While Renewal by Andersen of Long Island is proud of our full portfolio of home improvement products, we understand our customers want (and deserve) the peace of mind that comes with knowing we back our replacement windows and patio doors with an exceptional product warranty. We hope you’ll never have to make a claim, but if you do, we want the process to be smooth and effortless.

What You Need to Know About Our 20/2/10 Warranty Package

Your Renewal by Andersen of Long Island purchase is warranted under a fully transferable policy that covers parts, labor and the original installation. A transferable warranty means if you sell your home, the warranty transfers to the new owner. The warranty does not follow the window or patio door, meaning windows removed and installed in another home are no longer covered.

20-year Coverage on Glass & Fibrex Window Frames

Glass: Glazing is warranted to be free from manufacturing defects, including materials and workmanship, for 20 years from the original installation date. The warranty covers factory glazed windows, including all Low-e4 high-performance, patterned glass, tempered versions and divided light grilles. The warranty does not apply to impact-resistant glass, art glass and special order glass. Renewal by Andersen will repair or replace glass when changes in appearance develop due to premature failure of glass or original seals.
