Commercial Garage Door Cable Repair — Vancouver & Lower Mainland
Lift cables on commercial overhead doors carry the full door load every time the door moves. When a cable frays, slips off the drum, or snaps, the door either jams or — on a spring-assisted door — drops fast and hard. We repair and replace lift cables on sectional commercial doors, rolling steel doors, and high-lift systems across Greater Vancouver. Call 604-206-5727.
What Causes Commercial Cables to Fail
Cable failure on commercial doors almost always comes down to one of three things: corrosion from loading dock spray and moisture, fatigue from years of cycling, or a door that went out of balance and put extra load on one cable. Cables that sit in the drum groove without lubrication also develop wear points at the same spot on every cycle. Once you see fraying — even a few broken strands — the cable is done. A strand-by-strand failure is not how they fail in practice; they let go all at once.
We always replace cables in pairs. A cable that broke means its partner ran the same number of cycles under the same conditions. Installing one new cable against a worn partner creates uneven tension, which immediately starts pulling the door off-track.
Cable Off the Drum
A cable that jumped the drum groove without breaking is a faster fix than a snapped cable, but it still requires proper diagnosis. Cables come off drums because of a broken spring putting the system out of tension, a drum that worked loose on the shaft, or a door that racked and let one side go slack. We find the cause before re-hanging the cable — otherwise it comes off again within days.
High-Lift and Vertical-Lift Systems
Many commercial warehouse doors use high-lift or vertical-lift track configurations to maximize ceiling clearance. These systems run cables at steeper angles and through additional sheaves, which creates different wear patterns than standard horizontal-track doors. We carry the correct cable gauges and lengths for high-lift setups and can handle the sheave and bracket work that goes with them.
Signs You Need Cable Service
- Visible fraying — broken wires sticking out from the cable braid
- Cable slack on one side with the door closed
- Door tilts or one side drops faster than the other
- Cable off the drum — coiled on the floor beside the door
- Grinding or scraping noise on the way up — cable rubbing a bracket
- Door stopped moving mid-cycle and will not restart
Frequently Asked Questions
How much does commercial garage door cable repair cost?
Cable replacement on a standard commercial sectional door runs $200 to $400 for a pair including labour. Larger doors, high-lift systems, or cables that caused secondary damage to drums or hardware will cost more. We inspect and quote before starting.
Can I run a commercial door with a frayed cable?
No. A frayed cable can snap during operation, causing the door to drop suddenly on whatever is underneath it. On a loaded dock door, a sudden drop is a serious safety event. Take the door out of service and call for repair.
How long does cable replacement take on a commercial door?
A straightforward cable replacement on a two-car or single-bay commercial door takes about an hour. Larger doors with high-lift track systems or secondary damage may take two to three hours. We confirm timing when we assess the door.
