Testimonials

  • Thanks a million Chris! I'm impressed that you managed to save and repair the sash window!
    — Dr Best, King's Lynn
  • 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
  • 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
  • The work is fantastic, really glad we decided to do it. Couldn't be happier.
    — Mr Nicholson, Cambridge

    — Mr Atkins, King's Lynn
