Timber Windows London
Beautiful, Handcrafted Timber Windows for Every Home
We design and manufacture traditional wooden windows that enhance London homes, preserving the charm and character of heritage properties and bringing a sense of individuality to newer homes. Every window is precision-engineered to deliver modern security, thermal, and day-to-day performance, without compromising on inspired design and craftsmanship.
Heritage Friendly Window Replacements
As a specialist timber window company, we have extensive experience designing traditional timber windows for listed buildings, conservation areas, and period homes across the capital. We craft true replicas of existing heritage timber windows, preserving even the finest details that make the home unique, while helping homeowners navigate building regulations and heritage requirements.
A Truly Bespoke Experience
From our wide range of traditional timber window styles to modern designs centred around unique aesthetic demands or unusual dimensions, every last Ayrton timber window is fully bespoke. We work with homeowners, interior specialists, and architects to craft beautifully proportioned windows that genuinely reflect each client’s vision for their home.
Built For Modern London Living
Ayrton timber windows are handcrafted using traditional joinery techniques and finished with high-performance glazing, advanced sealing, and precision-engineered hardware to ensure decades of superior thermal efficiency, weather resistance, and acoustic performance. We also colour-match to the UK’s most recognisable and trusted brands—Little Greene, Farrow & Ball, Dulux, and more—with all windows factory finished in a controlled environment for a flawless, durable finish.
Sash Windows vs. Casement Windows: Making the right choice for your home
Choosing between sash and casement windows can be a difficult decision; both are viable options for most homes, and when designed and crafted with modern performance expectations in mind, neither has any clear drawbacks. Understanding their functional and aesthetic differences, and how they’ll affect your home’s look and how you’ll use your living spaces, can help you make the right call with confidence.
Sash Windows
Sash windows, with their balanced proportions, symmetry, and refined detailing, are synonymous with traditional architecture and remain key features of Georgian, Victorian, and Edwardian homes. While weighted sash windows remain the first choice for most windows, modern spring-assisted sash windows are an increasingly popular option for window replacements, especially in areas where space is a concern, such as bathrooms, tight-angle bay windows, and dormer windows. Listed building or conservation area homeowners may only upgrade their existing sash windows with modern replacements that preserve their original appearance of ropes and pulleys.
Casement Windows
Casement windows differ from sash windows primarily in how they operate: they swing outward on butt hinges or espagnolette mechanisms, rather than slide vertically. In many parts of London, the choice between casement and sash windows depends less on personal preference and more on the architectural style of the building—even more so when the property is Grade II listed or is located in a conservation area.
It’s also worth noting that casement windows typically sit flush with the facade, while sash windows are set further back into the brickwork. For this reason, window replacements tend to replicate the original configuration, rather than forcing a style that would come across as historically inaccurate or risk damaging the original brickwork.

Making your brand-new window or door is only part of the job. Ensuring that the product is fitted precisely and securely is important. All our fitters are Ayrton employees, and it’s their job to make sure that they get that perfect fit with minimum fuss.
