    We were extremely pleased with the whole Renewal by Andersen experience. We met a representative at the Colorado Home and Garden Show and set up an appointment to meet with a sales consultant at our home. Our sales consultant, Chris, was very professional, highly educated about the products and did not "pressure" us in any way. Chris explained the whole installation process including our need to have our new window trim painted. Chris gave us a referral for the painting, along with a referral to have our blinds and shades removed and reinstalled. We were also extremely pleased with the installers. They were equally professional, knowledgeable and courteous. It was really nice to have great people working on our home, and I was completely comfortable with all the people who did work on our home. The installation work was excellent, I do not have a single complaint and nothing but high praise for the quality of the workmanship. I can not say enough about what a great and positive experience, AND we have awesome new windows!!!

    Thank you to everyone that was involved in getting my new window and door. From sales to installation everyone was friendly and were ready to answer any questions. Thank you again and I look forward to working with you on the remaining windows in my house.

    Tile in the kitchen has been damaged. We are getting estimates for the repair and will submit the bill when the work is completed. Some of the window treatments have required much modification due to the size of the new windows. Simple reinstallation was not possible.

    We couldn't be happier with the whole process provided by Renewal by Anderson. From the sales person to the installers, we have never seen more professionalism in other companies. Because they look so good, when we are financially able, we will have all of our windows replaced by Renewal by Anderson. The saying, you get what you pay for, is definitely the case with your service and your product! Thanks so much!!
