If refurbishing your existing timber box sash windows isn’t an option, or you need new sash windows for an extension, we can help.

When you replace old sash windows in a period property, it’s essential to keep the look authentic. Especially if you live in a conservation area or listed building. Our timber box sash windows are the perfect choice. They combine the elegance of traditional sash windows with the added benefits of modern materials. No matter whether your style is Georgian, Edwardian or Victorian, we can match your windows to the period of your home. And sash windows aren’t just for period properties. They can add a traditional touch to a newer home too.

"Many thanks for doing a fantastic job on our bathroom timber box sash windows, I'm absolutely delighted with the work. Thanks also for being so professional – its always a worry letting someone into your home when you have to go out for the day but we could trust you completely.  Thanks again for a great job, I'm sure we will be contacting you again". - Dave
