We recommend inspecting stone veneer and cast stone twice a year, cleaning with a mild, pH-neutral detergent, and resealing every 3-5 years depending on exposure. Proper flashing and correct mortar joints at installation prevent water damage-our installation guidance ensures those details are done right. After installation, we offer post-install support and maintenance advice to keep surfaces looking great and lasting longer. Learn more and get local help: Hunter-Stone.com🔧���
