  • 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.
    — Mr Harris, King's Lynn
  • 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.
