WHY CHOOSE RENEWAL BY ANDERSEN® FOR YOUR WINDOW REPLACEMENT? – PART 3: OUR WARRANTIES

It’s easy to be tempted to simply purchase standard replacement windows from the local hardware store, thinking this will save you money. Before deciding to go this route, however, be sure to consider the downside. For instance, you’re likely to hire a third-party installer for your upgrade. If something goes wrong with the windows or the actual installation, it’s possible that the installer you hire will point you to the window manufacturer and vice versa, adding stress to an already stressful situation. Additionally, whatever warranty you get for the windows or the installation will probably be sketchy.

Reviews

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
