Your traditional windows will look the same after our renovation and double glazing but will be energy-efficient as triple-glazed windows.

If you live in a listed property or conservation area, you might be worried about changing your original windows. However, our team of experts have a wealth of experience working on listed properties and conservation area. They can advise you on the best way to proceed with your sash window renovation project.
We can provide a range of window renovation services for listed properties and conservation areas that do not require any permission from the conservation office and comply with current regulations.
You only need to contact the conservation officer and submit a listed building application form if you want to retrofit vacuum double glazing into your original window frames, as this is considered a ‘material change’.
Otherwise, our other timber sash window renovation services, such as draught-proofing and timber frame repairs, do not require any listed building permission as they are ‘like-for-like’ replacements.
We also support our clients with paperwork when they submit the listed building application form for permission to install double glazing. This application is usually supported with examples of completed projects to prove that window style and appearance will not be altered.

There are a few things you can do to make your sash windows more efficient: Install Secondary Glazing or retrofit vacuum double glazing into existing sashes and install draught-proofing to seal any gaps and prevent draughts. You could also get your sash window frames refurbished if they are in a poor state.
The average lifespan of a wooden sash window is around 30-40 years. Of course, this depends on a number of factors such as the quality of the timber, the level of maintenance and the environment in which the window is situated. A well-maintained sash window should last for many decades.
