A spring broke and now a cable is off too
Very common — the shock of a spring failure takes the cable with it. Both get replaced together, with the spring pair as the actual cause.

Cable Repair in Kelvin
Garage door cable repair in Kelvin
Kelvin is a modest, established residential pocket on Sandton's eastern side, with a high proportion of original housing stock. Original tip-up doors are still common here, and the extension springs and pivot bushes they use wear differently to the torsion systems on newer doors.
That is the context garage door cable repair in Kelvin happens in. Cable and bracket corrosion is the recurring theme on older properties in this area, where the door line often sits at the low point of the driveway and water stands against the bottom of the door after rain.
This page covers what that means in practice — the faults we actually attend here, how the job is diagnosed and priced, and how quickly a technician reaches Kelvin. For the subject in full, see our garage door cable repair guide; for everything else we do here, see garage door services in Kelvin.

Scope of work
What garage door cable repair in Kelvin covers
Cable work is always paired work. Both cables are replaced together and both drums are reset, because a new cable running against an old one produces exactly the uneven winding that caused the failure in the first place.
Where a door is genuinely at the end of its life, we would rather say so than sell another spring set. A perforated bottom section has lost its stiffness and no repair restores it — and that is a different conversation to a door that simply needs its balance corrected.
- Both lift cables replaced as a matched pair, at the correct diameter and length for the door
- Spring tension rechecked, since a cable failure is often a spring symptom
- Cable drums released, cleaned, inspected and re-wound so both sides run level
- Tracks and rollers inspected for the damage a skew door causes
- Bottom brackets checked — they anchor the cable and they are under full door load
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Kelvin carries the same 12-month workmanship warranty as the rest of the footprint.
Real situations
What Kelvin customers describe, and what it usually means
These are the calls we take most often from Kelvin and the surrounding Sandton area.
I can see broken strands near the bottom of the cable
Fraying at the bottom bracket, where the cable bends most sharply. Replace both cables now. Fraying accelerates once strands start breaking.
The door closed on a bin and now it runs crooked
The cables went slack on the obstruction and one has ridden out of its groove. The classic cause. It needs the tension released and both drums re-set, not a tug.
There is a loose cable hanging inside the garage
The cable has come off its drum or broken at the anchor. Do not pull it or try to re-wind it — the drum is on a shaft under spring tension.
Cables explained
How lift cables work and why they fail in Kelvin
When a cable failure is really a spring failure
Cables and springs fail as a system. When a spring loses tension, the door becomes heavier, the cables carry more load than they were designed for and they fatigue faster. When a spring snaps outright, the sudden shock frequently takes a cable with it.
So a cable that has broken on a door with original springs is a signal to check the spring set, not just to fit a new cable. Replacing the cable in isolation leaves the underlying overload in place, and the new cable will fail the same way.
Why forcing a skew door makes it worse
The instinct with a crooked door is to lift the low side by hand or to run the motor and hope it straightens out. Both make things considerably worse.
A door out of square puts its rollers into the track at an angle. Under power, that bends the track, gouges the channel and can pull rollers out of their sockets — turning a straightforward cable replacement into cable, track and roller work together, and sometimes a damaged section as well.
What the cables actually do
Each cable runs from an anchor on the bottom bracket of the door, up the side of the opening, to a grooved drum mounted on the torsion shaft. As the door closes, the cable winds onto its drum groove by groove; as it opens, it unwinds.
Because both cables share the load, they must wind at identical rates. That is what the grooves on the drums are for, and it is why drum position on the shaft is a measured setting rather than a rough alignment.

How it works
The garage door cable repair process in Kelvin
The same order on every job, whether it is a single household door or a run of doors in one complex.
- 01
Secure the door
The door is clamped in the tracks so it cannot move once the cables are released.
- 02
Release tension safely
Spring tension is wound off with winding bars before anything is disconnected.
- 03
Replace both cables
New cables of the correct diameter and length fitted, with bottom brackets checked and renewed if worn.
- 04
Reset the drums
Both drums cleaned, re-seated and wound so the two sides run at equal tension.
- 05
Re-tension and square
Springs re-tensioned to specification and the door squared in the opening.
- 06
Retest
Balance tested at three heights, travel and force settings reset, safety reverse retested.
Coverage
Getting a technician to Kelvin
Technicians are dispatched from Katherine Street in Sandton, which puts Kelvin inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
Openings in this part of the footprint are rarely square, which is normal for the age of the housing. Tracks get shimmed to the door's true vertical line rather than to the wall, and the bottom seal is picked to take up whatever the floor does across the width.
The same run covers Sandton, Sandown, Sandhurst and Parkmore, so a technician already working nearby can often be routed to Kelvin the same day. If your suburb is not listed, it is worth calling — the Sandton service area extends beyond the pages published so far.
Anything that leaves a property unsecured is dispatched ahead of standard bookings at any hour — see emergency garage door service.

What nearby customers say
Spring snapped on a Sunday evening and the car was locked in. Technician arrived within the hour and had the door working before nine.
Straight answer on repair versus replace, no upsell. New door fitted the following week and it is noticeably quieter.
Motor kept tripping after load shedding. Diagnosed the board, replaced it, tested it, done.
FAQ
Cable Repair in Kelvin: common questions
Do you repair garage door cables in Kelvin?
Yes. Snapped, frayed and slipped lift cables are replaced in pairs throughout Kelvin as part of our Sandton coverage, with the drums reset and the door squared afterwards. Technicians are dispatched from Katherine Street in Sandton, which puts Kelvin inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
My garage door in Kelvin is hanging crooked — should I still use it?
No. A crooked door has lost the support on one side, and every further cycle bends tracks and damages rollers. Use the manual release, leave the door down and book a Kelvin call-out — this is the fault where waiting genuinely costs more.
How quickly can you reach a broken cable in Kelvin?
Technicians are dispatched from Katherine Street in Sandton, which puts Kelvin inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings. A door left stuck open by a cable failure is treated as an emergency in Kelvin, because an open garage is a security problem rather than an inconvenience.
Why did my cable snap in Kelvin?
Usually fraying at the bottom bracket or drum where the cable bends sharply, corrosion at the lower end where water sits, or overload from springs that have lost tension. All three are checked on a Kelvin call-out.
Do both cables have to be replaced on my Kelvin door?
Yes. Both were fitted together and have carried the same load, so the survivor is close behind. A new cable also stretches at a different rate to an aged one, which puts the door out of square immediately. The extra cable costs very little in the context of the Kelvin call-out.
Will the springs need replacing too on my Kelvin door?
Sometimes, and it is checked on every visit. A cable that broke on a door with original springs is usually a symptom of springs that have lost tension and overloaded it. Doing both together in Kelvin means one release of tension and one labour charge rather than two.
Do you handle cable repairs near Kelvin?
Yes — Sandton, Sandown, Sandhurst and the wider Sandton area are covered by the same technicians carrying the same cable stock.
