Joseph A De Mella Plumbing

Joseph A De Mella Plumbing works out of Cambridge and says it has covered the Greater Boston area for 35 years, offering residential and commercial plumbing and heating work with 24/7 emergency calls and free estimates. Its public ratings don't line up with each other. Google carries a single 1-star rating, a separate directory profile on US-Info shows the same 1.0 score from its own lone reviewer, and an unclaimed Birdeye page puts it at 3.7 across three reviews — three different reads on the same business, none resting on more than a handful of reviews. Boston's own permit records tell a steadier story: the business has filed 21 plumbing permits since 2011 and closed out 91% of them, a completion rate that holds up even though the review sites disagree with each other. Given how thin and conflicting the online ratings are, ask for a recent, verifiable reference before booking rather than leaning on any single star rating.
