Today I had the opportunity to meet with Jordan and learn more about Champion products – specifically, vinyl siding. Jordan was extremely professional, knowledgeable, and friendly. He arrived a couple of minutes early, was wearing a Champion name tag, and was patient with my not-so-well-behaved dog. Jordan knows the Champion company history and the science behind the superior Champion products!

I have an older home with an oddly shaped door that needed replaced. Dre Davis helped my partner and I choose the right custom door for our home. During this process Mr. Davis was informative, gave a realistic timeline and expectations, helped us get discounts, and above all was very personable. I feel assured in my purchase and I would recommend Dre Davis by name to anyone seeking to improve their home!
