Essential Facts About Renewal by Andersen®’s Window Warranty

Window replacement is a significant investment in your home’s security and resale value. It doesn’t come cheap, so it’s only reasonable to have an assurance that your windows can actually last for a long time. Renewal by Andersen® understands this need deeply. That is why we offer our customers one of the strongest warranties in the industry.

Why We Stand Behind Our Products and Services

Andersen windows are made from superior materials and top-notch technology, which enable them to last as long as their warranties. This gives customers like you some peace of mind that the money you have spent on your windows will not be put to waste. Renewal by Andersen values the trust that clients have given, and the company proves time and time again that it is worthy of that trust.

What You Should Know About Renewal by Andersen’s Window Warranty

Whether you choose sliding windows or double-hung windows, it’s important to know what their warranty covers. Renewal by Andersen offers a 20-year limited warranty on the Fibrex® material as well as on the glass in window sashes and patio doors. Meanwhile, a 10-year warranty is provided for other window or door parts, such as hinges, handles, locks, lifts, insect screens, weathering strips, finishes and balance systems.

Fibrex windows are designed to resist rust, rot, flaking, cracking, peeling, pitting and blistering under normal use within a span of 10 years from the day of installation. The glass is guaranteed to have zero defects in manufacturing, workmanship and materials from the day of installation. If you opted for insulated glass, you can rest assured that this won’t develop any problems that would obstruct the view or leaks in the seal under normal conditions and use.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
