Testing, Maintenance and Construction Services

Griffin Certified provides a full range of services to the petroleum, bulk fueling facility and fuel station industry. From designing, producing plans for permitting, obtaining permits, and completing the work, we are there to ensure a smooth process. Customers find the best value when they have us do all three types of work: Testing, Maintenance and Construction.

This keeps facility downtime minimized. We also minimize the need for subcontractors by doing nearly all work in-house such as plumbing, electrical, excavation and concrete work. This reduces costs, increases efficiencies and minimizes scheduling issues.
