  • 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
  • Jess came on Sat to do the work as agreed, came early in the morning so got an early start and worked solidly through, seems to have done a fine job thanks! The draught proofing looks like it will make quite a difference. Will recommend the company to others.
