Matching Period Homes with Our Timber Casement Windows
We’re Sash Windows London, a family-operated business serving London and Surrey. We specialise in heritage timber sash windows that seamlessly integrate into vintage properties, blending classic aesthetics with contemporary energy efficiency.

Preserving the Legacy of Your Home

Period homes are treasured for their unique architectural designs and historical significance.
They showcase a bygone era’s craftsmanship and aesthetics. However, owning such a home comes with its set of challenges when it’s time to replace draughty or worn windows, especially when it’s a listed building.
These properties have strict regulations to ensure their historic character remains intact. Homeowners must navigate the tightrope of maintaining the property’s original appearance while integrating modern updates. This involves a delicate balance between preserving history and addressing present-day needs.

Combining Modernity with Heritage Design
While our primary goal is to replicate the timeless beauty of traditional timber casement windows, we never compromise on delivering state-of-the-art performance. Our windows merge the visual appeal of heritage designs with the best of today’s structural advances, ensuring both aesthetic charm and energy efficiency:
Double Glazing
A significant amount of home heat loss is attributed to windows. With double glazing, we offer a solution that addresses this issue, especially vital for older homes originally fitted with single-pane windows.
Acoustic Insulation
For homes situated in bustling urban settings like London or near busy thoroughfares, our windows’ soundproofing capability can transform your living experience, ensuring a quieter and more peaceful environment.
Guaranteed Durability
Longevity isn’t just a claim; it’s a promise. Our timber components come with a 30-year guarantee, while our paint and installation carry a 10-year assurance.
Enhanced Thermal Insulation
Our combination of double glazing and robust custom frames amplifies thermal insulation, reducing your energy bills and keeping your home pleasant.


Period Appropriate Finishing Touches
Sash Windows London understands the subtleties and intricacies associated with different historical eras.
We offer an expansive range of finishing options, from carefully curated paint shades to authentic stains, each aimed at capturing the essence of a particular architectural period. Whether you’re aiming for the regal Victorian, the romantic Georgian, or any other distinctive style, our finishes will give your window that impeccable touch.
It’s not just the window finish that can capture the essence of a period; the fixtures and fittings play a crucial role too. Classic door knockers, reminiscent of bygone eras, can be the centrepiece of your entrance. Ornate door knobs, monkey tail handles, and the elegant Balmoral swan handles add not just functionality but an authentic historic flair.
Preserving History with Modern Excellence
Our timber casement windows are a seamless blend of time-honoured tradition and modern-day innovation.
When you choose Sash Windows London, you’re not only ensuring the preservation of your home’s historical charm but also investing in long-lasting quality and unmatched performance.
