A Few of Our 5-Star Customer Ratings
“Ron’s team did quality work. After he did a major renovation at my son’s home I asked him to replace my very old sliders and windows. His window team did a great job. When each day was complete you could never tell anyone had been there because they cleaned and picked up everything. Would recommend Mainville windows and doors.”
“We had 1960 era sliding doors replaced on a three season room by Ron and his crew. The whole process was easy and the new Harvey doors and all the trim work looks great!”
“No pressure sales for Harvey windows was from Mainville Windows and Doors. All discussions and negotiations were from the owner. Quotes were provided, accepted and ordered the same day. The removal and installation of 17 windows was completed in one day with expert care and knowledgeable installation. The whole process was a job well done. I would recommend Manville Windows and Doors to anyone.”
Ron and team did great work on our house! We contracted with Mainville Construction to do our entire kitchen renovation. The quality and service was outstanding. They were very detailed and genuinely cared about the customer wants. In our kitchen renovation we had two windows removed and one moved & enlarged. We couldn’t be happier with how it turned out and the advice Ron provided to us on what would look best- he was right! Great quality work!
Ron is great guy and he was very professional and he walked us through everything to do the windows. Handled challenges well since we had an old house to replace the windows.
We worked with Ron the owner. He was very knowledgeable and honest. Pricing was more than fair and we really like being able to work directly with the owner instead of a salesperson. His crew was clean and professional and they were done in 2 days. I would highly recommend them.
Ron replaced our slider, 4 interior doors, and a kitchen window as part of as part of a full renovation. The slider replacement required some unexpected additional structural repair and they were able to handle it all with ease. We were lucky enough to hire someone with enough experience to recognize there was an issue and fix it instead of just putting the new door in without addressing it. You can’t go wrong here.
The Mainville team did a great job for us. Work was completed all in one day. We couldn’t be happier with the outcome. All the windows fit snug and tight – no more drafts! This is the second project we’ve hired Ron Mainville and his team to do for us. We are so happy with our choice of contractors. A quality job, no hassles, good value. We can recommend Mainville Windows and Doors without reservation!
Ron and his guys do quality work. They have fixed or replaced almost every area of my home. I have a beautiful new bathroom and kitchen thanks to them. Ron responds quickly to my calls and is on site frequently to ensure that everything is done just right.
Mainville provides excellent craftsmanship at reasonable prices. We have used them multiple times for different projects including window replacement and a full kitchen remodel. We recommend them HIGHLY and will be using them again.
