  • 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
  • Sash Window Preservation renovated four sash windows. They were punctual, charming, helpful, tidy and finished the job on time for a very competitive price. I would recommend them without reservation.
    — Mr Hyde, Norwich
  • Well after being quoted by another company who failed to turn up for the work, the guys at Sash Window Preservation were quick in getting their quote in and creating time to get the work completed (even working some weekends). The sash windows rattled and were draughty, but now thanks to the guys we have windows to be proud of.
    — Mr & Mrs Rose, Norfolk
  • 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
