Cantifix

What Cantifix does

Cantifix is a privately held London-based specialist contractor focused on structural glass installations, founded in 1986. The company's offering centres on high-end frameless and minimal-frame glazing systems, including glass roofs, glass walls, glass floors, and glass extensions (such as orangeries and conservatory-style structures). These products serve the premium architectural glazing segment, addressing clients seeking bespoke structural glass solutions rather than commodity fenestration.

The business operates with a small team of 11-50 employees, consistent with a specialist trade contractor model where skilled installation labour and project management represent the primary cost base. Its London headquarters and UK-centric footprint indicate a domestically focused go-to-market, with project-based revenue generated through bespoke installations for residential and commercial clients. The product mix—structural glazing, sky-frame systems, and roof/wall/floor glazing—suggests a project-based revenue model with contract values tied to installation scope, material specifications, and engineering complexity.

Cantifix is privately held, unlisted, and has operated continuously for nearly four decades, signalling a durable niche presence. Information on customers, pricing, partnerships, ownership, management, and financial performance is largely absent from the available source set, constraining deeper commercial analysis.
