Find an Accredited Company
The Natural Stone Institute, the natural stone industry’s leading information resource and advocate, established the Natural Stone Institute Accreditation Program to reinforce a level of professionalism in the industry, and to provide designers and consumers with an easy to find collection of qualified stone professionals. The Natural Stone Institute Accreditation Program is the only independent third-party credentialing program for natural stone fabricators and installers. Accredited companies are reviewed to ensure best practices are in place, tested on proper fabrication and installation methods, and inspected to ensure safety, fabrication, and installation standards are met. The Natural Stone Institute accredits companies, not individuals.
