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
  • We just wanted to say what great guys you all are, and what a good job you have done. We are exceedingly happy with the work you have done for us, and will definitely spread the word.
    — Mr and Mrs Carter, London & Cambridge

    — Franscesco Fullin, Norwich
  • Sash Window Preservation were very professional throughout from the initial survey to carrying out the work. We were so surprised that so little disruption was caused and were delighted that the windows could be repaired as feared replacement. The fact we were given a fixed priced was a real bonus as we knew exactly how much the work would cost us. All in all we can thoroughly recommend Sash Window Preservation.
    — Mr Coe, Wymondham
  • Please can you pass on my sincere thanks to all the team, the windows are just amazing and have made such a difference. I will be in touch next year to replace some more.
    — Tracey Baverstock, Thetford
  • Very good service with polite and efficient staff. I had my front sash window done which has shutters and it looks superb and doesn't rattle anymore! I wish I'd known about this company last year when I had all the other windows replaced with UPVC...the only reason they couldn't replace the front window was because of the shutters. The cost was the same.
