Slab Leak Repair
Clay that swells and shrinks with the seasons works on every supply line cast under a slab.
Slab Leak RepairSan Antonio 24 Hour Plumber answers 24-hour calls in Converse, the northeast Bexar County city beside Randolph Air Force Base. Its subdivisions run from the 1970s to houses finished in the last few years, all of them on slab over heavy clay.

Clay that swells and shrinks with the seasons works on every supply line cast under a slab.
Slab Leak Repair
A wet strip of lawn or pressure that fell everywhere at once points at the line from the meter.
Water Line Repair
Ground movement pulls drain joints apart, and roots find the opening within a season or two.
Sewer Line RepairConverse grew outward in waves, and the wave your street belongs to tells a plumber a great deal before they arrive. The older sections built through the 1970s and 1980s are single-story slab houses with copper supply lines and cast-iron or early plastic drains that have now spent decades in moving ground. The newest subdivisions on the edges of the city were finished with plastic supply piping and modern drains, which fail far less often but are laid in exactly the same clay.
That clay is the common factor. It swells after a wet spell and shrinks hard through a dry summer, and everything buried in it gets pulled slightly out of line each time. In older houses the result tends to be a slab leak or a drain joint that has opened. In newer ones it is more often a sewer line that has lost its fall, or a water line out in the yard that has been stressed at a fitting. Age changes the symptom, not the cause.
Tell us roughly when the house was built and whether any plumbing has been replaced. It narrows the likely fault before anyone opens a wall.
The main shutoff for most homes here is a valve inside the meter box at the curb. Clear the lid of grass now, not while water is running.
Rear cleanouts behind locked gates cost time on a night call. Give the code or leave the gate open when you know we are on the way.
The useful question in Converse is whether a problem is a one-off or a pattern. A single blocked drain after a heavy cooking weekend is exactly what it looks like. The same line blocking twice in a year is not, and that is when a camera earns its money — it shows whether the pipe has dropped, cracked or simply collected grease. The answer decides between clearing it again and repairing a section.
The same logic applies under the slab. One leak in a house that has never had trouble is usually worth a spot repair. A second leak in the same run is the line telling you its age, and rerouting it overhead often ends the cycle. Whatever is recommended, ask what the test or the camera actually showed and what the repair is expected to buy you.
If a water heater is part of the picture, the water heater repair versus replacement guide sets out both sides. We also cover emergency plumbing in Universal City next door, along with every community on the service areas page.
The price is quoted at the property once the cause is known, and it is driven by the repair rather than the hour of the night. Clearing a drain, replacing a failed section of pipe and excavating a yard line are very different scopes. San Antonio 24 Hour Plumber does not quote a figure over the phone for work nobody has seen yet — our service process page explains how the quote is put together.
San Antonio 24 Hour Plumber locates and repairs slab leaks across Converse at any hour. The line is pinpointed first, then you choose between opening the slab at that spot, rerouting the run overhead or repiping. Read slab leak repair for what each route involves, and turn the water heater off if the warm patch suggests the hot side.
Yes, in most cases. Give the address and San Antonio 24 Hour Plumber will confirm a realistic window, with active leaks and sewage backups taking priority over scheduled work. If a part has to be sourced for an older fixture, you will be told before approving anything. Tell us what is happening and we will plan the visit.
Not if water is spreading across floors or near outlets and appliances. Shut the main off at the meter box, keep people away from wet flooring around electrical points, and do not try to open a pressurized line yourself. A slow leak with nothing pooling can wait a few hours, but it should not wait weeks. San Antonio 24 Hour Plumber covers the first steps on the burst pipe guide.
Most often the buried supply line between the meter and the house, or an irrigation fault. The quick check is to turn everything off indoors and watch the meter dial: if it still moves, water is escaping before it reaches the house. San Antonio 24 Hour Plumber isolates the line to prove which side the loss is on before any digging starts — see water line repair.
Less often, but yes. Newer subdivisions here were built with plastic supply lines that tolerate movement far better than copper, so the failures tend to be at fittings rather than along a run. The soil under them is the same clay the older streets sit on, which is why sewer lines losing their fall show up in newer houses too. A leak detection visit settles it either way.
