaks, daylight visible between track and frame, or the track has pulled away from the wall. Brackets need re-mounting.
These parts work together as a system. The springs store the lifting energy. The cables transfer that energy from the springs to the bottom of the door. The tracks guide the door up and over. The rollers reduce friction along the way. The hinges let the panels articulate around the curve. When one component fails, the others get stressed beyond design — which is why a snapped cable usually leads to a crooked door, and a worn roller usually leads to track damage.
The good news: most cable and track repairs are quick. We carry standard cables, rollers, and 7-foot track sections on every truck. Off-track resets take 30–45 minutes. Cable swaps take 45–60 minutes. Full track replacements take 90 minutes per side.
Cables are 1/8" galvanized steel braided wire, rated for around 4,000 cycles before fatigue. They live in a hostile environment — exposed to road salt in winter, condensation in summer, and constant flexing. The first sign of trouble is a few broken outer strands; the next stage is rapid fraying; the last stage is full failure.
If you see any visible fraying, replace before failure. A snapped cable while the door is moving can whip across the garage at high speed — exactly the same risk as a spring failure. (Door & Access Systems Manufacturers Association safety guidance, 2023)
The track is essentially a rail. The rollers ride in it on both sides. As long as the door's weight is balanced (springs and cables doing their job) and the rollers are intact, the door stays in. Disrupt any of those, and the door pops out — usually on one side first, then twisting the whole assembly out of alignment.
Common triggers in London: winter ice buildup at the bottom seal locking the door down, vehicle bumps at the bottom panel, and spring failures that drop the door uncontrolled. We've seen all three many times this year.
The most underrated upgrade for an aging garage door: nylon ball-bearing rollers. The cheap steel rollers that come with most builder-grade doors are loud, prone to flat spots, and chew up the tracks over time. Quality nylon rollers ($18 each, $180 for a full set installed) cut noise by 60–70% and last 15+ years.
Hinges are the unsung heroes — they let the panels articulate around the radius curve. A cracked or bent hinge causes the panels to flex unevenly, which over time cracks the panels themselves. We replace them whenever we see visible cracks, usually 2–3 hinges at a time at $25 each installed.

Tech inspects the full door system, isolates the fault(s), confirms fixed price. You approve before any work begins.
Cables, rollers, or track sections replaced. Door rebalanced and tested across full travel. Lifetime warranty included.
Cable snapped Saturday morning, door stuck halfway open. Tech showed up at noon, replaced both cables and gave me new rollers for $230. Quieter than the day we bought the house.
Backed into the garage door (don't ask). Bottom panel bent, door off-track. They reset it, replaced two hinges, ordered the panel — temp fix held up perfectly until panel arrived. Saved my weekend.
Door was screaming every time it moved. Booked a quick service call, tech swapped all 10 rollers in 40 minutes. Sounds brand new. Should have done this years ago.
