I was brought in on a project with James and his crew at Castlerock Contracting, as an Interior Designer. James was detailed oriented, professional and did everything to make the project go smoothly. His quality of work is superior and he is very dedicated to his clients. He is extremely prepared and works quickly and efficiently. He is great at problem solving with efficient and effective solutions. Whether full gut renovation or a new construction, I would highly recommend James and Castlerock Contracting for any residential work.
