Replacement Timber Windows in Kingston upon Thames
Traditional Timber Windows in Kingston Upon Thames
The Sash Window Workshop has been replacing timber windows in the Royal Borough of Kingston upon Thames since 1994 and are a multi-award-winning manufacturer and installer of traditional timber windows.
We have extensive experience working in conservation areas across Kingston upon Thames and can comply to listed building requirements, where necessary.
Traditional timber windows and doors were not manufactured to consistent standards as they are today. Consequently, every window that 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.


Manufacturing Wooden Windows
All our windows are manufactured in our workshop in Berkshire by our skilled craftsmen who utilise the latest technology to make high quality, timber windows to suit your home.
Our 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.
Excellent Customer Service

We are proud to have been Which? Trusted Traders since 2014 and have a 5 star Trustpilot rating. We have also won Which? Trader of the Month Award twice, as well as having won an award for our work to reduce our carbon footprint and achieving Carbon Neutral Plus status.
We offer a range of services including secondary glazing, installing new sashes into existing frames (replacing just the moving parts), draught sealing and replacement windows and doors. We offer various new joinery products including complete new sash windows, casement windows, French doors, Front doors, Sliding doors and Bi-fold doors.
Accoya Timber: 50 Years Anti-Rot Guarantee
For new sash windows and casement windows we recommend using a timber called Accoya.
Accoya is a sustainably sourced modified wood. The timber is highly durable, stable, and comes with a 50 year anti-rot guarantee.
The high durability and stability of the timber means that it is long lasting and that it doesn’t require as much maintenance as some other timbers.
It also looks attractive when coated in a wide range of finishes, allowing for high quality, beautiful timber windows.
