Testimonials

  • This company were very reasonable in price compared to other companies that we got a quote from. They were very professional and arrived on time when they said they would, something rare in tradesmen! We were very pleased with the work they did for us and have gone from having rickety windows to ones that are draught free, easy to put up and down but still retaining the character of our lovely old windows.
    — Mrs Matthews, Norwich
  • 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!
