20 Year Durability Study
When we say our windows are built to last, we mean it. To test their quality, we pulled 20-year old Renewal by Andersen windows out of their openings to inspect them. These replacement windows had weathered two decades of every type of weather in a variable climate. They had been used often in all seasons, and hadn’t bent, bowed, faded, chipped or broken down over time.
That’s the kind of lasting durability you can expect from every custom window designed and installed by our window contractors. See the Renewal by Andersen difference for yourself!
