Excellent work RBA! Junior and his team who did the installation of our new windows were on time, polite, courteous, hard working and meticulous in their work. We highly recommend the team at RBA. Their customer service, quality of product and guarantees are well worth the investment.

From the 1st appointment to installation they have been very communicative with me. The only problem we had was the RAIN, they had to reschedule & were able to do the next day. Always on time for my 3 appointment. Great installation very professional from day one. We had 4 installed

I had a great experience with Renewal by Anderson. The sales rep, Stephen, was extremely knowledgeable and was able to demonstrate the superior craftsmanship of their doors and windows. The process was clearly explained and this is a company that takes real pride in its work. Unfortunately, I was unable to proceed forward with the installation due to personal reasons. However, I will be having Renewal by Anderson install my doors and windows when the time is right. Their customer service line was also easy to follow and got you on the phone with a real human quick, instead of giving you the robots and runarounds that are so common place nowadays. I'd give six stars if I could!

Mike, thank you so much for the wonderful review! We are thrilled to hear that Stephen took great care of you and left such a wonderful impression. We can't wait to work with you in the future when the time is right!

I want to thank RBA for supplying such a quality product.and that installation matters! When working with the product manager "Nick" on an installation error, he went above and beyond to provide corrections to make sure that I was satisfied with my purchase. RBA should be fortunate that he is on their team! Nick chose superior carpenters to correct the installation and their work was impeccable! Thanks to "Carrie" who was always available for consultation!
RbA of Westchester, NY (534) replied on Sep 29, 2026:
Joyce, thank you for the high praise! We truly are happy to have Nick and Carrie on the RBA team, and they will be absolutely thrilled to hear how much you appreciated their support and the crew's hard work. We appreciate your patience and understanding!
