Plumbing Leak Detection in Houston is the process of locating hidden water leaks inside walls, under slabs, and beneath floors without tearing your home apart. We start by isolating your system with a pressure testing gauge, then confirm the loss with an electronic leak detector. From there we narrow the exact spot using a thermal imaging camera for temperature shifts and an acoustic listening device for the sound of escaping water. You get a marked location, a written finding, and a repair plan before we cut anything.
Houston homes sit on expansive clay soil that shifts with every wet and dry cycle, and that movement cracks copper pipe and stresses PVC joints. Add 13 years of freeze events, root intrusion from mature oaks, and pinhole leaks in older galvanized lines, and you get the leak calls we run every week. Whether you need plumbing leak repair Houston TX or a second opinion on a slab leak, we start with detection so the repair hits the right spot the first time.
Every detection visit covers the full diagnostic process, not just a quick look. Here is what you get when you book us, and what falls outside the standard scope.
We isolate your plumbing, irrigation, and sewer systems and pressure test each one with a hydrostatic test pump or gauge. This tells us which system is losing water and rules out the ones that are not.
We scan walls, floors, and ceilings with a FLIR thermal imaging camera and an acoustic listening device. On slab homes we grid the floor and log readings every 2 to 3 feet to narrow the location.
A moisture meter confirms what the thermal camera suggests. We map wet zones so you know how far the water has traveled and whether drying equipment is needed before repairs.
If the leak is on the drain or sewer side, we run a pipe inspection camera to find cracks, root intrusion, and offset joints. You see the footage and get a copy of the finding.
You get a written finding that names the leak location, the method used to confirm it, and photos of the readings. It is formatted for insurance claims and for any plumber you hire to do the repair.
If you want us to handle the fix, we quote it before we leave. If you want a second opinion, the report gives another contractor everything they need to pick up where we left off.
You call 832-839-4984 and describe what you are seeing: high bill, warm floor, wet baseboard, or a meter that never stops spinning. We ask a few questions to narrow the likely source and schedule a same-day or emergency visit across Houston. Most calls get a technician inside two to four hours.
On arrival we shut off fixtures and appliances, then pressurize the system with a hydrostatic test pump or pressure testing gauge. If the gauge drops, we know there is a leak. If it holds, we test the irrigation and sewer lines separately. This step takes 20 to 40 minutes and tells us exactly which system is losing water.
We walk the property with an electronic leak detector and an acoustic listening device, listening for the hiss of pressurized water escaping a pipe. On slab homes we grid the floor and log readings every 2 to 3 feet. This is where a slab leak or underground line leak usually reveals itself.
A FLIR thermal imaging camera shows temperature differences from hot water lines or evaporating moisture. For drains and sewer lines we run a pipe inspection camera to spot root intrusion, cracked PVC, or offset joints. We cross-check every hit against the pressure test so you are not paying to open the wrong wall.
We mark the leak location with tape or paint, hand you a written finding with photos, and walk you through repair options. If you want us to handle the fix, we quote it on the spot. If you are filing a claim, the report gives your adjuster the documentation they need.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Shows temperature differences from hot water lines and evaporating moisture on walls, floors, and ceilings. It is how we find leaks behind tile and drywall without opening them.
Picks up the sound of pressurized water escaping a pipe through concrete, tile, and drywall. On slab homes we grid the floor and log readings to narrow the leak to a few inches.
First-pass tool that senses moisture and pressure loss. It tells us which system to focus on before we bring in cameras or thermal gear.
Pressurizes a section of plumbing so we can watch for pressure drop. If the gauge falls, there is a leak. If it holds, we test the next system.
Runs inside drains and sewer lines to find cracks, root intrusion, and offset joints. You see the footage and get a copy of the finding.
Confirms what thermal imaging suggests and maps how far water has traveled. It tells us whether drying equipment is needed before repairs.
For hard-to-find leaks in underground lines or concealed spaces, we introduce a safe tracer gas and track it with a detector. It solves leaks other methods miss.
A Meyerland homeowner had a water bill that jumped from $90 to $340 in one month. The floor in the hallway was warm, and a foundation crack had appeared in the garage. Two other plumbers had guessed at the location and wanted to open three different sections of slab.
We pressure tested the system, confirmed a hot water slab leak, and used acoustic and thermal gear to narrow it to a 12-inch section under the hallway. The repair opened one small access point. The bill dropped back to normal the next cycle, and the foundation stopped moving.
A Heights homeowner noticed a musty smell in the living room and a faint stain on the ceiling. There was no visible water, and the AC drain had already been ruled out. The stain had been growing for about three weeks.
We used a moisture meter and thermal camera to map the wet zone, then confirmed a pinhole leak in a copper supply line inside the wall. The repair was a small drywall cut, one pipe section replaced, and the wall closed up. No mold remediation was needed.
A Bellaire homeowner had a soggy patch in the front yard and a water meter that never stopped spinning. The yard had a small sinkhole forming near the driveway, and the homeowner was worried about the foundation.
We traced the water main, pressure tested it, and used acoustic gear to hear the break about 18 inches below grade. The repair was a small dig in one spot. The sinkhole was filled, the meter stopped spinning, and the driveway stayed intact.
These are the calls we run most often in Houston. If any of them sound familiar, you likely have a hidden leak that needs detection before it gets worse.
Ask a pro →We isolate the system, pressure test it, and use acoustic and thermal tools to find the exact source. Most hidden leaks show up in under two hours of scanning, and you get a marked location and a written report before we leave.
A thermal imaging camera shows the temperature difference in seconds. We confirm with a pressure test, mark the spot, and give you a repair plan that opens one small section instead of the whole floor.
We trace the line, pressure test each zone, and use acoustic gear to hear the break underground. You get a marked dig spot so the repair is a small hole, not a trench across the yard.
We use a moisture meter and thermal camera to map the wet zone, then a pipe inspection camera if the drain is suspect. The leak gets located without tearing out the whole wall, and you get photos for your records.
$180 - $450 for most residential detection jobs, higher for slab, underground, or emergency calls
Most residential detection jobs in Houston run $180 to $450 in 2026, depending on the size of the property and how many systems we need to test. Slab and underground detection sits at the higher end because it takes longer and uses more equipment. Emergency after-hours calls add a dispatch fee. We quote the price before we start, and if you hire us for the repair, the detection fee is often credited toward the work. Affordable plumbing Leak Detection Houston TX means you know the number upfront and you get a written report either way.
Detection is the cheapest part of a leak repair. Guessing at the location means opening walls or breaking slab until you get lucky, and that costs ten times more than the scan. One visit, one report, and the repair hits the right spot.
A 1,200-square-foot bungalow takes less time to scan than a 4,000-square-foot home with multiple wings. Larger homes mean more pipe, more zones, and more time on the acoustic grid.
Supply, irrigation, sewer, and gas each get tested separately. A single-system leak is faster to find. If we have to rule out three or four systems, the job takes longer.
Slab homes need acoustic grid scanning and thermal imaging across the floor. Pier-and-beam homes let us access the crawlspace, which is faster. Slab detection sits at the higher end of the range.
A leak under a cabinet or behind an access panel is quick to reach. A leak under tile, behind a finished wall, or under a driveway takes more time and more careful scanning.
“Our water bill doubled and we could not find anything. Leak Detection The Heights came out the same day, pressure tested the system, and found a slab leak under the hallway with their acoustic gear. They marked it, wrote up a report, and our plumber opened one small section. Saved us thousands in guesswork.”
Marcus T.Homeowner, Meyerland
✓ Verified“We had a warm spot on the kitchen floor and no visible water. Their tech used a thermal camera and confirmed a hot water line leak in about an hour. He explained everything, showed us the images, and gave us a repair quote on the spot. No pressure, no upselling. We hired them for the fix too.”
Priya S.Homeowner, The Heights
✓ Verified“We manage a small office building and had a leak somewhere in the walls that three other companies missed. Leak Detection The Heights brought in a tracer gas detector and found it in a concealed chase on the second floor. The report was clean enough to hand straight to our insurer. Fast, professional, and they knew what they were doing.”

Start by shutting off every fixture and watching your water meter. If the dial still spins, you have a leak on the pressurized side. Check the water heater pan, toilet tanks, and under sinks for visible moisture. If nothing shows, the leak is likely in a wall or under the slab, and that is when you call us. We use a pressure testing gauge, thermal imaging camera, and acoustic listening device to pinpoint it without tearing up your floors.
You want a licensed plumbing contractor with leak detection equipment, not a handyman with a flashlight. Leak Detection The Heights handles both detection and repair, so you are not coordinating two companies. We work under Texas State Board of Plumbing Examiners licenses, carry insurance, and warranty our workmanship. If the leak is under a slab or inside a wall, we open the smallest access point possible and test the line before we close it up.
It depends on the cause. Sudden bursts, frozen pipe damage, and accidental discharge are usually covered. Long-term leaks from corroded pipes or poor maintenance are often excluded. Most Houston policies cover the water damage but not the pipe repair itself. Our written detection report includes photos and the leak location, which is exactly what adjusters ask for. We can also document the difference between a sudden failure and a slow leak.
Slab Leak DetectionSlab leaks are the most common hidden leak we find in Houston. We use acoustic listening and thermal imaging to locate the break under your foundation, then mark the spot so the repair hits one small section instead of the whole slab.Explore →
Foundation Leak DetectionWater under a Houston slab drives foundation movement, cracked brick, and sticking doors. We detect the leak source before it does more damage, then document the finding so your foundation contractor and insurer have what they need.Explore →
Pool Leak DetectionA pool losing an inch a day in Houston heat is not evaporation. We pressure test the plumbing, check the shell and fittings, and find the leak before it undermines the deck or wastes thousands of gallons.Explore →
Sewer Line Leak DetectionHouston's mature trees send roots into clay sewer lines. We run a pipe inspection camera to find cracks, root intrusion, and offset joints, then tell you whether the line needs a spot repair or a full replacement.Explore →
Gas Leak DetectionA gas smell is a call-now situation. We use a tracer gas detector and pressure testing to find leaks in gas lines, appliances, and fittings, then make the repair code-correct and safe.Explore →
Roof Leak DetectionHouston storms and summer heat punish roof flashing and penetrations. We trace roof leaks back to the entry point so you are not replacing shingles when the real problem is a failed pipe boot or vent seal.Explore →
Irrigation System Leak DetectionA broken irrigation zone can waste 500 gallons a day and go unnoticed until the bill arrives. We isolate each zone, pressure test the lines, and find the break without digging up the whole yard.Explore →
Water Heater Leak DetectionA water heater leaking from the tank, T&P valve, or fittings can flood a closet fast. We find the source, tell you whether it is a repair or replacement, and handle the fix the same day when parts allow.Explore →If your water bill jumped, your floor feels warm, or you hear water running with everything off, call us now.
