Services
Window Restoration
Our window restoration service carefully repairs and rejuvenates original sash windows, removing decayed timber, applying specialist hardeners, and replacing damaged components. We preserve historical character while ensuring structural integrity and longevity. The process includes sanding, priming, and applying durable finishes to protect against weathering, leaving windows both functional and aesthetically authentic.
Draught Proofing
Draught proofing eliminates cold air gaps in sash windows using discreet brush pile systems installed in parting beads and frame headers. This method improves thermal efficiency without altering the window's appearance, reducing heating costs and enhancing comfort. The process includes re-weighting sashes and installing security locks for optimal performance.
Heritage Double Glazing
Heritage double glazing integrates 12mm slim units into original sash windows, maintaining traditional slim profiles and glazing bars. This solution enhances insulation while preserving historical accuracy. Our bespoke units are crafted to match existing window designs, ensuring seamless integration and compliance with conservation area requirements.
Secondary Glazing
Secondary glazing involves installing discreet internal units to improve thermal performance without altering original windows. These units blend seamlessly with period features, offering noise reduction and energy efficiency. The system is ideal for listed buildings where external modifications are restricted, providing modern comfort with minimal visual impact.
Bespoke Joinery
Our joinery division creates custom timber windows, doors, and gates using traditional techniques. Each piece is crafted to match original architectural details, ensuring compatibility with period properties. Materials are selected for durability and aesthetic appeal, with options for decorative glazing bars and heritage-style finishes to complement historical designs.
