Our Versatile
Timber Sash Windows

Our new sash window and boxes are manufactured using the traditional cord and counter weight or assisted sash balance systems. Optimised for smoothness, durability and ideal for enhancing the period charm of your property.

Our new timber sashes can also be installed into the existing frames. This is an excellent solution for upgrading your existing single glazed or rotten sashes whilst keeping treasured historical fabric, ideal for listed buildings and conservation areas.


Bespoke Design

Every Sash Window is different, every customer has different requirements. William Richards Sash Windows thoroughly surveys and designs each and every sash window to suit. Our clients can customise everything from glazing bars and moulding to paint finishes and horn details. By taking everything into account, we make sure your sash windows are designed perfectly to suit your style and building requirements.

Premium Timber

Sustainably sourced, all of our sash windows are constructed using the hardwood, Sapele. Our extensive research and experience working with this timber has ensured it passes the test of time. It’s low movement, high density characteristics makes for lasting durability and the porous grain works in harmony with our quality paint finishes

Traditionally manufactured

Our talented team of time served bench joiners, machinists, glaziers and finishers utilise a blend of classic techniques and state of the art machinery to produce sash windows that are built with meticulous detail proven to stand the test of time. Each sash window goes through an in depth quality check from our production manager to ensure it meets our quality standards.

Paint Finishes That Protect

Our timber spraying specialists utilise our state-of-the-art spray booth. All of our timber sash windows go through a 5 stage paint system starting with an impregnating base coat to seal end grain followed by 4 coats of micro porous primers and top coats. This results in maximum durability with low maintenance – we ensure our timber sash windows can stand all the weather variants the UK can throw at them.

Effective, Subtle Glazing

We glaze our sash windows with state of the art glass units to suit every specification. Whether your sashes are being installed into the existing frames of a listed building or we are producing new boxes for a modern, eco friendly home. From thermaglass lined, insulated glass units to vacuum insulated laminate we use the perfect glass solution to suit your specification.
