Not scored yet

The TSBPE register publishes no issue date, complaint record, bond or insurance for this licence, and a score from Google reviews alone would say little about the licence. So it isn't scored, and it's listed after the scored plumbers in Austin. It gets a score as soon as the board publishes more.
