Leak and slab detection in Houston 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.
Do not let anyone jackhammer your slab on a guess. A reputable detection ends with a marked location backed by readings, and the repair opening is small and targeted. If a contractor wants to open concrete without acoustic or thermal confirmation, get a second opinion first. Ours starts at (833) 834-1087.
How leak detection works
Slab leaks have a specific anatomy worth understanding. Water lines run beneath or within the concrete slab that forms the home’s floor and foundation. Where the pipe passes through the slab edge or changes direction, stress concentrates, and Houston Metro soil movement adds cyclic flexing that work-hardens copper until a pinhole opens. Hot lines fail first and most noticeably: the escaping hot water warms the slab above it, creating the classic warm floor spot, and it also accelerates the corrosion that opened the pinhole. Cold-line slab leaks are sneakier, showing only as a bill spike or damp flooring. Detection distinguishes them fast, because a warm signature on thermal imaging points straight at the hot line, cutting the search area dramatically.
Signs you need leak detection in Houston
- Warm spots on a concrete slab floor.
- The sound of running water when every fixture is off.
- Cracks appearing in floors, walls, or tile.
- White scale crusting on fixtures from hard water.
- Drains that back up every time a big storm rolls through.
What’s included
- Whole-property leak investigation: slab, walls, yard, and service line
- Meter-based confirmation testing on arrival
- Zone-by-zone pressure isolation to narrow the search
- Electronic and acoustic pinpointing of the exact spot
- Repair options quoted upfront: spot repair or reroute
Houston Metro: how local conditions affect leak detection
If there is a capital of the American slab leak, it is the Houston metro. Slab-on-grade construction puts water lines in or under concrete, and expansive clay puts that concrete in motion, swelling wet and shrinking dry through every season. The lines flex at their stress points until pinholes open, and because hot lines corrode faster, the classic symptom appears: a warm spot on the slab floor, a bill that jumped, the sound of running water with everything off. Houston homes with these signs should be tested this week, not next month.
Detection here is a race against foundation damage, not just water waste. Escaping water erodes the soil supporting the slab, and an unsupported slab cracks and settles, turning a plumbing repair into structural work. Our acoustic and thermal equipment pinpoints the leak before concrete is opened, because exploratory jackhammering on Houston clay is how small problems become big ones. The marked spot, the readings, and the photos become your repair plan and your insurance documentation.
Post-war and mid-century Houston homes add a second leak profile: aging galvanized and copper supply lines inside walls, where slow drips soak framing and feed mold long before they show. Moisture mapping and thermal imaging trace these to their source, and the repair is surgical. Whether the leak is under the slab or inside the wall, the discipline is the same: measure first, open once, and open only where the evidence points.
What affects the cost of leak detection in Houston
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 Houston Metro 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
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 Houston Metro soil really cause slab leaks?
Shifting clay flexes buried lines at stress points until pinholes open, so yes, soil movement is one of the leading causes here. Detection confirms the leak before anyone talks repair.
How do you find a leak under concrete?
Acoustic sensors, thermal imaging, and pressure tests triangulate the spot. We open concrete only where the leak actually is, and the opening is small and targeted.
Do slab leaks really happen that often here?
Expansive clay soil moves with moisture changes, and slab foundations feel it first. We pressure-test and use acoustic detection to confirm a leak before any concrete is opened.

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.
