Timber Windows and Doors: London

Traditional Timber Windows and Doors

The Sash Window Workshop has been replacing timber sash windows, casement windows and doors in London since 1994. We have 30 years experience working in period properties and in London Conservation Areas.

Traditional timber windows and doors were not manufactured to consistent standards as they are today. Consequently, every window and door that we repair or manufacture is different, meaning we have to pay extraordinary attention to detail. All our new wood windows and doors are therefore bespoke and made to meet your individual requirements.

Accoya Timber: 50 Years Anti-Rot Guarantee

For new wooden sash windows, casement windows and external doors, we recommend using a timber called Accoya.

Accoya is a FSC certified, sustainably sourced modified wood.  The wood is highly durable and stable, coming with a 50 year anti-rot guarantee.

This high durability means that it is designed to last and that the window or door will not require as much maintenance as some other timbers.

Having been an early adapter of Accoya, we are proud to be an Accoya approved manufacturer, demonstrating that our windows and doors are manufactured to a high standard.

When deciding on the design of your London timber windows or doors, we can also offer a wide variety of different glass and ironmongery options to meet your requirements.

Energy Efficient Windows and Doors

All our windows and doors are manufactured in our workshops in Bracknell, Berkshire by our skilled craftsmen.  We utilise the latest technology to manufacture high quality, traditional timber windows and doors to suit your home.

Our timber sash windows, casement windows and external doors all come fully factory finished. They are double glazed as standard to help improve energy efficiency and keep your home warm.

If you are unable to have standard double glazing due to planning restrictions (for example, if your home is a listed building), we can also manufacture like-for-like single glazed windows or we can install our heritage double glazing (when approved by planning permission).

All new windows and doors are also draught proofed to further improve energy efficiency.

If your windows do not need replacing, we also offer a separate draught proofing service for timber sash windows and casement windows in London, aimed to help improve the thermal efficiency by stopping draughts from coming through gaps arounds your windows.
