Commercial Cable Repair Richmond BC
A broken lift cable on a commercial overhead door usually means one side of the door drops while the other stays up — racking the door in its frame. We repair commercial door cables across Richmond same-day in most cases. Call 604-206-5727.
What Happens When a Cable Breaks
Commercial overhead doors use two lift cables — one on each side — that run from the bottom corners of the door up and around drums on the torsion shaft. When one cable breaks, that side of the door falls while the other stays held by its cable. The door racking sideways in the frame prevents it from traveling in either direction. Running the opener on a racked door bends tracks and damages the operator — do not do it. We straighten the door, replace both cables, and confirm the drums and bottom fixtures are in good shape before we leave.
Why Cables Fail
- Fraying from years of contact with the drum groove edge
- Drum groove wear that lets the cable slip off track
- Spring failure that drops the full door weight onto the cables
- Corrosion — cables in Richmond's river-adjacent industrial areas near the Fraser see salt air and moisture that accelerates wire rope fatigue
- Improper tension from a previous repair that left one cable running tighter than the other
We Replace in Pairs
We replace both cables together, every time. A cable that breaks has a partner at the same wear point. Running a new cable against a worn one creates uneven tension — the door pulls to one side on every cycle. Mismatched cable tension is also hard on rollers and tracks. Matched replacement is the only repair that makes sense.
Frequently Asked Questions
Can I operate the door with a broken cable?
No. A racked door will not travel on its tracks without damaging them further. Running the opener forces the motor against a jammed load. Leave the door in place and call us. Most cable repairs are same-day.
How long does a commercial cable repair take in Richmond?
Most cable replacements take 60 to 90 minutes on site. We carry commercial-grade lift cables in the standard diameters on the truck. If the drums are worn or the bottom brackets are bent from the drop, add time for that work.

How Commercial Door Cables Fail in Richmond
Lift cables on commercial overhead doors are under significant tension at all times — supporting 150 to 600 lbs of door weight through thousands of open-close cycles. In Richmond’s environment, cable failure is accelerated by three factors: the high humidity from the Fraser River delta, salt air from ocean proximity, and heavy cycling on Richmond’s loading dock-intensive warehousing buildings.
Fraying is the most common early failure sign. Individual wire strands in the cable begin separating, typically starting near the bottom drum or at the cable anchor point at the bottom of the door. A fraying cable that isn’t replaced will eventually snap — usually under the high tension of an opening cycle, which can cause the door to drop suddenly on one side. A door operating on a snapped cable is dangerous and damages additional components if it continues to run.
Cable drum failure is a related issue. The cable wraps around a winding drum at each end of the torsion bar. When the drum wears or the cable groove is damaged, the cable can slip off the drum track, causing uneven lifting and door misalignment. We inspect the drums on every cable replacement to confirm the groove is intact before installing new cable.
Cable Replacement Process
We always replace cables in pairs — left and right sides simultaneously. Replacing a single cable leaves an unbalanced system: the new cable is longer and has different stretch characteristics than the aged cable on the other side, which causes the door to open crooked and puts uneven stress on both the track and the spring system. Paired cable replacement adds minimal cost and significantly extends the life of the entire lifting system.
- Full-length inspection of both cables and drum condition before quoting
- Rated commercial lift cable — galvanized 7×19 aircraft cable for Richmond applications
- Proper cable termination at the anchor bracket and drum groove
- Spring tension check after cable replacement to confirm balanced lift
- Safety test — door balance and reversal test before we leave
What size cable does a commercial Richmond warehouse door need?
Most single-section commercial overhead doors in Richmond use 1/8″ or 5/32″ diameter cable. High-clearance warehouse doors and heavy-duty roll-up doors may use 3/16″ or 1/4″ cable. We size the replacement cable to match the door’s weight and spring system specifications, not just whatever was on the door previously — undersized cable is a common cause of premature failure.
Can you replace cables on a door that’s currently stuck open?
Yes. If one cable has snapped, the door typically hangs unevenly or won’t close all the way. We can safely release tension, lower the door manually if needed, and complete the cable replacement in a single visit. Call 604-206-5727 for same-day service.
