Boston's Seaport
Behind every thriving neighborhood is the infrastructure that keeps it running. As a Boston-based, family-owned plumbing contractor, E.H. Marchant is proud to have played a role in the transformation of Boston’s Seaport District from an industrial waterfront into one of the city’s most vibrant destinations. From complex new construction projects to cutting-edge plumbing systems, EHM delivers the expertise, reliability, and craftsmanship needed to support Boston’s evolving skyline and thriving waterfront community. If you’ve ever dined in one of the Seaport’s acclaimed restaurants, grabbed coffee at a local café, enjoyed one of its entertainment venues, or shopped in any of its modern retail stores, there’s a good chance you’ve experienced a space where our team played a role behind the scenes. We are honored to be a trusted partner in shaping Boston’s future, one project at a time.
