While uPVC offers an entry-level upfront price and timber remains essential for listed period facades, aluminium delivers the greatest long-term return on investment for contemporary London homeowners. Its structural strength allows for slimmer frames, bigger panes of glass, and decades of maintenance-free performance.
All frames are treated with marine-grade Qualicoat powder coatings designed to resist weathering, fading, and urban pollutants. Choose from our standard architectural palette or specify any custom RAL shade.
The definitive contemporary UK finish. Pairs seamlessly with modern extensions, cedar cladding, and rendered brickwork.

Every Durajoin window is custom fabricated. Transparent estimates depend on your structural requirements:
Standard windows (under 1.2m x 1.2m) match baseline figures. Oversized picture windows or large casements require structural aluminium reinforcement.
Upgrading to acoustic laminate (+15–20% per pane) dampens busy London road, rail, and flight corridor noise up to 42dB.
Ground-floor installations have lower labor overheads than higher-storey bays or listed buildings requiring custom scaffolding and specialist stone removal.
Standard finishes (Anthracite Grey, Jet Black, Pure White) are stocked for fast turnaround. Custom RAL shades and dual-tones add a minor paint run setup cost.

Yes. All our bespoke aluminium windows are engineered with advanced polyamide thermal break technology and fitted with high-performance double or triple glazing. They comfortably meet or exceed current UK Building Regulations (Part L), achieving low U-values to keep your home warm in winter and reduce energy bills.
Aluminium windows have an expected lifespan of 30 to 45 years or more. Unlike timber, they will not warp, rot, or swell, and unlike standard uPVC, they do not degrade or discolor under UV exposure. A durable powder-coated finish ensures minimal maintenance beyond occasional cleaning with soapy water.
No. Older aluminium systems without thermal breaks were prone to condensation, but modern systems utilize polyamide thermal barriers that isolate the interior and exterior frames. Combined with energy-efficient argon-filled glass units, this prevents heat transfer and significantly minimizes internal condensation risks.
We manufacture and install a comprehensive range of architectural styles, including:
Slimline Casement Windows (top-hung, side-hung, fixed)
Modern Flush Casement Windows
Dual-action Tilt and Turn Windows
Contemporary Sliding Sash Windows
All systems are custom-made to your exact structural opening dimensions.
Every window is fitted with high-security multi-point locking mechanisms, internal glazing beads (preventing glass removal from outside), heavy-duty hinges, and robust locking handles. Our systems meet rigorous British security standards, including PAS 24 certification.
Yes. Our aluminium profiles can be powder-coated in any standard RAL color, including popular contemporary choices like Anthracite Grey (RAL 7016), Jet Black (RAL 9005), and textured finishes. We also provide dual-color options, allowing you to match a specific exterior tone while keeping neutral white or light grey inside.
We offer a full end-to-end service—from initial site survey and precision manufacturing to professional installation by certified fitters. For builders, developers, and architects managing their own teams, we also provide a dependable supply-only service delivered directly to your site across Greater London.
Our team serves all boroughs of Greater London—including Central, West, North, and South London—as well as project sites across Surrey and Berkshire.
Because every unit is bespoke, lead times typically range from 2 to 4 weeks following final survey sign-off and specification approval. Exact turnaround times depend on custom color finishes, specialized glass configurations, and overall order size.
