Rosati Difference
Customer Experiences
"Rosati’s design-build expertise allowed them to take my ideas and put them on paper from a concept and then to a master plan. During any renovation there are always surprises, and this project was no different. When there was an issue, Rosati would tackle it right away, not only with what the problem was but also showing us different options on how to fix it with minimal delays.."
Jon Palmer
Customer Experiences
"We choose Rosati Construction for this project because of its step by step expertise and resources. Rosati's array of in-house services, including design/build capabilities makes the project as risk free and stress free as possible for us. We were also impressed by the fact that Rosati was able to come in under the budget we had established.."

Customer Experiences
"We’re probably one of Rosati’s smaller clients, but they make you feel as if you’re one of the biggest. They are always easy to reach. It’s been a pleasure working with them. Subway outlets get updated and refreshed every seven years, and we’re excited to update our existing stores to the new theme. We plan to use Rosati for that, as well as for future expansions of our chain.."

Customer Experiences
"We appreciate Rosati’s high professionalism in keeping to deadlines, keeping promises, and also being flexible. When you’re starting your process you see things that need to be done differently, and they quickly respond to any changes we require from them. They will try to accomplish everything to keep within the timelines and budget, and come up with solutions quickly for every challenge.."

Customer Experiences
"It was a no brainer to approach Rosati, after having such a great experience with our first new build in Windsor, Rosati's turnkey approach to construction saved us time and money. They helped us source the right land, design the building and ultimately built our new facility. The facility with Rosati’s quality touch will allow us to continue to grow and contribute back to the community of Chatham-Kent. Rosati provided us with options for changes that somehow find the rare combination of achieving our request and staying within a reasonable budget. They don’t put forward just one solution; a spectrum of options allows us to make better decisions to balance design and budget. Rosati’s work is top notch and their ability to manage a project – from design, to paperwork, to construction – is among the best we see across the country. ."
