Rosati Difference
Customer Experiences
"Rosati has been a tremendous help. I’m so happy I went this way, It was just so easy. Other people have to be on top of their builders, but it’s pretty much been the opposite with Rosati. They’ve been great at keeping on top of things and meeting the timelines.."

Customer Experiences
"Tony and Nick Rosati are great to deal with – it is like dealing with family. I would highly recommend them as they will ensure all is done in a timely manner and are very flexible meeting our crazy working schedules in the automotive industry. They go out of their way to ensure very little disruption occurs to our production of six days a week.."

Customer Experiences
"Rosati is a quality bunch of guys. They know their stuff. They know our industry,” said Circle 5 co-owner Keith Lavergne. “Hiring Rosati saved us from going to several sources to get several parts of the project done ourselves. Rosati is truly a one-stop shop for industrial expansions and machine foundations. Everything’s on schedule and within budget. Rosati is a good company to work with."

Customer Experiences
"We were very impressed with the quality of work on Phase I, and that Rosati was able to meet our tight timeline. This was important because some of the practitioners were just starting their practices. Rosati delivered, and we were impressed. There was no question we wanted to work with them again on Phase II.."
