North Shore Cleaning Systems, Inc.

North Shore Cleaning Systems is a Beverly outfit whose center of gravity is other people's workplaces: offices, dental and medical suites, child care rooms, schools. Its own site leads with commercial janitorial work — day porters, floor stripping and waxing, tile and grout, carpet and upholstery — and lists residential cleaning alongside that rather than in front of it. If you're a homeowner calling, that's the first thing to know. The company's BBB profile puts it at 17 years, started in August 2009 and incorporated in 2018, run by owner Jerry Sheehan with two employees on the books. It carries an A+ grade there, though it isn't a BBB-accredited business. Its stated territory is eleven North Shore towns: Beverly, Danvers, Hamilton, Lynnfield, Marblehead, Middleton, Peabody, Salem, Swampscott, Topsfield and Wenham. The written history is where a homeowner should slow down. Google shows 5★ from 13 ratings — a clean number, but eleven of the twelve reviews on file arrived between late June and early August 2026, in a tight cluster, and they read alike: professional, punctual, thorough, spotless, with almost no job-specific detail. One recent commenter does place the work in an office, writing that it looked cleaner than it had in months. The single older comment, from August 2024, is the most concrete of the set — a customer describing an after-builders deep clean of an apartment and calling it good value for money. So: a long-established Beverly cleaning company with a plain commercial specialty, and a review history that is almost entirely a few weeks old and light on particulars. That isn't a mark against the work itself. It is a reason not to lean on the star average. If you need recurring janitorial coverage for a small office, medical practice or school on the North Shore, this is the kind of shop built for it. For a house clean, ask directly how much residential work they actually do, who would be on your crew given the two-person headcount listed, and for a couple of local homeowner references you can call.
