Natural Stone Fabricators       Commercial A Contractors       Commercial B Contractors

 

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.

 

EDUCATED CUSTOMERS LOOK FOR ACCREDITED COMPANIES

Natural Stone Institute Accredited companies have met the industry’s highest standards for business excellence. Accredited companies have demonstrated best practices in the following categories:

  • Safety
  • Physical facilities and equipment
  • Finance
  • Employment practices and training
  • Advertising and promotion

When shopping for a natural stone fabricator or commercial contractor, look for the Natural Stone Institute Accreditation seal. It is a meaningful quality indicator because only the finest companies in the industry can meet all of the qualifications necessary to become Accredited. The seal protects residential and commercial customers from unscrupulous business, poor quality product and shoddy workmanship. When you work with an accredited natural stone fabricator or commercial contractor, you can be confident that your project will be completed in a professional manner, that questions or concerns will be promptly addressed, and that your satisfaction will be the company’s priority.
