New Reasonable price | $2,000+ I was really impressed by how thorough and careful the team was during the entire process. They handled everything with such professionalism and were always friendly and polite when answering my questions. It felt like they genuinely cared about getting things right and even took extra steps to make sure I was satisfied. I will continue to use M&M for any plumbing services needed at my home. Thanks Max! Services Service not listed

New Great price | $1,200–1,400 5 Stars — Exceptional Service, Integrity, and Workmanship I cannot say enough good things about M&M Precision Plumbing & Heating. After nearly a week without reliable hot water and four unsuccessful service visits from another company, I was exhausted, frustrated, and losing confidence that anyone would actually resolve the problem. M&M completely changed that experience. From the moment Max arrived, the difference was remarkable. He listened to my concerns, took the time to understand the history, and actually diagnosed the system rather than immediately suggesting another replacement part. What impressed me most was that when I offered to leave him alone to work, he invited me to stay and watch the diagnostic process. He explained what he was checking, what he was finding, and the possible causes without ever making me feel like my questions were an inconvenience. Max was knowledgeable, thorough, and honest. He identified concerns with previously installed components, explained the circulation problems, and discussed different possibilities before recommending a repair. He even offered to document his findings so I could take them back to the previous company rather than feeling pressured to hire M&M. That level of honesty and integrity earned my trust. When repair day came, Zack and Kyle arrived ahead of Max and immediately got to work. Kyle had everything organized and prepared, and Zack went out of his way to protect my property, carrying bucket after bucket of dirty water outside rather than dumping it into my landscaping. When Max arrived, the teamwork was outstanding. They replaced the necessary components and piping, thoroughly flushed years of heavy buildup from the system, and continued testing until everything was operating correctly. They didn’t simply feel a hot pipe and declare the job finished. They made absolutely sure the hot water was consistent, the system completed its heating cycle properly, and the work was done right. In approximately three hours of repair work, M&M accomplished what the previous company had failed to resolve over four visits. I’ve lived in this home for eight years, and the hot water has genuinely never performed better. The workmanship is excellent, the piping looks fantastic, and they left the work area clean. Beyond their technical abilities, Max, Zack, and Kyle were friendly, respectful, upbeat, approachable, and genuinely enjoyable to have working in my home. Not once did they make me feel intrusive or uncomfortable asking questions. Their confidence came from knowing their trade and demonstrating it through their work. M&M didn’t just restore my hot water — they restored my confidence that there are still companies that take genuine pride in their workmanship, treat customers with respect, and stand behind what they do. Thank you, Max, Zack, Kyle, and everyone at M&M Precision. You earned every one of these five stars, and I cannot recommend you highly enough. - Paul S. Services Water heater repair

Michael Amore 5 of 5

Reasonable price | $2,000+ M&M Precision Plumbing And Heating Corp. is a great business and a valuable resource to the community. At the recommendation of a master plumber who does not service my area, I initially retained M&M to perform routine maintenance of my gas boiler, which Russ handled expertly. But a couple of weeks later, the main water line from the curb stop to my house sprung a leak and required complete replacement. This is a major job that can take weeks. M&M had the job done and water restored to my house within days of my acceptance of M&M’s estimate. Everyone at M&M is a pleasure to work with. Owner Max is totally involved, highly accessible, and is deeply committed to maximum customer service. The firm even uses an AI tool that is virtually impossible to tell from the real thing, ensuring 24-hour interactive service. Judy, who runs the office is an absolute pleasure to work with. Knowledgeable and caring. Can’t go wrong with this great plumbing concern. Services Outdoor plumbing system repair

Douglas Haber 3 of 5

I called M&M Precision for what I understood to be an estimate visit for boiler work. The crew was professional, the estimate seemed fair, and everyone I dealt with was pleasant. However, after the visit I received a $161.85 invoice labeled as a “trip fee” / diagnostic charge. No fee was mentioned when scheduling the appointment, and the company website clearly says: “Contact us today for a free estimate.” When I called afterward, I was told the “free estimate” wording only applies to new systems, but that distinction was never explained beforehand and is not clear from the website. Not disputing their right to charge trip fees, but the lack of upfront disclosure was disappointing.

Business reply

M&M Precision Plumbing And Heating Corp

Hi Douglas, thank you for sharing your feedback. We’re glad to hear our team was professional and that the estimate felt fair during your visit. We sincerely apologize for the confusion regarding the trip/diagnostic fee and any lack of clarity about how the “free estimate” wording applies to new systems versus service visits. We value transparency and appreciate you bringing this to our attention. Our goal is to ensure customers understand any potential fees upfront, and we’ll review our website and scheduling communications to make this distinction clearer. We hope this experience won’t deter you from reaching out in the future for any plumbing or heating needs.

Great price Just used M&M Precision to replace my old boiler and hot water heater and I could not recommend them enough. From start to finish, the experience was excellent.

Very professional and trustworthy. If you’re in need of a boiler replacement, look no further.

As a homeowner, it is very hard for me to trust plumbers because they come up with random numbers, excuses and reasons to increase your quote. However, I trust this company with all my heart, and I do not hesitate in calling them when I need them for a job. No longer do I call 3 different plumbers from 3 different companies to seek a quote. This company is my go to because of their honesty when it comes to the job and their transparency. The workers are ALWAYS excellent when delivering customer service, and are never rude when I have questions or concerns. Thank you Joe Gallapoli for the recent job he did at my house and for explaining the issue with patience and understanding. If you are just like me who is uneasy about other companies, give M&M Heating and Plumbing Corp a try.

Max answered all my questions about the job, and thoroughly explained our options for the fix. Happy to say thanks to Max at M&M, we now have hot water again. We just recommended him to a friend in town, and he promptly paid her a call to diagnose the issue.
