Sash Windows
We supply and install premium sash windows in timber and wood-effect UPVC. Our Bygone Collection offers authentic designs with enhanced security features, including Secured by Design endorsement. Each window combines traditional aesthetics with modern thermal efficiency, reducing heat loss by 74% compared to single-glazed alternatives. Custom options include period architraves and stone detailing.
Composite Doors
Our composite doors feature 48mm timber cores with high-security locking systems and A+ energy efficiency ratings. Available in 12 colour options and various styles, they combine durability with aesthetic appeal. Designs include low thresholds for accessibility and can incorporate stained glass features while maintaining modern security standards.
Bi-Fold Doors
Aluminium and timber bi-fold doors create seamless indoor-outdoor transitions. Custom configurations allow stacking to left, right, or both sides, with options to replace entire walls. Our installations maximise natural light and space, featuring weatherproof seals and multi-point locking systems for security and energy efficiency.
Window Replacement
We offer complete window replacement services using premium materials from Evolution, Origin, and Solidor. Our process includes no-obligation consultations, bespoke measurements, and FENSA-compliant installations.
