Timber Sash Windows
Our timber sash windows combine traditional aesthetics with modern performance. Using engineered redwood, meranti or oak, we create warp-resistant windows that maintain period character while achieving superior thermal efficiency. Each window features discreet multi-point locking systems and double glazing with argon gas filling, available in traditional box sash or spring-balanced designs. We match original slim sectional sizes for authentic restoration.
Casement Windows
Bespoke casement windows crafted from engineered timber ensure lasting durability and security. Available as flush or Edwardian styles, our windows incorporate advanced locking systems and energy-efficient glazing. The design retains period features while offering modern benefits including weather resistance and low maintenance requirements. Custom options include astragal bars, leaded lights and dual-colour finishes.
Entrance Doors
Handcrafted entrance doors made from warp-resistant engineered timber provide security and aesthetic appeal. Available in contemporary or period styles with options for stained glass, sidelights and multi-point locking systems. Factory-finished with 8-year paint guarantees, our doors combine traditional craftsmanship with modern insulation properties and custom design possibilities.
Bi-Fold/French Doors
Timber bi-fold and French doors create seamless indoor-outdoor transitions. Engineered for thermal efficiency with krypton gas-filled glazing, these doors feature concealed hinges and security locks. Bi-fold systems offer unobstructed walkways with flush floor tracks, while French doors maintain traditional elegance with adjustable opening configurations for optimal space planning.
Project Management
End-to-end project management from consultation to completion ensures seamless installations. Our experienced teams handle plastering, rendering and finishing touches alongside window/door fitting. We provide realistic timelines, comprehensive handovers and after-sales support, maintaining quality control throughout the process for both residential and commercial properties.
