Aluminium Window Repair – Professional Adjustment and Servicing
Aluminium windows are built to last decades. But even quality systems gradually lose their adjustment. If your aluminium window is harder to close, catches on the frame, or lets in drafts – it needs professional attention, not replacement.
Why do aluminium windows stop working smoothly?
Aluminium window hardware operates under daily load. The sash presses against the frame hundreds of times per year. Over time, hinges shift, the compression level changes, and the seal loses its elasticity. The window starts to catch, resist, or let cold air in – not because it is worn out, but because it needs adjustment.
The difference between aluminium and PVC: aluminium frames are stiffer and less forgiving of misalignment. A 1 mm shift in hinge position creates noticeably uneven pressure across the whole sash.
What aluminium window repair includes
The technician performs: hinge adjustment and load redistribution, compression level setting, hardware cleaning and lubrication, gasket condition check, and sash geometry verification. In most cases, one visit is enough to fully restore smooth operation.
Adjustment vs full hardware replacement
Most aluminium window problems are solved by adjustment, not part replacement. Technician diagnoses on-site – if hardware is worn beyond adjustment, he recommends replacement only for the specific components that have failed. No unnecessary work.
Cost and warranty
Aluminium window adjustment: from 60 PLN. Hardware replacement – priced individually after diagnostics. Warranty up to 5 years on all work performed. Diagnostics and first consultation are free.
Scope of aluminum window services
Repairing aluminum systems requires knowledge of specific products – our technicians have experience with Schüco, Aluprof, and other systems
Hardware replacement in aluminum systems
Aluminum window hardware is system-specific – each manufacturer uses its own solutions, incompatible with other systems. We source and replace hardware matched to your system: Schüco, Aluprof, Reynaers, Heroal, and others.
Adjustment and replacement of aluminum hinges
Aluminum window hinges offer three-axis adjustment – position, compression, and level. Precise adjustment eliminates sash rubbing and closing issues. Replacement carried out in cases of permanent damage.
Repair of HST sliding mechanisms
HST (lift-and-slide) systems require precise adjustment of sliding force and compression. We repair damaged mechanisms, replace rollers and track components.
Seal replacement for aluminum profiles
Aluminum window seals (EPDM or TPE) are fitted to the groove in the profile. We replace seals compatible with the specific system, preserving the window's insulation performance.
Glass unit replacement
Condensation between the panes in an aluminum window is not the frame's fault. We replace the failed glass unit – including in structural glazing and curtain wall systems.
Multi-point lock servicing
Aluminum windows in office and premium systems often feature multi-point locks. We repair the mechanism or replace the lock with one compatible with the system.
Aluminium window servicing – what you should know
Aluminium windows are a higher standard – repair is possible, but requires specialist knowledge and system-specific parts
Aluminium windows need a service check once a year
Aluminium fittings are precision-made but prone to grit build-up and grease wear. Annual servicing and lubrication can extend the system's lifespan by a decade or more.
HST – increasing resistance when sliding is a sign to call for service
If your HST sash is getting harder to slide – don't wait. Overloaded guide rollers wear out fast. Early adjustment costs a fraction of a full roller replacement.
Not every aluminium part is expensive
Handles, locks and seals are reasonably priced even in Schüco systems. A quote before any repair is always free – your technician will present costs with no obligation.
3D hinges – adjustment without removing the sash
Most modern aluminium hinges can be adjusted along three axes without removing the sash. A technician can complete the adjustment in 15–20 minutes.
Aluminium profiles last 40+ years
Aluminium doesn't corrode and doesn't change dimensions. A profile in good condition justifies repairing even the most expensive components – rather than replacing the whole window.
Schüco and Aluprof systems – we know them well
Our technicians have experience with the most popular aluminium systems. We bring compatible parts with us – the visit usually ends with a complete repair in a single call.
