Mark J Cullen Plumbing Co. is the Norwood plumbing shop homeowners call for repairs, replacements, and urgent leaks. Recent customers describe quick callbacks and technicians who arrive when promised; one 2026 customer had used the company for a water heater, garbage disposal, and kitchen faucet replacement and praised the quality of the work and the crew's care for the home. The company holds an active Massachusetts plumber license in the state registry. The strongest part of the customer history is its practical range. Reviews describe leak diagnosis behind a kitchen wall, toilet clearing, shower valve work, bathroom vanity and faucet installation, and several repair visits. A 2024 review describes an immediate response to basement water and a clean, efficient vanity installation; a 2023 customer likewise reported a prompt fix to a concealed leaky pipe at a fair price. Across 15 Google reviews from 2021 through February 2026, customers repeatedly mention responsiveness, punctual arrivals, neat work, clear explanations, and repairs that solved the problem. There is also a long-standing relationship in the older reviews: a 2021 homeowner said Cullen had handled many jobs over 20 years, including a Grohe shower valve and blocked toilets. A 2022 review describes the company restoring heat and hot water by the customer's return from work after a 7 a.m. callback. Those accounts are dated, but they show the kinds of urgent and small plumbing jobs customers have brought to the company. Mark J Cullen looks suited to homeowners who need responsive residential plumbing help, from emergency leaks to fixture and water-heater work. Before booking, confirm the exact scope and whether a heating or hot-water issue is being handled as plumbing service; the written reviews establish those jobs but do not define a separate HVAC offering.

Mark and his crew are first rate. Mark was very responsive when I left messages, his prices were very reasonable, his crew shows up on time (actually early), they are very pleasant, protected my property while they worked, cleaned up after, etc.
Mark Cullen and his staff are terrific. Very knowledgeable, neat workers and they clean up after themselves. I have had Mark do many things for me over 20 years, including fixing a Grohe shower value to clearing toilets etc. He is always happy to help and reasonably priced. Punctual too. Nice work Mark.
