FAMILY-OWNED TX MASTER PLUMBER
The crew behind the call.
Joey Walsh and a small team of licensed plumbers, looking after Austin since 2010.

How we got here
Plumber Down Under was started in 2010 by Joey Walsh, a master plumber who got tired of watching Austin homeowners get burned by hourly rates, vague “diagnostic fees,” and salespeople in plumber’s clothing. The pitch was simple: real licensed plumbers, flat rates, on time, every time. 15+ years and a few thousand happy neighbors later, the pitch hasn’t changed.
What we believe
A plumber should be the easiest tradesman you ever hire. We answer the phone in person, we show up in the window we promised, we walk you through the fix before we touch a wrench, and we leave the place cleaner than we found it. If we make a mistake, we own it on the spot. That’s it. That’s the playbook.
Who works on your home
Every technician on our crew is a licensed TX plumber, background-checked, drug-tested, and trained on the latest code (TX Plumbing Code, IPC 2021). We don’t use subcontractors. The truck that pulls up to your house is ours, and the person who steps out of it is on our payroll.
The Down Under Code
Four Promises We Make Every Visit
These aren't slogans. They're the rules every Plumber Down Under technician signs on day one. If we ever break the code on your job, the work is on us.
Show Up
Show up when we said we'd show up. We give you a 2-hour window, then we hit it. If we miss it, the trip charge is on us.
Square Deal
Square pricing. No back-of-truck markups. Flat-rate quotes before the wrench comes out. What you sign is what you pay.
Take the Bin
Leave it cleaner than we found it. Drop cloths, shoe covers, the trash leaves with us. Your floors won't know we were there.
Own the Fix
If we break it, we own it. On the spot. Two-year workmanship warranty on every repair. One call to make it right.
