“
Gulian was so great to work with that we miss having him around now that our project is complete. Core Builders respected our home and left a clean job site at the end of each day. Gulian is so even keeled. We were never made to feel that any of our new ideas, added scope or change in direction were ever a problem. Gulian offered suggestions on where to spend and where to save for best value. He was excellent at communicating where we were at and what was next. We were never left guessing. I ha
