A Family Tradition of Plumbing Excellence

Built on Experience, Fueled by Integrity

At Cosentino Plumbing, our story begins decades ago—not in a boardroom, but under kitchen sinks and in muddy trenches. Richard Cosentino started plumbing at just 16 years old, learning the trade the old-fashioned way: by showing up, listening, and getting his hands dirty. What began as a teenager’s job quickly turned into a lifelong career, fueled by a passion for craftsmanship and a deep respect for homeowners who just want their plumbing done right.

Today, Richard leads Cosentino Plumbing with that same commitment to honest work, reliable service, and lasting solutions. We’re not part of a franchise. We don’t read off a script. We’re a small team that treats every job—and every homeowner—with genuine care.

Plumbing Isn’t Just a Trade—It’s Our Calling

We don’t believe in shortcuts. That’s not how we were raised, and it’s not how we work. Every repair, every install, and every inspection we do is handled with the care of a master tradesperson and the heart of a neighbor. Whether we’re replacing a water heater or unclogging a sewer line, we take pride in being the kind of company people feel comfortable inviting into their home.

Our business is built on relationships. Many of our clients have been with us for years. Some have even watched Richard’s own family grow over the decades, just as he’s helped their homes stay functional and safe. That’s what makes this job worth doing—and why we keep showing up with the same pride and energy every day.

Local Service, Personal Attention

We’re proud to live and work in the same communities we serve. Based in Eastvale, Cosentino Plumbing provides residential service throughout a 25-mile radius—covering neighborhoods where we’ve made hundreds of house calls and earned the trust of homeowners through consistency and quality.

When you call us, you're not getting an outsourced technician or a rotating cast of workers. You’re getting a small, consistent team that remembers your name and your home. We show up when we say we will, explain your options in plain English, and finish the job without excuses.

What Sets Us Apart

  • No Middlemen, No Corporate Policies

    We don’t answer to investors. That means no quotas, no upsells, and no pressure tactics. We only recommend what’s truly needed, and we explain why—every time.

  • We Specialize in What We Know

    We don’t stretch ourselves thin with commercial contracts or HVAC add-ons. We focus exclusively on residential plumbing, sewer lines, drains, water heaters, and filtration—because that’s what we’re best at.

  • You’ll Always Know Who’s Coming to Your Door

    Forget call centers and anonymous workers. Our clients deal directly with Richard or a familiar team member who’s been on the job before. It’s the kind of consistency you can’t find with bigger companies.

  • We’re Built for the Long Haul

    We’ve lasted over three decades because of trust—not tactics. Our goal is to be the plumber you call for the next 20 years, not just the next leak.

A Local Plumbing Company You Can Believe In

At Cosentino Plumbing, we’ve built a reputation for integrity, skill, and consistency—not because it’s flashy, but because it works. We know you have options when it comes to plumbers in Southern California. But if you’re looking for a family-run business that treats your home like their own, you’ve come to the right place.

Thank you for getting to know us. We look forward to serving you.
