Some large plumbing companies in Massachusetts are quoting $8k–$9k for a basic 40-gallon water heater swap that typically costs $1,500–$2,000. For a straightforward replacement—permit, haul-away, no system changes—that markup isn’t justified. Compare bids, hire a licensed MA plumber, and insist on permits and a city inspection. Knowledge is power—don’t overpay for a commodity.
