I replaced one spring last year and now the other has gone
The classic consequence of replacing a broken spring singly rather than as a pair. Replace as a matched set this time so the cycle life resets on both sides.

Spring Repair in Sandton
Garage door spring repair in Sandton
Sandton is two building eras stacked on top of each other: the tower blocks and apartment nodes around the CBD, and the older freestanding homes on large stands that surround them in Sandhurst, Atholl and Hyde Park. That split shows up in the work. The apartment and cluster side generates high-cycle wear — springs, rollers and motor gearboxes. The older freestanding side generates weight problems: heavy timber and steel doors, often retro-automated, on springs that were never quite specified for them.
That is the context garage door spring repair in Sandton happens in. Older properties in this area often still run extension springs on tip-up doors, or early torsion sets on doors that have been retro-automated. Both need the spring specification checked against the door's real weight rather than replaced like-for-like, because the original sizing frequently was not right to begin with.
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 Sandton. For the subject in full, see our garage door spring repair guide; for the rest of what we do in the area, see garage door services in Sandton.

Scope of work
What garage door spring repair in Sandton covers
Spring work is measured before it is quoted. The correct spring is a function of the door's weight, its height and the drum size it winds onto — get any of those wrong and the door will be over- or under-sprung, which shortens the life of the spring, the cables and the motor together.
Tip-up doors use extension springs rather than a torsion bar. They are cheaper to replace but need their safety containment cables intact — without them, a snapping extension spring becomes a projectile inside the garage.
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.
- Extension springs running alongside the horizontal tracks, typical of tip-up and older doors
- lift cables inspected at the same time, since a spring failure often damages them
- Springs supplied in matched pairs, so both sides share the load and the cycle life
- Door re-balanced and the motor's force settings recalibrated after fitting
- Cycle-rated springs matched to how often the door is actually used, not the cheapest available
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Sandton carries the same 12-month workmanship warranty as the rest of the footprint.
Real situations
What Sandton customers describe, and what it usually means
These are the calls we take most often from Sandton and the surrounding Sandton area.
The door lifts skew, with one side leading the other
Uneven spring tension, or a cable that has slipped its drum. Stop using it. A skew door damages tracks and can jump its rollers.
The door crashes down the last half-metre instead of settling gently
Spring tension has dropped. The springs are no longer holding the door's weight. Retension or replacement, depending on age and cycle count — and it is a safety issue, not a comfort one.
The motor lifts the door 10cm, then stops and reverses
The opener is hitting its force limit because the door is now far heavier than the spring assistance it expects. Turning the force setting up will destroy the motor. The spring is the fix.
Springs explained
What garage door springs do and why they fail in Sandton
What happens when a spring breaks
The door becomes its raw weight — commonly 80 to 140kg on a double sectional. An automated opener will strain, trip its overload and stop, or lift the door 100mm and give up. If the opener is strong enough to keep trying, it damages itself, the trolley, and eventually the top section of the door.
Manually, the door is now genuinely dangerous. A door part-way open on a broken spring is held by nothing but friction and the second spring, if there is one. It can come down fast and it does not stop for whatever is underneath it.
The right response is to stop. Leave the door closed if it is closed. If it is open, do not walk under it, do not put a car under it, and call for an emergency garage door call-out.
Signs a spring is about to go
The failure is instant but the warning is not. A spring on its way out shows up first in how the door behaves, and it is worth acting at that stage rather than the next one.
- The door feels heavier by hand than it used to, or will not stay at waist height
- It opens more slowly, or the motor sounds like it is straining on the way up
- You can see a gap in the coil, or the spring has separated into two visible sections
- The coils look rusty, stretched, or unevenly spaced along the length
- The door judders or jerks upwards instead of moving in one smooth run
- It slams the last stretch on the way down instead of settling
Why garage door springs break
Springs fail from fatigue, not from abuse. Every open-and-close is one cycle, and a standard spring is rated at roughly 10,000 of them. A household opening the door four times a day reaches that in about seven years; one opening it ten times a day gets there in under three.
Three things accelerate it. Rust, which pits the steel and creates a stress point — the reason a light oiling once a year genuinely extends spring life. Incorrect sizing, where a spring that was never right for the door weight has been fighting from day one. And imbalance, where a worn partner spring, dragging rollers or a bent track make the surviving spring work harder than it was rated to.

How it works
The garage door spring repair process in Sandton
The same order on every job, whether it is a single household door or a run of doors in one complex.
- 01
Weigh and measure
Door weight, drum size, wire gauge and spring length are established before a part is chosen.
- 02
Secure and release
The door is clamped in position and the remaining tension is released with winding bars.
- 03
Replace as a pair
Both springs go on together, with cones, bearings and cables checked and renewed where worn.
- 04
Wind to specification
The springs are wound to the calculated turn count, not by feel.
- 05
Balance and recalibrate
The door is balance-tested at three heights and the opener's force and travel limits reset.
Coverage
Getting a technician to Sandton
Technicians are dispatched from Sandton, which puts Sandton inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
Technicians are dispatched from inside Sandton itself, which is why it sits at the fast end of our response times rather than being routed in from elsewhere.
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 Morningside, Rivonia, Bryanston and Rosebank, so a technician already working nearby can often be routed to Sandton 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.

FAQ
Spring Repair in Sandton: common questions
Do you replace broken garage door springs in Sandton?
Yes, and it is the most common job we do here. Torsion and extension springs for Sandton doors are carried on the van in the common sizes, so most spring replacements are finished on the first visit. Technicians are dispatched from Sandton, which puts Sandton inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
My spring broke and my car is locked in — can you come out to Sandton now?
Yes. A trapped vehicle is treated as an emergency in Sandton at any hour, including weekends and public holidays. Do not try to force the door in the meantime — on a broken spring it is unsupported and can drop.
How long does a spring replacement take in Sandton?
Typically 60 to 90 minutes on site once the technician arrives, including weighing the door, fitting the matched pair, re-balancing and resetting the motor force. Technicians are dispatched from Sandton, which puts Sandton inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
Why do garage door springs break so often in Sandton?
Fatigue and rust. Every open-and-close is one cycle and a standard spring is rated for about 10,000 of them. Sandton doors that are used several times a day get there far sooner than the seven years the rating implies.
Should both springs be replaced on my Sandton door?
On a dual-spring door, yes. Both were fitted together and have the same cycle history, so the surviving spring is weeks or months from failing. Replacing the pair once avoids a second call-out in Sandton and keeps the door balanced.
Can you check the springs on other doors in my Sandton complex or street?
Yes, and it is worth asking. Doors fitted at the same time in the same development reach the end of their spring life at the same time, so we regularly check and replace several doors in one Sandton visit at a lower cost per door.
Do you also handle spring repairs near Sandton?
Yes — Morningside, Rivonia, Bryanston and the rest of the Sandton area are on the same run, so a technician already carrying spring stock nearby can often reach you the same day.
