    I am very impressed with how efficient and professional all of the Renewal by Anderson employees have been throughout my entire project. The sales representative was very friendly and patient with me during the initial visit. Once I agreed to the project and price, I was told exactly what would occur and exactly when. Then a gentleman came to do precise measurements for my new patio door. He also was very helpful and explained the process to me again. That helped reinforce the next step. Then a gentleman had to come to make sure there was no lead in the walls or paint, because this house is 40 years old. I was again reassured that even if there was lead based paint, the project would begin when promised, but that the installers would need that information. Then came the day that my door was to be installed. The installers arrived on time and were extremely courteous, knowledgeable, and very professional. The installer and his crew was fabulous!! I cannot remember his name but he represented Renewal by Anderson at the end of the process, and he was terrific!! If and when I replace all my windows, I will request the same wonderful young man and his crew to do the installation!!! I am an extremely satisfied customer, and would highly recommend Renewal by Anderson!! Thank you
