Full Lifetime Warranty For as Long as You Own and Reside in Your Home

Milgard Manufacturing Incorporated ("Milgard") guarantees to the original consumer purchaser ("Original Purchaser") of Milgard windows, doors* or skylights (hereafter referred to as "Products") installed in a single family home or a multi-family home unit ("Home") by the builder as new construction or by the Original Purchaser as replacements, that Milgard will repair or replace any such Milgard Products** that are defective in materials or workmanship and will pay the costs of all parts and labor. If repair is not commercially practical or cannot timely be made, then Milgard will, at the Original Purchaser's option, either replace any defective Milgard Products or refund the purchase price.

Persons Covered

This Warranty extends to the Original Purchaser of Milgard Products. The Warranty starts on the date of purchase of the Home as new construction or the installation of Milgard windows, doors or skylights in the Home as replacements ("Start Date") and remains effective as long as the Original Purchaser owns and resides in the Home. In addition, if the Original Purchaser sells the Home before ten (10) years has elapsed after the Start Date, Milgard will automatically extend full coverage under this Warranty to the new owner(s) of the Home and any subsequent owners, until the tenth (10th) anniversary of the Start Date.

Exclusions from Coverage

This Warranty does not cover damage or defects relating to misuse, abuse, the use of applied tints or films, alterations including but not limited to customer-applied finishes, normal wear and tear, broken glass***, natural weathering of exterior finishes, acts of nature (e.g. fire, hurricane, etc.), building settling, structural failures of walls or foundations or improper installation, storage, or handling or failure to properly care for and maintain the Milgard Products****. Normal wear, including discoloration, on hardware component finishes is not a defect and is not covered by this Warranty. Loss of functionality of hardware (except as provided below for stainless steel hardware*****) in highly corrosive environments, which includes any Home located within two miles of salt water and any Home located in the State of Hawaii, is also excluded from coverage. This Warranty does not apply to any Milgard Products that are installed in a Home that has a non-drainable EIFS or DEFS siding product.

Milgard WoodClad™ fiberglass windows and doors may, as an option, be purchased with unfinished wood interior surfaces that must be finished prior to, or immediately after installation for maximum protection. Unfinished wood surfaces that experience water damage at the jobsite or are left unfinished after installation and become stained or damaged will not be considered as defective in materials or workmanship under the terms of this Warranty.

Limitations on Remedies

In no event will Milgard be liable for incidental or consequential damages (other than labor to repair or replace Products, screens or stainless steel hardware under this Warranty), whether based on breach of express or implied warranty, breach of contract, negligence, strict liability or any other legal theory. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

State Remedies

This Warranty gives you specific legal rights, and you may have other rights which vary from state to state.

* Fiberglass Doors

Within Milgard's fiberglass door offerings, only the Ultra™ and WoodClad™ product series are covered by this Full Lifetime Warranty. Milgard Fiberglass Entry Door Systems are not covered under this warranty, but are covered by a Limited Warranty, which may be viewed at

** Screens

Milgard will replace any Milgard window or door screen frame and mesh that is defective in materials or workmanship at no charge to the Original Purchaser (Milgard will pay for parts and labor) for a period of one (1) year after Start Date.


For the Tuscany™ series of Milgard Products only, the Full Lifetime Warranty will extend to glass breakage including tempered glass, unless attributable to acts of nature (e.g. fire, hurricane, etc.), civil disorder, building settling, structural failures of walls or foundations or improper installation, storage, or handling. Specialty glass (e.g. V-Groove, laminated glass) is not covered by this glass breakage warranty.

**** Proper Care and Maintenance

Please see and carefully follow the Care and Maintenance Instructions on the second page of the downloadable certificate (below) or go to Milgard's Care and Maintenance web page.

***** Hardware

Milgard will replace at no charge (parts and/or labor) stainless steel hardware that loses functionality in highly corrosive environments within one (1) year after the date of installation of the windows, doors or skylights as new construction or as replacements.
