Testimonials

  • Thanks a million Chris! I'm impressed that you managed to save and repair the sash window!
    — Dr Best, King's Lynn
  • Great Service. Excellent job. Super friendly. No more draughts. The fitters were great. Helpful, polite, friendly, clean and tidy. We have a lot more work to come so we will stay in touch.
    — Paul and Michelle Mersh, Colchester
  • We were keen to reuse our existing frames if possible, and in two out of three sash windows that proved to be the case. Grouting out in situ is a messy business, even done out on a patio, but Jerome and Paul were excellent and expert carpenter-joiners, and took the utmost care to protect the environment from dirt and dust, cleared up assiduously and kept up a cheerful banter throughout the job. It was a pleasure to host them, and now we have a cosy home with smoooothly gliding sashes.
    — Martin Nelson, London
  • The remade sashes are beautiful, with the division bars as fine as I could have wished and the slim double glazing units quote inconspicuous. I was so impressed by the work done by the carpentry and fitting team.
    — Mrs Hannaford, Norwich
  • Thank you and the team for your excellent work. We are extremely pleased.
    — Keith, Attleborough
  • 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.
