To ensure your sash windows complement your home’s exterior decor, we offer custom paint colours and finishes. Whether you want a heritage colour palette, a modern bold shade, or a specialised finish like high-gloss or matte, we can create the perfect look for your windows.

Traditional Joinery with Modern Security

If you want the traditional look of sash windows combined with modern security features, we offer bespoke designs with multi-point locking mechanisms, reinforced frames, and laminated safety glass. This ensures both aesthetic appeal and enhanced home security.

Custom Wood Species

For a truly unique touch, we offer sash windows made from specific types of wood such as Pine, Meranti, Oak, Accoya or other high-quality timbers. This allows your windows to match your interior woodwork and provide a luxurious finish to your South London home.

Double-Glazed Retrofit for Existing Frames

More than just a pretty pane!

How sash windows, an iconic feature of British heritage, are proven by Cambridge researchers to be key in efficient home ventilation.

Sash windows are not just a beautiful architectural feature of Great Britain; they also play a crucial role in home ventilation, as described by Cambridge researchers. These windows, with their distinctive vertical sliding panes, contribute significantly to natural ventilation, which can reduce the energy required for heating and cooling homes.

Researchers at the University of Cambridge have studied how sash windows facilitate effective ventilation. Their findings show that when properly used, sash windows help remove pollutants and excess heat from indoor spaces. By leveraging temperature differences between indoor and outdoor environments, sash windows allow warmer indoor air to rise and escape through the top, while cooler outdoor air enters through the bottom.

By integrating these findings into smart building designs, sash windows can automatically adjust to provide optimal ventilation, reducing the reliance on artificial cooling and heating systems. This contributes to energy savings and promotes a sustainable environment, showcasing the functional elegance of this traditional British window design.

For more information, you can refer to the studies by the University of Cambridge's Department of Engineering​.

Sash Windows in South London
Wooden Double-Glazed Sash Windows

We’ve got you covered!

Meeting all your sash window needs, from historic to contemporary styles, ensuring quality and satisfaction.

Single-Hung Sash Windows
If you own a Georgian or early Victorian property, you might have single-hung sash windows. These windows feature a simpler mechanism, with only the bottom sash being operational. This design provides good ventilation from the lower half. We can replace your single-hung windows with new wooden or uPVC frames. If desired, we can also upgrade them to double-hung sash windows for enhanced functionality and ventilation.

Double-Hung Sash Windows
If your home is from the Victorian or Edwardian era, it might feature double-hung sash windows, where both the top and bottom sashes can move. This design offers excellent ventilation, allowing warm air to escape from the top while cool air enters from the bottom. We can supply and fit new double-hung sash windows in either wooden or uPVC frames, maintaining the classic look while improving functionality and energy efficiency.

Box Sash Windows
Box sash windows, commonly seen in Georgian and Victorian homes, feature a traditional design with counterweights hidden within the frame. This mechanism ensures smooth and balanced operation. If you need to replace your box sash windows, we provide high-quality wooden or uPVC frames, maintaining the period look while enhancing durability and ease of use.

Spring-Balanced Sash Windows
For a more modern approach to sash windows, consider spring-balanced sash windows. These use a spring mechanism rather than the traditional weight and pulley system, making them easier to install and maintain. Ideal for contemporary refurbishments, we can fit these windows in wooden or uPVC frames, blending traditional aesthetics with modern convenience.

Arched Sash Windows
Arched sash windows, often found in high-status Georgian and Victorian buildings, feature a distinctive curved top sash that adds elegance to any property. If your home includes these architectural details, we can custom-make arched sash windows in wooden or uPVC frames, ensuring a perfect fit and preserving the unique charm of your property.

When tradition meets innovation

Bringing classic style and modern efficiency to South London homes with double-glazed uPVC sash windows.

Our uPVC sash windows blend the timeless charm of traditional designs with the modern benefits of uPVC, making them a perfect choice for both new builds and period property renovations.

Unlike traditional timber, uPVC doesn’t rot, warp, or require regular painting, making it ideal for the British climate. Our uPVC sash windows are designed to withstand the elements while maintaining their functionality and appearance for many years.

In South London, where preserving the architectural integrity of homes is crucial, our windows offer the perfect balance of tradition and modernity. They replicate the look of original timber sash windows, complete with authentic features like sash horns and slim profiles, ensuring they fit seamlessly with the historic aesthetics of many local properties.

With a wide range of colours and finishes available, our uPVC sash windows can be customised to match any style, providing a versatile and attractive option for South London residences. Whether you are looking to preserve the character of a Victorian terrace or upgrade a modern home, we at Bespoke RG are here to deliver windows that combine heritage aesthetics with contemporary performance.
