Scientifically Proven to Stand the Test of Time*

A lot of things can change in 20 years. Your windows shouldn't be one of them. Our warranty is our promise to you and it is backed by extensive testing.

We recently tested Renewal by Andersen® windows that had been professionally 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.
