20 Year Durability Study
To ensure true, long-term durability, we put our windows to the test!
After 20 years of extreme temperatures, weather changes, sunlight, moisture, and regular interior use, we pulled Renewal by Andersen windows out of a home to inspect them. Our specialists found that not only did the windows operate just as well as the day they were installed, the frames had not chipped, cracked or faded in 20 years.
This is the Renewal by Andersen difference, and the reason all our home improvements are backed by a limited 20-year warranty.
Warranty
The Renewal by Andersen limited warranty is one of the strongest you’ll find on any window or patio door, at any price. It includes 20 years on glass, 2 years on installation, plus 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 details.
