Precision Plumbing & HVAC is a Methuen, MA plumbing and HVAC company organized around one name that turns up in nearly every review: Marcin. HomeAdvisor and Angi both currently show a perfect 5.0 stars from 23 ratings apiece, and the reviews behind those numbers describe a small, hands-on operation — an apprentice named Carlos and a helper named Jamie appear alongside Marcin on different jobs, not a fleet of trucks. The bulk of what's described is plumbing. In a March 2023 review, a customer had an old hot water tank swapped for a tankless system and called the communication quick. Earlier reviews describe bigger jobs — a 2022 account of cracked cast-iron waste lines found mid-project, with Marcin coordinating an exterior water-and-sewer-line replacement alongside another contractor, and a 2021 review of a full re-pipe across two remodeled bathrooms: a new shower, tub, two toilets, two sinks. Other 2021 reviews mention running a gas line to a kitchen for a new stove and installing nat-gas piping for a backyard grill. The HVAC side of the business is documented too: a 2021 review describes a central air system installed by Marcin and two associates, a 2020 review mentions converting a furnace from oil to gas, and another 2021 review from a customer who first hired the crew for a gutted bathroom renovation says they came back to have an old gas water heater and furnace replaced with a high-efficiency combi boiler. An interior designer's 2020 review says she has used the crew on multiple client bathroom remodels as well as her own home addition and calls them consistently reliable. One 2020 review stands out for responsiveness rather than scale: a customer who cracked a toilet tank on a Saturday reached out expecting to wait until Monday, but Marcin emailed back that same weekend, rearranged his schedule to come out Monday, and walked the customer through which replacement toilet to buy before finishing the job with parts already on hand. Its written record on file runs from December 2019 to March 2023, while both platforms currently display that same 5.0-star line today. The company's Massachusetts plumbing license is active on the state registry. It's a reasonable call for a plumbing overhaul, a water heater swap, or a furnace or AC installation in the Methuen area.
Marcin was very professional and attentive. He was great at communicating and was very quick to respond. They removed an old hot water tank and installed the new tankless system. I would highly recommend his services. Looking forward to working with them again in the future!
Marcin and team did a great job redoing the plumbing in my entire house. We also discovered cracks in our waste line and he replaced all of the original cast iron lines in the basement and coordinated with the contractor who replaced our exterior water and sewer lines unexpectedly. He was quick to respond to questions and requests, very reliable, and did a great job plumbing 2.5 bathrooms, laundry, and kitchen.
Marcin and his team did a great job with a big and complicated plumbing project. They redid the plumbing in a whole side of our house because we had a lot of leaks and were remodeling 2 bathrooms. They installed a shower, a tub, two toilets, two sinks, and a lot of other plumbing to improve the whole system. Marcin knows what he is doing and was good to work with throughout. We would recommend Precision and Marcin for any plumbing project!
Marcin and Jamie stand out not just based on the quality of the work, which was fantastic, but also because of their professionalism. We have worked with a lot of subs over these last 5 months and Marcin really, really stood out. He ALWAYS showed up on days when he said he would. He set and communicated expectations very well. I can't state enough how much these aspects of customer service contributed to my stressing his professionalism. His skill and knowledge were, of course, stellar but all the subs have done very good work, when they showed up.
