A Staten Island Plumbing Legacy That Runs Deep

At Louis L. Buttermark & Sons Inc., plumbing isn’t just a trade — it’s a family tradition rooted in Staten Island since 1961. The business was founded by Louis L. Buttermark, a man known across the borough for his unmatched work ethic, pride in his craft, and unwavering dedication to doing things the right way. Although Louis L. Buttermark is no longer with us, his values still guide everything the firm does today.


Now run by his three sons, the company continues to serve all five boroughs with the same respect, integrity, and quality that their father built his name on. From local homes in Staten Island to large-scale commercial jobs across NYC, the team carries forward a reputation that took decades to build — and they don’t take that lightly.

Family-Owned, Union-Rooted, & Proudly Local Plumbing Company

As a family-run operation, many of our clients are families we’ve known for generations.  That kind of trust doesn’t happen overnight. It comes from showing up, doing good work, and standing by it.


We’re proud to be licensed, bonded, and fully insured, with three master plumbing licenses on staff. Our hands are in every job — no runaround. Just honest plumbing done by people who care about their customers.
