Like-for-like Victorian Sash Window Replacements

Victorian Sash Windows date back to the 1800s, and like anything, over time, they become worn and start failing to do the ever-important job of keeping your home warm and draught-proofed. But don’t worry! We can provide exact replicas of your current Victorian window.

If your wooden Victorian sash windows have become stiff and hard to operate. This is due to the layers of thick oil based paint layered on the wood over the years, making them stiff when opening or leaving them completely shut. Certain types of wood also swell naturally during the rainy seasons after being exposed to the harsh London weather.

Replacing them with our sturdy, handcrafted Victorian sash windows, made from premium quality materials and the finest joinery processes, means that you can have beautiful and elegant wooden sash windows that work perfectly in your home.

When considering the replacement of Victorian sash windows within a conservation area, it’s paramount to acquaint yourself with the area-specific guidelines and engage in early consultations with local planning authorities. A risk at this stage is the denial of your application, as this can cause significant setbacks.

By enlisting the expertise of seasoned professionals like Todi & Boys, we guarantee that your design seamlessly aligns with all preservation mandates and potential energy requirements. Should you require assistance, our team can provide guidance in submitting your application, mitigating any risks of rejection.

The regulations for Victorian sash window replacements are often influenced by the specific area you live in. In areas surrounding Central London, it’s common for replacements to adhere strictly to like-for-like specifications concerning styling, design, and materials. Regulations may also mandate single glazing and specific glass thickness to preserve the historical character of buildings.

However, it’s possible that your area offers some flexibility regarding window style, glazing options, materials, and glass thickness. This is dictated by the conservation level in place. Our expertise at Todi & Boys allows us to assist you in navigating these nuances, ensuring you find precisely what you seek while adhering to conservation guidelines.

All of our wooden Victorian sash windows come with extensive warranties which are determined by your choice of timber, and where necessary, the level of maintenance required. If anything isn’t working exactly as it should for your new Victorian windows, our team will be there to fix it as quickly as possible.

Todi takes huge pride in the quality of our products and works hard to ensure all of our customers are left with a smile on their face.

If you’re currently searching for your dream sash windows, you might be surprised by the range in prices quoted by various sash window companies. This can often cause confusion – after all, you want to be absolutely certain you’re making the right choice. Here are several factors that influence the cost of sash windows:

Just like when purchasing a house or a new car, a number of factors can drive up the costs. To ensure you’re making the perfect decision, it’s crucial to select the perfect partner who can deliver exactly what you’re looking for. At Todi & Boys, we provide personalised guidance to all our customers, assisting you through every aspect mentioned above.

We are more than happy for our customers to come and visit us in our workshop to find out everything they need to make the most informed decision possible.

Victorian windows either have two clear panes of glass, or four panes of glass that are separated by a thin wooden strip running from the top to the bottom of the glass.

This is due to the Victorians being able to produce larger individual panels of glass, unlike Georgian sash windows, which use smaller panes of glass.

The traditional Victorian window frames are made out of timber and come in a variety of designs, including curved or straight sections. The glass used is usually bevelled or patterned, depending on the desired look.

Victorian sash windows either have two clear panes of glass, or four panes that are separated by a wooden strip. The frames are generally narrower than Edwardian windows.

Edwardian sash windows often have multiple panes of glass, split by wooden strips on the top sash, and one large pane of glass on the bottom one.

Georgian sash windows are often large and detailed, featuring 6 or more small panes of glass, put together in a symmetrical pattern and held together by wooden strips. They are usually the most ornate of all three styles.

Each window has its own unique features, but all three sash windows. The choice between these window types often comes down to personal preference and house design, as each type has its own set of benefits.

Beyond stunning looks from the inside and out of your home, new Victorian windows will be much easier to use than your old ones, which may have become stiff and hard to operate.

They will also provide other benefits such as higher levels of security, noise reduction and draught proofing.

Yes, investing in new Victorian windows can significantly enhance the energy efficiency of your home. Modern Victorian-style windows often come with advanced features such as double glazing, superior insulation materials, and improved sealing mechanisms compared to their traditional counterparts. These upgrades help minimise heat loss during the winter months and prevent heat gain during the summer, resulting in reduced energy consumption for heating and cooling.

Additionally, many new Victorian windows are designed to meet or exceed energy efficiency standards, providing you with not only a more comfortable living environment but also savings on your energy bills over time.

If possible, we always recommend Accoya. While it may have a higher initial cost, it promises a better return on investment over the lifespan of your Victorian windows.

With Accoya, you eliminate concerns about rot and ongoing maintenance like painting, all while prioritising environmental sustainability.

However, we understand your familiarity with your home’s needs, so if you prefer a combination of Accoya and a hardwood based on the areas of your home that face the highest impact from the weather – that’s entirely possible.

We excel in working various different types of wood and can accommodate your preferences accordingly. Explore further details on the best wood choices here.

Once your windows have been designed and manufactured, we agree on a date to install your windows. If you have an ongoing renovation, we are happy to split specific window fittings across several days based on your needs. Our team will leave your home exactly how they found it, and if there is anything you are unhappy with, we will be back to ensure everything is perfect.

Victorian sash windows require regular upkeep to keep them looking their best and operating smoothly. This includes cleaning 4 times a year as standard and painting every 4-6 years for standard windows, and 8-10 years on our Accoya windows.

For older windows, periodically checking the frames for signs of rot or decay is also important. Where possible, repairs should be carried out as soon as they are noticed to prevent further damage.


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.

Our Google Reviews

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.
