Testimonials

  • Really impressed with the firm. They closely matched existing sash windows for a new window to my property in Loughton. Would definitely use them again and recommend.
    — Peter MaCallan, Loughton, Essex
  • I am really pleased with the sash windows which were double glazed in my property in Cambridge, and was really impressed with the way you all worked. You were a pleasure to have in my home.
    — Mrs Hemming, Cambridge
  • Thanks a million Chris! I'm impressed that you managed to save and repair the sash window!
    — Dr Best, King's Lynn
  • The work was carried out on time with minimal disruption. We're so glad we chose to have the windows renovated rather than replaced as the character of the house is maintained but with much improved noise and draught insulation.
    — Mrs Bond, Norwich
  • We are very happy with the work the guys from Sash Window Preservation carried out and how have double glazed and draught free windows to our terrace in King's Lynn. We found them to be professional and hard working.
