Double Glazed Window Sash Replacements
We fit timber double glazed sashes to your existing box frames. Operating across Surrey and London
Increase the energy efficiency of your home with double glazed window sashes - without the cost of replacing the box frames too.
Original sash windows are beautiful. But because they only have single panes of glass, they aren’t the best when it comes to keeping your home warm.
And, over the years, a build-up of paint on the frames means your windows could have been painted shut or are hard to open and close.
By replacing the sashes with double glazed sashes, combined with our refurbishment service, your windows and home will be transformed.
Warmer home
Quieter
