Thirty-four building permits and not a single review — CO Marano Builders is a Canton company you learn about through town building departments rather than through anything a customer has written down. Christopher Marano's outfit works both sides of the street, and the residential jobs are substantial ones. A $210,000 rear addition in Milton in 2023, built to house an in-home golf simulator. A $220,000 kitchen-and-bathrooms renovation in Chestnut Hill in 2021. A $100,000 gut of a South Boston property the same year, plus work in Wellesley Hills. That is whole-project general contracting, not a single-trade shop. The commercial side is just as real: warehouse demolition and a loading dock in Hyde Park, a $300,000 conversion of a Braintree doctor's office into a dental practice, a Brockton renovation. Worth knowing if you are a homeowner — this is a firm whose calendar also carries commercial work, so ask early where your job sits in the queue. On paperwork, BuildZoom lists a Massachusetts home improvement contractor registration, 152642, and a construction supervisor licence, CS-077387, and shows both as active. Those are the directory's own listings rather than anything confirmed here, so check both numbers with the state before you sign. The same page also carries a Rhode Island residential contractor record, 29032, that it labels "License Not Verified" while printing it as active and simultaneously giving it a November 2010 expiry date — treat that one as unreliable in either direction and ask directly if the answer matters to you. The honest bottom line: real permitted work at real budgets, concentrated south and west of Boston, with nothing written by a past client to go on. If the project is a large addition or a whole-floor renovation, this is a plausible firm to get into a bidding set. Ask for two or three recent homeowner references you can actually call, current insurance certificates, and the licence status straight from the state.
