We had a great experience with a large renovation project. Eric and his team are very professional and great to work with. There are hundreds of decisions in a home reno and he helped us think through them all. He explained options and different price points clearly. He made sure the work was done well, even catching and fixing small things we didn’t notice. Wouldn’t hesitate to work with them again or recommend the to others.
They fixed a construction issue for us professionally and seamlessly!
