Find Renewal by Andersen in Buffalo, NY

Great product; excellent service!!! From beginning to end, and even after the product was installed, these guys were still going. For those complaining about price!! Don’t be ridiculous—if you want a cheap product, go to a retail store—you get what you pay for. A good solid door that will out-live me, and be good for my kids, when I pass this house on. Anyway, thanks Ryan and Mark!! I am very happy and will be calling again for a couple more doors. Regards Ryan.

Micheal Priviteria came to my home and was very Positive!! My husband had a brain bleed 4 years ago and his interaction was such a blessing and was very needed for him and me. Tthis was definitely a great experience! Thank you!!!

Mike Bow was very professional,courteous and attentive to my window needs.

This is the third time we have used Renewal for our window installation. The team is always professional and polite, and the service crew is extremely respectful and considerate. Not only would I use their services again, but I would also recommend them.

I had a great experience with Renewal 5 years ago when the replaced a patio door. I hired them in the spring of 2025 to replace 10 windows. ( approximately $ 24,000). It was a terrible experience this time. They incorrectly measured the size of the windows. The 1st set of installers started in June. Since the window size was incorrect they built the trim into the windows. I have pictures to attest to all of this. I had no alternative but to go with these windows and trim since they had removed all of my old windows and it was unbelievably terrible looking. Management came that day, agreed it was incorrect & poor workmanship. They redid all the trim and caulked using the wrong color of caulk. Different management came and agreed that the caulk needed to be redone ( they tried painting over the other caulk)- that didn’t work, they recaulked and it was sloppy with a lot on the siding of the house. In all, they redid the caulking 4 times, redid the interior trim 3 times ( pieces falling off, joints were off, pieces misaligned), exterior aluminum wrap was completed 3 times. Installation took from June- October. The general manager (Mike) stepped in during the final stages. To his credit and integrity, he viewed the second last process and stated that this was unacceptable workmanship and did not meet the standards of the company. They took a small discount off. The windows themselves are of good quality and Mike reaffirmed that I wasn’t being unreasonable. Unfortunately, this was a home improvement that went terribly wrong from the beginning. I have ti replace the rest of my windows and unfortunately cannot hire Renewal by Anderson again.

The entire experience with Renewal By Andersen has be exceptional; sales, measuring, service department, and installation. We could be happier with are two new exterior doors with storm doors and bathroom slider window. We can highly recommend them for your door and window needs. The installation crew was friendly, courteous, and professional. A shout out and thank you to Carlos, Jaydon, and William. Also to the assistant install manager, Gary Hendrick.

Michael Privitera was great, professional and honestly straight to the point on answering any questions my wife and I had. Recommend 1000000%

Corey was great! I’m really excited about my fibrex windows. Corey was very professional and knowledgeable and explained everything! Can’t wait! Thank you!

We are very happy with the service we received from Mike Bow and Renewal by Anderson. We had bought two patio doors through Mike last summer and everything went as planned. Mike was very helpful to us when choosing our doors. 2026 we are replacing the rest of our windows and were happy to have Mike Bow be our salesman again! We had another great experience with Mike. He was very informative and helpful. We cannot wait till all our windows and doors are Anderson Renewals!
