Lifetime product warranty.

Just as it says: In the event of factory defect or mechanical failure of any Great Windows product, we will repair or replace that product at no charge. (Lifetime Product Warranty coverage excludes defects resulting from abuse, misuse, or improper care and maintenance.) If any Great Windows product requires replacement and the product, pattern or color has been discontinued, we will replace it with a product of similar style and value. (Replacement is limited to the defective or malfunctioning product only.)
