Traditional. Contemporary. Bespoke.

For an Authentic Enhancement of your Home

For a truly traditional appearance, whether you are looking to restore a period property, replace double glazing or start a new build project, our wooden sash windows not only look elegant and timeless, they also offer energy efficiency, smooth operation and are made to last.

Our sash windows are authentically replicated and full of character. Their performance rivals and surpasses many modern windows. Highly insulating, rattle-free with an easy opening action for peace of mind.

Designed with detailing and carefully selected decorative features such as glazing, bars, mouldings and architectural hardware, our bespoke wooden sash windows will enhance and improve any home aesthetically and practically.

New Richmond Range Windows

Box Sash

Our box sash windows are fitted with traditional weights and pulleys to counter balance the weight of the glazed panels. The weights themselves are concealed within the box frame.


We also manufacture an alternative modern sash window with a spring mechanism, which replaces the need for lead weights. This sash window option allows for a much slimmer frame if desired whilst retaining the authentic design.

Bespoke Casement Windows

Made-to-order in our Suffolk workshop, our casement windows are constructed entirely from high-grade timber. They are masterfully finished, enduring, secure and thermally efficient.

There are many styles of casement windows to suit different properties; at Deben Joinery we provide a full range from small pane Tudor to modern and contemporary flush designs.

As well as this we offer the option of incorporating traditional butt hinges with stays and fasteners to modern friction hinges with multi-point espagnolette lock fasteners.

Bespoke timber casement windows are a very popular choice in the UK and we are experts at recreating and replicating existing designs for homes in conservation areas and listed buildings.

Casement windows are identified by their side hinges and outwards opening.

Trusted timber

All of our windows are made using the finest timber. Both quality and characteristics of material are hugely important to us and to the outcome of the finished window. We use a range of world-class timbers and work with trusted partners of certified timber merchants who supply extremely reliable and responsibly sourced timber. Our preferred timbers include Utile, Douglas Fir, European Oak and Accoya. See our materials.

We can help you through the entire process, be it restoring, upgrading or fitting brand new windows. Whichever option is right for your project or property, all our windows meet thermal, acoustic and security standards.


Over the years, we have developed extensive experience in working with listed buildings and the associated rules, regulations and restrictions. In fact, period-style windows for Listed Buildings are our speciality. Every single window is bespoke and built to the exact required specification for the sympathetic nature of the project.

Finishing touches

We use a preparation and finishing system that protects the integrity of the paint, allows the wood to breathe and guarantees a perfect finish on all of our windows and doors to give you the confidence in their sustainability and durability. Read more about our workshop.
