Additions and Remodels
"We hired Ben to remodel our living room and kitchen, which included adding approximately 300 square feet, creating an open floor plan, and removing an enormous brick fireplace in the center of our house. From day one, Ben was amazing to work with. He was on budget, on schedule, professional throughout the entire project, and consistently anticipated potential issues before they became problems. His wealth of experience was incredibly valuable when it came to making decisions along the way, and he was always willing to offer thoughtful advice and guidance. His entire team was fantastic as well: professional, respectful, and clearly committed to doing quality work. We couldn’t be happier with the results and our experience working with Ben. We highly recommend Ben for any remodeling, building, or construction project!"
