Black Onyx Group works out of Middleton, and the story that keeps repeating in its reviews is speed on the worst kind of call: a water heater failing in the early morning, fixed and hauled away within about an hour. The company says it's run by Igor, a licensed master plumber with 25 years in the trade, alongside master plumber Edin, doing plumbing, gas, and HVAC work across the Boston area for both homeowners and multi-unit buildings. Since March 2026 the same details turn up across reviews from both individual homeowners and multifamily property managers: quick dispatch on water heater emergencies, technicians who explain the problem before fixing it, and property managers naming Black Onyx their standing vendor rather than a one-time call. That pattern sits on top of a two-year run of reviews dating to 2024 — 22 in total across Google and other sources, with Google alone showing 4.9 stars from 23 ratings — and a building-permit record showing 24 Boston permits filed since 2023 with every rated one closed out. The one flat note is a May 2026 review knocking the company down to 2 stars over a company van tailgating aggressively on the highway — not a complaint about the plumbing or HVAC work itself, but worth being aware of. The review count, while consistent, is still modest for the volume of repeat commercial work described, so there's less of a sample to lean on than the star average alone suggests. For a burst pipe, a dead water heater, or an HVAC issue that can't wait, Black Onyx looks like a solid call, especially for anyone managing more than one property who wants a single vendor for both trades. Worth confirming directly: current response times for your area and whether emergency dispatch covers your specific type of building.

Their van tailgated me aggressively on the highway.

Had a great experience with Black Onyx. Junior and his team were professional, knowledgeable, and very easy to work with.<br>They arrived on time, clearly explained the issue and the work needed, and handled everything efficiently. What stood out most was their attention to detail and how clean they kept the space throughout the job.<br>Overall, a smooth and stress-free experience. I’d definitely recommend Black Onyx and wouldn’t hesitate to use them again. ( Dalibor )

Black Onyx was a life saver! I had an emergency at my business and could not operate fully. Not only did they get me up and running same day the price was very reasonable. Thank you to the whole team!
