Commercial Glazing Company & Trade Glaziers London & Surrey
Window Fitters Ltd operates as a specialist glazing company and commercial glazing contractor, providing experienced glaziers for main contractors, housebuilders, and property management firms across South London, Surrey, and Greater London. Headquartered in Croydon, our directly employed trade glazier workforce delivers structural glass facades, commercial shopfronts, and multi-unit residential window packages.
Professional B2B Glazing Contractors & Multi-Unit Subcontractors
As an independent glazing contractor, we bid on public and private commercial tenders. We operate under standard JCT subcontract agreements, working directly alongside principal contractors to maintain site progress and meet key milestone schedules.
Commercial Curtain Wall & Structural Glass Installations
We supply, install, and maintain thermally broken aluminium curtain walling systems, including stick curtain walling and structural silicone glazing (SSG) elevations. Engineered for high wind load resistance, thermal isolation, and rainwater management, our curtain wall packages optimise commercial building envelopes.
Toughened Glass Shopfronts & Interior Office Partition Systems
We fit frameless toughened glass shopfront screens, commercial entrance doorsets, and back-painted interior glass wall panels. For corporate office fit-outs, we install single and double-glazed acoustic partition screens that diffuse sound while maximising internal natural light.
Experienced Trade Glaziers & On-Site Fenestration Technicians
Our team of trade glaziers handles heavy glass lifting, mechanical positioning, vacuum suction maneuvering, structural anchoring, and weather-seal application. Every glazier holds a valid CSCS card and operates under strict health and safety protocols.
Quality Governance & Building Standards Compliance (Document L, Q & B)
Every commercial project delivered by Window Fitters Ltd complies strictly with UK Building Regulations. We verify thermal insulation under Document L, safety glass integrity under Document K (BS EN 12150), security ratings under Document Q (PAS 24), and fire containment under Document B (FD30/FD60 assemblies).
Comprehensive Project Specification & Architectural Review
Our technical team reviews architectural drawings, structural calculations, and window schedules before site mobilisation. We coordinate directly with Local Authority Building Control (LABC) or approved private inspectors to secure legal completion certificates.
