I had contracted previous builders to do a flat roof extension. After 6 months, the roof began to leak. It was clear that the the roof was poorly done. Thomas at TCK came to inspect the site. He was extremely professional in his diagnosis of the problem. TCK sent Christopher, the foreman to the site and the TCK staff set about correcting all the wrongs of the previous build (there were many!). TCK were conscientious of my distress of having a shoddy roof, worked quickly and professionally, and gave updates (and photos) of the entire process from start to finish. I would highly recommend TCK's services. It is building done right, with complete peace of mind for the customer. 5 stars!
