Our windows are made with exclusive Fibrex® composite material for greater strength, durability, and style. Fibrex® is made with 40% reclaimed wood fiber by weight and vinyl polymers, so it provides the sturdiness of wood along with the versatility of vinyl. Plus, Fibrex® frames are twice as strong as vinyl, and can hold even very large panes of glass with sleek, narrow frames. Learn more about Fibrex® longevity.

Can You Afford to Skip Out on Professional Installation?

A great window is only as good as the product and installer behind it. A faulty installation can lead to…

  • Cracked joints
  • Loss of heated or cooled air
  • Exposure to the elements
  • Exposure to pests
  • Water infiltration, which can lead to serious damage to the windows and structure of your home

Be sure to call one of our window replacement experts at Renewal by Andersen to get the job done right the first time and avoid these costly mistakes.

20 Year Durability Study

We believe replacement windows should be a lasting, quality addition to your home. Renewal by Andersen window installations are all backed by a 20-year warranty because our products are simply made better and last longer. Recently, our professionals examined several sets of Renewal by Andersen windows that had been installed in a home for over two decades. They had withstood years of extreme weather patterns and regular use without bending, bowing, expanding or peeling—and yours can too!


The Renewal by Andersen limited warranty is one of the strongest you’ll find on any window or patio door of any price. It includes 20 years on glass, 2 years on installation, and 10 years on frame and hardware. It’s non-prorated and fully transferable should you sell your home. Ask your Renewal by Andersen sales consultant for complete details.

I love my new windows, made a HUGE difference in the drafts, keeping wind noise out, and keeping heat in. I also choose a different style and the view is much nicer, easier to open and close

We are extremely pleased with our large dining room window. The old window was not efficient; letting cold air into the house in the winter as well letting heat from the furnace outside! The installer was very professional, efficient and cleaned everything up nicely. The entire experience from sales to installers through follow-up was a pleasure.

Replaced 12 "old" draft double hung windows with new double hung windows. Remarkable improvement in maintaining and constant comfortable temperature in the rooms. Great workmen and a great finished job.

Unrivaled Style

We believe replacement windows should be a lasting investment that reflects both your home and your lifestyle. That’s why we offer custom options at every stage to make any window or door completely your own.

Choose from 7 functional and stationary window styles—including specialty, custom-shaped windows. Consider a traditional double hung window to complement the look of a more historic home, or accentuate a modern look with a sliding style. Either way, all Renewal by Andersen windows feature slimmer frames and greater window area, because of their tough Fibrex® frames.

Fibrex® window frames also provide a longer-lasting color and shape than standard wooden or vinyl windows. This is because of the Fibrex® extrusion process, which allows frames to be saturated with color for a flake free finish over time. Plus, our windows’ composite materials hold their shape without bending or bowing for straight, clean lines for years to come.
