KMD Plumbing

KMD Plumbing describes itself as a family-owned plumbing and heating company based in Dennis, Massachusetts, serving customers across Cape Cod. State registry records show the business's Massachusetts Master Plumber license, 16532-PL-M, active and held by Kevin Decoteau — the same name customers across a decade of reviews credit for their work. The company's self-reported tenure varies by platform: its own website claims over 25 years of experience, while a directory profile for the same business lists 17. Reviewers from 2012 through 2026 consistently credit Kevin, and a colleague named Collin, for prompt, courteous and technically sound work. The specific jobs described include gas piping and gas-appliance reconnections, faucet and fixture leak repairs, water heater installations (including a same-day emergency replacement for a rental property), and gas boiler and radiator heating system work — most notably an $8,000 replacement of a 50-year-old boiler with an added heating zone. Several homeowners say a first job went well enough that they now use KMD as their regular plumbing and heating contact, and pricing is described as matching quoted estimates. Before booking, it's worth asking directly about emergency service: the company's own website advertises "Emergency Service Available," but a directory FAQ for the same business states it does not offer emergency services, so callers should confirm current after-hours availability rather than assume it. A December 2023 review alleges the crew drained a home's antifreeze without approval during winterization, costing the homeowner over $1,200 to replace; the business responded publicly that the reviewer is not one of their customers and that they never performed the described work, so it isn't clear which account is accurate. A separate, more minor 2020 review noted a late arrival on an otherwise satisfactory small job. Overall, KMD Plumbing looks like a solid, long-running local choice for gas piping, water heater and boiler work on Cape Cod, run by a licensed plumber whose name repeat customers know directly — worth a quick call to confirm emergency-service hours and current scheduling before booking.
