Renewal by Andersen Windows Warranty

Renewal by Andersen® Corporation Limited Warranty
For Renewal by Andersen® Products and Installation

20 - 2 10 Limited WarrantyYour Renewal by Andersen® products are warranted under a fully transferable limited warranty covering parts, labor, and original installation services as follows:

Twenty (20) year limited warranty for glass

The insulating glass in Renewal by Andersen® window sash and door panels is warranted to be free from defects in manufacturing, materials and workmanship for twenty (20) years from the original installation date. Insulating glass is warranted not to develop, under normal use and conditions, any material obstruction of vision resulting from manufacturing defects or as a result of premature failure of the glass or organic seal. Slight glass curvature and minor scratches or other imperfections in the glass that do not impair structural rigidity or significantly obscure normal vision are not covered by this Limited Warranty.


If your Renewal by Andersen window sash or door panel glass
is found to be defective, we may elect to either repair or replace the defective sash or door panel, at no cost to you. Such repairs and replacement parts are warranted for the remainder of the original warranty period.

Two (2) year limited warranty on installation

Installation of your Renewal by Andersen window or door products by an authorized installer is warranted for a period of two (2) years from the date of original installation. During this period, should your Renewal by Andersen window or door fail to perform according to our specifications due to improper original installation, we will bring the workmanship up to our professional standards, at no cost to you.

This Limited Warranty on installation does not extend to labor/services performed by anyone other than the original authorized installer, nor to the installation or repair of any finishing or other materials that have been applied to or adjacent to the product after the initial installation.

Ten (10) year limited warranty for components other than glass

The frame and sash members of your Renewal by Andersen window are constructed of Fibrex® material. All Fibrex material components of your Renewal by Andersen products are warranted not to flake, rust, blister, peel, crack, pit, corrode, or rot, under normal use, for ten (10) years from the original installation date.

The non-glass components of your Renewal by Andersen windows and doors are warranted to be free from defects in manufacturing, materials and workmanship for a period of ten (10) years from the original installation date. This includes, but may not be limited to, components such as locks, lifts, balance systems, hinges, handles, insect screens and weatherstripping. During the warranty period, we may elect to either repair or replace any defective Renewal by Andersen products or components for you, at no cost. Such repairs and replacement parts are warranted for the remainder of the original warranty period.


The following sections provide an itemization of conditions and events not covered by this Limited Warranty, and an explanation of how to obtain help under this Limited Warranty.

General conditions and exclusions

The limited warranties set forth in this document are the only express warranties (whether written or oral) applicable to your Renewal by Andersen windows and doors, and no one is authorized to modify or expand these written warranties. All warranty claims must be made during the applicable warranty period.

ALL IMPLIED WARRANTIES INCLUDING MERCHANTABILITY AND FITNESS FOR A PARTICULAR USE WILL EXPIRE WITH THE TIME LIMITS OF THE LIMITED WARRANTY TERMS SET FORTH ABOVE.
