Mariusz and his team at Belgravia replaced all our sash windows, as well as some doors with beautiful and robust perfect replicas of the Victorian originals. They all fit very well, are easy to use and have made the house much warmer. They were installed with minimal disruption by a very pleasant team. Repairs to outside window sills were also done to the highest standard. I recommend them highly.
