Dan Phillips was amazing. He sure knows his stuff. He showed up exactly on time. We explored all the options. Gave me a great price with no pressure, I was so impressed by him that I felt that no one would take better care of me, so I chose to work with Champion because of Dan Phillips. If you are in need of windows, doors, or sunrooms, Dan is your guy, he is best salesperson I’ve ever worked with. He’s a keeper

James P. arrived promptly on time. He was very friendly, respectful and extremely knowledgeable. I didn’t know exactly what I wanted for a new front door and James gave great suggestions and multiple options. I highly recommend James and Champion.

Martine and Jared did an exceptional job replacing the roof on my sunroom. I had this sunroom installed by Champion many years ago and it has proven exceptionally beneficial with no issues. They also replaced one sliding glass door (free of charge), which had discolored over the years. Their quality workmanship and timeliness were second to none.

Tricia Ellersick View Review

I love my Champion windows but the screen in the master bedroom window started popping out whenever I lifted it up. I called Champion August 2026 and paid $130. I was told the appointment wouldn’t be until October.
Jesse came out twice. He fixed not only my screen but also replaced the broken parts in my window. They both now literally guide up and down the window track so easily!
Yes, I did have to wait a couple of months for the repair but the windows are 19 years old, installed in 2007. Thank you Champion for standing behind your product. And thank you for sending Jesse. He’s friendly, professional, and communicates well. He got the screen and window working like new!
