Contracting Installer Membership

In 1944 contracting installers were the primary industry group involved in the formation of our association. Today, the contracting installers continue to benefit from the many services provided by the Natural Stone Institute. The Natural Stone Institute sets the stone industry standards for fabrication/installation and provides many services to assist you! Whether it is offering support with a technical question, providing you with sales & showroom videos or brochures, or offering training resources to help run an installation company, the Natural Stone Institute can make a difference in your success. Don't forget that the Natural Stone Institute represents the entire natural stone supply chain (from the quarries to maintenance) — which means it is highly likely that many of your suppliers are Natural Stone Institute members too.

As a member, we thank you for your support! The Natural Stone Institute is the largest trade association in the world representing the dimension stone industry, and for over 65 years, it has been a leader in providing advocacy, networking, marketing/publicity, information/education, professionalism, and stone promotion.

Technical Expertise

The Dimension Stone Design Manual is the U.S. stone industry's single-source reference for dimension stone design and construction specs and details. The Natural Stone Institute's technical department responds to thousands of inquiries annually from stone installers and others. Access to the Natural Stone Institute's technical staff, standards, and technical bulletins is annually ranked the #1 member benefit.

Many installers lend their technical expertise on Natural Stone Institute technical committees and assist with writing Natural Stone Institute Technical Bulletins. These bulletins provide an ongoing educational resource to Natural Stone Institute members and the design community at large. Upcoming topics cover such subjects as joint sealant design use, air barriers, insulation, crack isolation products, portland cement, flashing designs, and more.

Accreditation — Commercial Contractors Leading the Industry

Natural Stone Institute 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. The Natural Stone Institute accredits companies, not individuals. Natural Stone Institute membership is not required for this program, however, most accredited fabricators are also Natural Stone Institute members.

Commercial Contractors that achieve Natural Stone Institute accreditation (2 classifications available) exemplify best practices in these areas: physical facilities and equipment; business and trade practices; technical knowledge and expertise; quality control; safety; finance; ethics; customer service and education; advertising and promotion; and employee training policies.

Promotion / Awards Programs

Installers have the opportunity to receive worldwide exposure when named a winner of any of the different awards that are available to members. Natural Stone Institute's coveted Awards programs honor and recognize natural stone companies, natural stone professionals, and architects from around the globe. The Natural Stone Institute Natural Stone Scholarship program also recognizes a young professional in the industry with an all-expense paid trip to StonExpo. Learn more.
