Verified record
Dargon Plumbing and Heating is listed by BBB at 48 Hancock St in Watertown, Massachusetts. The company site uses the name Dargon Plumbing, LLC and describes plumbing work for builders and general contractors across Greater Boston. It lists Master Plumber #16384 and Plumbing Corporation #4165 as its own license claims. The current material offers little customer-review history to assess. The BBB profile categorizes the Watertown business as a plumber, and a separate directory result lists a Dargon Plumbing and Heating, LLC in Arlington. The company site does not give a street address, so the Watertown listing is the clearest current location anchor. A BuildZoom page for R. M. Dargon plumbing in Jamaica Plain carries a different address and phone and lists plumbing and heating license #12854 as inactive. That profile is not clearly the same business as the Watertown listing, so its licence status should not be assigned to this company without confirmation. Before booking, ask whether Dargon takes homeowner projects as well as builder work and confirm the license details for the contracting entity on your job.
