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 recently had JC Tonnotti replace all of the windows (26 plus sliding door) in our home, and we were amazed at the efficiency of the installation crew. In one day they had all of the old windows out, and the new ones installed. Second day they install the trim and it was done. They cleaned everything up so you could not even tell that they… were there. Everyone from the sales person to the office staff to the installers were pleasant, helpful and always on-time. We definitely recommend JC Tonnotti as a class company that does excellent quality work at a reasonable price.

I highly recommend the team from JC Tonnotti for window replacement. They just completed a job at my home. Replaced all our windows including an oversized picture window and replaced our front exterior and storm doors and did some decorative vinyl trim work at our front entrance. From start to finish a very positive experience. I especially want… to thank Henry,the Harvey window delivery driver who went above and beyond and actually helped me rearrange my garage so that the supplies would be in a safe location for the installers. I want to recognize Mikey,Mike ,Steve ,Chris and Carlos who

Very nice that the owner comes out and does the estimating. However, the positive experience stops there. If you want to overpay for shoddy and poor workmanship, then use Tonnotti. Damaged my walls, didn't caulk where they removed trim, and put back broken trim in several places. Tonnotti changed my contract unilaterally by deciding that he wasn't going to do certain work because I am having siding done with no credit or consideration for that. Very thankful they are not doing my siding!!

I had 9 replacement windows installed. The employees, Chris and Carlos did an excellent job. They were professional, knowledgeable, polite and completed the job, cleaning everything up when they were done. My windows are beautiful and it was great to not have rattling, drafty windows while storm Henri plowed through the state. My windows held up beautifully. I highly recommend J.C. Tonnotti, great staff and they answered all my questions.

A couple of weeks ago we had a new patio door installed by JC Tonnotti Window Company. Joe was fantastic helping us choose a very nice door for the space. What a difference this new door makes! We were absolutely pleased with the communication from LeAnn in the office and most of all the installation was seamless! Both Mike and Carlos were very… polite, efficient, courteous, safety conscious and were neat and clean during the whole installation process. They answered all of our questions. We are extremely satisfied and highly recommend this company for all your home improvement needs!

I like to take this opportunity to review my experience with JC Tonnotti. Several months ago, I had Joe and his crew replace 26 windows, 2 entry and 2 storm doors as well as the siding on my 82-year-old home.
I knew there was likely going to be issues with rot on an exterior wall and wanted a company that would be able to handle any framing or other unexpected issues which may arise without having to bring in any additional outside contractors. I met with six competitors and received estimates. I either felt the estimates were inflated for comparable products or, frankly, felt uncomfortable with
