About Cowboy Plumbing — Mesa's Trusted Plumbing Company
Meet the Owner
Led by Alonzo Hidalgo
Founder & Master Plumber, Cowboy Plumbing
Cowboy Plumbing is a family-owned plumbing company based in Mesa, Arizona, founded and led by Alonzo Hidalgo. Alonzo brings years of hands-on plumbing expertise to every project — from straightforward repairs to complex slab leak restorations and whole-home re-pipes. He built this company on a premise that is simple but not always common in the trades: that customers deserve to be treated honestly, informed clearly, and served with genuine professionalism.
Alonzo’s approach goes beyond fixing the immediate problem. He believes a good plumber should take the time to explain what caused an issue, what was done to fix it, and how a homeowner can protect their plumbing system going forward. That commitment to customer education is a core part of how Cowboy Plumbing operates on every call.
When you work with Cowboy Plumbing, you’re working with a business where the owner is personally invested in the quality of the work — because his name and his reputation are behind every job we take on in Mesa.
Our Story
Why Cowboy Plumbing Exists
Cowboy Plumbing was founded in Mesa with a clear purpose: to provide the kind of plumbing service that customers in this community genuinely deserve — and that wasn’t always easy to find. Plumbing is an industry where trust matters enormously, and where the gap between a trustworthy company and an untrustworthy one can cost a homeowner hundreds or thousands of dollars.
Alonzo Hidalgo launched Cowboy Plumbing to close that gap. Drawing on years of hands-on industry experience, he set out to build a plumbing company that customers could rely on for honest assessments, fair pricing, and workmanship that stands behind itself. The name reflects that operating philosophy: in the trades, your reputation is built on your word — and we take that as seriously as any commitment can be taken.
Today, Cowboy Plumbing serves residential and commercial customers throughout Mesa and the East Valley, handling everything from same-day emergency repairs to planned installations, water treatment systems, and comprehensive slab leak restorations. Every job, regardless of size, receives the same standard of care.
Our Core Values
The Principles We Work By
Every decision we make — from how we quote a job to how we communicate with a customer — comes back to these foundational values.
Integrity
We tell the truth about what we find, even when it’s not what a customer hoped to hear. We quote fairly, we don’t manufacture urgency, and we never recommend work that isn’t genuinely needed. Integrity isn’t a policy at Cowboy Plumbing — it’s the baseline.
Reliability
If we schedule an appointment, we keep it. If we say we’ll call you back, we call you back. The most consistent complaint customers have about the trades is being let down on reliability — we built Cowboy Plumbing specifically to be the company that doesn’t do that.
Professionalism
Our technicians arrive prepared, communicate clearly, work cleanly, and treat your home with respect. Professionalism shows up in every detail — from how we greet you at the door to how we leave the work site when we’re done.
Qualifications
Licensed, Insured & Fully Qualified
Every technician Cowboy Plumbing sends to your property is fully licensed and insured in the state of Arizona. We maintain all required credentials, carry comprehensive liability coverage, and operate in full compliance with Mesa’s building codes and permit requirements.
We never send unqualified personnel to a customer’s home. The person working on your plumbing system is a trained professional — and you’ll always know who is coming before they arrive.
