Artstone gives a 15- year guarantee to the person or company that purchases the product as of the invoice date the product is purchased. Under normal terms of use, Artstone products are guaranteed against any problems that might arise from the production. Structural deteriorations such as superficial cracks, rotting and breakage are under the guarantee. In case that there is an unusual deterioration in the product during the guarantee period, it can be reported with a written petition and a photo of the impaired part by agreeing with an Artstone authority. If it is deemed appropriate as a result of the examinations, Artstone is responsible for replacing only the damaged part with a new one or refunding the individual or company as only the damaged product's panel value.
