These guys are absolutely professional - they did an excellent job at my old house in 2014 and when I moved to my new house in 2016, I did not even bother calling anyone else, I just called Kemal and he was at my house in a jiffy, took the measurements and his superb crew did a truly fantastic installation once again !! I only wish all Contractors could be like United Stone & Kemal ! I would recommend these guys in a heartbeat ! Kemal is also a really friendly guy with a great sense of humour - all in all a very satisfying experience dealing with them.
