Services
Sash window repair
Our expert carpenters specialise in comprehensive sash window repairs, addressing rot treatment, frame strengthening, and hardware replacement. We employ traditional techniques combined with modern materials to restore functionality while preserving historical integrity. Each repair includes belt sanding, edge planing, and installation of new cords and furniture to ensure smooth operation.
Thermal insulation
We upgrade windows with double-glazed units featuring argon gas filling and warm-edge spacer bars achieving 1.1W/m2K U-value. Our thermal solutions reduce energy bills by 136% compared to standard units while maintaining authentic window appearance. Installation includes draught-proof beading to enhance thermal performance without altering aesthetics.
Window restoration
Specialising in historic properties, we restore centuries-old sash windows using traditional methods. Services include timber splicing, putty renewal, and balance system replacement. Our team recently revitalised 200-year-old windows at Magee Campus, University of Ulster, demonstrating expertise in preserving architectural heritage while modernising functionality.
Draught-proofing
Our draught-proofing solutions install full weather stripping systems that maintain window appearance while eliminating cold spots. The process involves precision-fitted beading and seals that reduce energy loss without affecting window operation, typically completed within 3-4 hours per window.
Security fittings
We enhance security with lockable sash fasteners and Weekes End stops that allow ventilation while preventing forced entry. Our discreet security solutions maintain traditional window aesthetics while meeting modern safety standards, with locks positioned for optimal functionality.
