Testimonials

  • 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
  • We are extremely happy with the work carried out by Sash Window Preservation, from the initial quote to the restoration work and the draft proofing. All work was done to an extremely high standard and special attention was paid to our original stained glass windows. The staff we dealt with in the office and when carrying out the works were very helpful. I would definitely recommend Sash Window Preservation and am very happy with the work carried out, and looking forward to a warmer winter!
    — Amy Horton, Norwich
  • 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
  • It's always such a pleasure when a company exceeds your already high expectations. From the initial site survey to works completion (I should mention I am a professional project manager) they did a marvellous job and my client was thrilled.

  • 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.
