Rosati Difference
Customer Experiences
"Their attention to detail was unbelievable. They worked really well with the architect, and real teamwork is required for that. They’re perfectionists, and I respect that. They sign their name to every job and they’re not going to do that unless it’s done right.."

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."
