  Thoroughly recommend, brilliant job

  Posted 25 January

  Ryan was absolutely brilliant from quotes through to completion. He was responsive, knowledgeable, considerate and very professional. Easily the best tradesperson that we've dealt with!! We'd thoroughly recommend (and will keep his number if we ever need new windows again!)

  Outstanding window specialist

  Posted 10 December 2025

  Ryan is brilliant and a genuinely nice chap. He’s hardworking, polite, punctual, and highly knowledgeable about windows. I needed 9 large sash windows and a door replaced in my Victorian flat, and he was helpful from the start, patiently walking me through the options. Even with several changes on my side, he adjusted quickly. Although the manufacturer delayed the windows by three weeks and I had a tight deadline, Ryan worked overtime and weekends to get everything done. Renovations can be stressful, but having Ryan handle the windows made a huge difference. I would definitely recommend him.
