Serving the Greater San Antonio Area
San Antonio, New Braunfels, Schertz, Converse — and every neighborhood in between. San Antonio's notoriously hard water leaves mineral buildup that chokes water heaters, fixtures, and supply lines — many emergency calls here start as a 'small' leak from a corroded fitting. The Hill Country limestone shifts with wet/dry cycles, stressing buried sewer lines, and sudden flash floods overwhelm drains and back up sewers in low-lying neighborhoods.
While you wait: shut the water off
- Find your main water shutoff valve — usually near the water meter or where the main line enters your home — and turn it clockwise.
- Turn off your water heater if it's leaking to prevent further damage.
- Keep people and pets away from standing water, especially near outlets and appliances.
- Move valuables and rugs away from the affected area if it's safe to do so.
Emergencies we handle in San Antonio
Every one of these is a call-now job. Each links to the San Antonio guide for that problem.
Burst pipe in San Antonio
A burst supply line can flood a room in minutes. San Antonio's hard water corrodes fittings over time, and Hill Country limestone shifts with wet and dry cycles, stressing buried lines — so a 'small' leak here is worth a fast call, not a wait-and-see.
Sewer backup in San Antonio
Wastewater coming up through a drain, tub, or toilet is a health hazard, not just a mess. Flash floods in low-lying neighborhoods can overwhelm drains and push sewers back into homes — keep people and pets away from the water and call right away.
Water-heater leak in San Antonio
Mineral buildup from San Antonio's hard water chokes water heaters until fittings fail. A heater that is leaking heavily, pooling water, or hissing needs the water — and the heater — shut off, then a pro.
Overflowing toilet in San Antonio
A toilet that keeps overflowing after plunging, or overflows with sewage, is an emergency call. Stop using that toilet, shut off its supply valve if you can reach it safely, and mop up only clean water.
Slab leak in San Antonio
A leak under a concrete slab shows up as damp flooring, a warm patch on the floor, or a water bill that climbs for no reason. Shifting limestone soil makes these more common here — they get worse quietly, so early detection matters more than speed of mopping.
Gas smell
If you smell gas near a water heater or appliance, leave the area first and call from outside — do not flip switches or try to find the leak yourself.
No water at all in San Antonio
No running water anywhere in the home is an emergency call. If pressure has dropped rather than vanished, the local low-water-pressure guide covers the common causes — but a total loss of water should not wait for troubleshooting.
Hard water and older homes: what the matched pro checks first
San Antonio's hard water is the thread running through many local emergencies: mineral scale builds up inside water heaters, narrows supply lines, and eats at fittings until one finally gives way. When a matched pro arrives for a leak or a failing heater, the first checks are usually the water heater itself — sediment and scale, the pressure-relief valve, and corroded connections — then the shutoff valves and the oldest visible fittings, because a second weak fitting often fails soon after the first.
Prevention follows the same logic: have the heater flushed and checked on a regular schedule, replace visibly corroded supply lines before they burst, and make sure you know where the main shutoff is before an emergency — flash-flood season is the wrong time to go looking for it. None of this replaces a pro's on-site diagnosis; it is simply what to expect them to look at first.
What to tell us when you call
Four answers get you matched faster and help the pro arrive prepared:
- What's happening — burst pipe, sewage, leak, no water, gas smell, or something else
- Where the water is — which room, and whether it is spreading
- Whether the main shutoff is off — if you have turned the water off, say so
- House or apartment — a house, an apartment, or a multi-unit building changes who else needs to know
