Sash Windows

As London’s original box sash window company, we have spent over 30 years delighting our customers with beautiful bespoke sash windows. Hand-crafted from premium quality, solid African hardwood, our sash windows capture the charm and authenticity of period windows while offering exceptional levels of comfort, security and performance. Built to last, our windows are made using traditional joinery methods and only the finest materials, creating a stunning finish for your home.

 

Glazing

 Our range of bespoke sash windows features double glazed safety glass as standard which can be tailored to your exact requirements, incorporating other glazing styles and specifications such as toughened and laminated glass, acoustic glass, and textured, obscured or stained glass.

Mouldings

 All of our traditional timber windows feature authentic mouldings 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 and horns are matched to existing features.

Colours

 All of our sash windows can be finished in the exact shade of your choice. We use high pigment, resin-rich microporous paint by British paint experts Farrow & Ball, renowned for their beautiful, premium quality paints and stunning, unmatched shades since 1946.
