Limited Warranty

G-OLOGY® doors and windows are guaranteed against defects in materials and workmanship for a period of one (1) year from the date of production. G-OLOGY will furnish replacements for hardware and components that prove to be defective with prepaid shipping. At its discretion, G-OLOGY will issue a refund of the purchase price of such parts in lieu of furnishing a replacement. No labor or installation is included.
