I had an great experience with certified windows. The owner came out to take a look at my windows and give me an estimate; he wasn’t pushy which I really appreciated. Once I decided on what I wanted, his team set a plan and was very efficient in their work. Would highly recommend for anyone who needs windows!

Fast, friendly, efficient, fair prices.... who could ask for more? And my dining room already feels so much warmer (winter time) with a new patio door that is insulated and installed properly. Highly recommend!
