    We just moved to CT and have been renovating our new home. Picked J.C. Tonnotti from a local publication. Pricing was great and the service and quality of work was fantastic. They have been added to our address book for future projects.

    J.C. Tonnoti saved me lots of money by replacing the panes in my bow window instead of me buying an entirely new on. They did an excellent installing the window panes and two doors. They were quick, clean, and professional. Everything looks and works great.

    JC Tonnotti built and installed 23 windows for us this year. This huge project included the consolidation of 5 pane windows instead one big one, replacement of three huge sliding glass doors and the removal of a bay window and replacement with a flat three pane slider.
    When I say this company is great, it’s a massive understatement. Their professionalism is unmatched and their employees are far and away the kindest contractors I’ve ever come across.
    If you’re contemplating working with this company, do it. You won’t find a better window company anywhere in Connecticut!

    We had heard amazing things about JC Tonnotti so decided to go with them for a couple window replacements and for a bay window installation, best decision we made. They were very respectful of our home and placed drop cloths anywhere they would be working and along their walking paths. After the job was complete, they vacuumed and cleaned up any mess. We were home during the entire process and overheard the employees constantly making sure that everything was aligned perfectly. I highly recommend this company if looking for quality work and great service. The gentleman that initially came for the quote and final measurements was extremely knowledgeable and answered questions in great detail. The truck driver who delivered our windows the day before installation couldn’t help but to sing their praises. Great experience beginning to end. Nothing but professionalism beginning to end.

    I used this company a few years ago to replace my front door. I was very happy with their work and just hired them again to put a new garage entry door into my garage. The job was finished today and like I expected they did an excellent job. Clean, neat excellent workmanship and a job well done. I would highly recommend this company to anyone who needs doors, windows or siding done to your home. A company that’s been around for 40 years.
    A Dependable reliable business who takes pride in their work.

    RUN FAST VERY FAST
    This review is happening because of poor workmanship a less than a year after the job was done, I am including the whole story because it needs to be known why I refuse to call them to fix the issue.
    We had an issue with our basement windows. After many calls to various companies we settled on using Tonnotti. I am a huge advocate of using the mom & pop establishment. From the moment of contacting them we were upfront & honest that we would need to finance the job after the down payment. Every time we spoke with someone we got a song & dance about looking for a new company with better terms for financing.
    Skip ahead to the installation day, the work is completed & we were asked for payment. Imagine our surprise when that happened, we explained about the financing & the worker said he would have someone reach out to us. The office called & explained that their finance company didn't finance anything under $3,500 and we would have to find another way to pay. I was furious and told them so. I felt like we had been baited & switched because they knew our position.
    Then last week with all the rain we came home from a funeral service out of state to find out basement once again filled with water. You maybe asking yourself well how can that be? When we cut away the expanding foam the silicone they used around the window was a joke it was minimal & it pulled out without any effort. So now having to not only deal with a home in New Hampshire that a tree fell on, a mother who's had to move into assisted living I now have to deal with trying to find someone, I will have to pay more money, reliable to come in & fix the shawty workmanship of a shady company.
    Thank goodness we had the floor done not soon after so the water cleanup is so much easier.
    Update 7/17/24 the new pictures added to the end are from the rain on the 17th...this is what 3k gets you.

    Had all the windows along with 2 sliders and an entry way door replaced. Cannot say enough about the installers! They were very professional, knowledgeable and respectful of my home. Luke was very nice to speak with and he took the time to explain everything. The 2 installers, Josh and Matt, were very polite and they installed 4 windows on one of the hottest days in June. They did the job extremely well and left the areas very neat and clean. Would highly recommend them to anyone.
