David Bott View Review

After almost 50 years as a hands on residential contractor, I find myself unable to do it myself, so I need new windows in my home of 44 years. I contacted Champion Windows. By the end of my career after having installed Pella, Anderson, and a host of other name brand windows, I had decided that vinyl windows were the only way to go. To keep this review short, I’ve begun the process with a Champion representative who came to my house. I know windows, but the presentation of the Champion product by the rep was worth the time and effort he put in to show my wife and I the product options while being very attentive to our needs and wants.
Next comes the installation rep to take accurate measurements before the order goes to their factory in Ohio here in America.

I’ll let you know how things go as the process continues.
