"RG Construction took the concept from design and budget to building it and everything in between. The stress of the project was very low for me. I was in constant contact with the superintendent and he was present on the jobsite daily. Communication was very good. Overall I am pleased with the end result, the cost, and just my overall experience. They continue to respond to questions I have and stand by their work 100%. Would definitely use them again."
