A sliding door is a complete operating system. The aluminium frame, sliding sash, rollers, track, locks, handles, seals and glass all need to work together.
Finding the actual cause of the problem is therefore an important part of a successful repair.
Rollers carry the weight of the moving aluminium door panel and allow it to travel along the bottom track.
As rollers wear, the door may become increasingly difficult to move. You may notice that it feels heavy, moves unevenly, makes a grinding sound or needs to be lifted slightly before it will slide.
Simply forcing the door does not solve the problem and may eventually damage the track or other components.
Where appropriate, we inspect the existing rollers, roller adjustment and track condition before recommending sliding door roller replacement.
The track provides the running surface for the rollers. If it becomes damaged, badly worn, dented or distorted, even good rollers may struggle to operate correctly.
Common signs include:
A proper sliding door track repair should consider both the condition of the track and the rollers running on it.
An aluminium sliding door can sometimes move but still be incorrectly aligned.
You may notice uneven gaps around the frame, scraping, difficulty locking or a door that does not sit squarely when closed.
Alignment problems can be related to roller adjustment, worn components, track problems or movement within the door system.
Correct adjustment helps the door slide, close and lock more effectively.
A sliding door that moves smoothly but does not lock correctly still needs attention.
The problem may involve the lock, handle, keeper or alignment between the moving door and the frame.
A door that has dropped slightly because of worn rollers can also cause the locking points to stop lining up correctly. This is why replacing a lock without checking the door alignment may not solve the underlying problem.
Seals and gaskets help control draughts, rattling, water penetration and contact between different parts of the sliding door.
Over time, seals can become brittle, loose, compressed or damaged.
Where suitable replacement components are available, damaged seals and gaskets can be replaced as part of the repair.
Large aluminium sliding doors contain substantial areas of glass. Impact, accidental damage, thermal stress and other causes can result in cracked or broken panes.
The replacement glass must be appropriate for the application and installed correctly into the aluminium frame.
For more information, see our glass repair and replacement services.
Different symptoms require different repairs. Our approach is to identify the faulty component rather than assuming every difficult sliding door simply needs new rollers.
Worn rollers are one of the most common reasons an aluminium sliding door becomes difficult to operate.
Depending on the door system and condition, the repair may involve removing or safely supporting the sliding panel, accessing the roller assemblies, replacing suitable components, adjusting the door and testing its movement.
Signs that your sliding door rollers may require attention include:
The condition of the track should also be checked when replacing rollers. New rollers operating on a badly damaged track may not provide a satisfactory long-term result.
Track damage should not be ignored.
A worn or damaged running surface can make the sliding door difficult to operate and may contribute to premature roller failure.
Depending on the condition of the system, sliding door track repairs may involve cleaning, correcting minor problems, fitting suitable repair components or replacing damaged sections where practical.
Where both the rollers and track are damaged, repairing them together may provide a better result than treating only one component.
Not every heavy or poorly closing door requires complete component replacement.
Some aluminium sliding doors need professional adjustment and realignment.
The door may have dropped, shifted or become uneven over time. Adjustment can help correct:
The door should be tested after adjustment to make sure it slides, closes and locks correctly.
Locks and handles are used every time the door is opened, closed or secured, making them common wear points.
We assess problems such as loose handles, damaged locking mechanisms, locks that no longer engage and handles that are difficult to operate.
Importantly, we also check whether the problem is being caused by poor door alignment.
If the door itself is sitting too low or too high, replacing the lock alone may not correct the problem.
A closed sliding door should fit properly against its seals.
Worn or missing seals may contribute to:
We can inspect the existing seals and determine whether adjustment, reseating or replacement is appropriate.
A broken sliding door pane needs to be dealt with carefully because door glass is generally much larger than ordinary window glass.
The correct replacement depends on the size, location, existing glazing system and applicable safety-glazing requirements.
Not every aluminium sliding door uses the same rollers, tracks, profiles or operating arrangement. Identifying the door system helps determine the appropriate repair.
Two-panel patio sliding doors are common in South African homes.
A typical OX configuration consists of one fixed panel and one sliding panel.
Common repairs include roller replacement, track repairs, adjustment, lock and handle repairs, seal replacement and glass replacement.
Larger OXXO sliding door systems typically have fixed outer panels and two central sliding panels.
Because the moving panels can be larger and heavier, correct roller operation, track condition and alignment become particularly important.
Sigmadoors has experience with standard aluminium patio sliding door systems such as Icon-type doors.
We can assess common operating problems involving rollers, tracks, handles, locks, alignment and glazing.
Palace and other high-performance aluminium sliding systems generally use larger profiles and may contain significantly larger glass panels.
These systems require careful assessment because the weight of the moving panels places greater demands on the rollers, tracks and operating hardware.
At Sigmadoors, aluminium sliding door repair prices depend on the type and size of the sliding door, the problem and the replacement parts required. In Johannesburg, Pretoria and across Gauteng, minor sliding door adjustments generally start from around R850, while repairs involving rollers, tracks, locks, handles or glass can cost from approximately R850 to R3 500+, depending on the work required.

A faulty aluminium sliding door does not automatically need to be replaced.
In many cases, the aluminium frame and glass may still be in usable condition while the rollers, locks, handles or seals have worn out.
Repair is often worth considering when:
Replacement may be worth considering when:
Because Sigmadoors also supplies and installs aluminium sliding doors, we can advise whether repairing the existing sliding door or replacing it is the more practical option.
Explain the problem: heavy door, broken rollers, damaged track, faulty lock, broken glass or another issue.
Where possible, send photographs of the complete sliding door as well as close-ups of the damaged area.
We determine which parts of the sliding system require attention, including the rollers, track, locks, handles, seals, glass and alignment.
The required work and replacement components can then be identified before the repair proceeds.
The affected components are repaired, adjusted or replaced as required.
The door is checked for smooth sliding, correct closing, alignment and locking.

Aluminium sliding doors are different from ordinary internal doors. Their performance depends on the relationship between the aluminium profiles, rollers, tracks, glass, locks, handles, seals and overall alignment.
Sigmadoors brings over 20 years of aluminium experience to the assessment and repair of aluminium doors and windows.
Our sliding door repair service focuses on finding the actual problem and determining an appropriate repair rather than replacing components unnecessarily.
Worn rollers are a common cause, but they are not the only possibility. Damaged tracks, poor adjustment, dirt, misalignment or damaged components can also make a sliding door difficult to move. The door should be assessed before deciding which parts need replacement.
In many aluminium sliding door systems, worn rollers can be replaced. The correct replacement depends on the existing door system and availability of compatible components.
The track should also be inspected because damaged tracks can shorten the life of replacement rollers.
Common signs include a door becoming heavy, rough or noisy, scraping along the bottom, moving unevenly or dropping out of alignment.
Some track problems can be repaired, while severe damage may require more extensive remedial work or replacement. The appropriate solution depends on the track design and extent of damage.
Possible causes include damaged rollers, incorrectly adjusted rollers, track damage or alignment problems. Repeatedly putting the door back on the track without correcting the cause may not solve the problem.
The door may have dropped because of worn rollers or incorrect roller adjustment. Track damage or alignment problems can also cause scraping.
The lock itself may be damaged, but door alignment is another common cause. If the sliding panel has dropped or shifted, the lock and keeper may no longer line up correctly.
Yes. Glass can often be replaced without replacing the complete aluminium sliding door, provided the frame and glazing system remain suitable.
The correct glass specification should be selected for the application and applicable safety requirements.
The cost depends on the fault and components required. Adjustment, roller replacement, track repairs, locks, handles and glass replacement all involve different materials and labour.
Sending clear photographs of the door and damaged components can help with the initial assessment.
Yes. Sigmadoors provides aluminium sliding door repairs in Johannesburg and surrounding areas including Sandton, Randburg, Fourways, Bryanston, Midrand and other parts of Gauteng.
Yes. Our Gauteng service area includes Pretoria and Centurion, subject to the specific location and repair requirements.
If the frame is still in good condition and the problem is limited to rollers, tracks, hardware, seals, alignment or glass, repair may be the more economical option.
If the aluminium system is badly damaged, distorted or requires extensive repairs, replacement may make more sense.
