Leak and slab detection in Seguin is the process of finding hidden water leaks, under concrete slabs, inside walls, or underground, without tearing the house apart to look. The direct answer: if your water bill jumped, you hear running water with everything off, or a spot on your slab floor feels warm, you likely have a hidden leak, and acoustic and thermal detection can pinpoint it before any concrete is opened. Call (833) 834-1087.
Ask for the full report in writing: what was tested, what the readings showed, where the leak is marked, and what the repair options and prices are. You will need it for the repair decision, for insurance, and for your records if the home is ever sold. We provide it as standard on every Seguin detection visit.
How leak detection works
False positives waste more money than missed leaks, so ruling things out is half the job. A running toilet can waste as much water as a slab leak and shows on the meter identically, so fixtures get dye-tested first. Irrigation zones with stuck valves run silently at night and mimic service-line leaks on the bill, so the irrigation main gets isolated and tested separately. Water heater relief valves discharge to hidden terminations and get checked. Condensation on cold lines in Seguin’s humid seasons gets mistaken for active leaking and gets distinguished with moisture patterns. Only after the innocent explanations are eliminated does the acoustic gear come out, which is why our detection visits start with the boring checks.
Signs you need leak detection in Seguin
- The sound of running water when every fixture is off.
- Cracks appearing in floors, walls, or tile.
- Damp, warped, or discolored flooring with no visible source.
- A brown or rusty tint when you first run the tap.
- Recurring clogs in a home shaded by big old trees.

San Antonio Area: how local conditions affect leak detection
Clay and caliche soils keep San Antonio-area slabs in motion, and moving slabs open leaks. Seasonal wet-dry cycles flex foundations, stressing water lines at slab entries and direction changes until pinholes open. The signatures are the classics: warm floor spots over hot-line leaks, bills that jump, the sound of running water with everything off. Seguin homes showing these signs need detection this week, because escaping water erodes supporting soil and turns plumbing repairs into foundation work.
Century-old pipe adds the wall-leak dimension. Galvanized supply lines inside plaster and drywall corrode from the inside out, and slow drips soak framing for months before staining appears. Moisture mapping and thermal imaging trace these to their source without exploratory demolition, which matters enormously in historic Seguin homes where every opening is a restoration project. Measure first, open once.
Caliche complicates the repair side, which makes precise detection more valuable here, not less. Digging through caliche is slow and expensive, so a marked location backed by acoustic and thermal readings saves real money on every buried repair. Our detection reports give the repair crew, and your insurance adjuster, exact locations with readings and photos, turning a dreaded project into a planned one.
What affects the cost of leak detection in Seguin
Repair method is the big cost fork. Spot repair through the slab is usually less upfront: one opening, one fixed section, one restoration. Rerouting the line overhead costs more in pipe and patching but abandons the buried section entirely, ending that branch’s slab-leak risk forever. For a first pinhole in a young line, spot repair wins. For a line with prior repairs, or San Antonio Area water that keeps eating copper, rerouting is often the better lifetime math. We quote both and explain the trade-off in plain terms.
- Spot repair versus full reroute pricing
- Age and condition of the rest of the line
- Water chemistry and its effect on future failures
- Restoration costs: flooring, tile, drywall
Common questions
How long does detection take?
Most Seguin homes are diagnosed in a single visit. Pressure isolation narrows the zone quickly, and acoustic pinpointing usually follows within the same appointment.
Can a slab leak cause foundation problems?
Yes. Escaping water washes out the soil supporting the slab, and an unsupported slab cracks and settles. This is the real reason slab leaks cannot wait.
Do you have to tear up my floors?
Only at the marked spot, and only as much as the repair needs. Detection exists precisely to avoid exploratory demolition.
What if you find no leak?
Then we tell you so, honestly, and point at the next most likely cause: running fixtures, irrigation, or the service line. You pay for the investigation, not a repair you did not need.
Does hard water really matter?
It cuts water heater life and clogs fixtures. A softener is one of the highest-return improvements for a home here.

Emergency Plumbing
Emergency plumbing is immediate response to water damage in progress — burst pipes, major leaks, sewage backups, and total water loss. You reach a live dispatcher who triages the situation on the call and routes a stocked truck immediately, so the water stops as fast as possible.
Water Heater Installation & Repair
A water heater supplies hot water to every faucet, shower, and appliance in your home — tank models store it, tankless models heat it on demand. We repair failed burners, thermostats, and heating elements, and size replacements to your household’s actual hot-water demand so the showers stay hot.
Drain Cleaning
Drain cleaning removes the blockages that slow or stop wastewater flow — grease, soap, hair, scale, and root intrusion. We match the tool to the clog: drain snakes for branch lines, inspection cameras for diagnosis, and hydro jetting to scour the pipe wall on main-line stoppages.
Sewer Line Services
A sewer line carries all wastewater from your home to the city main, so a failure here backs up every drain at once. We inspect with an HD camera first, then clear root intrusion or repair damaged sections — replacing the line only when the pipe itself is truly done.
Whole-Home Repiping
Repiping replaces every water supply line in the home at once, ending the cycle of one leak after another. We install new PEX or copper pipe through minimal wall openings, pressure-test the system, and leave it up to current code.
Gas Line Services
Gas lines feed stoves, water heaters, dryers, and grills — and any work on them has to be exact. We repair damaged sections, extend lines for new appliances, and set new appliance hookups, pressure-testing every joint before the job is signed off.
Water Treatment & Filtration
Water treatment conditions your supply water so mineral hardness and contaminants stop damaging fixtures, appliances, and the water heater. We test your water first, then install whole-home softeners and filtration matched to what the test shows.
