MJM Construction

Bathrooms are the clearest read on MJM Construction. The most detailed recent public comment is from a homeowner who had two bathrooms renovated and singled out the finished work, the attention to detail, and the way Jon and Mario stayed available through the project. On its website, the Beverly company says it has handled home building, remodeling, and renovation work on Boston's North Shore since 1998. The public review trail is small, so this is not a contractor with years of dense online commentary. Google currently shows six ratings at 5 stars, and the written comments that do turn up lean positive. The newest one, posted in April 2026, describes MJM as responsive and flexible during a two-bathroom renovation. That light volume is the main thing to weigh. Most public comments tied to the company center on bathroom work, so if you're hiring for a broader renovation or something outside a bathroom remodel, ask to see recent projects close to your own. Its Massachusetts HIC license is active, which is useful to confirm up front, but the more practical question is who will be your day-to-day point of contact on the job. MJM fits best when the project is a bathroom remodel and you want a North Shore general contractor rather than a single-trade specialist. Before signing, confirm recent examples similar to your scope, who will run the work day to day, and how the schedule will be handled.
