It is a pleasure to recommend TCK for the excellence of their work, their highly professional approach, thorough preparations and care in carrying out their work. After very poor work carried out by a previous company, TCK started with a clear description of the work required to address the problem; they noted potential hidden issues, and described the type and quality of materials they would use to ensure long-term reliability. TCK carried out the work efficiently and with minimal disruption, kept me informed of progress and allowed me to inspect the work as it was done. On completion they cleared up any waste very thoroughly. I am pleased and completely satisfied with their efforts and have no hesitation in recommending TCK to potential customers.
