D Larsen Plumbing & Heating

Four problems in one visit, handled inside an hour — that 2022 Google review is the most concrete thing written about D Larsen Plumbing & Heating, and it captures what people call this Marshfield shop for. A stopped-up toilet, two leaking outdoor valves, and a badly corroded line to the boiler: two men split the work and left it clean. The company has been at it a while. Its BBB profile puts the start date at January 1996 — thirty years — names David Larsen as owner with three employees behind him, and grades it A+, though it is not BBB accredited. The written history is thinner than that tenure suggests. Google shows 4.6 stars across 10 ratings, and only three reviews are on file, running 2022 to 2024. They point the same direction: a 2024 reviewer called the crew responsive and thorough, the work timely, the rates honest; a 2022 customer put it more bluntly — "knows his trade." Word of mouth agrees. On Nextdoor in March 2025, a Cohasset neighbor wrote that they use "David Larson Plumbing and Heating of Marshfield," describing someone who comes on time, fixes what's needed, and cleans up after. Before calling, know what you're working with: a three-person shop whose newest written review dates to 2024. Nothing negative turns up anywhere, but that is a short paper trail for a business three decades old, so ask for a couple of recent local references and get the scope in writing. For routine repair and replacement work — the drain, the valve, the boiler supply line — he's a reasonable call, particularly if a tidy worksite is what you care about.
