Testimonials

  • Thanks very much for doing the work and repairs, it's nice to have fully functioning sash windows.
    — Mr Lugton, Mundesley
  • We're very pleased with the work and the house is considerably less draughty and the slimlite glass looks amazing. Thanks again to the team!
    — Mr & Mrs King, Essex
  • The work was carried out on time with minimal disruption. We're so glad we chose to have the windows renovated rather than replaced as the character of the house is maintained but with much improved noise and draught insulation.
    — Mrs Bond, 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!
    — Mrs Knights, Cambridge
  • It's always such a pleasure when a company exceeds your already high expectations. From the initial site survey to works completion (I should mention I am a professional project manager) they did a marvellous job and my client was thrilled.
    — Louise Negri-Wibberley, Cley
  • Many thanks for all your hard work - the double glazing makes a huge difference you will be glad to hear. Look forward to seeing you back in the New Year.
