Michael Mercier Plumbing & Heating

Michael Mercier Plumbing & Heating works out of Salem, Massachusetts, taking on the plumbing and heating calls that come with an older North Shore house — water heaters, furnaces, and the everyday repairs in between. The one detailed account on record describes a multi-year relationship: Mike had already been servicing the customer's combo furnace and hot water heater for years before they decided to replace the whole system. The review credits him with walking the family through every option without pushing a sale, then getting the new unit installed quickly while keeping the house clean. Beyond that single account, the business shows up consistently across several Salem-area plumbing directories with a matching 5-star, one-review footprint, but there isn't yet a wider body of reviews to draw a fuller pattern from. Worth checking before booking: a BuildZoom snapshot from 2022 flagged no active license on file for the LLC, and public permit records tied to the name show several Boston plumbing permits filed since 2011 that remain open. Neither is necessarily disqualifying — permit records lag and license status changes — but they're worth confirming directly rather than assuming. For a Salem homeowner weighing a furnace or water heater job, the one account on file is a genuinely good sign, but it's a small sample. Ask to see a current Massachusetts plumbing license and a couple of recent references before committing to bigger work.
