Brooke Gamble is an outstanding representative for Champion. Throughout our consultation, she was professional, kind, and exceptionally patient. She remained transparent about every step of the process and demonstrated thorough knowledge of the product. She carefully explained the quality of the materials, the manufacturing and construction details, and the advanced glass technology designed for superior cooling comfort. She answered all of our questions and concerns thoroughly, and we never felt any pressure to make a decision. We are grateful for the excellent experience and highly recommend Brook. She is a true asset to the Champion team!
Great product and customer service!
Had a very good demonstration
Our experience with Caleb was great. Very good presentation and explanation of project. We got a quote for a sunroom and while he explained prices, there was not a whole lot of pressure to make a decision same day.
Jeff is very professional. His presentation was excellent. He was knowledgeable, very detailed, and patient.
Trevor was great, professional, and informative. Great demonstration.
We appreciated the opportunity to work with Mark Watkins and look forward to our finished 4 season room
Had total replacement sliding doors installed with a doggie door added!!! It’s an answered prayer for us & the dogs!!!
Wonderful experience and customer service in the replacement of my front and back door!
I recently had a representative come to my home to quote new windows. While I am not ready to pursue next steps at this time the presentation was extremely helpful in understanding the replacement window process. Their product demonstration was very thorough and interesting. Thank you Kevin.
Jeremy was Awesome! Very knowledgeable and friendly. Exceptional in explaining the product and not pushy!
