Sash & Case Window Restoration

Traditional sash and case windows are an important feature of Edinburgh’s Georgian and Victorian architecture. The right approach begins with inspecting the condition of the timber, glazing, cords, pulleys, ironmongery and surrounding masonry. A repair-first assessment can often retain sound original material while addressing the particular fault.

Understanding the work

Restoration may involve dismantling sashes, removing failed coatings, repairing localised decay, renewing cords and rebalancing the weights. The goal is to preserve original joinery wherever it remains serviceable.

Choosing an appropriate repair

For historic properties, matching existing profiles, mouldings and glazing details is especially important. Photograph and document original features before work begins.

What to check before commissioning work

• Identify the precise fault and whether it affects one window or several.
• Check for moisture ingress and any underlying masonry problems.
• Confirm whether the property is listed or within a conservation area.
• Request a clear written specification of proposed repairs and materials.
• Retain original timber and fittings where practical.

Edinburgh properties and traditional details

Windows in New Town townhouses, Marchmont tenements, Stockbridge flats and Victorian villas may share a sash-and-case construction but differ in their glazing bars, timber profiles, dimensions and access requirements. A suitable solution should respond to the actual window, not simply its postcode.
