Sliding Sash Windows Basingstoke
While Basingstoke is often recognised for its modern development, the town retains deep historic roots. Preserving the character of a period home in Old Basing, Brookvale, or the Fairfields Conservation Area often presents a challenge. Original timber sash windows are synonymous with these Victorian and Edwardian properties, but they are often draughty, prone to rot, and require constant maintenance.
At KJM Group, we specialise in heritage-approved sliding sash windows perfect for Basingstoke’s character homes. Whether you need authentic timber or our virtually indistinguishable Roseview uPVC sash windows—accepted in many conservation areas—we have the solution. We combine classic 19th-century aesthetics with 21st-century A-rated thermal performance to keep your home warm and secure.
As a local, family-run business serving North Hampshire for over 40 years, we offer honest advice and a strict No Pressure Promise. View our full range of Basingstoke Home Improvements here.
Key Product Features
Our sliding sash windows bring timeless elegance to any Basingstoke property, perfectly balancing traditional charm with modern performance. Whether you own a period cottage in Old Basing or a modern family home, we have the perfect solution.
For the ultimate authentic look without the maintenance, we install the award-winning Roseview Collection (uPVC). These windows are virtually indistinguishable from timber and are often approved for use in conservation areas. For purists requiring genuine wood, we partner with George Barnsdale to supply premium, hand-finished timber sash windows designed to last for generations.
Outstanding Performance
Whatever sliding sash windows you choose from KJM, you will get stylish and durable windows. Our sliding sash windows combine a traditional look with modern performance, ensuring excellent weatherproofing and sound insulation. The exceptional insulation means you can benefit from lower energy bills, as you will be less likely to use heating, especially in the winter. Enjoy the benefits of their stunning look without the hassle, as our sliding sash windows have a tilt-back feature for easy cleaning, and there will be no need to repaint.

Astragal Bars & Low E Glass
Astragal bars are an excellent choice because they can fit any product by facing the glass externally. They improve the look of your windows while giving them a traditional Georgian appearance. Intervals on double-glazed sealed units will provide the window with a multi-pane appearance.
Low-E glass reduces heat loss and must be used on energy-rated windows. We use soft-coat glass for our sliding sash windows, which improves light transmission and U-values.

Ultimate Rose Window
The intricate details of the Ultimate Rose windows have been designed to replicate the attractive features of a timber sash window. The gorgeous slim profile and 35mm meeting rail mean no sash windows can compare to the class and quality that Ultimate Rose windows have to offer. The Roseview collection is fantastic at combatting extreme weather conditions, meaning you will have no concerns for rot, cracks, or mould. The sashes are joined vertically, and the frame is joined horizontally. These features add strength and durability, making it a worthwhile product for your Basingstoke home.
