There are two brothers. I've used both and been happy with both. They were recommended to me by a friend who also really likes them. Don't have the number handy, but they're in the Yellow Pages. Professional, accurate, perfect overall.
Prices are reasonable.
I will use them and only them again if needed. I've always gotten good service from Vickers and Ruth. They're in the Raleigh phone book. He does new construction primarily, though. For clogged pipes, you'll probably need a company like RotoRooter.
