Bay Sash Window Gallery

We proudly serve all areas of London, specialising in replacement timber bay sash windows. You can find our work in the likes of Wandsworth, Balham, Clapham, Hammersmith, Twickenham, Richmond, Kensington, Putney, Earlsfield, Chelsea, Fulham, Wimbledon, Surrey, amongst many other locations.

When replacing your timber sliding bay sash windows, we recommend choosing Accoya for its exceptional durability and low maintenance requirements. While it may cost more initially, its resistance to rot and environmental sustainability makes it a better overall long-term investment. 

However, we understand that different areas of your home may have different needs. For example, if you want to use Accoya for weather exposed areas like south-facing windows, we can also craft the rest of your windows in hardwoods like Sapele, tailored to your needs and preferences.

Planning permission for wooden sash bay windows largely depends on your location and the specific conservation regulations governing your area. If your home is in a conservation area, you may need to ensure your replacements meet certain design and material guidelines. 

At Todi & Boys, we’re familiar with all local planning rules and can guide you through the application process, ensuring your sash bay windows are fully compliant and reducing the chances of any delays during the initial planning stages. Check out our blog A Guide To Replacing Windows In Conservation Areas. 

Living in a conservation area means adhering to strict guidelines that protect the historical and architectural integrity of your property. Wooden bay sash windows in conservation areas often require like-for-like replacements, focusing on traditional designs, glazing, and materials. 

Some areas of London may allow more flexibility in terms of glass thickness, materials, and glazing options, so it’s important to work with experts who can ensure your new windows comply with conservation regulations – whilst having the exact aesthetics you are looking for. Our team at Todi & Boys can help you navigate these complexities and select the right bay windows for your home.

Yes, we offer extensive warranties for all our bay sash windows. The warranty length depends on your choice of timber and the level of maintenance required. If any issues arise, such as operational problems, we’ll promptly address them. 

At Todi & Boys, we pride ourselves on the quality of our craftsmanship and our owner, Todi, stands behind the quality of our products on every project, ensuring you’re fully satisfied with your new bay windows.

The cost of wooden bay sash windows varies depending on several factors, such as the quality of the materials, size, design features, and whether you’re in a conservation area. 

We offer a range of options, from standard timber bay window sashes to more customised and bespoke designs, all crafted with the utmost care and attention to detail. Our team provides personalised consultations to help you understand the cost implications based on your specific needs and preferences.

 

Bay sash windows are characterised by their elegant design, typically comprising of  three sections—two angled side windows with a larger central window. These windows often feature traditional timber frames with glazing bars, allowing for a combination of clear and decorative glass panes. 

The distinctive shape of sash bay windows creates a beautiful projection from the wall, adding charm and character to both the interior and exterior of your home. They are often found in period properties and can be customised to complement the style of your home.

Bay sash windows differ from traditional flat windows due to their angled or curved design, projecting outward from the wall to create a distinctive bay. The vertical sliding mechanism of the sash windows allows for ease of ventilation and adds to their classic appeal. 

Unlike regular casement bay windows, the sliding sashes in bay windows maintain a traditional aesthetic while offering modern functionality. Their design enhances the interior space, creating a sense of openness and increasing natural light.

Yes, upgrading to new timber bay sash windows can significantly improve your home’s energy efficiency. Modern timber sash bay windows, especially those with double glazing and superior insulation, help reduce heat loss during the winter and prevent heat gain in the summer. This ensures a more consistent indoor temperature year-round.

Additionally, energy-efficient windows can lower your heating and cooling costs, making them a smart investment for long-term comfort and savings.

Our installation process for timber sash windows is straightforward and efficient. Once your bay windows are designed and crafted, we schedule the installation at a time that works best for you. Our dedicated team takes great care to minimise disruption to your home, ensuring the installation is as smooth as possible. We pay attention to every detail, ensuring that your new bay windows are fitted securely, function flawlessly, and meet all your expectations.

Timber sash bay windows require regular maintenance to preserve their beauty and functionality. Cleaning every few months helps remove dirt and debris, and periodic repainting is recommended—every 4-6 years for standard timber and every 8-10 years for Accoya.

It’s also important to inspect the windows for any signs of wear, such as peeling paint, rot, or damage from the elements, particularly in exposed areas like the corners. Prompt maintenance ensures the longevity of your windows, keeping them in excellent condition for years to come.

Materials

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.
