Sash Window Renovation
Our sash window renovation service restores aged timber windows to full functionality while preserving their historical character. We repair damaged timbers, replace rotten sections, and install draught-proofing systems to enhance energy efficiency. This service is ideal for properties in conservation areas seeking to retain original features without compromising performance.
Sash Window Replacement
Replacement sash windows are crafted using traditional joinery techniques with Accoya timber for durability. We replicate original designs to match architectural styles, ensuring compliance with listed building regulations. Modern benefits include heavy-duty hardware and low-maintenance finishes for long-term performance.
Draught Proofing
Our Super-Glide Draught Proofing System reduces heat loss by up to 98% by sealing gaps around sash windows. Brush pile strips integrated into timber frames eliminate rattles while maintaining smooth operation. This cost-effective solution improves thermal efficiency and reduces noise pollution without altering window aesthetics.
Slim Double Glazing
Slim double glazing retrofits existing sash windows with energy-efficient units that mimic single-glazed appearance. We install Heritage Slim-lite units within repaired box frames, combining traditional looks with modern insulation. This option reduces energy bills and noise while preserving historical integrity.
Secondary Glazing
Secondary glazing adds an internal timber frame with glass to existing windows, reducing noise by up to 80%. This solution maintains original windows while improving thermal efficiency. Custom-made units fit all shapes and sizes, ideal for listed buildings where external alterations are restricted.

Keith, the boss, was incredibly helpful and informative throughout the entire process, offering us a highly competitive price on four large sash windows that are simply stunning. They look fantastic, and thanks to the double-glazed, gas-filled glass, we no longer experience condensation and are saving on heating costs. His team are true craftsmen, taking great pride in preserving the heritage and skills that maintain the charm of so many Leamington homes. We only wish we had had these windows installed years ago.

They replaced 7 windows last Autumn. The quality and build of the windows is high. The onsite workmen are truly craftsmen, and - although the job overran in time - it was a quality job. Unfortunately, the finishing off , which they seem to subcontract is appalling and they try to fob me off every time I call or e-mail. The pointing is outstanding, the render around one window is still waiting to be finished, they never supplied the pole to open the top windows, and their subcontractor appears to have painted some of the windows shut. 9 months after the bulk of the work was finished, my house still looks a mess.
