The short answer
Almost every garage door fault traces back to one of six things: a spring, a cable, a track, a roller, the motor, or the safety beams that tell the motor what to do. A technician who knows the sequence to test them in will usually name the cause within ten minutes of arriving, and the majority of doors are back in service on the same visit.
That is what this page is about — what actually breaks on a garage door, how the fault is identified, when a repair is the right call and when it is money spent on a door that should be replaced. If your door is currently stuck open and the property is standing unsecured, that is an emergency garage door service rather than a booking.

Scope of work
A repair call-out is a diagnosis first and a repair second. The technician tests the door manually with the motor disconnected, checks the balance at three positions, inspects both lift cables and their drums, sights the tracks for distortion and only then looks at the electronics. Skipping that order is how a perfectly good motor gets replaced on a door whose real problem was a stretched spring.
The work itself covers the mechanical assembly and the automation together, because on an automated door the two are inseparable — a heavy, badly balanced door will burn out a motor, and a motor set to too much force will destroy a door.
Where a fault turns out to be beyond economic repair, you get the comparison rather than a sales pitch: what the repair costs, what a garage door replacement costs, and how long the repaired door is realistically likely to last.
Common faults
A door that refuses to open is usually a broken torsion spring. The motor will strain, hum, or move a few centimetres and stop, because without spring assistance it is being asked to lift the door's full weight — often more than 100kg on a double sectional. Look at the spring above the door: a broken one has a visible gap, like a spiral cut in half.
The second most common cause is a snapped or derailed lift cable, which leaves one side of the door lower than the other. The third is an opener fault — a stripped drive gear or a failed board — where the motor runs but nothing moves.
Do not keep pressing the remote. Every attempt after a spring or cable failure drags the door further out of square and turns a straightforward spring repair into track and panel damage as well.
A door that opens but refuses to close is almost always the safety beams. The two infrared sensors mounted low on either side of the opening must see each other; a spider web, a bag leaning against one, a knocked bracket or a lens covered in dust breaks the beam and the opener refuses to close as designed. Most units flash an error code on the head unit while this is happening.
If the beams are clear and aligned, the next suspects are the down-travel limit setting and the close-force setting on the control board. A door that closes fully and then immediately reverses is being told it has hit an obstruction — usually because the limit is set slightly too low and the door is pressing into the floor.
Springs are the single most common failure point on any garage door because they do the actual lifting. A torsion spring is rated in cycles — typically 10,000 for a standard spring, which is roughly seven years at four cycles a day, and considerably less on a household that runs the door eight or ten times daily.
When one breaks, the door becomes dangerously heavy and unbalanced. Springs are replaced in matched pairs for a reason: both have the same cycle history, and fitting one new spring against one worn spring leaves the door pulling to one side and the survivor failing within months. Full detail is on the garage door spring repair page.
The lift cables run from the bottom bracket of the door up to a grooved drum on the spring shaft. When a cable frays, jumps its groove or snaps, that corner of the door drops and the door sits visibly skew in the opening.
A skew door binds in the tracks, and forcing it under motor power bends track sections and can pull the door off its rollers entirely. Cables are always replaced as a pair and the drums reset so both sides wind evenly — see garage door cable repair.
Tracks take the punishment when a vehicle nudges the door, when a roller seizes and gouges the channel, or when a bracket works loose over years of vibration. Once a track is out of true, the door grinds at one point in its travel, sticks halfway, or jumps a roller out of the channel altogether.
Minor distortion can be straightened in place. Anything creased, split at a joint or bent at the radius needs the section replaced and the whole run re-shimmed — the detail is on the garage door track repair page.
Opener faults split into mechanical and electronic. Mechanically, a stripped nylon drive gear or a disengaged trolley makes the motor run happily while the door stays put. Electronically, a failed capacitor gives you a motor that hums but will not start, and a damaged control board gives intermittent behaviour that changes day to day.
In this part of Johannesburg, load shedding adds a third category. Repeated hard power cuts kill backup batteries early, corrupt stored travel limits and, over time, take out boards. If your door stopped behaving after a bout of outages, start at the battery and the board — garage door opener repair covers the full test sequence.
Noise is diagnostic. A rhythmic squeal that speeds up with the door is dry roller bearings. A metallic grinding is a roller running on a damaged track or a bearing that has collapsed. A deep bang partway through travel is usually a hinge or a section joint taking load it should not be taking. A rattling that changes when the door is nearly closed points at loose track brackets.
Shuddering, where the door climbs in a series of jerks, is a balance problem: the springs no longer match the door weight and the motor is dragging it. Left alone it will end in a burnt motor or a snapped spring, and it is exactly the fault an annual garage door maintenance visit is designed to catch.
Real situations
These are the calls we take most often. If one of them sounds like your door, it is worth reading what it means before you operate it again — and if the property is standing open, treat it as emergency garage door service.
Usually a spring that failed mid-travel, or a roller that has come out of the track and jammed the door against the frame. Do not use the remote again. Pull the manual release only if the door is supported, and book a repair.
A stripped drive gear, a disengaged trolley, or a chain or belt that has jumped its sprocket. A same-day fix in most cases — see opener repair.
A lift cable has slipped its drum or snapped, so one corner is no longer supported. Stop operating it immediately. A skew door damages tracks quickly and can come off entirely.
The opener thinks it has struck an obstruction: blocked safety beams, a close-limit set too low, or a raised floor edge. Check the beam lenses first, then have the travel limits reset properly.
That bang is the sound of a torsion spring breaking. It is the most common of all. The door is now unbalanced and heavy. Leave it where it is and book spring replacement.
Dry or collapsed roller bearings, a damaged track, or springs that no longer balance the door. Catch it now and it is a service. Ignore it and it becomes a motor replacement.
Fixed quote before work starts, and the repair-versus-replace comparison where it matters.
Diagnosis
The test sequence matters more than any single check, because several faults produce the same symptom. Every repair call-out follows the same order.
The result is a written fixed quote before anything is dismantled, including the honest version — if the door is at the end of its life, you will be told that rather than sold a repair that buys six months.
How it works
Every job follows the same order, whether it is a household door in Sandton or a high-cycle door in a complex.
Call or WhatsApp what the door is doing — a short video of the fault is worth ten minutes of description.
The motor comes off and the door is worked by hand before any part is blamed.
You approve a price, with the repair-versus-replace comparison where it is relevant.
Common springs, cables, rollers and hinges travel with the technician, so most jobs close on the first visit.
Balance, travel limits, force settings and auto-reverse are all retested before sign-off.
Making the call
Most doors are worth repairing. A door with straight panels, a square frame and sound tracks can absorb several spring and cable replacements over its life and still be the cheaper option by a wide margin.
Replacement starts to make sense in four situations: the panels are rusted through at the bottom edge; the door has taken an impact that has twisted the sections; repairs are now stacking up two or three a year on a door past fifteen; or the repair quote comes to more than roughly half the price of a new door of the same specification.
There is also a middle path that gets overlooked. On a sectional door, a single damaged panel can often be replaced without touching the rest, and on a sound door with a dead motor you keep the door and fit a new garage door motor only. Both are covered under garage door replacement advice, and both are quoted alongside the full-replacement figure so you can compare like with like.

Safety
A garage door is one of the few things in a house that stores enough energy to seriously injure someone. A torsion spring on a double door holds the equivalent of the door's full weight in wound tension, and releasing it without winding bars and the correct technique is how people lose fingers.
Cables are under the same load. A cable released at the drum whips, and a door supported by one cable can drop through its travel without warning. Neither job is difficult for someone equipped for it and neither is safe for someone who is not.
The other half of the argument is diagnostic rather than physical. Replacing a part that is not the cause is expensive and common — the classic being a new opener fitted to a door whose springs were the actual problem, which then destroys the new opener too.
Prevention
Garage doors rarely fail without notice. The failure is sudden; the deterioration that caused it usually announced itself for weeks.
Any of those is a cheap service call now and an expensive breakdown later. An annual garage door service exists precisely to catch them, and doors used several times a day benefit from a six-month interval.
Garage Door Repair rarely happens in isolation. These are the services most often needed alongside it: garage door spring repair, garage door cable repair and garage door track repair.
Garage Door Repair is available across the whole footprint. These are the areas it is requested from most: Sandton, Fourways, Bryanston and Midrand. Every published suburb has its own page listing what we see on doors in that area.
Reviews
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
Most repairs are finished in one to two hours on site. Spring and cable replacements are usually under 90 minutes, track work runs longer, and jobs that need a part ordered in are made safe on the first visit and completed on the second.
Standard bookings are usually attended the same or next working day, and emergency call-outs across Sandton average 20 minutes. Doors left standing open are prioritised over doors that are simply not working.
A call-out and diagnostic fee applies, and it is credited against the repair if you approve the quote on the day. You are told the figure on the phone before a technician is dispatched.
Disconnect the motor with the manual release and lift the door by hand. If it is heavy, drops, or will not stay at waist height, the problem is mechanical — springs or cables. If it lifts easily by hand but will not move under power, the fault is in the opener.
No, in three cases specifically: a broken spring, a snapped or slipped cable, and a door sitting visibly skew in the opening. In all three the door is unsupported and can drop. Use the manual release, leave the door down and book a repair.
Yes. Sectional, tip-up and roller doors in steel, aluminium, timber and glass fibre, with Centurion, Digidoor, Chamberlain, Gliderol and ET automation. Parts for the common local brands are carried on the van.
