We manufacture all our timber windows and doors

We pride ourselves on the fact that we manufacture all our timber windows and doors at our premises in Bracknell and keep our work in house.

All our windows and doors are bespoke and made to order. By manufacturing our windows and doors in house, we are able to maintain the highest standards.

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

We encourage our prospective customers, to visit us at our factories in Bracknell, meet our staff, and take a guided tour, so we can show you in person what we do and how we do it.

Fully Factory Finished Windows and Doors

Due to growing demand for our windows and doors, in 2021 we made a £1 million investment in our production capabilities.

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

We now have a state of the art production capability which, alongside our high attention to detail and craftsmanship, gives us what we believe to be an unbeatable combination to make the very best windows and doors.
