What we handle
Fourteen jobs, most of them same day.
Residential and light commercial across San Antonio. If it moves water or gas through your building, it's on this list.
01
Emergency response
Burst supply lines, failed water heaters, and active leaks. Short-notice calls taken seven days a week.
02
Drain clearing
Kitchen, bath, and main lines opened by cable or hydro jet, chosen by what actually caused the stoppage.
03
Sewer camera inspection
A camera down the line before anyone digs. You see what we see, and the repair plan matches the footage.
04
Sewer repair & replacement
Root intrusion, bellied sections, and collapsed clay pipe. Spot repairs where they hold, full runs where they don't.
05
Water heater replacement
No hot water, rusty water, or a unit past its service life. Straight swap or an upgrade, your call.
06
Tankless installation
Install, descale, and repair. Worth the conversation if your household runs out of hot water by the third shower.
07
Slab leak location
Warm floor spots, a meter that spins with everything off, a bill that jumped. We find it before opening concrete.
08
Whole-home repipe
Failing galvanized and polybutylene replaced in PEX or copper, sequenced to keep your water on where possible.
09
Water softeners
Local water is hard enough to scale a heater and shorten every appliance in the house. Install and service.
10
Pressure regulators
City pressure above 80 psi kills fixtures and valves early. We test it and replace the regulator when it's failed.
11
Gas line work
New runs, appliance connections, leak testing, and pressure inspections. Permitted where the city requires it.
12
Fixtures & valves
Running toilets, dripping faucets, seized angle stops, and leaking supply lines. Small jobs done right.
13
Outdoor spigots
Split hose bibs, leaking vacuum breakers, and yard line repairs. The stuff you notice when you drag out the hose.
14
Freeze damage
Cracked pipe and burst bibs after a hard freeze, plus insulation and shut-off work before the next one arrives.
Why us
No hourly meter. No mystery invoice.
The complaints people have about plumbers are always the same three things. Here is how we handle each one.
You approve the number first
We diagnose, quote the job flat, and wait. If you say no, you owe nothing beyond the trip and we part on good terms.
You see the problem
Camera footage, a photo of the failed part, the reading off the gauge. We show you why the repair costs what it costs.
We come back if it fails
Every repair carries a workmanship guarantee. If what we fixed fails on us, we return and make it right.
Licensed and insured
Proper state licensing and full liability coverage. Ask for the paperwork and you'll have it the same day.
We pull the permit
Water heaters, gas lines, and sewer work get permitted where the city requires it. That protects your resale, not just us.
We leave it clean
Drop cloths, shoe covers, debris hauled out. You should not be able to tell where we worked except that it works.
About us
Straight answers, fair number, done once.
Most people call a plumber maybe twice a decade, usually on the worst day of their week. That puts you at an information disadvantage, and plenty of outfits in this trade are happy to work that angle.
We would rather be the number you keep in your phone. That means explaining what failed in language that makes sense, quoting the work before we start it, and not inventing a second problem while we're under the sink.
We cover San Antonio and the surrounding communities, on everything from a seized shut-off valve to a full sewer replacement. Residential and light commercial.
- Flat quote approved before work begins
- Licensed, insured, and permitted
- Camera and photo evidence on request
- Short-notice and evening calls taken
- Workmanship guarantee on every repair
- Clean site, every visit
A leak costs more every hour it runs.
Shut the supply off if you can reach the valve, then call. We take short-notice work seven days a week until 11 PM.
