When we first spoke with the team at Flow Masters Plumbing, we could immediately tell they were different. In a field that’s often plagued by temporary fixes and no-shows, Flow Masters is all about doing the job right—and building relationships that last.
Founded in 2011 by Alan Moran and Fergal McMahon, Flow Masters set out to raise the bar for plumbing in the Bay Area. From the very beginning, they’ve focused on long-term solutions over quick patches, and that mindset has earned them serious trust among homeowners, architects, and now, an increasing number of property managers and real estate companies.
In 2025, they’re expanding—and we’re proud to welcome them as a Preferred Vendor on Property Atlas.
Today, Flow Masters has a team of 20 and plans to grow to 30 by the end of Q3. And while they’re scaling up, they’re doing it without compromising on the quality or care that built their reputation in the first place.
Their list of services runs deep—everything from: general plumbing maintenance and drain cleaning to radiant floor heating systems, water filtration, leak detection, and fire sprinkler inspections. Whether it’s an emergency repair or a full-system upgrade, they’re the ones you want on-site when it matters.
In fact, their work was recognized at the San Francisco Decorator Showcase House in 2020, one of the highest compliments in the field—and a testament to the craftsmanship and attention to detail they bring to every project.
What we especially appreciate is how much of their business comes from referrals and repeat clients. That only happens when people feel confident recommending you—and Flow Masters has clearly earned that confidence.
“We built this company with the belief that plumbing is more than pipes and fittings—it’s about people,” says Fergal. “We want our clients to feel like they have an advocate, not just a vendor.”
So whether you’re managing a portfolio of buildings or just need someone you can count on for tough jobs and fast turnarounds, Flow Masters Plumbing is the kind of team that shows up—and follows through.
