Warning signs of a failing garage door cable
The two lift cables do the actual holding. Each one is anchored to a bracket at a bottom corner of the door and wraps onto a grooved drum on the shaft overhead. Signs one is giving out:
- The cable has jumped its drum. Look up at either end of the spring shaft. If the cable is spilling over the drum's edge or hanging in a loop, it has come unwound.
- One bottom corner leads. When the door opens or closes, one side moves ahead of the other, or the door stops at an angle partway.
- Broken strands that catch the light, usually in the last few centimetres above the bottom bracket.
- A bottom bracket that looks more orange than silver, or whose bolts are rusted into the door's bottom section.
- A clunk or a jolt at the bottom of travel, or the door shuddering on its way down.
- A spring broke recently. The sudden slack can kink a cable or knock it off the drum, even if it looks fine at first glance.
Don't use the door until it's fixed. One cable can't hold the door square, so the panels twist in the tracks and rollers can pop out. The bottom bracket is also held under spring tension. Unbolting it yourself is how people get hurt.
What wears out cables in Nepean
Salt carried in from main roads. Many Nepean driveways empty onto busy, heavily salted roads: Merivale, Baseline, Woodroffe, Greenbank, Fisher and Prince of Wales. All winter, salty slush falls off the car and melts against the garage door's bottom seal. That's exactly where the bottom brackets sit, so they rust first, and the cable loop attached to them follows.
Older doors with original hardware. Nepean has homes from several eras, from the 1960s homes in Qualicum to Craig Henry (built from 1971) and Centrepointe (from 1984). On older doors that have never had their hardware replaced, decades of winters have worn the factory bottom brackets well past their best. Even when the door panels still look fine, the hardware at the bottom corners can be badly rusted.
Spring breaks that throw cables off. When a torsion spring snaps, the cable tension drops instantly and the cable can slip off its drum. If the opener runs after that, the slack cable can tangle, fray or kink. Many cable repairs we do start as a spring problem, which is why we check both. (See spring repair in Nepean.)
Worn or cracked drums. On a worn or cracked drum, the cable no longer sits in its groove and can jump out under load. Putting a new cable on a bad drum only buys a short time.
Daily use as the front door. For households that come and go through the garage several times a day, maybe heading to the Nepean Sportsplex or running errands along Merivale, the cables flex over the drums with every cycle. Wear adds up fastest at the drum end and at the bottom bracket.
Before and after: replacing a rusted bottom bracket in Nepean
The "before" photo under the video shows the hardware we took off a Nepean door. The old bottom bracket and roller were so rusted they were barely recognizable, and the lift cable was still attached to them. When a bracket gets this bad, the cable that loops around it can't be trusted either, so we replaced all of them together.
The "after" photo in the next section shows the new galvanized bottom bracket, with its "warning: under tension" label, and the new roller installed. The cable drum is visible above. Galvanized steel holds up much better against the salty meltwater that sits on a Nepean garage floor all winter.
What a Nepean cable repair involves
- We arrive from close by. Our Larkspur Drive shop stocks cables, bottom brackets, rollers and drums, so the parts are usually already on the truck.
- Lock the door in place. We clamp it in the tracks so it can't drop or swing out.
- Look over the whole lift system. We check both cables, both drums, the springs, bottom brackets, rollers and how the door sits in the tracks.
- Written quote, approved by you before any work begins.
- Release the spring tension with proper winding bars, so the cables and brackets can come off safely.
- Fit new cables in pairs, plus new galvanized bottom brackets and rollers wherever the old ones are rusted. If a drum is cracked or its grooves are worn, we replace it too.
- Wind both drums evenly and re-tension the springs. The bottom of the door should meet the floor level along its whole width.
- Balance check and opener test. The door should hold steady halfway up by hand. Then we set the opener's force and travel, check auto-reverse, and lubricate rollers and hinges.
Most cable and bracket jobs take 45–75 minutes.
