About Us

Our Mission crop

Founded in 1948, G.C. Zarnas is a leading certified SSPC QS-1, QP-1, QP-2, and QP-8  national contractor that performs a variety of industrial and commercial specialty services. These include the application of high performance and specialty coatings, industrial and commercial painting, tank linings, intumescent and cementitious fireproofing, shop coatings, abrasive and sand blasting services, lead abatement, and concrete and masonry repair and restoration services.

A third-generation privately owned and operated industrial and commercial specialty services firm, Zarnas performs multi-million dollar maintenance and new construction specialty coatings for heavy-duty industrial projects within the power, petrochemical, chemical, marine, government, water and waste water treatment industries.  Our commercial division performs coatings and restoration services to the interior and exterior of a multitude of commercial and historical structures in education, healthcare, business and industry, lodging, stadiums, recreation, warehousing, and storage. 

Safety is our top priority as evident by our Experience Modification Rate (EMR), which falls well below the industry standard. This commitment to safety is based on caring for our employees, the clients for whom we work, and the communities in which we operate.


“As a former competitor, I have known G.C. Zarnas to be an aggressive and competitive bidder. Because of their experience and history in many industrial market segments, they have a realistic appreciation for the actual cost of a project, and the organization to get the job done.”
