The Critical Function of Garage Door Cables
Springs provide power, and cables are the connectors that allow that power to lift the door’s weight. Lifting cables run from the bottom bracket to the drums or pulleys attached to the torsion spring shaft. The cables on each side work in unison — if one slips or breaks during operation, the door will malfunction.
Signs of Cable Failure
Each of the following four symptoms of cable fraying or failure requires a professional to see to them:
- A crooked door: The most distinct sign, one side lifts while the other stays down, causing the door to jam in the tracks.
- Loud popping: A sharp noise followed by the door falling or becoming stuck, the sound is the cable snapping.
- An off-track door: The diagonal strain on the door from a cable loss often forces the rollers out of the tracks, taking it off its tracks and compounding the damage.
- Loose wires: Fraying or loose wires are a clear sign that a cable is at risk of failing. If you see a frayed, rusting or snapped wire hanging loosely near the side rail, don’t use the door and call a professional.
The Risks of DIY — Leave Repair to the Professionals
A broken cable leaves a garage door completely unbalanced, with the remaining cable supporting an unrated load. If this second cable snaps, the door will slam shut, which is a serious safety risk. The cable’s bottom bracket is a common source of DIY mishaps as people don’t know how or that they should safely unwind the tension spring, which requires specialized training and tools.
Improper cable detachment can also cause severe injuries. The released tension can turn the cable into a high-speed whip and the bracket into a dangerous projectile.
Our Cable Replacement Process
When we arrive at your property, you can expect the following process:
- Secure and level the door: We clamp the door to prevent it from falling further before starting work.
- Inspect the drum: We inspect the cable drums for grooves or plastic wear — bad drums destroy new cables in weeks.
- Replace cables: We replace standard wires with galvanized, aircraft-grade steel cables designed to resist salt and corrosion common in Markham.
- Wind the cables: Our technicians wind the wires to ensure the door sits perfectly flat on the floor.
