John Flynn

John Flynn founded Ruislip Windows in 1986 and still runs it today, alongside his son Joe. He came into the trade as a City and Guilds qualified carpenter, so he was cutting and fitting joinery long before he ever quoted a window, and it is still how he judges a job. Across four decades he has watched the materials, the building regulations and the standards of the industry change almost beyond recognition, and he has installed through all of it. He writes about how windows and doors are made, fitted and specified, and what makes one last longer than another.
