AluK Specialists

Expert AluK Door Repair in London

AluK is a Belgian aluminium systems manufacturer with a significant presence in the UK market. Their systems are widely specified in both new-build residential developments and commercial refurbishment projects, making them one of the more commonly encountered brands in London properties.

The AluK BSF70 is their flagship bifold door system — a robust aluminium bifold found in thousands of London homes and commercial properties. Their sliding systems are also widely installed, particularly in apartment developments and modern residential extensions.

AluK systems are generally well-constructed, but like all aluminium door systems, they develop faults with age and use. Roller wear, seal degradation, misalignment and locking failures are the most common issues. Our engineers have experience with the full AluK range and carry parts for the most common systems.

Common Questions

AluK Door Repair FAQs

My AluK bifold has a panel that won't fold flat — what's causing this?

This is typically a pivot or hinge alignment issue — the panels are out of square with each other, preventing them from folding correctly. Adjustment of the pivot and top roller hardware usually resolves this without the need for component replacement.

My AluK sliding door leaves a gap at the top when closed — is this fixable?

Yes. A gap at the top of a closed sliding door is usually caused by worn rollers allowing the panel to drop, or by top guide wear. Roller replacement and adjustment restores correct seal compression across the full height of the door.

How do I know if my door is AluK?

AluK branding is often found on the handle escutcheon or frame extrusion. Many AluK systems are installed through fabricators who may label the door under their own brand — our engineer can identify AluK profiles during the survey visit.

How much does AluK door repair cost?

Our £70 survey fee covers assessment and quotation. AluK repairs typically range from £250–£1,200 depending on the fault and system involved. All costs are quoted clearly before work begins.
