Emerson Mechanical Contractor LLC

Call at seven on a weeknight with no heat and, by more than one account, Emerson shows up in half an hour. Emerson Mechanical Contractor — EMC — works out of Billerica, and its Massachusetts plumbing licence is active, held by Emerson Dos Santos himself. Speed is the through-line across 80 Google ratings averaging five stars, 39 of them written in the last six months. A homeowner whose basement ejector pump failed on a Saturday says the crew arrived within an hour or two, replaced the pump the same day, then cleaned and sterilized the area. Another, writing in October 2025, called late on a Saturday afternoon about a dead water heater and had Emerson leave his son's birthday party at seven that evening to look at it. The work runs well past drain-and-faucet calls. One customer's second-floor bathroom was leaking into the living room below; the crew used a scope camera to locate it instead of opening the whole ceiling, and on a later visit swapped a corroded shutoff valve that a big-box delivery crew had refused to touch. A food-truck owner had EMC pipe and install the gas system on a mobile pizza trailer. In a December 2025 review, a homeowner described new plumbing for an upstairs laundry stack plus a repair under a hundred-year-old bathtub that had been leaking into the kitchen below. Heating and cooling turn up nearly as often as pipes: a central air conditioner serviced and a dryer vent cleaned on one visit, an AC condenser diagnosed the same day on another, a no-heat call answered during a two-foot snowstorm in January 2026. Two other things recur. Pricing gets described as fair, with the quote given before the work; and communication by text and phone stays quick. One customer says Emerson has been their plumber for four years, and a condo building that deals with many vendors calls him their favorite. The caveat is how young the written history is. Every review on file was posted in 2025 or later, and almost all of it sits on Google — deep and current, but narrow. For emergency plumbing, water heaters, heating callouts and gas work around Billerica and Greater Boston, this is a straightforward call. Get the scope and the number in writing before the truck rolls, the way their reviewers describe being quoted.
