Came out for the estimate in a timely manner and provided a competitive quote. An install date was provided and they called the day prior to confirm the install time and showed up the next day right on time. I'm a lifelong DIY person so I'm really fussy about the quality of work, and I have to stay I was impressed with the care taken to make sure everything was done correctly, I have no problem recommending them and will use them again.

We used the company to remove & replace drafty front door, leaking very large picture window in front of house, and shutters for exterior refresh. Team on the job was mature, adequately staffed, and clean with no problems couldn't work through logically. Communication was clear. House looks 15-20 years younger states the neighbors. Recommended

We were very pleased with all the employees of J. C. Tonnotti we have had contact with from the sales person to the office staff to the installers. The quality of the windows and door as well as the workmanship when your crew came to install them last month was obvious. They arrived promptly, reviewed the rooms where the installation was to take place, and got right to work. They were organized, respectful of our property, diligent workers, and cleaned up completely before leaving; in other words, professional. Any interactions with your workers was polite. The crew leader gave us a clear demonstration

We used JC Tonnotti for replacement of all of the windows in our house (26 windows plus sliding door). Their estimate was fair, the quality of their product (Harvey) excellent, and the entire process went smoothly, from quotation to ordering to delivery and installation. High praise for the sales person, office staff, Joe himself, and the installation crew. Every one of the people who came to tear out and install the windows was pleasant, contientious and courteous, making the 2-day installation process as painless as possible. The quality of the work is excellent, and we will be reaching out for
