Testimonials

  • Very impressed with the service from Sash Window Preservation. Staff dealing with the quote were very helpful and professional nothing was too much trouble even when I changed the requirements. The work was completed on time to a very good standard and the refurbished sash windows have really improved the overall appearance of my Cambridge house. The windows are no longer draughty and the house is quieter - now looking forward to cheaper heating bills

  • Many thanks for doing such a great job on our windows, we'll be sure to recommend you.
    — Mr McGee, Huntingdon
  • 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.
    — Sandra Schmidt, Cambridge
  • 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
  • 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
