Services
Sash window refurbishment
Our sash window refurbishment service revitalises period timber windows using traditional techniques combined with modern materials. We replace rotten sections with durable Tricoya wood, reinstate functionality, and apply protective coatings to ensure longevity. This process preserves historical authenticity while improving thermal efficiency and durability for Grade 2 listed properties and modern homes alike.
Double glazing retrofit
We install ultra-thin vacuum double glazing units into existing sash windows without altering their appearance. This energy-efficient solution reduces heat loss by up to 80% compared to single glazing while maintaining the original character of period properties. The system includes frame reinforcement and weight adjustments for smooth operation.
Draught-proofing
Our draught-proofing solutions seal gaps in sash windows using discreet compression seals and weatherstripping. This energy-saving measure reduces heat loss by up to 10%, lowers energy bills, and improves comfort without compromising the window's historical integrity or requiring major structural changes.
Listed building restoration
Specialising in conservation-compliant repairs for Grade 2 listed properties, we use traditional materials and techniques to restore windows while maintaining historical accuracy. Our methods include like-for-like timber replacements, putty restoration, and sympathetic upgrades that meet modern performance standards without altering original features.
Bay window repair
We repair and restore bay windows of all styles using rot-resistant materials and traditional joinery techniques. Our process includes structural reinforcement, draught-proofing, and protective coatings to extend the lifespan of these complex window systems while maintaining their architectural character.
