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 Greymont
Garage door spring repair in Greymont
Greymont is an older residential suburb on the southern edge of the Randburg footprint, with compact stands and single garages. Aged tip-up doors with stretched extension springs and worn pivot hardware, plus significant corrosion on the older steel panels.
That is the context garage door spring repair in Greymont 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 Greymont. For the subject in full, see our garage door spring repair guide; for everything else we do here, see garage door services in Greymont.

Scope of work
What garage door spring repair in Greymont 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.
- Torsion springs on the shaft above the door, single or dual, for sectional doors
- Cones, winding bars, centre bearings and end bearing plates replaced where worn
- 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
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Greymont carries the same 12-month workmanship warranty as the rest of the footprint.
Real situations
What Greymont customers describe, and what it usually means
These are the calls we take most often from Greymont and the surrounding Randburg 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 Greymont
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.
Why both springs get replaced together
On a dual-spring door, both springs were fitted on the same day and have done exactly the same number of cycles. When one fails, the other is not healthy — it is simply a few weeks behind.
Fitting one new spring against one aged spring also unbalances the door, because the two no longer pull with the same force. The door lifts skew, one cable takes more load than the other, and the rollers grind against the track on the loaded side. Replacing the pair costs marginally more once and avoids a second call-out, a second labour charge and a door that never quite ran right in between.
How a torsion spring actually works
A torsion spring sits on a steel shaft above the door opening. As the door closes, the cables wind onto drums at each end of that shaft and twist the spring, storing energy. When you open the door, the spring unwinds and returns that energy, lifting the weight for you.
Balance is the whole point. On a correctly sprung door you can stop it at waist height with the motor disconnected and it will simply stay there — neither falling nor rising. That single test tells a technician more about a door's condition than any electronic diagnostic.

How it works
The garage door spring repair process in Greymont
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 Greymont
Greymont is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
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 Randburg, Northcliff, Blairgowrie and Parkhurst, so a technician already working nearby can often be routed to Greymont the same day. If your suburb is not listed, it is worth calling — the Randburg 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 Greymont: common questions
Do you replace broken garage door springs in Greymont?
Yes, and it is the most common job we do here. Torsion and extension springs for Greymont doors are carried on the van in the common sizes, so most spring replacements are finished on the first visit. Greymont is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
My spring broke and my car is locked in — can you come out to Greymont now?
Yes. A trapped vehicle is treated as an emergency in Greymont 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 Greymont?
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. Greymont is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
Why do garage door springs break so often in Greymont?
Fatigue and rust. Every open-and-close is one cycle and a standard spring is rated for about 10,000 of them. Greymont 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 Greymont 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 Greymont and keeps the door balanced.
Can you check the springs on other doors in my Greymont 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 Greymont visit at a lower cost per door.
Do you also handle spring repairs near Greymont?
Yes — Randburg, Northcliff, Blairgowrie and the rest of the Randburg area are on the same run, so a technician already carrying spring stock nearby can often reach you the same day.
