Rosati Difference


Customer Experiences
"We had gone through local knowledge and the Rosati name kept coming up. When we contracted them, they were very responsive, very knowledgeable and flexible. They showed us the history of what they have done in Windsor and it was extremely impressive. We were also very impressed by the speed with which they could get things done. I can’t say enough good things about Rosati. They work quickly, diligently and effectively, always with the budget in mind. And since they really do have many in-house capabilities, they can move quicker than any other construction team we have ever worked with. We are very satisfied with the work so far.."

Managing Director


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.."
Jonathan Reaume
Owner/Chef


Customer Experiences
"We went back to Rosati due to the ease of working with them. Because they were willing to partner with us again, it also made it easy, and we felt very positive about the Rosati Partnership Program. They were able to facilitate the property and add the building next door, which was ideal as well. Our customers have been very impressed.."
