Pat was just so knowledgeable and a delight to work with. He demonstrated how well the product is made and knew an answer to questions I didn’t know I had. It was so easy, and I’m so excited to see the finished product! It was simple to schedule the installation and it was done fast!
Love these windows!! I do have one cracked window waiting for a replacement, and I wish they wiped the install dirt off. It’s cooler in the house, the road noise is gone, and the house is completely transformed! Beautiful Thank You!!!!!! The repair was a whole new window and it’s installed less than an hour! Definitely satisfied for the work Champion did for us!

Michael Fay made it an easy decision for me. He was extremely thorough, educational and a true joy to work with. I was given cheaper prices, but decided to continue with him due to his honesty, integrity and work ethic. I highly recommend working with him and look forward to enjoying the sunroom in which I have always desired!
