Why Choose Renewal by Andersen’s Replacement Windows & Patio Doors?

Our company has devoted a full century to improving upon our craft. We’ve put that time to good use – our windows and doors offer more energy efficiency, aesthetic beauty, and innovation than ever:


Vinyl and wood have their strengths, but neither material has what it takes to create the perfect windows and doors. So when Renewal by Andersen set out to create windows and doors of a higher standard, we first needed to create a superior new material; the result of our innovation was Fibrex – an amazing, patented material that you’ll only find in Andersen family products.

Fibrex® will retain its handsome appearance for decades, yet will never require maintenance. It’s strong, which allows our windows and doors to feature the most energy-efficient combination of glass and frame. It’s an excellent insulator that won’t expand or contract during changes in temperature. And, because Fibrex uses recycled wood fibers, our products are environmentally-friendly.


Renewal by Andersen gives you the option to create your own custom windows and doors from hundreds of combinations of exterior sash, frame and trim colors, as well as a wide variety of interior wood colors and finishes. You’ll find the perfect style to complement virtually every room, every home, every neighborhood, and – most importantly – your good taste.



When it comes to replacement windows and doors, precision has its purpose. So before we build a window or door, Renewal by Andersen will measure its opening to within a sixteenth of an inch. Building to that precision allows us to install our products with a minimum of on-site adjustments and alterations. Only this way can we achieve the perfect combination of frame and glass for your opening – an essential step in achieving the highest standards of energy-efficiency as well as beauty.
