20 Years of Confidence
Our Fibrex® material windows are not only beautiful, they are scientifically proven to stand the test of time.*
The promises you hear when you replace your windows are only as good as the company that stands behind them. For more than a century, Andersen® products and patents have revolutionized the window and door industry.
As the full-service window replacement division of Andersen Corporation, we are uniquely able to present Renewal by Andersen Signature Service: the perfect combination of a superior start-to-finish process, the best people in the industry, and decades of exclusive product innovation.
It’s safe to say that rigorous testing—both in the lab and in the field—is one of the hallmarks of how we do business.
Beauty Backed by Science
Recently, we pulled a batch of our original windows from the home they had been installed in more than two decades ago.** That’s more than 20 years of extreme Minnesota weather—bitter, brutal winters; hot, muggy summers.
And what did we find? After all those years of enduring Mother Nature’s mood swings…they passed our battery of performance tests with flying colors. After two decades in a real family home, facing real weather…they still looked brand new, and they still opened and closed as easily as the day they were installed.***
A Lot Can Change in 20 Years…Your Windows Shouldn’t.
