Over the past 3 years I have had several windows replaced in a 50-year-old house, all done very well and in a timely manner. Most recently John Paul installed a new patio glass sliding door after removing the old broken one. He did a great job in just 2 hours! I will likely use Champion Windows again.

My husband and I were blown away with the crew that came out to install new windows. Everyone was polite, professional and friendly. Keep us informed as the day went. They stayed focused from start to finish. Did a great job cleaning up. Very happy with the results. Next, are 2 new doors. Highly recommend this company.
