7 Red Flags When Hiring a Concrete Contractor in North Carolina

Over the last two years the NC concrete market has picked up a wave of out-of-state door-knockers who pour bad slabs and disappear before they cure. Here are the specific patterns to recognize and walk away from.

1. No visible NC license number. Any concrete pro doing more than $30,000 of work needs a Limited Building Contractor license issued by the NC Licensing Board for General Contractors. It's a public record — search at nclbgc.org. If they can't produce a number, or the number they give doesn't match their business name, they aren't licensed to do the work.

2. "Cash discount for signing today." Legitimate concrete quotes have a 15-30 day validity window. Nobody serious is pressuring you to sign in the driveway. The urgency is the signal, not the discount.

3. Full payment upfront. NC industry standard is 25-30% down, balance on completion. Anyone asking for 100% up front is either fronting materials on someone else's job, or planning to disappear.

4. No physical business address. Google the address on the quote. If it's a UPS Store, a strip-mall mailbox rental, or doesn't exist, that's not a business you can find in year 2 for a warranty claim.

5. Concrete truck arrives without a delivery ticket. Every legitimate ready-mix delivery in NC comes with a printed delivery ticket showing mix strength (PSI), water added, and load time. If the truck shows up and the crew doesn't check the ticket in front of you, they might be pouring the wrong mix.

6. "We'll do the permit for you after the pour." Permits are pulled before work starts. Doing it "after" means either they don't intend to pull it at all, or they'll pull it under a different scope than what they actually poured, which won't pass inspection.

7. Verbal warranty only. NC good practice is a written 1-year workmanship warranty and passing through the manufacturer's warranty on any sealer or coating. Verbal warranties evaporate the day you cash the check.

If two or more of these show up in the same quote, walk away regardless of price. The cost of a bad concrete job in NC is $6K-$11K to tear out and re-pour a driveway, and it takes 4-8 weeks. Paying 15% more upfront to get a real pro is always cheaper than paying to fix a bad job.
