We deliver secure, regulation-compliant window and door systems across the South East. Explore our recent commercial projects below.
We installed aluminium shopfront systems and automatic sliding doors across multiple dealership sites in Gillingham, Wimbledon, and Enfield. Built for high-traffic commercial use, the systems included Commercial Grade glazing, secure framing, and full public access compliance.
We carried out a full timber sash window replacement at this listed school site in Peckham. All windows were custom-made to match heritage standards while improving acoustic control, internal comfort, and security.
Drone footage was captured outside of school hours with full permission.
We installed new uPVC windows, high-security external doors, and a purpose-built porch at St Joseph’s Primary School in Rotherhithe. The full upgrade was delivered over the school holidays, with all works completed to educational site safety standards.
We cut into existing structural openings and installed larger aluminium-framed glazing units to maximise natural light and modernise the office façade. All works were completed with full structural support, dust control, and clean commercial finishes throughout.
This project included a full property upgrade using grey wood grain-effect uPVC windows. The install improved site security, aesthetic consistency, and reduced future maintenance — ideal for a tenanted commercial property.
We replaced all existing units at the Unilever Kingston headquarters with thermally broken grey aluminium frames. The upgrade modernised the building’s appearance, reduced external deterioration, and met specification for commercial energy standards.
We work with schools, developers, landlords, and public-sector clients across London and the South East. Submit your project details below — we’ll respond within one working day.
