Testimonials

  • 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

  • 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.
