Timber Window and Door Specialists
High Quality, Traditional Windows and Doors
Established in 1994, The Sash Window Workshop has 30 years experience specialising in manufacturing and installing traditional wooden windows and doors, which are designed to complement your period home while improving energy efficiency.
We offer a supply and installation service and a draught proofing service in London and the South of England, with a supply only service for new joinery across Great Britain.
We are a multi-award-winning company and understand the importance of providing a high quality product and service, reflected by the fact that over half our orders come from previous customers or recommendations. We are also proud to be a Which? Trusted Trader.
Beautiful wooden window and doors
Are your windows or doors rotten or letting in the cold weather, resulting in high heating costs? Operating out of our factories in Berkshire, we manufacture and install energy efficient new sash windows, wooden casement windows, external French doors, timber Front doors, Stable doors, Sliding doors and Bi-fold doors.
We also supply and install secondary glazing and new sashes into existing frames (replacing just the moving parts) for timber windows. Our repair services comprise draught sealing and minor repairs.
The majority of our replacement wooden windows and doors are double glazed. However, we can also manufacture single glazed windows and doors, or use our heritage glazing, where standard double glazing is unlikely to be approved (listed buildings and some conservation areas).
We use a timber called Accoya, as standard, which is highly durable and stable. Accoya is a sustainably sourced timber which comes with a 50 year anti-rot guarantee.
All our new windows and doors come fully factory finished and are draught proofed to further improve the soundproofing of the windows and improve the energy efficiency.
Our beautiful new wooden box sash windows and bay sash windows are manufactured at our workshop in Berkshire by our experienced team of tradesmen.
They are designed to improve energy efficiency, while retaining the character and charm of your period home, and come with extensive guarantees. We offer an installation service across London and Southern England.
We have extensive experience manufacturing and installing timber casement windows in period properties.
Our high quality, replacement timber casement windows are designed to be energy efficient, while retaining the traditional charm and character of your home.
EXTERNAL TIMBER DOORS
Designed to be in keeping with your home, our external wooden doors are made to order by our craftsmen to individual designs, agreed with you before manufacture.
When required, we can exactly match the detail of any existing bi-fold door, French door, back door or timber front door.

“This is the third time we have had windows replaced by The Sash Window Workshop, in 2 different properties and over a period of about 15 years. We have always marvelled at how beautiful the workmanship is and how efficiently the service works.“
