Two Decades of Extreme Weather Testing

We recently tested Renewal by Andersen® windows installed more than 20 years ago. These windows withstood over two decades of extreme Minnesota weather*—brutally cold winters, hot humid summers, and everything in between.

And what did we find as a result of these performance tests? After all those years, enduring some of the biggest weather swings Mother Nature can dish out, in real situations, operated by real people, our windows still opened and closed as easily as the day they were installed* and they still looked brand new.

*See limited warranty for details. Based on testing of 10 double-hung units 20 years after installation.

In the event a Fibrex material component fails as a result of a defect in manufacturing, materials or workmanship within the limited warranty period, Renewal by Andersen, at its option, will: (1) provide and install the appropriate replacement components or (2) provide a factory-authorized repair to the existing product. Such replacement or repair is warranted for the remainder of the original limited warranty period.

Hear From Our Customers

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgeable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
