What a "Concrete Pro" Actually Means in North Carolina (And How to Verify It)

The word "pro" gets used loosely in the concrete world. Anyone with a mixer and a screed can call themselves a concrete pro on a business card. In North Carolina, there is no single state license for residential concrete work under a project value threshold — which means the burden of vetting falls almost entirely on the homeowner. Here is what actually separates a working pro from a guy with a truck, and how to verify each item in under fifteen minutes.

First, the general contractor license. North Carolina requires a general contractor license from the NC Licensing Board for General Contractors for any project with a value of thirty thousand dollars or more, including labor and materials. Below that threshold, no state license is required, but the contractor must still register with the county in most jurisdictions. You can look up any GC license at nclbgc.org and confirm the license class, expiration date, and disciplinary history. A pro doing residential driveways and patios will typically hold a "Limited" or "Intermediate" classification.

Second, insurance. Ask for a certificate of insurance — a real one, not a photograph of an expired page. General liability at one million per occurrence is the residential floor. Workers compensation is required in North Carolina for any employer with three or more employees, including part-time and seasonal. If your pro says "I work alone," you can still ask for a workers comp waiver on file with the state. Every legitimate pro can produce these documents within a few hours.

Third, ACI certification. The American Concrete Institute runs certification programs for flatwork finishers, decorative concrete pros, and concrete field testing technicians. It is not required by state law, but it signals a level of ongoing education that separates a career pro from a self-taught operator. ACI Flatwork Finisher and ACI Decorative Concrete Flatwork Finisher are the two most common for residential work in North Carolina. You can verify current status through the ACI online lookup by name.

Fourth, county registration and inspection history. Every county in North Carolina has a permitting office, and most residential concrete work exceeding a value threshold requires a permit. A pro who has pulled permits in your county before will have a track record with the inspector, will know the required rebar spacing and control joint layout for your soil class, and will not disappear if something fails inspection. Ask which counties they regularly work in and call the permitting office to confirm.

There is a fifth signal that is not a credential but is worth as much as one — a working pro will happily give you the phone number of a homeowner they worked for six months ago. Not a testimonial, not a review — a phone number. If they hesitate, that tells you what you need to know.

Putting it together, the four minimums for a residential concrete pro in North Carolina are current GC license (if the project is over thirty thousand dollars), general liability insurance, workers comp compliance, and county registration in the jurisdiction where you live. ACI certification is a strong plus. All four can be verified in under fifteen minutes with a laptop and one phone call, and a pro who cannot pass that test is not one you want pouring your driveway.
