As an architect whose practice operates across multiple continents – with studios in New York and London and projects spanning the globe – I have had the privilege of working with many exceptional specialists and craftspeople over the years. Gary stands entirely in a category of his own. His approach to the repair of our Schüco terrace door at our London showroom was nothing short of extraordinary. If I were to describe his method, I would say it sat somewhere between the precision of a surgeon and the patience of a master watchmaker. He diagnosed the problem immediately, executed the repair with complete confidence, and left everything in perfect order.What impressed me most was that Gary did not simply address the task at hand. He cast a trained and generous eye across adjacent details, flagging things that warranted attention and sharing observations that only someone with truly encyclopedic knowledge would notice. His command of hinge technology – its history, its current state, and where it is heading – is something I have genuinely never encountered before. And I work with specialists every day.He was also gracious and forthcoming with his knowledge throughout, despite other work happening concurrently that day. That kind of professionalism is rare anywhere in the world. It is rarer still to find it combined with such warmth and genuine enthusiasm for the craft. Open Ensure has earned a client for life. I would not hesitate to recommend Gary and the team without reservation.”
