The History Of Edwardian Sash Windows

The Edwardian era, spanning from 1901 to 1910, marked a pivotal period of transition in London to a refined elegance in architecture. Edwardian sash windows emerged during this time as a refined evolution of their Victorian predecessors, characterised by their elegant proportions, slender glazing bars, and larger panes of glass.

To this day, their timeless charm and classic design make them a sought-after feature in both historic renovations and modern homes throughout London, serving as a symbol of the city’s rich architectural heritage.


Is It Time To Replace Your Windows?

Like anything, over time, your windows may have become worn and start failing to do the ever important job of keeping your home warm, draught-proof and reducing outside noise.

Perhaps they have become stiff and hard to operate? This often happens due to the buildup of thick oil-based paint layers applied over the years, causing them to stick or even become shut entirely. The wood also naturally swells during the wet seasons after being exposed to the harsh London weather.

By opting to replace your current windows with our quality, handcrafted Edwardian sash windows. You can enjoy the luxury of traditional Edwardian windows that have the benefits of modern window performance.

But you know your home much better than we do, so if you would like some of your new sash windows in Accoya – such as bathrooms, dormers or south facing windows that experience the most weathering, and the rest in a hardwood such as Sapele, we can cater to your needs.

By leveraging the expertise of experienced professionals such as Todi & Boys, we ensure that your design seamlessly adheres to preservation mandates and energy requirements. Our team provides invaluable guidance throughout the application process, minimising the possibility of rejection and ensuring a smooth transition.

The cost is influenced by numerous factors, such as the quality of craftsmanship, quantity required, choice of wood, size, glass style, finishing details, installation expenses, and conservation considerations.

At Todi & Boys, we offer personalised guidance throughout every step of the process. Our team ensures that you receive tailored advice to navigate these factors effectively and make the best choices for your specific requirements.

Edwardian sash windows feature two clear glass panes or four panes separated by a thin wooden strip. The frames, narrower than Victorian sash windows, are made of timber and come in various designs, with coloured glass, stained glass, fancy mouldings and arches. 

Edwardian windows are truly unique in comparison to their Georgian and Victorian counterparts. During the period they surged in popularity, there were huge investments into London’s architecture, so artisans were paid to make all the windows look aesthetic with intricate mouldings, glass, arches and more.

In addition to enhancing the aesthetic appeal of your home, investing in new Edwardian windows brings several practical benefits.

These modern windows offer improved ease of use compared to older models, ensuring smooth operation and effortless maintenance.

They also enhance security, providing increased protection against intruders.

Additionally, new Edwardian windows contribute to noise reduction and draught-reduction, creating a more peaceful indoor environment and an energy-efficient living space.

Upgrading to new Edwardian windows offers a significant boost in energy efficiency. Our modern iterations feature advanced components such as double glazing, superior insulation materials, and enhanced sealing mechanisms. As a result, they effectively minimise heat loss during winter months and prevent heat gain in summer, ensuring a consistently comfortable indoor environment throughout the year.

Furthermore, the improved energy efficiency of new Edwardian windows can lead to savings on energy bills over time, making them a worthwhile investment for homeowners seeking both comfort and cost-effectiveness.

Once your Edwardian windows have been designed and manufactured, we then schedule the installation process. Our team is dedicated to accommodating any ongoing renovations or specific requirements you may have, ensuring minimal disruption to your home environment. During installation, we prioritise achieving a tidy finish, paying close attention to detail and addressing any concerns promptly.

Proper maintenance is vital to preserve the integrity and beauty of your Edwardian sash windows. This includes regular cleaning on a quarterly basis to remove dirt and grime buildup. Additionally, repainting is recommended every 4-6 years for standard windows and every 8-10 years for Accoya frames. This will help to protect against wear and maintain their appearance.

It’s also important to periodically inspect your windows for signs of rot or decay, especially in areas prone to moisture exposure. Promptly addressing any issues that arise will prevent further damage and prolong the lifespan of your Edwardian sash windows. By staying vigilant with maintenance, you can ensure that your windows remain in optimal condition for years to come.


Wood choice 1: Sapele

Sapele is a north African hardwood that’s part of the mahogany family. It looks beautiful and has incredible rot resistance. It takes years for any rot to set in, unlike softwood, which can start to rot in just 1 to 2 years. Read more here.

Wood choice 2: Accoya

Accoya is a softwood that costs more than most expensive hard wood. It doesn’t absorb water in the way other wood does. It doesn’t rot due to the fact rot needs water to develop. Accoya isn’t affected by insect attacks either. Read more here.

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.

Sam Moore, Fulham

Todi and Boys were a pleasure to deal with and were both friendly and professional from start to finish. The new wooden sash window we had installed was fitted incredibly carefully. I would highly recommend them to anyone considering replacing existing sash windows. See More.

KP, Wandsworth

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.

CDH, Putney

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.

Paul Dolan, Wimbledon

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. I can’t recommend them highly enough. They offer good value and provide an extremely professional, efficient service. They’re also, without exception, polite, and friendly and take great pride in the service they give to their customers. See More.

Jane Quayle, Richmond

Todi & Boys window fitters have done a great job fitting my new wooden sash windows. I’m really delighted with the result and their efficient, very pleasant service. See More.

Tony Lafosse, Putney

Really good experience with Todi and Boys. The whole team, Todi, Ada and the installers have been very helpful and considerate. The sash windows seem high quality. I would happily recommend this company for anybody needing sash windows. See More.

Matthew Hepburn, Surrey

I can’t recommend Todi and the boys and girls (Ada) more. They were the most convincing quote for renewed sliding sash windows, bay window and front door. This doesn’t mean cheapest, it means best. Having their own workshop means they design and make all products and this is a big advantage. We were looked after very well by Ada, everything was done on time to the highest quality. Our new front door is superb and the children’s room is now warm! Thank you all! Wishing you continued success! See More.

Gina Wilton, Putney

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.
