Johnny Noonan was a terrific sales and customer service rep. He restored our faith that there are still professional people servicing customers’ wants and needs!!!

  • We are putting in a 19 x 20-foot sunroom and Richard Law our salesman was not only knowledgeable but very prudent on time frames. If he said he would be here at 10 he was here at 9:50.

    Stan Reed
  • The experience was amazing. Walked us through the whole process and provided great demonstrations. Was early for an appointment and very kind throughout the experience. Was considerate in allowing us time as a family to discuss the costs after the initial review. Would recommend.

    Monica Nichols
  • Travis was extremely thorough and educated me on the products. I was impressed with the warranty information and the direct from factory customization. I feel really good about the long-term commitment of Champion.

    Nancy Leody
  • Richard Law represents Champion very well. As my home had both warranty and new installation needs, Richard made a second visit so as to coordinate the warranty and new installation people. I found him to be congenial, pleasant, helpful, and knowledgeable. I interviewed two competitor products and once I decided to go with Champion, Richard made a third visit to confirm our agreement. I'm favorably impressed with Richard.

  • Justin did an excellent job talking my wife and I through our sunroom options. The presentation was professional, efficient, and Justin did an excellent job listening to our vision and turning that into a proposal. We look forward to working with Champion!

    Alex Carvaggio
  • Justin came by on time to look at our dream project - transforming a back porch into a sunroom. He was thoughtful of our needs and budget and presented us with something that was just want we were looking for. The quote he gave us was 60% less than a competitor. We have used Champion for new windows in the past and have faith the rest of the project will go as smoothly as the initial step.

    Tim Ringwood
  • Rich came to our house to give us a consultation and estimate with a very thorough presentation. He was very professional while very down to earth. He was patient and interactive with our dog and young son. He answered all our questions and was on time. He gave us time and privacy to think about our decision and laid out all our options clearly. We signed the contract that day and hope the installation is smooth as well.

  • Justin and Chris came out to do measurements and provide a quote for a sunroom addition to our house. They were extremely friendly, professional, and made sure we understood exactly what our options were! We were SO excited to move forward with them and some financing situations on our end made us hit a roadblock. We will be contacting them in the near future to complete our project. They were extremely impressive in their knowledge and customer service. We very much appreciated their understanding of our situation as well.

    Tyler and Jessi Clouse – Bass
  • Dan was amazing! He was very low pressure and very down-to-earth! He did a great job of walking us through the options, outlining the differentiators, and relating to our needs. This is a guy and company who genuinely cares for their customers. I have already started recommending Dan and Champion to several of my friends!

    Ashton Sommers
  • Ryan came into the house with a great attitude and was very knowledgeable and helpful. He worked with us to get the price needed and the work requested to be done. His honesty and professionalism was nice to see and appreciated. We needed to get this work done and he was able to deliver all that we needed. I would recommend Champion for all window and siding projects.

    Bill Seiwald
  • We actually set an appointment to get an estimate for a covered patio. We have put that on hold for a bit, but we did have windows and a new front door quoted. Our Salesman was Rich Law, and he was fantastic. Our appointment was supposed to be 1 hour, and he spent over 3 hours with us. His professionalism and knowledge of literally everything Champion had to offer was outstanding. We ordered a new (custom) front double door and replacement windows for a portion of our home. We felt like Champion was in line with pricing and we took advantage of several discount offers/incentives that they were offering at the time. We're excited to get going on final measurements and proceed with making our home more efficient. Thank you, Champion!!

    I'd like to recognize the lead installer, Todd. He was fabulous to work with. He answered all of my questions and called me about what needed to happen. We even ran into a couple of problems during the installation and my husband called him about them. He was right on top of it and they were fixed immediately. He had his crew in line and they performed exactly how he told them to. He was the best!

Champion are welcomed to come place a sign in my yard so others can see who did the work on my house. This area is actually a great place for them to advertise their services because there are a lot of individuals in my area are looking to add additions to their homes.

    The salesman, George. Ben, and Joel (the installer). I had a few emergencies with my cats and then I ended up in the E.R., they were all great to me and very flexible. They did not treat me like a car salesman selling a car to a woman. Very respectful.

  • I was very satisfied with the finished product and it's quality. They were very accommodating when it came to our dogs and not disturbing me during the day while I was sleeping.

    Pam S. of Littleton
  • I wanted to thank you for getting us involved with Champion Windows. This has been one of the best investments we have made in our home. The windows look great and have made a remarkable improvement to our home. The first thing we noticed was how quiet our home became. As you may remember our home backs to I-25. The night our windows were installed was the first night in 25 years that we didn't hear the highway. The week after our windows were installed it got back up in the nineties. What a difference our Champion Windows made. In the past our air conditioner would have to run all day to keep the temperature in our home below 74%. Even in the nineties it stayed cool in the house without the AC running. We have never actually sat down to figure out how much we've saved in the utilities but our bills were much lower this winter and I'm sure we will save even more this summer. Thank you again!

    Gale and Joanne Swope
  • We were extremely satisfied with the product we purchased from Champion. We feel we got the right window for our needs and budget. We didn't feel pressured by your sales person and your installation crew was courteous and professional. We can only say other vendors didn't want our business when they didn't meet our expectations like Champion did. Thank you so much.

    Jessica Conrad
  • The first time we've had anything done right the first time. Everyone was courteous and responded to our input and requests at all times. Thanks for such a professional & friendly staff.

    Bob and Linda Maltese
  • Appreciated the quality and the quickness of my window installation. Nice crew to work with. Love my new windows! They cleaned up every little mess that was made. I wouldn't know they had even been here except for the new beautiful windows.

    Linda Conca
  • Very pleased with the quality of the windows. Paul, my installer made a dedicated effort to install and insure the quality of my window. I am very pleased with the overall experience, with the purchase and installation of Champion Windows products.
