Homeowners Love Working with Great Day
The sales rep Wayson who came to my house was very easy to work with. The 2 men who installed my windows and doors did an excellent job. I really appreciate that they cleaned up everything and took all the old ones. My new windows and doors are beautiful and work so easy. So glad I went with Champion for my new windows and doors.
The salesman was professional, respectful and very knowledgeable and helpful in any of our needs for our project
Ron was very nice and took the time to go over all of my questions and break down pricing on everything. He made sure to quote me exactly what I wanted
Extremely pleasant experience buying my widows!!
Dre was great. Very informative and helpful. Definitely recommend him if you’re looking for a quote!
Just had a presentation with Brent J of Champion Windows and I have to say it was extremely informative and well thought out. Left nothing to chance, went over everything and then some. Would highly recommend Brent J coming to your home. He did awesome!!!!
Melissa was very good. She explained everything well. She was very knowledgeable. I was disappointed that you charge extra for color and limit the colors that can be chosen. Also, you are more expensive than your competitor which, to be truthful, I was not expecting.
The presentation was good to go through to see how the windows are actually built and getting a good explanation of the warranty.
I was really concerned when I saw the reviews!, But I had absolutely no problem with my purchase. It arrived ahead Of time, excellent quality, efficient installation, and one happy customer!
I would definitely recommend
The Bath Authority was an amazing business, the workers are kind, very hardworking, and on it! Especially one particular worker, Kane Mercekllio. He was really on it prices were very great better than other businesses way better. 5 star review, keep it up!
Brian was great, talked us through everything and very professional!
My husband and I had a consultation with Jason Powers about adding a sunroom to our home. We didn’t retain services w/Champion but Jason was so helpful, knowledgeable, and provided many options. His customer service is impeccable!
