When hiring a plumbing contractor, look for a current state license, liability insurance, workers’ comp coverage, verifiable local references, transparent flat-rate pricing, willingness to pull permits, and warranties on both parts and labor. Avoid any contractor who quotes large jobs over the phone or pressures you into a same-day decision.
