BESPOKE Timber Sash Windows
MAKE A GRAND IMPACT WITH Traditional & Contemporary Wooden Sash Windows in Surrey
Sash windows are a defining feature of many Georgian and Victorian properties across Surrey and London. Our timber sash windows are designed to replicate traditional proportions and slim sightlines, helping to retain the character and elegance of period homes.
With modern glazing and high-quality draught excluders, they also help improve thermal performance, reduce heat loss and increase comfort throughout the year. Precise manufacturing ensures each window is weather-tight, secure and smooth to operate, giving you traditional style with reliable everyday performance.
Wooden Sliding Sash Windows
We manufacture traditional box sash windows with weights and cords, as well as spring-balanced sash windows that allow for a slimmer frame profile. Both options are designed for smooth operation, long-term reliability and an authentic timber finish.
Made using engineered timber and modern manufacturing techniques, our sash windows are built to reduce the risk of warping or twisting over time. This helps maintain their appearance, performance and ease of use for many years.
We can also match original design details, including external sash horn profiles and, where required, internal sash horns. Whether you need supply only or a full installation service, our expert team can guide you towards the right solution for your home.
Benefits of Installing Wooden Sash Windows
Replacement timber sash windows can enhance both the appearance and performance of your home. Key benefits include:
Double Glazed Sash Windows
Retrofitting double glazing into existing sash windows is often a compromise and may not provide a reliable long-term solution. Our replacement timber sash windows are specifically designed to accommodate double-glazed units, helping to improve thermal performance, reduce heat loss and increase energy efficiency.
This means your home can benefit from the charm of traditional sash windows while gaining the comfort, security and insulation expected from modern glazing.
TRADITIONAL BOX Sash Windows
Our traditional timber box sash windows are carefully crafted to replicate the operation and appearance of original period windows. Using weights and pulleys to counterbalance the glazed sections, they offer smooth, authentic movement while preserving the classic sash window design.
In most homes, the majority of the sash box is hidden behind the external brickwork, while internal timber architraves create a refined finish that complements the property’s character.
In some properties, the sash box is fully exposed. In these cases, we can incorporate both external and internal architraves to create a seamless balance of function, durability and period-accurate detail. Our experienced team will guide you towards the most suitable approach for your home.
SPRING BALANCED Sash Windows
Our spring-balanced wooden sash windows combine traditional elegance with modern innovation. By removing the need for lead weights, they allow for a slimmer frame while retaining the visual character and smooth operation of a traditional timber sash window.
They are ideal for extensions, new builds or areas where space is limited, offering greater flexibility without compromising on style. Each window is made to measure, helping you achieve the timeless appearance of classic sash windows with the benefits of modern performance.
