5 starsJC 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!Review fromDariana R

5 starsWe 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.
