Testimonials

  • Thanks for all the hard work in double glazing my sash windows, most noticeable in the kids room where we don't have water running down the window any more!
    — Mrs Massie, Saffron Walden
  • We were keen to reuse our existing frames if possible, and in two out of three sash windows that proved to be the case. Grouting out in situ is a messy business, even done out on a patio, but Jerome and Paul were excellent and expert carpenter-joiners, and took the utmost care to protect the environment from dirt and dust, cleared up assiduously and kept up a cheerful banter throughout the job. It was a pleasure to host them, and now we have a cosy home with smoooothly gliding sashes.
    — Martin Nelson, London
  • Thanks very much for doing the work and repairs, it's nice to have fully functioning sash windows.
    — Mr Lugton, Mundesley
  • Just wanted to say thank you both so much for coming over to do the window yesterday, it was REALLY kind given how busy you are to fit me in and much appreciated. I can't imagine how we put up with it like that for nearly 20 years!
    — Mrs Georgina Gurney, Northrepps
  • Thank you for the work that you carried out on our sash windows at 45 Tenterleas, St ives. We are really impressed with the renovation of the original sliding sash window, and the clean state that everything was left in (despite the awful weather!)
    — Anthony Challinor, St Ives
  • The lads that came over were super. They did a great job and were really polite and tidied up after themselves. Very impressed with your service!
    — Mr Newcombe, Beccles
