Mosaic products are covered by an industry-leading
Limited Warranty, providing peace of mind that Mosaic products will last.
These are not just values. These are the guiding frames and hinges of how we think, build, and serve. These are the ISMs of Mosaic Windows & Doors. We don’t just manufacture excellence — we live it.
If you have a warranty claim, please contact the retailer from whom you purchased your Mosaic window or door products, as they are near you and familiar with your purchase and/or project. Please provide the retailer with the serial number found on your Mosaic window or door products. For more details, see How to Identify Mosaic Products.
If you purchased Mosaic products through a builder or a remodeler, you may need to contact them to find out the name and location of the Mosaic retailer with whom they placed your product order. If you cannot determine the name of the retailer or distributor, search the Mosaic retailer locator or call 800.209.3015 to find the one nearest you.
The retailer’s service representative will help diagnose the problem and determine if the parts are covered under warranty. If repair or replacement of materials is required, there may be charges for parts or labor.
