About
Serving homes and businesses with skilled plumbing and heating work backed by 20 years of experience.
M&M Precision Plumbing and Heating Corp. was founded in 2018 with a commitment to providing reliable plumbing and heating work for residential and commercial customers. Based in Ronkonkoma, NY, we proudly serve properties throughout Nassau County and Suffolk County while bringing 20 years of industry experience to the work we perform.
Our background covers the everyday systems property owners rely on, from residential plumbing and commercial plumbing to emergency repairs, drains, water heaters, boilers, and heating equipment. Having plumbing and heating capabilities under one roof gives our customers one local resource for many of the systems that keep their properties running.
Reliability has remained central to how we work. We believe customers deserve clear communication, upfront pricing, and service from a licensed, insured, and bonded team. Whether we are responding to an urgent plumbing issue, maintaining a heating system, or planning equipment replacement, we focus on understanding the problem and helping customers make informed decisions about the next step.
Our connection to Long Island is an important part of our story. We have proudly served Nassau County and Suffolk County for 20 years, working with homeowners, businesses, property managers, and other commercial customers across a large service area.
We also understand that plumbing and heating work can create unexpected expenses. Financing is available, and we accept cash, check, and credit cards. Free estimates are available as part of our service process, and customers can ask about military and senior citizen discounts.
Our goal is straightforward: provide reliable plumbing and heating work that customers can feel comfortable calling on again when their property needs attention.
