System thinking
GI reviews the opening, use, glass, hardware, finish and installation interface before final scope.

GI capabilities
New aluminium and glass projects, repair work and professional support—separated clearly so each enquiry starts in the right place.
Casement, sliding and other project-appropriate window configurations with glass, hardware and finish coordinated as one system.
Sliding, stacking, hinged and entrance systems for residential and commercial openings.
Showers, balustrades, partitions, doors and specialist glass applications designed around the actual site condition.
Replacement glazing assessed against the opening, application, safety need and surrounding system.
Fault-finding and repair for difficult doors, windows, locks, handles, hinges, rollers, seals and alignment.
Assessment-led colour, hardware and functional restoration where replacement may not be the only sensible route.
Scope discipline
GI reviews the opening, use, glass, hardware, finish and installation interface before final scope.
Quotations should state what is included, excluded, provisional or subject to site verification.
Access, openings, thresholds, supporting work and programme dependencies are brought into the conversation early.
Start with the project brief so GI can assess fit, scope and next steps.
