Aluminium Window Repairs in Manchester
Specialist repair and maintenance for aluminium windows, mechanisms and hardware.
Based in Manchester, Engiglass provides specialist aluminium window repairs across Manchester and Greater Manchester. We diagnose and repair aluminium window systems including Schuco, Roto, Siegenia, Winkhaus and GU, covering everything from handles, hinges and locking mechanisms to alignment and sealing issues. Where replacement parts are available, we source the correct components for the existing system rather than replacing the entire window unnecessarily.
Why Choose a Specialist for Aluminium Window Repairs?
Aluminium windows often use proprietary or system-specific hardware, meaning the correct replacement part is not always obvious. A faulty handle, hinge or locking mechanism can also be caused by misalignment elsewhere in the window.
Our approach is to diagnose the underlying problem before recommending a repair or replacement. We inspect the hardware, frame alignment and locking points to determine what is actually causing the issue. Where possible, we repair or replace the failed component rather than replacing the complete window.


Aluminium Window Handle, Lock & Hinge Repairs
Handles | Locking Mechanisms | Hinges | Tilt & Turn | Espagnolette & Gear Mechanisms
We repair and replace faulty aluminium window hardware, including handles, locking mechanisms, hinges and tilt-and-turn components. If a window is difficult to operate, will not close correctly, is stuck open or has a faulty handle, we can inspect the mechanism and identify the failed component.
Aluminium Window Alignment & Adjustment
Protect the Value of Your Aluminium Windows
A window that is difficult to close or lock is not necessarily suffering from a failed mechanism. Frame movement, worn hinges or incorrect adjustment can place excessive pressure on the locking points.
We carry out aluminium window alignment, adjustment and mechanical calibration to restore smooth operation and correct engagement of the locking system.


Aluminium Window Seal & Gasket Replacement
Energy-Efficient & Draft-Free Living
Worn or damaged seals can cause draughts, water ingress and poor weather performance. We inspect and replace suitable window gaskets, seals and glazing components where required.
Condensation between the glass panes can indicate a failed sealed glass unit. Where this occurs, we can assess the glass unit separately and advise whether replacement is required.
