Find a Plumber in Massachusetts

Massachusetts credentials plumbers through the Board of State Examiners of Plumbers and Gas Fitters: apprentice registration, journeyman, master, plus gas fitter tiers. Plumbing work at your home must be done by a journeyman or master examined by the Board, with the proper local permit; minor repairs like a leaky faucet or blocked drain need no permit.

• License structure. apprentice (registration) / journeyman plumber / master plumber (plus journeyman and master gas fitter and LP installer licenses)
• Worth knowing. Only a master or journeyman plumber examined and issued a license by the Board, with the proper permit issued by the local plumbing inspector, can perform plumbing work at your home or business, though minor repairs such as fixing a leaky faucet or clearing a blocked drain do not require a permit.

Massachusetts winters are the hard-freeze kind: deep frost, burst risk, and a real case for insulating pipes in unheated basements and exterior walls. The water side is friendlier. Boston's MWRA supply tests around 16 mg/L, about 1 gpg, solidly soft per MWRA quality reports, so scale buildup is far less of a concern than freeze damage in much of the state.
