Red flags before you let a plumber in (North Carolina)
Updated November 5, 2026By the LocalPlumber team
Check the license
North Carolina licenses plumbing contractors through the NC State Board of Examiners of Plumbing, Heating & Fire Sprinkler Contractors. Ask for the license number and look it up on the board's public lookup before work starts. It takes about a minute.
Every plumber in our directory shows a license number so you can check it yourself.
Warning signs
- No price until they're inside. A plumber should be able to tell you the service call fee and after-hours rate on the phone.
- No written estimate. Get the price in writing (a text or email counts) before work starts.
- Pressure to decide on the spot. "This price is only good right now" is a sales tactic, not a plumbing fact.
- Replacement when you asked about a repair. Sometimes replacement really is right, but ask why a repair won't work and what it would cost.
- No camera footage for sewer-line work. If someone says your main line needs replacing, ask to see the video.
- Large cash deposit up front. Small deposits for special-order parts are normal; big cash-only deposits are not.
- No license number, or one that doesn't match the business name.
Fair questions to ask any plumber
- What's included in this price, and what could make it go up?
- What warranty do you give on parts and labor?
- Will this need a permit? Is that in the quote?
- Can you text me photos of what you found?
