Frayed, slack, and snapped lift cables replaced and re-seated on the drums.
What's involved
Garage Door Cable Repair
Lift cables connect the bottom of the garage door to drums at the ends of the torsion shaft. They are what translate spring torque into an even upward pull on both sides of the door. Cable repair addresses fraying wire, a cable that has slipped off a drum, incorrect routing, damaged bottom fixtures, and the track or balance faults that led to cable trouble. A loose cable is also a symptom. We inspect why tension changed before restoring the cable path and leveling the door.

Symptoms
Signs You Need This Service
- One cable hangs loose beside the vertical track.
- The door lifts higher on one side than the other.
- Thin wire strands are sticking out from the cable.
- The bottom corner of the door is pulled away from the track.
- The cable is wrapped unevenly around the drum.
Repair or replace?
Cable life varies with door alignment, moisture exposure, spring condition, and how often the door runs. A cable with intact strands and correct drum wraps may remain serviceable; visible fraying, kinks, corrosion, or a damaged end fitting are replacement signals. If a cable has slipped because a spring broke or a track binds, correcting cause prevents the replacement cable from repeating the failure.

Root causes
What Actually Goes Wrong
Cable drum slip
A cable can leave its drum when the door moves unevenly, the shaft shifts, or tension is lost during a bind. Once the cable overlaps or unspools, the door no longer receives equal lifting force on both sides.
Frayed cable wire
Repeated bending over drums and exposure to moisture can break individual wire strands. Fraying weakens the cable and creates sharp strands that catch on hardware, making an otherwise small defect progress quickly.
Bent door track
A roller that binds in a bent track can make one side lag behind. The cable on the other side continues to wind, changing tension until a cable loosens or comes off its drum.
Failed lift spring
When a torsion spring breaks, the shaft can no longer keep the cables properly tensioned. The door may drop unevenly and a cable can unwrap, even though the cable itself was not the original failure.
Local conditions
Why This Matters in Mississauga
De-icing brine and road salt can be carried into a garage on winter tires, then dry onto low steel hardware near the door. In Mississauga, that exposure can accelerate corrosion on cables, bottom fixtures, and the lower track long before upper hardware looks weathered. A quick visual check for broken cable strands or orange residue at the bottom corners is worthwhile every winter season. Cleaning salt residue helps, but it does not make a frayed cable safe to keep using.
Safety
What to Handle Yourself
Treat a loose or frayed lift cable as a high-risk condition. Cables are tied directly to spring tension, and bottom brackets are under load when the door is closed. Do not grab a dangling cable, cut off frayed strands, remove a bottom bracket, or try to wind the cable back onto its drum. The door can shift or fall while the cable is handled. Keep the opening clear and book cable service online for email confirmation.
The visit
How We Work Through It
-
Stabilize door
We secure the door before touching the cable system. The opener is disconnected when necessary so it cannot pull against a crooked door or create more uneven tension.
-
Trace root cause
Cables, drums, bottom brackets, springs, shaft bearings, rollers, and tracks are inspected together. This shows whether the cable failed, slipped, or was pulled out of position by another fault.
-
Restore cable routing
A serviceable cable is seated correctly or a damaged cable is replaced. The drums are aligned and both sides are set to carry equal tension as the door moves.
-
Confirm level travel
We operate the door manually through its range, watching cable wraps and bottom corners. The opener is checked afterward to ensure its arm is not masking a remaining balance issue.
Questions
Garage Door Cable Repair FAQs
Can I put a loose cable back on the drum?
No. A loose cable is connected to a loaded counterbalance system, and it may have come off because the door is crooked, the spring failed, or the track bound. Simply rewinding it can trap the original problem. The reason for lost tension must be identified before cable routing is restored.
Are a few broken cable strands important?
Yes. Broken strands reduce cable strength and create sharp ends that can snag on the drum or bracket. The remaining strands then carry more load and can fail progressively. Do not touch or tape it; book an inspection before the cable becomes a complete break.
Why is my garage door crooked after a cable issue?
The two cables must pull evenly for the door to rise level. When one cable loosens or comes off the drum, the opposite side can keep moving while the affected side stays down. Continued opener use may twist panels and damage rollers, so stop operation.
Does cable repair include checking the spring?
It should. The spring supplies the tension that keeps lift cables seated on their drums, so a cable repair without balance inspection can miss the main cause. The shaft, drums, bottom brackets, track alignment, and manual door travel matter in practice to a lasting correction.
