Emergency Plumber in San Antonio
Armor Pro Services is a locally owned San Antonio emergency plumber, licensed under Texas RMP #36282, triaging active leaks, sewage backups, no-water calls, and gas odors same day across most of Bexar County. The fast version: shut the nearest valve you can reach, and if you smell gas, leave the building first and call CPS Energy at 1-800-870-1760. Then call us at 210-212-7667 and we will tell you what to do next.

What Counts as a Plumbing Emergency in San Antonio
The honest triage test is simple: is water or sewage actively entering your home, is there a gas odor, or do you have no water at all? If yes to any of those, it is a same-day call. If no, it can usually wait for a scheduled slot at a better price. Here is how the four calls we treat as genuine emergencies break down, and the one move to make before you call us.
- Burst or leaking supply line. Shut the fixture valve under the sink or behind the toilet. If you cannot trace the leak, close the main at the meter near the curb. A pinhole leak that reaches drywall roughly doubles its damage every 48 hours and mold follows inside 72, so the shutoff is what keeps a small repair from becoming a water-damage claim.
- Sewer backup. Stop using every water source in the house the moment sewage shows up in a tub, sink, or floor drain. Every flush pushes more of it into your living space through the blocked main lateral. This is the one call we treat as a health emergency.
- No hot water. Not dangerous the way a gas leak is, but disruptive. If the unit is leaking water or you smell gas near it, treat it as urgent. If it simply stopped heating, it is usually same-day when you call before noon rather than a middle-of-the-night scramble.
- Gas smell. People out first, door left open, then from outside call CPS Energy at 1-800-870-1760 to shut the meter. Do not flip switches or test with a flame. We come in only after the utility has secured the line.
About the phrase you may have searched, 24 hour plumber San Antonio: we will be straight with you. Our phones are staffed Monday through Friday, 8 AM to 5 PM, which is when we dispatch same-day inside Loop 1604, with next-day first-call for outlying addresses. After-hours and weekend response may carry a surcharge we quote before we roll, never as a surprise. We will not advertise a round-the-clock dispatch fleet we do not run. What we will do at any hour is help you make the situation safe over the phone and book the first slot that fits. Call 210-212-7667 and we will tell you which category you are actually in.
Emergency Plumber in San Antonio: What to Do in the First 5 Minutes
Call 210-212-7667 and stop the water first. For a fixture leak, close the shutoff valve under the sink or behind the toilet. For a leak you cannot trace, close the main at the meter near the curb or at the house side where the line enters. That single move is what keeps a $400 repair from becoming a $4,000 water-damage claim, because a pinhole leak that reaches drywall roughly doubles its damage every 48 hours and mold follows inside 72. Once the water is off, the emergency is contained and we can quote the actual fix calmly instead of you bailing water while we talk. We run routes across Bexar County every weekday, from inside Loop 410 out to the Loop 1604 suburbs, and our trucks are stocked for the day's most common calls, so most emergency repairs are one trip. We are licensed and insured under Texas RMP #36282. Not every drip is a same-day emergency, and we will say so: a slow faucet drip or a running toilet can wait for a scheduled slot, and we would rather book you a better price window than dispatch a truck you do not need today.
The 60-Second Shut-Off Decision Tree, by Emergency Type
Every emergency has one specific valve to close, and it is almost never the same one. Closing the wrong valve wastes the minutes that decide whether you get a point repair or a drywall claim. Match your situation to the list below, make the one move, then call 210-212-7667 and we will take it from there.
Leak under a sink, behind a toilet, or at a single fixture: turn the small oval or football-shaped stop valve on the wall directly below or behind that fixture, clockwise until it stops. That isolates the one fixture and leaves the rest of the house with water. If the stop valve is seized (common on pre-1970 fixtures in Alamo Heights and Monte Vista, where the original chrome stops corrode in place), skip to the main.
Leak you cannot see or trace, water heater flooding, or a burst line inside a wall: close the main house shutoff. On most post-1970 homes south of Loop 1604 it is where the supply line enters the house, often in the garage or an exterior wall near the hose bib. If you cannot find it, close the SAWS meter valve at the curb box using a meter key or a crescent wrench, a quarter turn until the tab is crossways to the pipe.
Water heater leaking from the tank itself: close the cold-water inlet valve on top of the heater (the one on the pipe feeding into it), then if it is gas, turn the gas control knob to OFF. Do not keep running a leaking tank, a failed tank can dump 40 to 50 gallons onto the floor.
Sewage backing up into a tub, floor drain, or the lowest fixtures: there is no valve to close here. Stop using every water source in the house instead, do not flush, do not run a tap, do not run the dishwasher or washer, because the main lateral is blocked and every gallon you send down comes back up. This is the one on the list to treat as a health emergency.
Gas smell near any appliance: do not touch a single valve or switch inside. People and pets out the door, leave it open, and from outside call CPS Energy at 1-800-870-1760 to shut the meter. We come in only after the utility secures the line.
Unsure which branch you are on? Call 210-212-7667 and describe what you see. We will walk you to the right valve on the phone before we ever roll a truck.
After-Hours Plumber San Antonio: How Our Hours Actually Work
Here is the honest answer most franchise pages will not give you. Our phones are staffed Monday through Friday, 8 AM to 5 PM, and that is when we dispatch same-day for calls placed by early afternoon inside Loop 1604. After-hours and weekend response may carry a surcharge, and we quote that amount before we roll a truck, never as a surprise line item on the invoice. We will not advertise a 24-hour dispatch fleet we do not run. What we will do, if you call after hours, is help you make the situation safe over the phone, which valve to shut, what not to touch, and book you the first slot that fits the urgency. A contained leak with the water shut off is no longer an emergency, it is a first-call-tomorrow job, and treating it that way usually saves you the overtime premium. Call 210-212-7667 and we will tell you which category you are actually in.
"24 Hour Plumber" vs Same-Day vs First-Call-Tomorrow: What You Actually Get
If you searched 24 hour plumber San Antonio, you were probably picturing a truck at your curb at 2 AM. Here is the part nobody spells out: for most emergencies, the truck showing up an hour later is not what protects your home, closing the right valve in the first sixty seconds is. Once the water is off, a real emergency becomes a controlled repair, and the smart move is almost always the tier that costs you the least, not the fastest one. Three tiers exist, and this is exactly what each one gets you.
Same-day, weekday (no premium). You call by early afternoon Monday through Friday, we dispatch a stocked truck the same business day inside Loop 1604, next-day first-call for Helotes, Schertz, and Converse. You get a firm ETA, an upfront written price, and one trip on most jobs. This is the tier the large majority of emergencies actually belong in, and it carries no overtime charge.
After-hours or weekend response (surcharge, quoted first). Genuine after-hours emergencies happen: a burst line at 9 PM you cannot get shut, sewage rising with the water already off and spreading, a gas situation the utility has cleared and you need the line repaired to restore heat. For those, response may carry a surcharge, and we quote that dollar figure before we roll, never as a surprise on the invoice. This is what a working, licensed local plumber can honestly offer instead of a fictional round-the-clock fleet.
First-call-tomorrow (the money-saver most people miss). A leak you have shut off and contained is no longer an emergency, it is a scheduled repair. Booking it as the first call the next morning skips the overtime premium entirely and gets you the same fix at the daytime price. We will tell you, honestly, when your situation belongs here instead of talking you into an after-hours roll you do not need.
So which are you? Here is the one-line test we use on the phone:
- Is water or sewage actively entering the home right now, with no valve you can reach to stop it? That is after-hours if it is after 5 PM, same-day if it is during the business day.
- Have you already shut the water off and contained it? That is first-call-tomorrow, and you will save money treating it that way.
- Is it a slow drip, a running toilet, or a heater that quit without leaking? Not an emergency at all, book a regular slot.
We will not sell you a midnight dispatch you do not need, and we will not pretend to run a 24-hour fleet to win the click. Call 210-212-7667, tell us what you see, and we will put you in the honest tier, which is usually the cheapest one that still solves it.
Sewage Backup Emergency: Why This One Cannot Wait
A sewage backup in San Antonio is the one call we treat as a genuine health emergency, not just an inconvenience. Raw sewage coming up through a floor drain, a tub, or the lowest fixtures in the house means the main lateral is blocked, and every flush and every running tap pushes more of it into your living space. If you rent, it is also a liability issue your landlord needs to act on immediately. Stop using all water in the house the moment you see it. We cable or hydro-jet the lateral at 4,000 psi to clear the blockage, then run a camera through the line and hand you a written report of what caused it, because in the pre-1970 housing stock around Monte Vista, Olmos Park, and parts of the West Side the cause is often a collapsed cast iron or Orangeburg lateral with pecan-root intrusion, not a simple clog. Knowing which one you have changes whether the fix is a clear-and-camera or a spot repair, and we will not sell you trenchless when a six-foot point repair will do. Call 210-212-7667 the moment sewage shows up.
Gas Smell Near a Water Heater or Appliance: Do This First, Then Call Us
If you smell rotten eggs or sulfur near the water heater, stove, or furnace, treat it as a gas leak until proven otherwise. Do not flip any light switches, do not unplug or plug anything in, and do not test it with a flame. Get everyone out of the house, leave a door open behind you, and from outside call CPS Energy at 1-800-870-1760 so they can shut the meter and secure the line. That is the order: people out, utility called, meter off. Only after the utility has cleared the line do we come in. We locate the exact leak point with an electronic detector, repair the fault, and pressure-test the whole line to 10 psi for 15 minutes minimum before anything gets relit. We do not guess, and we do not relight a system we have not proven tight. CSST flex line gets bonded per manufacturer spec, and permit-required gas work is filed through the City of San Antonio Development Services Department under RMP #36282.
When It Is NOT an Emergency (And You Can Save Money Waiting)
We would rather keep your trust than book a truck you do not need today, so here is when to skip the emergency call. A single faucet that drips, a toilet that runs but still flushes, a slow shower drain you can live with for a night, or one water heater that quit on a unit that is clearly past its service life and not leaking gas or water. None of those get worse fast, and dispatching reactively for them usually costs you more than booking a planned slot when we are not racing the clock. If the water is shut off and contained, you are no longer in an emergency, you are in a scheduled repair, and that is a better price every time. The honest test is simple: is water or sewage actively entering your home, is there a gas odor, or do you have no water at all? If none of those is true, call during business hours and let us book you the right slot rather than the fastest one. If you are not sure which side of the line you are on, call 210-212-7667 and describe it. We will tell you straight.
What Counts as a Same-Day Plumbing Emergency Here
Same-day slots fill fastest, so it helps to know where your problem lands. Definite emergencies we triage same day: an active leak you cannot stop, sewage backing into sinks or tubs, no water pressure to the whole house, a toilet overflowing that will not stop, and a gas odor near a plumbing appliance. These do not wait. Usually same-day if you call before noon: a single clogged drain, a running toilet wasting water, or a water heater that has stopped heating but is not leaking. These are bad but controllable. Most jobs are one trip because our trucks carry parts for drain stoppages, toilet repairs, common leak fixes, and water heater diagnostics for Rinnai, Navien, Rheem, and A.O. Smith units. When a job needs a special-order part or a City of San Antonio permit, we complete what we safely can the same day and confirm the return visit in writing. You approve an upfront price before any wrench turns, and if the scope changes inside the wall or under the post-tension slab, we stop, explain what changed, and get your go-ahead before continuing.
Frequently asked
What counts as a plumbing emergency?
A plumbing emergency is anything actively damaging your home or putting you at risk: an active leak you cannot stop, sewage backing up into sinks or tubs, no water to the whole house, a toilet overflowing that will not stop, or a gas smell near a water heater or appliance. For a gas odor, leave the building and call CPS Energy at 1-800-870-1760 first. For water problems, shut the nearest valve you can reach and call us at 210-212-7667. A slow drip or a running toilet is not an emergency and can wait for a scheduled slot.
There is no water in the house. Who do I call?
First check whether the outage is just you or the whole street. If neighbors also have no water, it is a SAWS main issue and you call San Antonio Water System, not a plumber. If only your house is dry, check that the main shutoff at the meter or where the line enters the house was not accidentally closed, and that a pressure-reducing valve has not failed. If the valves are open and you still have nothing, the problem is on your side of the meter and that is ours to fix. Call 210-212-7667 and we will trace it same day when you reach us during the business day.
Do you offer after-hours emergency plumbing in San Antonio?
Our phones are staffed Monday through Friday, 8 AM to 5 PM, which is when we dispatch same-day for most of the metro inside Loop 1604. After-hours and weekend calls may carry a surcharge that we quote before we roll a truck, never as a surprise on the invoice. If you reach us after hours, we will help you make the situation safe over the phone and book the first slot that fits. We will not advertise a 24-hour dispatch fleet we do not run.
Sewage is backing up into my tub. What do I do right now?
Stop using every water source in the house immediately, because every flush and every tap pushes more sewage into your living space through the blocked main lateral. Keep people and pets away from the affected area. Then call 210-212-7667. We cable or hydro-jet the lateral to clear the blockage, run a camera to find the cause, and hand you a written report. In pre-1970 San Antonio homes the cause is often a collapsed cast iron or Orangeburg lateral with root intrusion, which we will confirm with the camera before recommending a repair.
I smell gas near my water heater. What is the protocol?
Treat it as a gas leak. Do not flip light switches, do not plug or unplug anything, and do not test it with a flame. Get everyone out of the house, leave a door open, and from outside call CPS Energy at 1-800-870-1760 to shut the meter and secure the line. Only after the utility clears the line do we come in. We find the exact leak point with an electronic detector, repair it, and pressure-test the line to 10 psi for 15 minutes before relighting anything. Call us at 210-212-7667 after the utility has secured the meter.
How fast can an emergency plumber get to me?
Calls placed by early afternoon on weekdays are dispatched same day for most addresses inside Loop 1604, and we give you a specific ETA when you call rather than a wide window. Outlying areas like Helotes, Schertz, and Converse are typically first-call the following morning. Our trucks are stocked for the day's most common calls, so most emergency repairs are completed in one trip. Call 210-212-7667 and we will tell you honestly when we can be there before we confirm the dispatch.
Are you a licensed plumber for emergency work in Texas?
Yes. Armor Pro Services holds Texas RMP license #36282 and is licensed and insured. Permit-required emergency work, such as water heater changeouts and gas line repairs, is filed through the City of San Antonio Development Services Department under that license. We do not subcontract permit-required work to unlicensed crews, even on a same-day call.
Will you charge a surprise fee on an emergency call?
No. We give you an upfront written price that covers diagnosis and the proposed repair together before any work starts. If the scope changes once we are into the job, we stop, explain what changed, and get your approval before continuing. Any after-hours or weekend surcharge is quoted before we dispatch, not added later. You will not see undisclosed trip, dispatch, or diagnostic charges on the invoice.
Is there a 24 hour plumber in San Antonio, and are you one?
We will give you the straight answer: our phones are staffed Monday through Friday, 8 AM to 5 PM, and we do not run a round-the-clock dispatch fleet, so we will not advertise as a literal 24-hour plumber when we are not. What matters more than a truck at 2 AM is closing the right valve in the first minute, which turns most emergencies into a contained repair we can price calmly. After-hours and weekend response may carry a surcharge we quote before we roll. Call 210-212-7667 any time and we will help you make it safe over the phone and book the first slot that fits.
My leak is happening after 5 PM. Should I pay for after-hours or wait until morning?
It depends on one thing: can you shut the water off and contain it? If you close the fixture stop or the main and the water stops, the emergency is over and it becomes a first-call-tomorrow job at the regular daytime price, which saves you the after-hours surcharge. If water or sewage is still actively entering the home and you cannot stop it, that is a genuine after-hours call and we quote the surcharge before we dispatch. Call 210-212-7667 and describe it, and we will tell you honestly which side of that line you are on rather than pushing the more expensive option.
