Brand-Specific Window & Door Repairs

Finding the right replacement part can be difficult when a window or door uses an older, discontinued or less common system. Based in Manchester, Engiglass provides specialist brand-specific repairs across Manchester and Greater Manchester, identifying and sourcing compatible components for aluminium and uPVC windows and doors. We assess the existing hardware, identify the appropriate replacement and carry out the repair where possible, helping to restore the original installation without unnecessary full replacement.

Specialist Component Replacement for Aluminium & uPVC Systems

We repair and replace a wide range of window and door hardware, including multi-point locks, handles, hinges, tilt-and-turn gearboxes, friction stays and sliding door rollers. Each system has its own hardware and specifications, so we identify the existing component before sourcing a suitable replacement.

Brands & Systems We Work With

We work with systems and hardware from manufacturers including Schüco, Roto, Hautau, GU, Maco, Siegenia, Winkhaus and Dorma, as well as other European manufacturers.

Servicing, Adjustments & Mechanical Realignment

We also provide servicing, adjustment and mechanical realignment for windows and doors where the problem is related to operation, alignment or worn hardware. This includes stiff tilt-and-turn windows, misaligned doors and sliding mechanisms that no longer operate smoothly.

Obsolete & Hard-to-Find Replacement Parts

Older systems can be difficult to repair when the original hardware is no longer readily available. We identify existing components and work with specialist suppliers to source genuine, compatible or suitable replacement parts where available.

​

Our aim is to repair the existing installation wherever a reliable solution is possible, rather than replacing a complete window or door unnecessarily.
