Timber Windows and Doors: London

Manufacturing, Installing and Repairing Timber Windows and Doors in London

The Sash Window Workshop replaces and repairs timber windows and doors across London. Established in 1994, we are period property and conservation area specialists.

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

All our windows are manufactured in our UK workshop by our skilled craftsmen who utilise the latest technology to make high quality, timber windows to suit your home.  Our timber sash windows and casement windows come fully factory finished.  They are double glazed as standard and are draught proofed by our fitting team on installation to help improve energy efficiency.

If you are unable to have standard double glazing due to planning restrictions, we can also manufacture single glazed windows or install our heritage double glazing.

Accoya Timber: 50 Years Anti-Rot Guarantee

For new sash windows and casement windows we recommend using a timber called AccoyaTM.

AccoyaTM is a sustainably sourced modified wood which is highly durable and comes with a 50 year anti-rot guarantee.  The high durability means that it doesn't require as much maintenance as some other timbers.
