20 Year Durability Study

A lot can change in 20 years’ time. Your windows shouldn’t. Recently, we pulled a group of our original windows out of their home, more than two decades after installation. These were the actual windows that had been in a real home, being operated by the homeowners on a daily basis…and enduring extreme weather conditions. With more than 20 years of enduring extreme climate –bitter, brutal winters; hot, muggy summers and everything imaginable in between, the original Renewal by Andersen windows still opened and closed as easily as the day they were installed. And what’s more, our Fibrex material retained its strength, and there was no cracking, peeling, or chipping. This is the quality that you can expect from Renewal by Andersen replacement windows and patio doors.

Warranty

Every Renewal by Andersen window and patio door installation is backed by an unbeatable 20-year limited warranty. 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 written details.

Beautiful French & Sliding Patio Doors

Just like our replacement windows, Renewal by Andersen patio doors are made to last with durable materials. Available in hinged and two types of sliding varieties, patio doors are also custom-made to fit you. Try a colonial or prairie grille to match a historical style, or fully open your home to the outdoors with clear frames. Either way, patio doors by Renewal by Andersen offer durable functionality and design for years to come. Read about the benefits of each patio door style.

Testimonials

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.
