- Ask for the license number and look it up yourself on the state or city license search. Licensing is set by the state in some places and by the city or county in others.
- Ask whether the job needs a permit. Water heater swaps, gas work and moving fixtures often do, and the licensed plumber pulls it.
- Get the price in writing: a flat rate for the job, or the hourly rate, the trip fee and how parts are billed.
- For emergencies, ask what the after-hours rate is before the plumber drives out.
- Ask who does the work. A licensed master can send helpers, but the license holder is responsible for the job.
