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.

Spring Repair in Windsor
Garage door spring repair in Windsor
Windsor is a dense older residential area with compact stands and a high proportion of original housing stock. Original tip-up doors and considerable corrosion at the bottom edge. Replacement is frequently the honest recommendation here.
That is the context garage door spring repair in Windsor 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 Windsor. For the subject in full, see our garage door spring repair guide; for everything else we do here, see garage door services in Windsor.

Scope of work
What garage door spring repair in Windsor 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.
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.
- Cones, winding bars, centre bearings and end bearing plates replaced where worn
- lift cables inspected at the same time, since a spring failure often damages them
- Door re-balanced and the motor's force settings recalibrated after fitting
- Torsion springs on the shaft above the door, single or dual, for sectional doors
- Extension springs running alongside the horizontal tracks, typical of tip-up and older doors
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Windsor carries the same 12-month workmanship warranty as the rest of the footprint.
Real situations
What Windsor customers describe, and what it usually means
These are the calls we take most often from Windsor and the surrounding Randburg area.
There was a bang like a gunshot from the garage and now the door will not lift
A torsion spring has broken. That noise is the coil releasing its stored tension. Do not operate the door. Book a spring replacement — this is the textbook case.
The door is very hard to lift by hand with the motor disconnected
Under-sprung. Either a spring has failed, or the springs fitted were never rated for this door's weight. Have the door weighed and the spring specification checked, not just replaced like for like.
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.
Springs explained
What garage door springs do and why they fail in Windsor
Torsion springs versus extension springs
Torsion springs are the modern standard on sectional doors: mounted centrally, wound under controlled tension, and safer in failure because the spring stays captive on its shaft.
Extension springs stretch along the horizontal tracks and are still found on tip-up doors and older installations. They do the same job less elegantly, and when one breaks it can travel — which is why safety containment cables through the centre of an extension spring are not a nice-to-have.
Both types are fitted and replaced. What we will not do is fit a torsion conversion to a door that does not have the headroom for it, or leave an extension spring without its containment cable.
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.
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

How it works
The garage door spring repair process in Windsor
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 Windsor
Windsor 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.
The doors here have usually had several owners and several repairers, and the history matters. A force setting that was turned up years ago to mask a dragging roller is still turned up, and the door has been pushing through the problem ever since.
The same run covers Randburg, Northcliff, Blairgowrie and Parkhurst, so a technician already working nearby can often be routed to Windsor 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 Windsor: common questions
Do you replace broken garage door springs in Windsor?
Yes, and it is the most common job we do here. Torsion and extension springs for Windsor doors are carried on the van in the common sizes, so most spring replacements are finished on the first visit. Windsor 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 Windsor now?
Yes. A trapped vehicle is treated as an emergency in Windsor 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 Windsor?
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. Windsor 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 Windsor?
Fatigue and rust. Every open-and-close is one cycle and a standard spring is rated for about 10,000 of them. Windsor 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 Windsor 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 Windsor and keeps the door balanced.
Can you check the springs on other doors in my Windsor 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 Windsor visit at a lower cost per door.
Do you also handle spring repairs near Windsor?
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.
