We are proud to manufacture all our new timber windows and doors in the UK, in our workshops in Bracknell, Berkshire.

Which? Trusted Trader

In 1994, The Sash Window Workshop started operating out of a small converted pig shed in Ascot, Berkshire. The business has grown over the last 30 years and now trades out of two large purpose-built workshops in Bracknell, Berkshire.

We manufacture all our timber windows and doors

We pride ourselves on manufacturing all our timber windows and doors at our premises in Bracknell. By manufacturing our windows and doors in house, we can ensure that the high standards our customers expect are maintained.

This also means that our prospective customers are able to visit us for a guided tour. We encourage you to call us to book a visit to our factories in Bracknell, allowing you to meet our staff and see what we do and how we do it.

Our workshop employees are all highly skilled craftsmen who will manufacture your new windows and doors to the highest quality.

All our windows and doors are bespoke and made to order, designed to retain the character and beauty of traditional timber windows and doors.

We have a state of the art production capability which, alongside our high attention to detail and craftsmanship, enables us to make the very best windows and doors.

Fully Factory Finished Timber Windows and Doors

Due to growing demand for our windows and doors, in 2021 we made a one million pound investment in our production capabilities.

We doubled the size of our production space by taking on a second industrial unit and also invested in new equipment.

This included buying a second CNC machine for manufacturing component parts and a fully automated paint line, with robotic painting and specialist drying facility, which enables us to deliver an outstanding paint finish to the highest technical standards.
