Garage Door Repairs Adelaide
When a garage door stops working, it is usually one part that has let go — a spring, a cable, a worn roller, or the opener — rather than the whole door. We repair roller, sectional, tilt and automatic doors across the Adelaide CBD and the inner suburbs, work out the actual cause on site, and explain what needs replacing before any work starts.

Common garage door faults we repair in Adelaide
Adelaide homes have a real mix of doors — original tilt doors on older houses, sectional doors on newer builds, and roller doors on garages and sheds everywhere in between. Different doors, but the same handful of faults come up again and again.
Door won't open or close
The opener hums or clicks but the door doesn't move. Usually a broken spring or cable, or the opener's drive gear rather than the motor itself.
Door is too heavy to lift
A door that suddenly feels like dead weight has lost its spring tension. Lifting it by hand risks injury and strains the opener.
Opens then reverses
Something is blocking the path, the safety beam is misaligned or dirty, the travel limits have drifted, or the door has become stiff to move.
Off the tracks or jammed
A door that has jumped a track or bent a roller needs to be freed carefully before anything is run again, so nothing is damaged further.
Bent or damaged panels
Sections, slats and bottom rails take the hit when a car nudges the door or the door comes down on an obstruction.
Loud, grinding or shuddering
Worn rollers, dry or damaged bearings, loose hinges and a door that is out of balance all show up as noise before they fail.
Remote or wall button dead
Flat remote battery, lost coding, a keypad fault or a problem at the opener's board — we test the whole chain, not just the remote.
Won't stay closed
A door that reopens or drifts down unevenly may be out of balance, or the opener's force and limit settings need re-checking.
Roller, sectional, tilt, automatic and commercial doors
Each type of door fails in its own way. Knowing the door you have is the first step to quoting the repair properly, so here is what we look at on each.
Roller doors and shutters
A single curtain of slats that rolls up above the opening. Repairs usually involve the curtain coming out of its guides, bent guides, worn drum bearings or wheels, a lock that no longer engages, spring failure, or a roller door motor that only works one way.
- Curtain re-set into the guides
- Guides, brackets, locks and bottom rails
- Drum bearings, wheels and roller springs
- Manual roller doors converted to automatic
Sectional garage doors
Panels hinged together that travel up and back along ceiling tracks, so they suit garages with limited headroom in front of the opening. The faults we see most are torsion springs, cables off the drums, worn rollers and hinges, panel damage and a door that has come off its track.
- Torsion spring replacement and re-tensioning
- Cable, drum and roller repairs
- Hinge, track and panel straightening
- Opener set-up, limits and safety reverse
Tilt and canopy doors
One rigid panel that tilts back as the door opens — still common on older Adelaide homes. Tilt doors lean heavily on their springs and pivot arms, and many are well suited to being automated while keeping the original door.
- Spring and pivot arm repairs
- Panel and frame damage
- Jamming and binding as the door tilts
- Adding an opener to a sound existing door
Automatic and motorised doors
Most automatic door faults are either mechanical — the door has become too heavy or stiff for the opener to move — or electronic, in the opener itself. Working out which side of the system is at fault is the first thing we check.
- Opener runs but the door doesn't move
- Safety beam and auto-reverse faults
- Travel limits and force settings
- Remotes, keypads and wall controls
Commercial and industrial doors
Businesses can't afford a door that is stuck open or jammed shut. We service and install all types of doors, including large commercial garage doors, and repairs are aimed at getting the door back into service with as little disruption as possible.
- Large roller shutters and commercial sectionals
- High-use doors and repeat faults
- Motor, gearbox and drive repairs
- Straightening, alignment and re-tensioning
Spring replacement, sizes and heavy-duty springs
The springs carry the weight of the door. That is why a garage door can weigh well over 100 kilograms and still be lifted with one hand — and why a broken spring makes the same door almost impossible to move. A spring is never a generic part you can swap for "the same size"; it is specified against the door it lifts.
Torsion springs
Mounted on a shaft above the door and wound tight, these do the lifting work. Most doors run a pair — a left-hand and a right-hand wound spring. When one breaks you'll usually hear it, and the door suddenly becomes far too heavy to lift.
Extension springs
Fitted along the horizontal tracks and stretched as the door closes, these are common on older tilt and sectional doors. They fail by stretching or snapping, which is why a safety cable should always run through the spring.
How a spring size is worked out
Spring sizes are read and specified by a handful of measurements. We measure the door and the failed spring rather than guessing from the make or model:
The thickness of the spring wire — a heavier gauge lifts more door weight.
The bore of the spring, which has to match the shaft and drum it fits.
Set by the door height and the amount of lift the spring needs to give.
Torsion springs are wound left-hand and right-hand, and are fitted as a matched pair.
The spring calculation starts here — a door's weight, not its width, decides what fits.
How many open-and-close cycles the spring is built for before it should be replaced.
Standard springs are rated for a set number of open-and-close cycles. On a busy household — or a door that runs many times a day, such as a business, a shared driveway or a multi-door complex — that allowance is used up quickly, and the springs end up being replaced far more often than they should.
A heavy-duty, high-cycle spring is built from a heavier wire and designed to last far more cycles before it needs attention. It is specified to the same door weight and dimensions as a standard spring, so it fits the door you already have — the difference is how long it keeps working. We will tell you when heavy-duty makes sense for your door and when the standard rating is all you need.
Garage door cable repairs
The cables run from the bottom corners of the door to the drums on the spring shaft, or along the tracks on an extension-spring door. Working together, they keep the door square and lift it evenly on both sides. If one cable fails, the door is being carried on one side only — which is why it hangs crooked and why it should not be used.
Signs of a cable problem
- One side of the door sits lower than the other, or the door hangs crooked
- A cable has come off its drum or is sitting loose along the track
- The cable looks frayed, kinked or has strands broken away
- The door shudders, binds or grinds as it travels up and down
- The door has come off its tracks altogether
- A sharp bang or snap, followed by a door that will not move normally
Why cables fail
Cables are under constant tension and carry the pull of the door thousands of times. They corrode, fatigue and fray over the years, and they are easily kinked by a door that has jumped a track, come down on an obstruction, or been forced while something else was already broken.
That is why a cable is rarely the whole story. A cable often goes because a spring has broken, a drum has come loose or the door has come off its tracks — and replacing the cable alone leaves the real cause in place. We inspect the springs, drums, rollers and tracks at the same time, re-tension both sides, and check the door sits level with the opener's travel limits set correctly.
Cables and springs are under high tension. Never cut or remove one, and never run a door with a loose cable, even "just to get the car out".
Garage door motor repairs and opener types
An opener is only ever as good as the door it is lifting. If your door has become heavy, stiff or out of balance, a perfectly healthy motor will struggle, strain and eventually fail — so we always check the door first, then the motor.
Chain drive openers
A metal chain pulls the door along its rail. Strong and well suited to heavier sectional doors, at the cost of a little more noise as the door runs.
Belt drive openers
The same idea with a reinforced belt instead of a chain. Quieter, which makes them a common choice where a garage shares a wall with a bedroom or living area.
Screw drive openers
A threaded steel rod moves the trolley, so there are few moving parts and less to maintain. They suit a well-balanced door and are popular where the garage is rarely used.
Wall-mounted (jackshaft) openers
Mounted on the wall beside the door and driving the shaft directly, leaving the ceiling clear. Suited to roller doors and garages with low headroom or ceiling space used for storage.
Roller door and shutter motors
Roller doors use a tube motor inside the barrel or an overhead unit that raises the curtain on a chain or strap — a different set-up to a sectional door opener.
Motor faults we repair
- The motor runs but the door doesn't move. Almost always mechanical — a broken spring or cable, a stripped gear, or a door that has jammed. The opener is doing its job; the door can't answer it.
- The door reverses or stops part-way. Obstruction in the path, a misaligned or dusty safety beam, travel limits that have drifted, or a door the opener can no longer lift.
- Remotes and keypads stop working. Flat batteries, lost coding, interference from nearby equipment, or a fault on the opener's board.
- The opener is slow, noisy or unreliable. A tired motor, a dry or worn drive, or an opener that was only ever matched to a lighter door.
Repairing is often the sensible answer — remotes, keypads, safety beams, drive parts, limits and settings can all be sorted without a new opener. Replacement makes more sense when the motor itself is worn out, when parts are no longer available, or when the door has changed and the opener no longer suits it. We'll tell you which it is and why.
We also fit Merlin openers to new and existing doors, so a door that is still in good condition can be automated — after fitting we code your remotes, set the travel limits, adjust the safety reverse and walk you through how the opener works.
After a motor repair or install
- Automatic safety reverse and photo beams
- Travel limits and force settings to suit the door
- Handheld remotes and wireless keypads
- Wall-mounted buttons and internal controls
- Quiet belt drives for garages near living areas
- Battery backup and smart control options
The repair process, start to finish
Tell us what's happening
Call us or send the quote form. It helps to know the door type, whether the door is stuck open or closed, and what you saw or heard when it stopped working.
Book a visit
We arrange a time that suits you, for the Adelaide CBD and the inner suburbs within roughly 7–10 km of the city.
On-site diagnosis
We test the door, opener, springs, cables, rollers and tracks to find the actual cause — rather than adjusting the door and hoping the symptom goes away.
Quote before work starts
You're told what has failed and what the repair involves, and nothing proceeds until you're happy with it.
Repair and test
The repair is completed, then the door's balance, the opener's travel limits and the safety reverse are all tested before we leave.
Aftercare
We explain what to keep an eye on, how to keep the door running quietly, and when it should be serviced again.
Door stuck open, or won't open at all?
Don't force it — a jammed door can bend panels, cables and tracks. Give us a call and we'll book a technician to the fault.
