50 Year Limited Warranty

Assuring our products' quality

Foster Rock Veneer offers a fifty-(50) year limited guarantee on all vertically applied veneer stones, to include water table sills and trim stones. Stone veneer must be installed as per NCMA-MSV guidelines; any deviations from this detailed installation process will be null and void. Veneer stones and accessories that are deemed replaceable under our warranty will only include the veneer units, not labor, and must be inspected by a representative of FRV (Foster Rock Veneer). Any damage caused by delivery or mishandling of veneer units is not covered under our warranty. FRV must be notified by letter within 7 days of noticing any defects and FRV will respond to the letter within 30 days of receipt. FRV is committed to our customers and our goal is to rectify any issues that may be related to our manufactured stone in a timely manner.
