We worked with Steve and his family-owned company on a mudroom and garage/ADU addition, as well as a finished basement and deck, and had a great experience from start to finish. Steve was excellent with communication, easy to work with, and consistently helped us problem-solve and refine ideas throughout the build. Along with his crew, Tim and Andrew, the entire process was smooth and well managed, and the quality of the work is excellent. Each space came together beautifully and fits seamlessly with our home. We’re extremely happy with the results and would highly recommend Steve and his company for any home addition or renovation!
