London’s Finest Accoya Sash Windows
At Todi & Boys, we have proudly specialised in crafting traditional timber windows and doors using the highest-grade Accoya wood for years. We have a dedication to quality, and our team has spent tens of thousands of hours perfecting and installing the most exceptional Accoya sash windows London has to offer.
Our luxurious double-glazed Accoya sash windows not only provide superior insulation to keep the chill at bay on even the coldest nights – but also elevate any home with the timeless charm of Edwardian, Georgian, and Victorian sash designs. These windows are not just beautiful, they’re also remarkably energy-efficient, offering year-round comfort and helping to reduce energy bills.
From compact to classical, straightforward to intricate, and everything in between, we’ve seen and mastered it all. With Todi & Boys, even the most unique or challenging like-for-like Accoya replacements are handled with unrivaled craftsmanship, ensuring every window is a perfect blend of beauty and performance.
The Benefits of Accoya Sash Windows
Accoya sash windows offer several significant advantages over other types of wood used for sash windows, especially for homes in London.
- Superior Durability & Resistance to Weathering: Accoya undergoes a unique acetylation process, making it highly resistant to rot, decay, and insect damage. This makes it particularly suitable for London’s varied and often wet climate
- Longer Lifespan: Accoya windows last 50+ years above ground, outperforming standard hardwoods – even in harsh conditions. Factory spray-painted, they last significantly longer than traditional timber – cutting maintenance costs, plus, skipping paint won’t void the rot guarantee. Ideal for hard-to-reach areas like upper floors, Accoya offers a long-lasting, low-maintenance solution.
- Enhanced Thermal Insulation: Accoya wood’s thermal properties are improved due to its dense structure. Combined with double glazing, it offers superior insulation, which is crucial for energy efficiency in London homes.
- Environmental Sustainability: Accoya is made from sustainably sourced wood, and its production process is eco-friendly. It has a very low environmental impact and a long lifespan, which reduces the frequency of replacement windows.
Timeless Beauty and Superior Aesthetics
Accoya sash windows offer a perfect blend of traditional beauty and modern performance, making them a standout feature in any home. With their smooth texture and fine, consistent grain, Accoya wood provides a flawless finish that enhances the natural elegance of your windows.
Our London sash windows are incredibly versatile, effortlessly complementing a wide range of architectural styles – from period properties in London’s conservation areas to sleek, modern interiors. Their ability to take paint beautifully means you can customise the finish to suit your home’s design, whether you prefer bold colours or more subtle, natural tones.
Not only do Accoya sash windows maintain their visual appeal over time, but they also resist weathering, warping, and shrinking, keeping their crisp, clean lines intact for decades. This makes them the ideal choice for homeowners looking for windows that combine lasting beauty with minimal upkeep. With their exceptional stability and classic charm, Accoya sash windows truly offer the best of both worlds – timeless aesthetics and modern durability.

Jon Chan, Camden
Albi and team were very helpful and efficient, accommodation some changes and making helpful suggestions during the initial requirements gathering phase. Finished product is excellent after an efficient install. The shutter company we subsequently used said they’d never seen such perfect sash windows. See More.
Ceeri Heasman, Putney
Following a recommendation from a neighbour we used Todi & Boys to replace all our old sliding sash windows with double-glazed versions of the same. Price quote was lower than other companies we’d had to quote, work was carried out quickly & efficiently & there was very minimal damage to the interior (something I was worried about). Have already recommended to friends & looking forward to a cosy Winter with our draft-free new windows! See More.
Mike Sims, Clapham
Todi and Boys have over the last few years, installed six double glazed sash windows for us. Our expectations are high and the company have exceeded what we hoped for, with quality, service and workmanship in every single window. So when we needed a new front door and frame, Todi and Boys were our first choice. Having just completed the work on the new door, we are absolutely thrilled with it both with the quality and finish which are superb.. From start to finish, the care and attention has been amazing, even the invite to view their factory and to select the right colour for the door. Todi and boys are a family run business and the whole team go the extra mile to give you the service . quality and workmanship that many other companies do not provide. We have no hesitation in highly recommending them for anyone needing new doors or windows. See More.
Libby Grant, Chelsea
I am absolutely in love with our new door and beautiful new timber sash windows. The service was fantastic from start to finish and we couldn’t be happier with the outcome. Would not hesitate to use Todi again and couldn’t recommend more highly. See More.

I recently had the sash windows in three rooms replaced by Todi and Boys having seen their van in the area and looked at their website. Their workmanship was excellent both in production and fitting. They did the work on time and made sure everything was clean afterwards. The sash windows look great and I would definitely recommend them. See More.

Todi & Boys recently replaced two of our sliding sash windows. The quality of the product is excellent, installation was quick & efficient, and the customer service support was friendly, efficient and exceeded our expectations. A particular call-out to Ada and Shab who were very helpful throughout. See More.

Todi & Boys provided box sash windows within 6 weeks of my uprated specification for the bay window. The increased specification included differential widths of glazing, laminating, providing an acoustically superior barrier as well as a beautiful looking hardwood sash window. See More.
Kate Gibson, Twickenham
Over the years, I have had Todi & boys replace all the sash windows and casement windows in my house including the front bay, and my French doors onto the garden.

Todi and boys recently arranged and installed two double glazed sash windows in our Victorian terraced house. Extremely happy with both the quality of the windows themselves as well as the professionalism and general attitude of the workmen that came to fit them. Service has been fantastic throughout the process and would definitely use them again. See More.
Jane Jones, London
I cannot recommend Todi and Boys highly enough. We are delighted with the quality of our new replacement sash window (the second we have had from the team) and are particularly grateful that the window was replaced at a very busy time before Christmas – fitting in with our plans. Ada and the team are most professional and friendly and we will definitely be using them again! See More.
Chris Haworth, Putney
We had a very good experience with Todi and Boys from start to finish. The end product of our box sash windows is excellent and the customer service & after sales care has been similarly so too. Well recommended. See More.
Camilla Orr, Clapham
Having just had most of our sash windows replaced by them, we couldn’t recommend T&B more highly. The quality of the workmanship is excellent, and the whole process is managed extremely professionally and efficiently. Any questions or small issues were dealt with quickly by Shay. Given the quality and detail, we also found the quote to be competitive. See More.
Hereward Walker, Fulham
Had 5 bespoke double glazed wooden sash windows made and installed by todin and boys. Service from start to finish excellent. Quality and price of product good and the team who installed left the house immaculate. Highly recommend. See More.
Rosie Doggett, London
Our Victorian terraced house in Battersea contained the original Victorian sash windows which were draughty, painted shut in places and had been repaired many times. Most importantly we were being woken each morning at 4.30 by the first ‘plane of the day as the old windows had little decent sound-proofing. We obtained 3 quotes for our wooden Victorian-style double-glazed spray-painted sash windows and found the Todi and Boys proposal to be reasonably priced and of the best technical specification. We visited their workshop in Putney and we were impressed by the quality of their workmanship. See More.
