Note: It is important to recognize that Coastal Stone Company’s stone veneer products are an adhered veneer or façade which are attached directly to a cementitious substrate for purposes of providing ornamentation and a first layer of weatherization protection. Adhered Concrete Masonry Veneers are not intended as a structural product or a waterproofing element. Most importantly, the real subject matter expert is your local building department and the local building code. Your local building code will supersede all other written or verbal installation guides provided by Coastal Stone Company or the NCMA.

Please notify Coastal Stone Company if you feel the manufactured stone has a manufacturing defect.

If the product is determined to be defective, Coastal Stone Company, will replace the defective manufactured stone.  This warranty will apply to the manufactured stone products only and not the installation based on the fact that Coastal Stone Company has no control of the installation.
