A mystery water bill in Garland usually ends at one of two places: a running fixture or a buried leak. We rule out the easy stuff first, toilets, irrigation, the water heater relief valve, then bring out the listening equipment and cameras until the leak has nowhere left to hide. Every Leak & Slab Detection visit ends with evidence: readings, photos, and a marked location, not a shrug and a guess.
While waiting for detection, minimize water use but do not shut off the main for days: a house without water pressure cannot be properly tested, and dry traps invite sewer gas. Keep usage light, note any changes in the symptoms, and keep the area around the suspected leak clear for equipment access.
How leak detection works
Leak detection is applied physics, and the order of operations matters. We start with pressure: the system is divided into zones, supply branches, irrigation, the service line, and each is pressurized and watched. A zone that will not hold pressure is the leaking zone, and that single test eliminates most of the house from suspicion. Next comes sound: pressurized water escaping through a pinhole creates a distinct high-frequency hiss, and acoustic sensors with ground microphones amplify it while filtering ambient noise. The tech sweeps the slab or yard in a grid, and the sound peaks directly over the leak. Thermal imaging adds a second witness: escaping water changes the temperature of the surrounding slab or soil, and an infrared camera renders that difference as a visible pattern. Used together, pressure isolates, acoustics pinpoint, thermal confirms, and the repair opening lands on the leak, not near it. In Garland, where Dallas-Fort Worth Metroplex soils complicate everything buried, this methodical sequence is what keeps a detection visit from becoming an excavation project.
Signs you need leak detection in Garland
- Damp, warped, or discolored flooring with no visible source.
- A water meter that moves with everything in the house turned off.
- Mildew smells or mold growth on a ground-floor wall.
- Pipes in the garage or attic that have frozen before.
- Cracks widening in walls or floors near plumbing runs.
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
Dallas-Fort Worth Metroplex: how local conditions affect leak detection
Black gumbo clay makes the Metroplex prime slab-leak country. Few soils in Texas move more dramatically between wet and dry, and slab foundations transmit every inch of that movement to the water lines cast within or buried beneath them. Pinholes open at stress points, hot lines first, and the signatures follow: warm floor spots, doubling water bills, the hiss of running water with everything off. Garland homeowners who notice any of these should treat detection as this-week business.
The drought-then-deluge cycle is the trigger mechanism. Long dry spells shrink the clay and open gaps around the slab; sudden storms swell it back, shifting the foundation and shearing lines that survived the dry months intact. Leaks that begin in these transitions run silently, eroding supporting soil with every gallon. Our detection sequence, pressure isolation, acoustic pinpointing, thermal confirmation, finds the leak before the soil loss becomes a foundation problem, and the written report documents everything for insurance.
Fast-growth construction adds leak paths unique to the Metroplex. Rushed joints in boom-era builds, copper lines in contact with concrete without proper sleeving, and slab penetrations sealed poorly all become leak points as the clay works them. During detection we map the home’s era against its symptoms, because a 1990s tract home and a new build leak for different reasons. Either way, the discipline holds: measure first, open once, open only where the evidence points.
What affects the cost of leak detection in Garland
What the leak has already damaged affects the total. A leak caught from a bill spike may need only the pipe repair. One that has been running for months can mean mold remediation, damaged flooring, or compromised sub-slab soil, which are separate trades with separate costs. Our detection report documents visible damage honestly so you can plan, and we coordinate with the repair crew to keep the plumbing scope tight and clear. In Garland, early detection is genuinely the difference between a plumbing bill and a construction project.
- Extent of secondary damage: mold, flooring, finishes
- How long the leak has been active
- Whether soil under the slab needs attention
- Plumbing scope kept separate from restoration scope
Common questions
What does leak detection cost?
The detection visit is flat-rate and includes the full investigation plus a written report. The repair is quoted separately once we know what and where the problem is.
Can you detect leaks in walls too?
Yes. Moisture mapping and thermal imaging trace wall and ceiling leaks to their source, and we open surgically once, in the right place.
My water bill doubled but I see no leak. Now what?
Do the meter test: everything off, watch the leak indicator. If it moves, call (833) 834-1087. Hidden leaks show on the bill weeks before they show anywhere else.
What is the warm spot on my floor?
Almost always a hot-water slab leak: escaping hot water warms the concrete above it. Thermal imaging confirms it in minutes.
How do I protect pipes from a Texas freeze?
Insulate exposed lines, know your main shutoff, and let faucets drip in a hard freeze. If a pipe bursts, shut the water off and call us, we answer around the clock.

Other services in Garland.
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.
