Whether you have a standard two-panel patio door or a large four-panel aluminium sliding door, the first step is finding out what is actually causing the problem.
From R850
Most sliding doors don’t suddenly stop working without warning. They usually become a little heavier, noisier or more difficult to close over time.
If you recognise one of the problems below, it may be time to have the door checked.
A sliding door that once moved easily may gradually become heavy.
Worn rollers are a common cause, but they are not the only possibility. The track may be damaged, the panel may have dropped out of alignment, or the rollers may simply need adjustment.
Instead of assuming which component has failed, we check the rollers, track and panel alignment together.
If the door barely moves, avoid repeatedly forcing it.
A seized or collapsed roller can cause the panel to drag directly against the track. Continuing to push a heavy door may damage the track, handle or other components and turn a relatively straightforward repair into a bigger one.
Can you hear metal scraping when you move the door?
The sliding panel may have dropped too low because of worn rollers, incorrect roller adjustment or another alignment problem.
The cause should be corrected rather than simply forcing the panel along the track.
A panel that repeatedly jumps, tilts or comes off its normal running position may have problems with its rollers, guides, track or alignment.
Simply putting the door back into position may not solve the underlying problem.
Sometimes the sliding action is fine but the door will no longer lock.
The lock itself may be damaged, but the problem can also be caused by the door dropping slightly and leaving the lock and keep out of alignment.
This is why the door alignment should be checked before replacing working hardware unnecessarily.
Excessive movement or rattling can be associated with worn wool pile, damaged seals, incorrect panel adjustment or worn components.
The correct repair depends on where the movement is coming from.
Broken glass does not automatically mean that the complete aluminium sliding door must be replaced.
Where the aluminium panel and frame remain serviceable, the damaged pane can often be removed and replaced with correctly specified glass.
A sliding door is a complete system. The rollers, track, aluminium panel, handle, lock, seals and glass all need to work together.
That is why we focus on diagnosing the cause rather than simply replacing the first part that looks worn.
The rollers underneath the moving panel carry the weight of the door and allow it to travel along the track.
As rollers wear, seize or collapse, you may notice:
Where worn rollers are responsible, they can be removed and replaced with suitable components before the panel is adjusted and tested.

New rollers cannot perform properly on a badly damaged running surface.
Tracks can become worn, bent or damaged, particularly when a door has been operated for a long time with failed rollers.
Common signs include a door that catches in the same place, grinding noises, visible track damage or a new roller that still doesn’t run smoothly.
We inspect the track and rollers together to determine what needs attention.

Not every difficult sliding door needs new parts.
Sometimes the panel has moved out of its correct position and requires adjustment.
Correct alignment can affect:
Adjustment may also be completed after roller or track work to ensure the repaired door operates correctly.
A patio door that closes but cannot lock properly is both inconvenient and a security concern.
We assess problems involving sliding door locks, handles, latches, keeps and alignment.
We also check whether the locking problem is being caused by the door itself. A dropped sliding panel can make a perfectly serviceable lock appear faulty because the lock and keep no longer line up correctly.

Cracked or shattered sliding door glass should be dealt with carefully, particularly on large patio doors.
Where the aluminium frame and sliding panel remain in usable condition, we can assess the damaged glazing and replace the glass without unnecessarily replacing the complete door.
The correct glass specification depends on the application, size and existing door.

A door may still slide but feel loose, rattle in the frame or allow noticeable draughts through.
Worn wool pile and seals can contribute to these problems.
We can assess the condition of the seals together with the overall panel alignment to determine what requires replacement or adjustment.
A heavy sliding door doesn’t automatically mean “replace the rollers”.
Different faults can produce very similar symptoms.
| What you notice | Possible cause |
| Door has become very heavy | Worn or damaged rollers |
| Door moves unevenly | Rollers, track or alignment |
| Panel scrapes at the bottom | Dropped panel or roller problem |
| Grinding while opening | Roller or track damage |
| Door catches at one particular point | Damaged track or alignment |
| Door repeatedly comes off track | Rollers, guides or alignment |
| Door closes but doesn’t lock | Lock, keep or panel alignment |
| Door rattles when closed | Adjustment, wool pile or seals |
| Handle moves but lock doesn’t engage | Lock mechanism or alignment |
The important part is diagnosis.
Replacing rollers won’t fix a badly damaged track, and replacing a lock won’t solve a door that has dropped so far that the lock can no longer meet the keep.
We look at the sliding system as a whole before recommending the repair.
The cost depends on what is actually wrong with the door.
A simple adjustment is very different from repairing a damaged track, replacing hardware or fitting new glass.
Typical Sigmadoors repair prices include:
| Aluminium Sliding Door Repair | Price From |
| Sliding door adjustment / alignment | R850 |

A difficult sliding door doesn’t automatically need to go into a skip.
Many aluminium doors have perfectly usable frames and glass but are difficult to operate because one or two serviceable components have worn out.
Repair may be practical where:
Replacement may make more sense where the aluminium frame or panel is severely distorted, major parts of the system are extensively damaged, suitable components cannot reasonably be sourced, or the cost of restoring the old system is no longer practical.
Where replacement makes more sense, Sigmadoors also manufactures and supplies aluminium sliding doors.

Not every sliding door is built the same way.
Understanding the configuration helps when identifying the moving panels, locks, interlocks, rollers and other components that need attention.
A typical OX sliding door has two main sections — one fixed panel and one sliding panel.
This is one of the most common patio-door arrangements in South African homes.
An OXXO configuration has four panels, with two outer fixed panels and two centre sliding panels.
The centre panels meet in the middle and slide away from the centre when opened.
Correct centre-stile alignment is particularly important for smooth closing and locking.
Larger glazed panels place more load on the rollers and tracks.
If a heavy door starts becoming difficult to operate, repeatedly forcing it can increase wear on the running components.
Correct replacement components and accurate adjustment become particularly important on larger systems.
Premium and heavy-duty aluminium sliding systems generally use more substantial profiles and larger glazed panels than basic patio doors.
Their weight and hardware requirements need to be considered when diagnosing roller, track and alignment problems.
We’ve kept the process simple.
Heavy? Stuck? Scraping? Not locking? Broken glass?
Show the complete door as well as the damaged area.
The likely roller, track, lock, alignment, glass or hardware issue can then be identified.
You know what needs attention before the work proceeds.
Required adjustments, repairs or replacement components are completed.
The sliding action, closing, alignment and locking are checked where applicable.

Aluminium sliding doors are what we work with.
Sigmadoors doesn’t only repair doors — we work with aluminium window and door systems, which gives us an understanding of how the frame, sliding panel, rollers, tracks, locks, handles, seals and glazing work together.
Our repair services cover:
Our approach is simple: identify the problem first, then repair what actually needs repairing.
Minor adjustments start from around R850, while roller replacement starts from approximately R850. More involved repairs involving tracks, locks, handles or glass cost more. The final price depends on the door and the work required.
Worn rollers are a common cause, but the problem could also involve the track, panel alignment or a combination of components. The door should be assessed before deciding which parts need replacement.
Yes. Where worn or damaged rollers are causing the problem and suitable replacements are available, the rollers can usually be replaced and the door readjusted.
Many track problems can be repaired, depending on the type and extent of the damage. The rollers should also be inspected because damaged rollers and damaged tracks often affect one another.
Possible causes include worn rollers, damaged guides, track problems or incorrect panel alignment. Continually putting the panel back without correcting the cause may allow the problem to return.
Yes, depending on the fault. The problem may involve the lock, handle, keep or alignment between the sliding panels. We check the alignment as well as the locking hardware.
Yes. Scraping often indicates a roller or alignment problem. It is worth addressing before continued use damages the track or aluminium panel.
In many cases, yes. If the aluminium panel remains serviceable, the damaged glass can often be replaced without replacing the complete sliding door.
Age alone doesn’t determine whether replacement is necessary. If the frame and panels remain in reasonable condition, replacing worn rollers, hardware, seals or glass may restore the door. Severely damaged or distorted systems may be better candidates for replacement.
Send a clear photo of the entire door, close-up photos of the problem, approximate dimensions, your Sandton suburb and a short description of what happens when you try to open, close or lock the door.
