Customer Reviews

August 2019 – Mrs Suluga Fagalib – Darlington, County Durham

To all at Chatsworth Windows, We just wanted to say a big thank you to you all. We are over the moon with our new windows and doors. From start to finish our experience with Chatsworth has been nothing less than outstanding. Simon could not have been more informative or helpful in the process of deciding what we wanted. Each and every person that I have spoken to in the office has been friendly and extremely helpful. The fitters could not be faulted and battled through bad weather to make sure our windows and doors were fitted to an impeccable standard. They look fantastic, thank you.

D & J. Walker

We just wanted to thank you for an excellent job of our conservatory. From the initial advice on size and design through to the installation itself, we were delighted with the service we received from your staff.
