## The honest read

Janca Plumbing & Heating is a Weymouth, Massachusetts plumbing and heating company, owner-operated by Emelser Janca, that homeowners across the South Shore hire for water heater work, boiler and radiant heating, gas and piping, pipe repair, and plumbing tied to bathroom and kitchen projects.

Twenty-six Google reviews from 2025 into 2026, all five stars, describe a company that responds quickly and finishes the job. One homeowner called Janca the same day their water heater broke, and the technician also found and had National Grid fix a gas leak while he was there. Another needed two separate fixes inside a month, a leaking water heater and, weeks later, a bathtub leaking into the kitchen below, and called Janca both times because they already trusted the work. A third reviewer had a complicated water heater replacement handled in a way they describe as easy despite the difficulty of the job.

Several reviews describe larger jobs: a new bathroom and kitchen plus a half bath, a full bathroom renovation credited to Emelser directly, a tankless water heater installation, a Navien water heater and heating system setup, and a heating system installed alongside a kitchen and bathroom remodel. One reviewer had plumbing work brought up to code for a town inspection that passed without issues. Reviewers repeatedly name Emelser, and a technician referred to across different reviews as Chello, Chelo, or Ciello, for arriving on time, communicating clearly, and cleaning up afterward.

The Massachusetts licensing board lists an active plumber license, 9628670-PL-C, held by Janca Plumbing & Heating LLC, matching the business name on file.

Before booking, it's worth confirming license details directly with Janca or the state board: BuildZoom's page prints a different license number for this contractor and separately claims Massachusetts plumbers don't need a license at all, which is incorrect and conflicts with the registry listing above.

For South Shore homeowners who need a plumber for water heaters, boilers, gas lines, or plumbing work inside a larger bathroom or kitchen renovation, reviewers, from single emergency repairs to owners of multiple properties who call Janca repeatedly, describe a consistently professional, responsive experience.

**Strengths:**
- Water heater work — repeatedly praised across many recent Google reviews
- Fast response — reviewers cite same-day and 24-hour turnarounds
- Licensed — state registry lists an active plumber license under the company name
- Clean, careful work — reviewers note tidy job sites and attention to detail
- Fair pricing — several reviewers call rates reasonable or transparent

**Concerns:**
- License number mismatch — BuildZoom lists a different number than the state registry

**Where sources disagree:**
- BuildZoom's page prints a different license number, 17930, for this business, while the Massachusetts registry lists 9628670-PL-C under the same company name.
- BuildZoom's page also states plumbers do not need a license in Massachusetts, which contradicts state law and its own license number entry.
