Testimonials

  • I am really pleased with the sash windows which were double glazed in my property in Cambridge, and was really impressed with the way you all worked. You were a pleasure to have in my home.
    — Mrs Hemming, Cambridge
  • The remade sashes are beautiful, with the division bars as fine as I could have wished and the slim double glazing units quote inconspicuous. I was so impressed by the work done by the carpentry and fitting team.
    — Mrs Hannaford, Norwich
  • We were actually considering replacing our sash windows when we met with Gary to discuss renovation. They were able to offer exactly what we wanted - replacing the glass in the sash frames with double glazed units. The wood and sills were repaired and the windows really do look and work great again. We are so glad we decided to keep them. Gary and his team were really helpful and informative and got the work done very quickly. Thanks!
    — Mrs Saunders, Cottenham, Cambridgeshire
