Meet the Team
Gary
Owner & Plumber
Gary has worked in the plumbing trade for my whole life, and most of his. He first learned how to plumb from his father, making him a second generation plumber. He then widened his scope, taking on remodeling jobs as well. He first went independent in Ohio, when his wife convinced him to make the jump. They moved to Arizona in '91, and Gary spent some time learning the market and forming relationships before going independent again.
Alex
Owner & Plumber
I have been in the trade full time since 2021, but Gary has brought me along to jobsites here and there since I was growing up. I am honored and privileged to learn the trade from him, making me a 3rd generation plumber.
HOW WE WORK
The Diagnostic Difference
Our name isn’t just a brand. It’s how we work.
The majority of our clients’ plumbing issues are straightforward, and with our experience and intuition we’re able to take care of the issue quickly and cleanly. But sometimes there is a bigger underlying issue. Before we recommend a fix, we find the root cause. That might mean a sewer camera inspection to see what’s actually in your drains. It might mean using locator services before recommending a full repipe. Whatever the situation, we want to understand it fully before we quote it.
We also believe in explaining what we find and giving you options. You’ll never get a vague answer and an invoice from us. We’ll show you what’s going on, tell you what it means, and help you make a smart decision — whether that’s a repair, a replacement, or a “let’s watch it for now.”
What that looks like in practice:
- We use sewer cameras to inspect stubborn drain lines. Different kinds of blockage and damage require different solutions.
- When advantageous, we utilize high-speed drain cleaning that cleans the full pipe interior rather than punching a hole through the clog
- We use water contaminate lab test data, and we can consult you on building the right kind of water filtration system for the kinds of impurities you’re trying to remove, whether it’s a simple water softener or a more thorough whole home filtration system.
- We walk you through repipe options (copper vs. PEX, cost, pros/cons) before you commit
- As your general contractor, we plan and coordinate across multiple trades to build your next exciting project
We use modern equipment and technologies when they produce better results and longer-lasting fixes.
