Building on our industrial success, G.C. Zarnas offers a dedicated Commercial Painting Division focused on architectural needs and cost-effective solutions for new construction and maintenance.
From interior and exterior painting to wallcoverings, preservation, and lead stabilization, we provide the quality and service that make us the contractor of choice for commercial projects.
