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 delighted by the work carried out by Sash Window Preservation Ltd. James and the team were professional and courteous at all times, always keeping me up-to-date with how the job was progressing and leaving the house and drive tidy after each day. I am really pleased with the end result, my original sash windows are now double glazed with no alteration in their appearance, and am now looking forward to a draught free winter.

  • We were delighted to find a company in Norwich who could double glaze our existing windows. When Sash Window Preservation came to do the work we found them to be diligent in their approach to the problem. When finished we found the work had been carried out with great efficiency and time was taken to get everything right. We fully recommend any household that is looking for an alternative to new wooden double glazed windows

  • This company were very reasonable in price compared to other companies that we got a quote from. They were very professional and arrived on time when they said they would, something rare in tradesmen! We were very pleased with the work they did for us and have gone from having rickety windows to ones that are draught free, easy to put up and down but still retaining the character of our lovely old windows.
