Sash Windows London were chosen to work alongside WS Builders to undertake this challenging installation of over 130 replacement windows within a strict timescale.

Why Bereco?

Bereco were able to design and supply bespoke timber windows to meet the specific and unique requirements of the project. With a consistent lead time all year round, Sash Windows London could rely on Bereco to supply the windows in time to meet the project deadline.

The Bereco Traditional Range was the ideal choice for the boy’s school; the windows are fully factory finished with extensive warranties, look in keeping with the traditional design of the property and offer high U- Values providing excellent energy performance.

A mixture of bespoke timber windows, with an All Bar design, have been installed throughout the building; large Sliding Sash Windows in Spiral Balance design with opening fanlights, Flush Casements and windows with a curved head design.

Interesting Fact

The project features bespoke Georgian style timber sliding sash windows with opening fanlights weighing almost 200 kilograms!

Special Requirements

It was essential that the replacement windows were designed to match the existing timber products in the building as closely as possible to meet the approval of The London Borough of Hammersmith and Fulham. One major requirement of the project was that the windows had to combine period aesthetics to complement the building with high-performance features to ensure a suitable school environment for over 500 pupils. Due to the nature of the project, all windows had to be supplied and installed to meet a specific completion deadline.

“We chose Bereco to supply the windows for this project as we know that the product quality and lead times are consistent which was imperative to this project.”

Beautifully constructed windows which do the job perfectly. Handled Covid disruption effectively. Installation went smoothly. All in all a job very well done. Would recommend without reservation.


Visited the showroom last year and impressed with the finish and quality. Just as delighted with the windows and back door that we ordered. They look fabulous.
