John L Coombs

156 permits and not one review. John L Coombs works out of Milton, and the only thing written down about him is a permit trail — but it is a long one, and it says something clear about the work. Read the filings and the label on the profile makes sense: this is gas and plumbing work, not remodeling. The sampled permits are dominated by gas-fitter jobs — setting 120- and 500-gallon propane tanks, trenching underground supply lines from tank to house, tying into a plumber's stub — filed across Burlington, Marblehead and Manchester, with a handful of Milton jobs of a different kind: a 2022 second-floor guest bathroom with new fixtures and vanity, a 2022 kitchen with new cabinets and countertop, a 2020 basement perimeter framing. BuildZoom counts 39 permits in the last three years, 28 of them in 2023, so the shop is active. On licensing, BuildZoom says it confirmed Massachusetts construction supervisor licence CS-050957 as active in June 2026 — that is the directory's own check, not a registry verification, so confirm the number with the Department of Public Safety yourself. The same profile shows home improvement contractor registration 127067 as inactive, which matters if you are hiring him for nonstructural residential remodeling rather than gas or plumbing work. Nobody has written publicly about how a job with him went. If the work you need is a propane tank, a gas line or a plumbing tie-in, the permit history is directly on point; for a kitchen or bath remodel it is thinner. Ask for recent references, current HIC registration if the job is a home improvement, and proof of insurance.
