Before & After






Timber Sash Windows Surrey | Traditional Repair & Restoration


Timber sash windows are a defining feature of period properties throughout Surrey, from historic market towns to rural villages and commuter suburbs. Areas such as Ashtead, Cobham, Dorking, Epsom, Esher, Fetcham, Guildford, Leatherhead, Redhill, Reigate, Weybridge, and surrounding locations contain large numbers of Georgian, Victorian, and Edwardian homes where traditional timber sash windows remain central to architectural character.
Surrey’s development from the seventeenth century onwards closely followed the rise of the timber sash window. Georgian timber sash windows in Surrey are typically six-over-six in configuration, with slim glazing bars and refined proportions. Victorian timber sash windows often feature two-over-two layouts, larger panes, and decorative horns, while Edwardian properties introduced wider window openings designed to maximise natural light.
Traditional timber sash windows in Surrey were constructed using oak in earlier buildings and pine in later periods. These windows were designed for long-term maintenance, which is why many original frames, sashes, and counterweight systems can still be restored rather than replaced.
Much of Surrey is covered by conservation areas or contains listed buildings. Local planning authorities strongly favour the repair and refurbishment of original timber sash windows or accurate like-for-like replacements. Services such as timber sash window restoration, draught proofing, secondary glazing, and overhaul are commonly approved where external appearance is preserved.
Timber sash windows in Surrey play a key role in maintaining period character, meeting planning requirements, and protecting long-term property value.
