There was a bang like a gunshot from the garage and now the door will not lift

Spring Repair in Sandton CBD
The CBD is high-density: apartment blocks, mixed-use buildings and basement parking rather than individual driveways. Doors here are communal, which means one door absorbs the cycle count of dozens of households. Gearboxes, springs and roller bearings wear out on a timescale a domestic door never reaches, and safety beams take constant knocks from vehicles manoeuvring in tight bays.
That is the context garage door spring repair in Sandton CBD happens in. Doors in this node are often in shared basements where the same door serves several vehicles, pushing cycle counts far above a household door. Spring rating matters more than it does anywhere else in the footprint.
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 CBD. For the subject in full, see our garage door spring repair guide; for everything else we do here, see garage door services in Sandton CBD.
Own technicians, parts on the van, and a 12-month workmanship warranty in writing.
Scope of work
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.
A communal door carries the cycle count of every household behind it, which means domestic-rated springs and motors are simply the wrong specification even though the door looks ordinary.
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Sandton CBD carries the same 12-month workmanship warranty as the rest of the footprint.
Coverage
Technicians are dispatched from Sandton, which puts Sandton CBD inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
Work in the CBD is arranged through building management, and basement access and parking are confirmed before the technician arrives.
Where one receiver serves several households, nobody holds a complete list of the remotes coded to it. A periodic clear and re-code is the only way to know what is actually stored.
The same run covers Sandton, Sandown, Sandhurst and Parkmore, so a technician already working nearby can often be routed to Sandton CBD 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.
Real situations
These are the calls we take most often from Sandton CBD and the surrounding Sandton area.
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.
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.
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.
Uneven spring tension, or a cable that has slipped its drum. Stop using it. A skew door damages tracks and can jump its rollers.
Springs explained
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.
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.
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.

How it works
The same order on every job, whether it is a single household door or a run of doors in one complex.
Door weight, drum size, wire gauge and spring length are established before a part is chosen.
The door is clamped in position and the remaining tension is released with winding bars.
Both springs go on together, with cones, bearings and cables checked and renewed where worn.
The springs are wound to the calculated turn count, not by feel.
The door is balance-tested at three heights and the opener's force and travel limits reset.

FAQ
Yes, and it is the most common job we do here.

Yes. A trapped vehicle is treated as an emergency in Sandton CBD 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.
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 CBD inside the 20 minute window for emergency call-outs and usually same or next working day for standard bookings.
Cycle count. Doors in Sandton CBD are often opened many times a day, which uses up a standard spring's rated 10,000 cycles in a fraction of the years a low-use door would take. High-cycle springs are usually the better specification here.
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 CBD and keeps the door balanced.
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 CBD visit at a lower cost per door.
