Greenlight Home Services

Greenlight Home Services is a Sagamore Beach, Massachusetts plumbing company run by Josh — nearly every review names him personally. Its Massachusetts plumbing license is active with the state registry, it holds an A grade with the Better Business Bureau, and its Google page shows a 5-star average across 98 ratings. The reviews describe an unusually wide range of work for a small shop: water heater replacements, a tankless water heater paired with a whole-house filter swap, a backflow valve installation completed the same day, boiler sensor diagnostics, and a frozen forced-hot-water zone rerouted out of the cold. In a 2025 review, one customer described Josh accessing and replacing a cast-iron pipe to a septic tank hidden behind a wall; in a February 2026 review, another described him unfreezing pipes and digging a ditch to replace heat tape in freezing weather after other plumbers had turned the job down. Recent reviewers keep describing the same pattern: a callback the same day, a picture texted ahead of the visit, an estimate given before work starts, and the job finished in one trip. One 2025 review stands out from the rest: a self-described disabled senior said Josh charged $475 to finish a valve repair another plumber had already started after being quoted $350 elsewhere, and felt taken advantage of. It's the one written complaint in an otherwise uniformly positive record, so it's worth asking for a firm price upfront, especially on any job where another contractor is already involved. For plumbing and heating work on the Cape and South Shore — from routine repairs to jobs other plumbers turned down — this is a licensed, well-reviewed operation built around one plumber's name; just get the price confirmed before he starts.
