Sash Windows
in Southwark, Lewisham and South London

Known for a traditional style that makes them ideal for heritage homes, sliding sash windows in timber boast period charm and open vertically for a breathable atmosphere. They’re great for new builds as well as rustic homes, meeting the current standards for acoustics, security and thermal efficiency. At Brockley Glass Ltd, we craft these windows by hand and provide decorative workmanship to fulfil your needs. Our team uses the finest redwood pine to build box frames and sashes from scratch, ensuring the best results for Southwark, Lewisham and South London properties.

We can remove your existing glass and reglaze the window as needed, or create new installations as part of a window replacement service. Our experts apply cutting-edge techniques to match a certain style but can also provide unique detailing based on your preferences.

At Brockley Glass Ltd, we understand that timber sash windows must often meet exact criteria, especially in conservation areas. For this reason, we can supply drawings to aid with planning applications and offer friendly advice to make sure horns and glazing bars are correct.

Sash Windows | A Blend of Modern Quality and Period Allure

Popular throughout the centuries, sashes are made of high-quality timber or innovative UPVC. While traditional windows feature cords and weights, you can also a spiral balance. In either case, our team will implement the latest advancements while reproducing a product of old-school charm.

A Range of Window Styles Available

Known for their ‘six over six’ design, Georgian sash windows used astragal bars due to the limitations of the time. These days, these bars are purely decorative. Alternatively, you could go for Victorian windows with a ‘two by two’ panel style. These increase the flow of light with larger glazing and use sash horns within the design. Finally, you could select Edwardian windows with a ‘six over two’ appearance to replicate a popular style from the start of the twentieth century.

Based in Brockley, our team can fully customise sash windows to your home or heritage property in Lewisham, Southwark or the nearby areas. We make them bespoke to your window size and can either fully install them or deliver them to your location.


The Benefits of a Sash Window

Sash windows achieve a charming aesthetic that makes them perfect for period housing but, in UPVC, they are also highly convenient. UPVC windows can tilt for easier cleaning from the inside and have a finish in any colour you choose. Please note that timber sash windows do not tilt but come with draught-proofing and a choice of ironmongery. Brockley Glass understands that you don’t have time to maintain your windows on a regular basis. Thankfully, technology has come a long way, so you won’t have to worry about peeling, rotting or blistering.

Whether you choose uPVC or handmade timber, you can expect a stunning window built to the measurements needed and your specifications.

Visit our testimonials to see why we’re still the preferred choice for sash windows, even after 50 years in the business. We build sashes individually as well as in pairs, and can reglaze your windows either at our workshop or on-site for your convenience.
