How many plumbing contractors are in Maine?

Together they employ 4,613 people, with an average yearly payroll of $378,485 per business. The three busiest counties hold 52% of them, so competition is packed into a few places.
With 1,395,722 residents (Census, July 2023), that is one business for every 1,858 people, against 3,051 nationally: fewer residents per business than the US average, so more competition for each job.
