(210) 905-4380Veteran-owned, locally operated precision plumbing for San Antonio. No slick salesmen, no cheap "big-box" parts. Just honest work, upfront pricing, and unwavering integrity.
The parts you find at a big-box home supply store are NOT the same parts that o5 Plumbing uses. Big plumbing equipment manufacturers typically stock big-box stores with lower-end parts. At o5, we source our parts from plumbing supply companies that stock equipment that may look similar to big-box store products, but is longer-lasting, better quality, and often comes with limited lifetime warranties.
That's why we use only professional-grade materials on your plumbing job.
Our technicians treat you and your home with respect and care. We use personal protective equipment such as shoe covers and drop cloths to protect your home, and clean up after every job.
The O5 Standard
Most plumbing companies run the same playbook: show up late, quote high, use whatever parts are on the truck. We built O5 around the stuff that kept bugging us as homeowners ourselves.
We diagnose first, then hand you a flat-rate quote with the full scope written out. No hourly billing that creeps up, no "well, while we're in here..." surprises. You approve the number or we pack up. Your call.
The faucet cartridge at Home Depot and the one we install may look identical. They're not. We source from plumbing supply houses that stock the manufacturer's pro line, with thicker brass, tighter tolerances, and warranties that actually hold up.
We've been in enough homes to know: the mess bothers people more than the leak sometimes. Our guys cover floors, protect walls, and leave your space cleaner than they found it. That's the baseline, not a bonus.
No bait-and-switch with a "senior estimator" who hands you off to a junior crew. The licensed plumber who walks through your door is the same person turning wrenches. They can answer your questions because they're the ones doing the job.
You get a specific window, a heads-up call when we're 20 minutes out, and a text with your technician's name and photo before they knock. We know you've got better things to do than sit around waiting.
Our workmanship guarantee means exactly what it says. If something we installed or repaired doesn't hold, we come back and make it right at no charge. No fine print. No "well, that's normal wear and tear" runaround.
Customer Reviews
"I chose o5 Plumbing because they are Military Vets, as I am, and the reviews were great. Adam was my service guy and he did an excellent job in a small amount of time. Plus he gave me some great advice about things I didn't know. I will definitely call o5 Plumbing for all future repairs or projects!"

"Adam installed our RO system, and we couldn't be happier with the experience. He was extremely friendly, took the time to explain everything in detail, and did the work very thoroughly. His pricing was very reasonable. Highly recommend o5 Plumbing."

Stone Oak • Reverse Osmosis Install
"On time, professional, and respectful of our home. Walked me through every step of the diagnosis before quoting a price — no pressure, no upsell. The repair has held up perfectly. Will use o5 Plumbing for everything from now on."
Roberto Vasquez
Schertz • Leak Detection & Repair
"Eric and his team installed our new water softener and tankless. They explained the sizing for our house, gave a straight number, and stuck to it. The workmanship is excellent — you can tell they take pride in it. Veteran-owned, local, and honest."
Nancy B.
Garden Ridge • Tankless & Softener
"Quick response on a Sunday morning when our water heater went out. They had a tech at the house within a couple of hours, replaced the unit, tested everything, and walked me through the warranty. Fair price for weekend work — couldn't ask for more."
Steve Palmos
Cibolo • Water Heater Replacement
"The thing that stood out was the shoe covers and drop cloths. Sounds small, but after dealing with a plumber last year who left muddy boot prints across my tile, it meant a lot. Great work on the garbage disposal too — quick, clean, and exactly the quoted price."
