Not every hidden leak is under the slab. In Katy we also trace leaks inside walls, where a slow supply-line drip soaks insulation and framing; under yards, where the service line from the meter runs; and in pools and irrigation, which can masquerade as house leaks on the water bill. Our Leak & Slab Detection covers the whole property: we isolate zones with pressure tests to learn which part of the system is losing water, then narrow it with acoustic and thermal tools until the location is certain.
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 Katy detection visit.
How leak detection works
After the leak is found, the repair decision is engineering, not guesswork. A single pinhole in an otherwise sound line gets a targeted repair: open the slab or wall at the marked spot, replace the failed section with proper couplings, pressure-test, and restore. A line with multiple repairs already, or water chemistry that keeps eating copper, argues for rerouting: abandon the buried run and pull a new line overhead, which also removes every future slab leak on that branch permanently. In Katy, where Houston Metro water and soils keep attacking buried pipe, we quote both paths with honest trade-offs, because the smallest repair bill today is not always the smallest lifetime cost over the home’s life.
Signs you need leak detection in Katy
- A water meter that moves with everything in the house turned off.
- Mildew smells or mold growth on a ground-floor wall.
- Low water pressure that appeared gradually across the house.
- Warm spots or cracks appearing on a slab floor.
- White scale crusting on fixtures from hard water.
What’s included
- Acoustic leak listening with ground microphones
- Thermal imaging surveys of slabs and walls
- Pressure testing to isolate the leaking zone
- Slab leak pinpointing before any concrete is cut
- Sewer camera inspection where drain leaks are suspected
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. Katy 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 Katy 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 Katy
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
Should I repair or reroute a slab leak?
A first pinhole in a sound line: spot repair. Multiple prior repairs or aggressive water eating the pipe: reroute overhead and abandon the buried run. We quote both.
Will my insurance cover this?
Sudden water damage is typically treated differently from long-term seepage, which is why prompt detection and documentation matter. Our written report is formatted for filing.
How long does detection take?
Most Katy 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 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.

Other services in Katy.
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.
