Sash & Case Window Repair & Restoration

Sash and case windows are one of the defining features of many traditional Scottish properties.

When properly maintained, original timber windows can provide decades of additional service while preserving the character and value of a property.

Unfortunately, many older windows suffer from issues such as broken sash cords, rattling frames, draughts, failed paint systems, sticking sashes and localised timber decay.

In many cases, these problems can be resolved through careful repair and restoration, avoiding the unnecessary replacement of original historic fabric.

At The Period Property Workshop, we provide sash and case window repair and restoration services throughout Dundee, Angus, Perthshire, Fife and the wider Tayside region

Why Repair Rather Than Replace?

Original sash and case windows were often made using high-quality timber and traditional joinery methods.
