So let me ask???
  • Are you getting the customer service you deserve from your current testing vendor?
  • Are your results available within 24-36 hours of testing, or are you having to wait weeks to get them?
  • Are you getting competitive prices and discounts for testing combinations?
  • Do you have a contact person; who is readily available to work with you personally to fight or resolve those pesky NOV(s); without numerous emails and phone calls?

Call us today to discuss your testing needs and let us build a solution to meet your needs


The importance of company history is to build a role in trust and respect, to our existing customers and to the customer that has yet to come along.

Every company is shaped with events that have taught us, inspired us, and gave us disappointment and courage.

We here at PS&C are no different. We have spent the last 18 years learning practices, growing in knowledge and building a business that you have come to depend on. For this, we say "Thank You!" You the customer are the most important aspect of our business and without you we would not be the company we are today.

Many people have asked over the years; how PS&C came into existence. Our story is quite entertaining and most importantly God blessed from the beginning.

Our History

Petroleum Service & Calibration, Inc. was founded in May of 2000.

With a meager beginning; we stepped out on faith and gave God full control of our business. True to his word; he blessed us and continues to do so daily.

Who are the owners and what do they offer me, the customer?

  • Jeffrey D. McCrary
  • Jean Jenkins-McCrary

Our owners have compiled years of experience in this industry and bring the knowledge of rules and regulations with a "fire" to stand behind our customers allowing them to be the front person in their tie between the state regulators and inspectors.

Jeff McCrary began building gas stations at the young age of 16 shoveling pee gravel on the construction side. His curiosity into the testing standards, in 1986, moved him yet again to further his career. Jeff's knowledge of testing regulations, laws, rules and requirements has grown tremendously and tank owners depend on him on a daily basis. Jeff has served on boards and committees of writing and advising on regulations within NC and SC.

Jean McCrary brings to you, our customers, the office knowledge and know-how to build a company where you receive TOP customer service, maintenance of a personal data base of site information, immediate site problem notifications, rapid scheduling of sites on or before due dates; online results and invoicing and a personal contact with our supporting office staff.

These expertises combine to offer our customers the most accurate up-to-date compliance answers to their questions. Both work out in the field (technicians) and our in house support team can be seen in our onsite service.

In 2012; PS&C launched our program, UST-Comp. This program was designed to take our company to the level of offering our customers electronic test results, invoicing, and problem reporting. Our in-house programming allows us to trend, develop and update any new or existing test documents that will keep you in compliance with both the federal and state regulations.
