JMS Plumbing and Heating LLC

JMS Plumbing and Heating is a family-owned plumbing and heating company based in Merrimack, NH, serving Merrimack, Amherst, Nashua, Derry and Manchester. The company's own site describes itself as family-owned, offering plumbing, heating, gas-line and bathroom services with free estimates. Customers who have hired JMS consistently describe fast, responsive scheduling and transparent, upfront pricing explained before work begins. Across 54 reviews from 2021 through 2026 on Google, HomeAdvisor and Angi, reviewers repeatedly praise Jay for arriving on time, explaining the job and cost clearly, and leaving a clean work area — from water heater replacements and a leaking pipe repair at the water main to garbage disposal installs, faucet swaps and a full bathroom remodel with two new bathtubs. In the last six months alone, reviews were logged with no negative feedback, and the business holds an active New Hampshire plumber license (MBE2401680), registry-verified under its own name. Two dated complaints are worth knowing about before booking: a 2022 review alleged being overcharged roughly $2,250 on a water heater job, and a 2021 review described unclear communication about the scope of a repair. Both predate the bulk of the company's recent, uniformly positive record and have not recurred since. Worth confirming directly: the company's own website currently displays a notice that it is temporarily closed due to medical reasons, even though its Google reviews continue as recently as mid-2026 — a homeowner reaching out now should confirm current availability rather than assume a normal response time. For straightforward plumbing repairs, water heater work and small bathroom fixture jobs in the Merrimack/Nashua area, JMS has built a long, well-documented track record of satisfied customers and a verified license — worth a call to confirm scheduling given the current closure notice.
