Testimonials

  • We are very pleased with the refurbishment of our windows at Thurlow House, and the works carried out by Gary and the team.
    — Mr Hall, Badwell Ash, Suffolk
  • Very good service with polite and efficient staff. I had my front sash window done which has shutters and it looks superb and doesn't rattle anymore! I wish I'd known about this company last year when I had all the other windows replaced with UPVC...the only reason they couldn't replace the front window was because of the shutters. The cost was the same.
    — Jane Le-Surd, Diss
  • We would like to say a big thank you to all the team that worked on our home - particularly Chris who was there almost every day. It was instantly quieter after the double glazed units were in and when it's windy the curtains don't move!
    — Mr & Mrs Wood, Great Yarmouth
  • The work is fantastic, really glad we decided to do it. Couldn't be happier.
    — Mr Nicholson, Cambridge
  • Thanks for all the hard work in double glazing my sash windows, most noticeable in the kids room where we don't have water running down the window any more!
    — Mrs Massie, Saffron Walden
  • Many thanks for doing such a great job on our windows, we'll be sure to recommend you.
    — Mr McGee, Huntingdon
