" We chose Halfmoon Green Building because of their experience and expertise in all areas of construction. We made the right choice. Andy and his Company did excellent work and in a timely manner.  We felt like it was a collaborative effort, with Andy suggesting improvements to our initial ideas.  He also was accomodating when during the project, we changed plans a little."
