Great job by these guys! Had our front door and 5 windows replaced and they even went above and beyond touching up some of our existing windows. Really impressed and would highly recommend!

Everyone on the crew was professional and hard working. Our older home required 2 days for all windows and doors, but they still took a few extra minutes to make a nice cosmetic patch for an ugly repair in our siding. Highly recommend and have already passed their name off to a couple of inquiries

Great experience with Prime installing a door for us. Very friendly and knowledgeable during installation. Door looks great and left everything very clean. Highly recommend!

I am totally impressed with the team at Prime Windows & Doors. From the initial meet and greet with their sales professional, employees working with us to choose the window and finally the three professionals who installed the door. Highly recommend and will use this team again.

As always! Super Happy with the windows and install! 🤗🤩The boys were awesome! 🤗🤩They go up and beyond what is there job. When asked they will try and comply. In my case they installed some window trim in my daughter's room that was very sentimental to us. It was a trim my husband had made along with the bedroom for our daughter before he passed. I was afraid to put up as I didn't want to wreck it. The fella installed it for me and did a fantastic job. Both myself and daughter were very happy!💞 It completes the beautiful room her Dad made for her graduation!😇💞 The new windows and doors all installed by Prime Window and Doors makes my house look so much nicer in appearance! I highly recommend them. The guys are all good,very professional,kind,curtious and never leave a mess! There office administer Allana is a dear to deal with. 💞She will always answer any questions you have and gets back to you promptly! Thank You all for making my house look great and me so happy!

Most professional company for windows in Belleville and surrounding area. I hired them to change all my house windows, and they did it all from outside in a way that I never had to touch up any paint. And their team of professional installers got the job done in 5 hours for 7 windows.

"Replaced our sliding patio door. The install crew arrived on time explained and showed me what they would do. Removal of the old door and replacement with new was very quick. They also installed interior trim that perfectly matched our existing baseboards. We are very pleased with our new door."

“Very professional and conscientious, good quality work. Did what they said they would do, at the price quoted and completed work within timelines. Polite, respectful and cleaned up after themselves.”
