Sam Sean Plumbing and Heating, LLC

139 Google ratings averaging 4.9, and many of the calls customers describe couldn't wait: no heat in a cold snap, lost water pressure on a Saturday night, a cracked boiler leaking carbon monoxide. Sam Sean Plumbing and Heating describes itself as a family business with over 19 years in plumbing and heating, working from Boston out through Lowell, Andover, Chelmsford and the towns around them. Its Massachusetts plumber licence (9628360-PL-C) is active on the state registry. The emergency stories are specific. In a September 2022 review, a customer who had tried more than five plumbers said Sam came Sunday morning, within an hour of reaching out to them. In an August 2022 review, a customer said Sam was on site within an hour on a 95-degree afternoon and had a shower, two sinks and a toilet sorted in a few hours. A January 2025 reviewer described the team working day and night when the family had no heat. Bigger jobs show up too. A January 2024 review describes the crew removing an old cast-iron main and redoing the plumbing for two bathrooms and a kitchen, after other plumbers would not quote the job. In a June 2025 review, a customer described a full switch from copper to PEX. Boiler and tankless water heater installs recur: a December 2022 customer had a cracked, decades-old steam boiler replaced, and a March 2023 customer said the plumber and his brother pulled the permits and secured a $550 Mass Save rebate on a tankless unit. Customers in 2024 and 2025 also name a technician, Connor. The $95 visit fee drew a complaint. In a November 2024 review, a customer paid it for a five-minute visit that ended with advice to improve ventilation around their well tank, and advised others to ask about the visit cost first; a March 2025 customer paid the same $95 diagnosis fee and said it had been made clear up front. A December 2024 reviewer left one star and the words "Not recommended!"
