Casement Windows

Our traditional hinged casement windows are the result of over 40 years of innovation and product refinement.

Using superior quality solid hardwood, our skilled craftsmen use traditional joinery methods to create a window that marries premium performance with bespoke designs that remain sympathetic to the original features of your character or period property.

Incorporating only the finest materials, craftsmanship and finishes, our casement windows are designed to delight every time. 


We make all our own glazing units to ensure maximum insulation and sound proofing properties. Double glazed safety glass as standard, we can also be tailor the glazing to your exact requirements – incorporating other glazing styles and specifications such as toughened and laminated glass, acoustic glass, and textured, obscured or stained glass.


 All of our traditional timber windows feature authentic moulding that will perfectly complement your property. Our internal mouldings are created bespoke to match the original mouldings in your home, while outside detailing such as glazing bars are matched to existing features.

We can also finish our windows in your preferred colour. Just quote us your chosen paint and reference and we will make an exterior quality paint to match.
