Box Sash Windows

One of the most traditional windows, they grace some of the most beautiful homes in the country. We specialise in replacing these originals when the time comes. Weights & pulleys ensure the windows are easier to open, energy efficient, secure and soundproof without looking out of place for the style of the property.

Stay true to the original.

Working together, we ensure that the history of your property is respected and the overall appearance enhanced. The finished product will accurately replicate the original style. Our box sash window operates on sash cords, pulleys and sash weights.

Window Insulation

Fully bespoke.

Each window is made to order, measured and designed to match the exact specifications of your property and manufactured by skilled craftsmen in our purpose built workshop.

Refurbish your existing windows.

Our expert craftsmanship means that if the main frame is in good condition we can remove your existing sash, measure and manufacture brand-new sashes, and change the existing beads, cord and all hardware. This provides a cost-effective method that allows you to beautifully enhance your windows, whilst even upgrading to double-glazed units!
