  • 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.

  • 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
  • Gary and the others were extremely reliable. The job was finished within 2 days (a day quicker than quoted) working late hours to double glaze the windows to my property in Cambridge. When they had to come back for a little adjustment they organised it within hours. We are very pleased with the outcome both in terms of insulation and looks. I would recommend Sash Window Preservation without hesitation.

We were so surprised that so little disruption was caused and were delighted that the windows could be repaired as feared replacement. The fact we were given a fixed priced was a real bonus as we knew exactly how much the work would cost us. All in all we can thoroughly recommend Sash Window Preservation.
