Joseph Mark Peacock

Joseph Mark Peacock is a one-name plumbing operation working out of Billerica, and almost everything known about him comes from building permits rather than from customers. BuildZoom's permit trail runs from 2019 through August 2025 and stays tightly in one lane: boiler swaps on Rogers Street in Lowell, a tub-to-accessible-shower conversion in Methuen, a water heater and sink rough-in for a Danvers salon. Small jobs, mostly under $5,000, mostly residential. BuildZoom lists the work as sewer laterals, boiler and water heater work, general plumbing, septic systems, and gas and piping. What is missing is any customer voice at all. BuildZoom has no reviews on file for him, and no other site turned up a rating, so there is nothing here to say how the work landed with the people who paid for it. His BuildZoom score of 90 is calculated from permit activity, not from anyone's experience, and should not be read as a rating. One thing to settle before calling: the licence. BuildZoom shows a Massachusetts plumber licence numbered 17036 and prints it as active, but flags the same record 'License Not Verified' and notes the expiration it last saw was May 2024. That is the directory's own claim, not a confirmation, and the two halves of it disagree. Ask him for the current licence and check it directly against the Commonwealth's Division of Occupational Licensure before any work starts. He is a plausible call for a small, defined plumbing job — a water heater, a boiler, a gas line, a bathroom fixture swap — in the Lowell, Methuen and Billerica corridor. Just go in knowing you would be the first person on record to say how it went, so get the licence, insurance and a written price up front.
