Broken Garage Door Cable Repair — Toronto & GTA

Q: Can I open my garage door manually with a broken cable?

No. With a broken cable, the door is unbalanced and will drop on one side without the cable tension to support it. Attempting to manually lift the door risks injury and further damage to tracks, rollers, and the door panels themselves. Leave the door in its current position and call 437-265-9995 for emergency service.

Q: Cable snapped on one side — why does the door sag?

Garage door cables run from the bottom corner brackets up to drums on the torsion shaft, carrying the weight transferred from the spring. When one cable snaps, that corner of the door loses support and sags or drops. The door cannot operate safely until both cables are replaced and the system is re-balanced.

Q: How long does cable repair take?

Cable and bracket replacement typically takes 45 to 60 minutes on-site. Combined with our 45-90 minute dispatch time, most GTA customers have their door working within 2 hours of calling 437-265-9995.

Q: Are cables replaced in pairs?

Yes. We always replace both cables at the same time. Cables wear evenly as a pair, and if one has snapped, the other is near failure. Replacing both prevents a repeat call shortly after and ensures even load distribution.

Q: How do I know if it's the cable vs. the spring?

Both a broken spring and a broken cable can cause a door that won't open or sags. Key difference: a broken spring usually produces a loud bang and the door lifts a few inches then stops. A broken cable is quieter — the door may sag visibly on one side, or you may see a loose wire hanging at the door corner. In many cases both fail together. Our technician diagnoses the exact cause on arrival — the FREE service call covers the diagnostic.

Q: Does cable repair include bracket replacement?

Our cable repair service includes inspection of the bottom brackets. If a bracket is bent, cracked, or pulled out of the door, it is replaced as part of the job. The $150-$220 price covers cables, brackets, and hardware needed to restore proper operation.

Cable and bracket repair costs $150–$220 (both cables replaced, hardware included), with a FREE service call and no extra charge for nights, weekends, or holidays. 1-year warranty on all work.

What Your Garage Door Cable Does

The two lift cables run from the bottom corner brackets of your door, up to drums on the torsion bar above. They transfer the spring’s counterbalancing force to the door, allowing a 200–400 lb door to feel weightless when lifted. When a cable snaps or unravels, the door immediately becomes unbalanced and dangerous.

Signs of a Broken Cable

Door sags on one side
Visible loose wire at the door corner
Door feels extremely heavy on one side
Door opens unevenly or jams in tracks
Grinding noise during operation

Why It's Unsafe to Use

With one cable broken, the full door weight shifts to the intact side and the remaining cable. This can cause the door to drop suddenly, damaging your vehicle, the door itself, or injuring anyone beneath it. Stop using the door immediately and call 437-265-9995.

The Fix

Both cables replaced, bottom brackets inspected and replaced if needed, door re-balanced and tested. Takes 45–60 minutes on-site. Cost: $150–$220 all-in including parts and labour.

Do Not Attempt DIY Cable Repair

Garage door cables are under enormous tension from the torsion spring. Handling them without releasing spring tension first — and without the correct tools and training — can cause the cable to snap back violently or the door to drop suddenly. This is a professional repair. Call 437-265-9995 and our technician will arrive in under 90 minutes, 24 hours a day.

Cable Failure vs. Spring Failure — Key Differences

Symptom	Broken Cable	Broken Spring
Sound when it breaks	Quiet / soft snap	Loud bang (like gunshot)
Door appearance	Sags on one side	Won't open at all
Visible damage	Loose wire at corner	Gap in coil above door
Often occur together?	Yes — a broken spring can snap the cable too. Our technician checks both.
