Testimonials

  • 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
  • Thank you for the work that you carried out on our sash windows at 45 Tenterleas, St ives. We are really impressed with the renovation of the original sliding sash window, and the clean state that everything was left in (despite the awful weather!)
    — Anthony Challinor, St Ives
  • 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.
