First Installation: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 of how the windows work for cleaning, etc. All in all, it was a very positive experience and we have already placed an order for more windows and another door to be replaced by J.C. Tonnotti.Second installation:We recently had a second round of windows and a new front door unit installed by J. C. Tonnotti. The workers arrived on time, reviewed the rooms in which they were doing the installations and started right to work. They worked quickly and efficiently, leaving openings to the outdoors (in February) for as short as time as possible. One team member had to leave to pick up some additional materials which delayed their progress, but they stayed until the job was finished and completely cleaned up. Our house is much brighter and warmer thanks to the fine job they did.

We had a front screen door as well as a smaller kitchen and large living room and kitchen window installed in January 2022. The installers were here for 6 hrs and everything was done efficiently and professionally. You wouldn't know they had even been here! Cleaned up nicely when they were done. Joe came to see us before the work was done and went over everything. We have already noticed how much warmer our home is...on top of how wonderful the windows and door look. Would highly recommend them for your home improvement needs...Thank you!!!!

J C Tonnotti replaced all the windows in my house. From the initial meeting to the installation of the windows, it was clear that this is a reputable, professional company focused on the client. Chris and his crew clearly were expert installers but were also very respectful. Although it was a cold day in February, they worked quickly and efficiently to avoid excess heat loss! When they left the house, each room was as clean as when they entered. Beautiful windows, excellent company.
