The History of Quinn's Installation Contractors

Dennis Quinn Sr. started this company almost fifty years ago in 1972 with little more than a truck and a dash of entrepreneurial spirit. At the time, his son William (Willy) and Dennis Jr. were only four and two years old respectively, but it wasn’t very long before his sons showed an interest in the business that would grow into their leading roles today.

In the beginning, Dennis Sr. worked with a small crew of laborers on various local siding and roofing projects, but as word got around about the high quality of his team’s work, the business began to expand and evolve. Soon, the team was able to offer top quality window and door replacement services. This is when Dennis Sr.’s sons, William and Dennis Jr., were able to get involved in making Quinn’s Installation Contractors a family legacy of excellence.
