Check out the photos of our windows which are fully draught stripped and are double glazed with some energy efficient glass. We can fit new purpose made, double glazed sashes into your existing box frames. With our vast majority of our existing Victorian/Edwardian timbers within box frame windows still are in sound condition. So you will not only save your money, but can replace the complete sash window. You are also helping the environment by keeping as much of the original timbers within your box frame windows as possible. Contact us today to get your free quote or advise.
