If water or sewage is actively damaging your home, it is an emergency. If you can stop it with a valve, it can usually wait for a scheduled visit.

Call now for burst pipes, sewage backing up into tubs or floor drains, any gas smell, no water to the whole house, or a toilet overflowing that will not stop. A slow drip from one fixture, a running toilet, or one slow drain can wait until morning once you close the angle stop under the fixture. Not sure? Call anyway. Our dispatcher will tell you honestly which one you have.

Average arrival is within 60 minutes inside Loop 410, and 45 to 90 minutes for outer areas like Stone Oak, Alamo Ranch, Helotes, and Schertz.

Our trucks stage around the city, which is what keeps those times real. Your dispatcher gives you a live ETA by text the moment a plumber is assigned to your call.

Yes, and any honest emergency plumber in San Antonio will tell you the same.

The difference is how it is handled. You see the full written price, before any work begins. There are no trip fees tacked on later and no surprise line items when the invoice prints.

Shut off your main water valve first. That single step prevents more damage than anything else we do later.

1. Find the main shut off. It is usually in the garage, a front yard valve box, or on an outside wall. Turn it clockwise until it stops.
2. Switch off the water heater at the breaker or gas valve so it does not fire dry.
3. Move electronics and furniture away from the water, and put down towels.
4. Clear the path to the water heater, cleanout, or problem fixture.

Leave the house immediately, do not touch any light switches or outlets, and call CPS Energy at 210-353-4357 from outside. That is their 24 hour emergency line, and they will shut the meter and secure the line.

Once the utility clears the site, call us. We pressure test the gas system, locate the leak, repair it to code, and coordinate the City of San Antonio inspection so your gas can be restored. Never test a gas smell with a flame, and do not re enter until the utility says it is safe.

Three local factors stack up: expansive clay soil, very hard water, and aging underground lines.

The clay soil under most of Bexar County swells when it rains and shrinks during drought, flexing the pipes under your slab until they crack. Edwards Aquifer water runs 15 to 20 grains per gallon of hardness, which scales and thins copper from the inside. And thousands of local homes are 40 plus years old with original pipe. Warm spots on the floor, a meter spinning with everything off, or a sudden jump in your SAWS bill are the classic early signs. Caught early, a reroute is usually far cheaper than the water damage.

Usually yes for sudden and accidental damage like a burst pipe. Usually no for slow leaks that went unaddressed.

Texas policies typically cover the resulting water damage, and many cover the cost of tearing out and replacing whatever it takes to reach the failed pipe. The pipe repair itself varies by policy. We photograph everything, document the cause in writing, and give you an itemized invoice formatted the way adjusters expect. The final call belongs to your insurer, but we make their job easy.

Yes. All work is performed under a Texas Responsible Master Plumber license, and the company carries general liability insurance.

Do not take any plumber's word for it, including ours. Verify any plumber's license for free on the Texas State Board of Plumbing Examiners license search. Our license number is printed on every truck and every invoice, because it should be easy to check.

Always. You approve a written flat rate quote before we pick up a wrench.

When there is more than one way to solve the problem, you get options with a price for each. A spot slab repair versus a full reroute is a common example. Nothing starts until you sign off on the number, and the number does not change afterward.

Sewage backing up into the house, an active leak you cannot contain, a gas odor, and a water heater dumping from the tank seam. Those four get a truck tonight, every time.

Water spreads under flooring and into drywall faster than most people expect, and turning a burst pipe into a mold problem costs far more than the after hours premium. Sewage is a health hazard on contact. If you are staring at a problem and unsure, call. Phone triage is free and we would rather talk you out of a call than have you wake up to a ruined floor.
