The Renewal by Andersen Difference: Signature Service

When you choose Renewal by Andersen, you get more than just new windows and doors—you get our Signature Service. This unique, start-to-finish process is designed to make your renovation as smooth and stress-free as possible. We handle the details so you don’t have to.

Here’s what that looks like:

Expert Design Consultants: Your journey begins with a friendly, in-home visit from one of our design consultants. They listen closely to your needs, understand your vision, and help you choose the perfect windows and doors for your home. There’s no pressure—just helpful guidance every step of the way.

Precise Measurements: Our Project Technicians visit your home to take detailed measurements and confirm every specification before your order moves forward. They also address any last-minute questions, making sure your custom windows and doors are built for a flawless fit and smooth installation.

Custom Manufacturing: Once your design is finalized, every window and door is custom-built to your home’s exact specifications at our Minnesota-based manufacturing facility. Each piece is crafted with precision and attention to detail, for a perfect fit and flawless performance. To make it even more personal, your name is printed on the box—because this project is uniquely yours.

We believe a home improvement project should be exciting—not stressful. With Renewal by Andersen, there’s no middlemen, just one company handling your entire project start to finish.

We stand behind our products and our work because we want you to feel confident in your investment. With Renewal by Andersen® Acclaim® windows and Acclaim Impact windows, you’ll receive the Nation's Best Warranty† Coverage, offering protection for both your products and their installation.

We also cover both your new Ensemble® entry doors and their professional installation, giving you complete confidence that every detail is handled by experts. This means no hidden costs, no worries about workmanship, and the assurance that your investment is protected for years to come. Unlike some companies that tout a ‘lifetime warranty’—which often doesn’t cover the lifetime of the product or excludes installation—our coverage is clear, comprehensive, and designed to help give homeowners peace of mind.

What makes Renewal by Andersen’s limited warranties among the best in the industry?

• 20-Year Warranty on Glass and Fibrex® Material

Engineered for Performance, Designed for Your Home

Renewal by Andersen® windows and doors are more than just beautiful—they’re engineered for performance. Every product is crafted with advanced materials for durability, energy efficiency and long-term value. 

At the heart of each window is our exclusive Fibrex® composite material, a unique blend of wood fiber and polymer that combines the strength and stability of wood with the low maintenance of vinyl. Fibrex material never requires painting and will not crack, pit, corrode, or rot, even in extreme weather, and it’s proven to stand up to decades without losing its shape or beauty. That means less maintenance, better energy performance, and windows that look just as good as they perform. No other company sells Fibrex material, making it truly unique to Andersen Corporation.

During product development, our team puts every design through rigorous testing to make sure it meets—or exceeds—industry standards for strength, efficiency, and weather resistance. Because each window and door is custom-built to your home’s exact measurements, you’ll enjoy a perfect fit. Because our windows are installed within 1/16’’ of your home’s opening, it could help cut down on your energy bills, too.

Durability That's Built to Last

After 20 years, our windows still open and close as effortlessly as the day they were installed.** 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.**
