Services
Secondary Glazing
Our secondary glazing solutions add an extra glass layer to existing windows, improving thermal efficiency by up to 60% while maintaining original aesthetics. This discreet upgrade reduces noise pollution and enhances security without altering historic window structures. Ideal for conservation areas where original features must remain untouched.
Traditional Leaded Lights
We craft authentic leaded light windows using traditional methods, with individual glass quarrels joined by lead cames. Our specialists replicate period-accurate designs for new installations or replacements. Each panel is handmade to match original specifications, ensuring historical accuracy and visual continuity.
Window Restoration
Our restoration service addresses damaged leaded windows through careful dismantling, re-leading, and reinstallation. We preserve as much original material as possible while reinforcing structural integrity. This process extends window lifespan and maintains architectural authenticity for listed buildings.
Antique Glass Supply
We source and supply authentic antique glass produced using traditional mouth-blown techniques. This includes muff and cylinder glass with characteristic imperfections that replicate 17th-19th century window appearance. Our materials help maintain historical accuracy in restoration projects.
Draught Proofing
Our draught-proofing solutions address air leakage in historic windows without compromising original features. We install discreet seals and secondary glazing systems that reduce heat loss by up to 70% while maintaining visual integrity. This improves energy efficiency and indoor comfort.
