MIA Accredited Company


MIA Accreditation for natural stone fabricators and commercial contractors recognizes those companies that meet the industry's highest standards for business activities, product knowledge, fabrication and installation. MIA accredits companies, not individuals.

  • Quality control
  • Safety
  • Finance
  • Ethics
  • Customer service and education
  • Advertising and promotion
  • Employee policies including training, discipline and termination


MIA offers three categories of Accreditation:

  • Natural Stone Fabricator (primarily residential interior)
  • Commercial A Contractor (heavy commercial)
  • Commercial B Contractor (light commercial)

A company may be accredited in more than one category, depending on its business model.

The Accreditation Program continues MIA's more than 70-year history of promoting excellence and accountability in the natural stone industry. For residential or commercial applications, MIA Accreditation signifies that a natural stone fabricator or contractor:

  • Is experienced in stone fabrication, installation and maintenance is a solid, reputable business
