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.

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.

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.
