Testimonials

  • They nursed me through the planning process (grade II listed) and despite them being in Norfolk and me in West Devon, sent a team of 7 who worked incredibly hard and left no mess, who completed the task of four sash and two modern windows, in one day. I can't recommend them highly enough. But perhaps increased warmth and much reduced external noise is recommendation enough.
    — Mrs Susan Hall, Devon
  • We are very happy with the works, it's great to have the windows working. James worked hard, was professional and pleasant to have around and it was great that the job came in cheaper than anticipated as were able to keep a bottom sash and one sill without replacement.
    — Anna & Francis, North Norfolk
  • Your chaps were cheerful, upbeat and quick, they turned up when they said they would and were quick and efficient and did a good tidy job. House was left locked up and clean. Messages were communicated and were pleasant and polite at all times. And one more thing I slept till 10:30am on Saturday morning.....no noise!
    — Mrs Knights, Cambridge
  • We are absolutely delighted with the door, it's a wonderful piece of craftsmanship and I can't stop admiring it! Such care and attention to detail is a rare thing these days.
    — Kate West, Norwich
  • 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.
    — Jane Le-Surd, Diss
  • The work is fantastic, really glad we decided to do it. Couldn't be happier.
    — Mr Nicholson, Cambridge
