Leak Detection Services Available in Tomball
Tomball leak detection demand splits into two piles: slab and foundation leaks in the older core, and irrigation and pool leaks in the newer subdivisions. We cover both with the same truck stock. If you need affordable water Leak Detection in Tomball TX, start with a main-line pressure test; it tells us in 20 minutes whether the loss is inside the house or under the yard. From there we narrow it with acoustic and thermal tools before anyone picks up a shovel.
Slab Leak DetectionSlab leaks in Tomball usually show up as a hot spot on the floor or a water bill that jumps $80 in a month. We pressure test the system, then use a FLIR thermal imaging camera and acoustic listening device to mark the break on the slab. Most locations take 60 to 90 minutes, and we mark the cut zone so your plumber opens one square.View details →
Foundation Leak DetectionFoundation movement and plumbing leaks look alike in Tomball's clay soil. We separate them by testing the water system under pressure and checking for moisture with a General Tools moisture meter along the foundation line. If the leak is under the footing, we map it before anyone trenches. This saves homeowners in 77375 from paying for foundation work when the real problem is a pipe.View details →
Pool Leak DetectionPool leaks in Gleannloch Farms and Willow Creek often come from failed light niches or cracked skimmer throats. We use a dye test, a pressure testing gauge on the return lines, and a pipe inspection camera on the skimmer run. A pool losing a quarter inch a day in July is losing roughly 50 gallons, and we find where before the deck gets opened.View details →
Sewer Line Leak DetectionSewer line backups in older Tomball homes usually trace to root intrusion in clay tile or cast iron. We run a RIDGID pipe inspection camera from the cleanout and mark the depth and distance of the break. If the line is under a driveway or landscaping, we locate it before excavation so the repair stays small. Camera surveys run 45 to 75 minutes.View details →
Gas Leak DetectionGas leaks in Tomball get handled with a Sewerin tracer gas detector and a pressure test on the gas run. We check meter fittings, appliance connectors, and any buried yard line. If you smell gas, call us and step outside first. We locate the leak, isolate the section, and give you a written location so the repair crew knows exactly where to dig.View details →
Plumbing Leak DetectionPlumbing leaks behind walls in Tomball homes show up as bubbling paint or a musty smell in a closet. We use an electronic leak detector and thermal imaging camera to find the wet spot without opening drywall. Once located, we mark the stud bay and hand you a repair scope. Most concealed plumbing leaks take under an hour to locate.View details →
Roof Leak DetectionRoof leaks in Tomball often appear after a spring hail storm or a wind-driven rain from the northwest. We use a moisture meter and thermal imaging camera on the ceiling and attic decking to trace the water path back to the penetration. We do not repair roofs, but we tell you where the leak enters so your roofer fixes the right spot.View details →
Irrigation System Leak DetectionIrrigation systems in newer Tomball subdivisions run under lawns and flower beds, and a stuck valve can waste 200 gallons a day. We pressure test each zone with a gauge, then use an acoustic listening device to hear the break underground. Most zone leaks are located in 30 to 45 minutes without digging up the whole yard.View details →
Water Heater Leak DetectionA water heater leak in a Tomball garage or attic usually starts at the tank fitting or the T&P valve. We check the pan, the drain line, and the supply connections with a moisture meter. If the tank itself is seeping, we tell you straight: replace it. We locate the source so you are not replacing a heater when the real leak is a fitting above it.View details →
Pipe Leak DetectionPipe leaks in Tomball range from pinhole leaks in copper pipe to failed fittings in PEX tubing. We isolate the line with a pressure testing gauge, then listen with an acoustic device or trace with tracer gas. Once located, we mark the pipe and tell you whether a spot repair or a reroute makes more sense. Most pipe locations take under an hour.View details →
Electronic Leak DetectionElectronic leak detection uses a UEi or General Tools detector to pick up moisture and trace it to the source. In Tomball, this works well on concealed leaks under tile and behind cabinets where thermal imaging is blocked. We sweep the area, mark the highest moisture reading, and confirm with a second method before we call it located.View details →
Thermal Imaging Leak DetectionThermal imaging with a FLIR camera shows the temperature difference between wet and dry building materials. In Tomball slab homes, we use it to see the hot-water leak pattern on the floor before we pressure test. It is fast, non-invasive, and works through tile, carpet, and hardwood. Most scans take 20 to 30 minutes.View details →
Acoustic Leak DetectionAcoustic leak detection uses a listening device to hear the hiss or rush of water through a break. It works best on pressurized lines under Tomball slabs and in yards where the leak is 2 to 4 feet deep. We use it after the pressure test confirms a loss, and it usually pinpoints the break within a 12-inch circle.View details →
Tracer Gas Leak DetectionTracer gas detection pushes a safe gas mix into a line and sniffs for it at the surface. In Tomball, this is the tool for low-pressure gas lines, sewer laterals, and stubborn water leaks that acoustic tools cannot hear. We use a Sewerin detector and mark the surface location. It is the most accurate method for buried leaks under concrete or landscaping.View details →
Pressure Testing for LeaksPressure testing is the first step on every Tomball leak call. We isolate the system, charge it with a hydrostatic test pump, and watch the gauge for a drop. A 10 psi drop over 15 minutes tells us there is a leak and which side of the system it is on. This test takes 20 to 30 minutes and saves hours of guessing.View details →
Underground Leak DetectionUnderground leaks in Tomball yards often show up as a soggy patch or a water bill spike. We combine acoustic listening, tracer gas, and a pipe inspection camera to locate the break without trenching the whole yard. Once marked, the repair crew digs one hole. Most underground locations take 60 to 90 minutes.View details →
Concealed Leak DetectionConcealed leaks hide behind walls, under floors, and above ceilings. In Tomball homes, we find them with thermal imaging and electronic moisture detection, then confirm with a pressure test on the isolated line. We mark the exact spot so your drywall or cabinet repair stays small. Most concealed leaks are located in under an hour.View details →
Toilet Leak DetectionA running toilet in a Tomball home can waste 200 gallons a day. We check the flapper, fill valve, and wax seal with a dye test and moisture meter. If the leak is under the floor, we pressure test the drain line. Most toilet leaks are fixed with a $15 part, and we tell you when that is the case.View details →
Faucet Leak DetectionFaucet leaks in Tomball kitchens and bathrooms usually come from a failed cartridge or a loose supply connection. We check under the cabinet with a moisture meter and tighten or replace the fitting. If the leak has been running, we check the cabinet floor and the wall behind it for hidden damage. Most faucet leaks take 20 minutes to locate.View details →
Shower Leak DetectionShower leaks in Tomball homes often show up as a stain on the ceiling below or loose tile at the curb. We use a moisture meter and thermal imaging camera to find the source, then pressure test the shower valve and drain. If the pan is leaking, we tell you before you retile. Most shower leaks are located in 30 to 45 minutes.View details →
Bathtub Leak DetectionBathtub leaks in Tomball often come from the overflow gasket or the drain shoe. We fill the tub, dye test the overflow, and check the ceiling below with a moisture meter. If the leak is in the drain line, we run a camera. Most tub leaks are located in 30 minutes and repaired without opening the ceiling.View details →
Drain Leak DetectionDrain leaks in Tomball homes show up as a slow drip under a sink or a stain on a ceiling. We run water through the fixture and watch the drain line with a pipe inspection camera. If the leak is under the slab, we locate it with acoustic listening. Most drain leaks are found in under an hour.View details →
Sump Pump Leak DetectionSump pumps in Tomball are less common than in coastal areas, but crawlspace and elevator pit pumps still fail. We check the check valve, discharge line, and pit with a moisture meter. If the pump runs constantly, we pressure test the discharge to find the break. Most sump issues are located in 30 minutes.View details →
Water Main Leak DetectionWater main leaks in Tomball show up as a high bill or a wet spot between the meter and the house. We pressure test the main with a gauge, then listen with an acoustic device or trace with gas. The line is usually 3 to 4 feet deep, and we mark it before anyone digs. Most main leaks are located in 45 to 60 minutes.View details →
Fire Sprinkler Leak DetectionFire sprinkler leaks in Tomball commercial buildings often come from a failed head or a corroded pipe. We pressure test the zone with a gauge and use a moisture meter on the ceiling tiles. If the line is concealed, we use thermal imaging. We locate the leak and isolate the zone so the building stays protected.View details →
HVAC Leak DetectionHVAC leaks in Tomball usually mean a refrigerant leak or a condensate line clog. We use an electronic refrigerant detector and a moisture meter on the drain pan. If the condensate line is plugged, we clear it and check for water damage. Most HVAC leaks are located in 30 to 45 minutes.View details →
Refrigerant Leak DetectionRefrigerant leaks in Tomball AC systems show up as weak cooling and a compressor that runs nonstop. We use a UEi electronic detector and a pressure gauge on the suction line. If the leak is in the coil, we tell you before you recharge the system. Most refrigerant leaks are located in 30 to 60 minutes.View details →
Commercial Leak DetectionCommercial leaks in Tomball strip centers and offices cost money fast. We pressure test the domestic water and irrigation systems, then use acoustic and thermal tools to find the break without closing the business. We work after hours if needed. Most commercial leaks are located in 60 to 90 minutes.View details →
Residential Leak DetectionResidential leak detection in Tomball covers everything from a dripping faucet to a slab leak. We start with a pressure test, then use the right tool for the symptom: thermal imaging for slabs, acoustic for yards, moisture meters for walls. We mark the leak and give you a repair plan. Most homes are diagnosed in 60 to 90 minutes.View details →

How Leak Detection Is Executed in Tomball
Tomball sits on clay soil that expands and contracts with the seasons, and that movement is hard on slab foundations and buried pipe. We plan every job around it. On a typical call, we start with a pressure testing gauge
Clay soil movement cracking slab foundations
Tomball's clay soil swells after rain and shrinks in drought, and that cycle puts stress on the slab and the pipe running through it. A leak can open at a fitting or a bend where the pipe meets the slab. We see more slab leaks in late summer and early fall after a dry spell.
How we help: We pressure test the system first, then use thermal imaging and acoustic listening to find the break. We mark the cut zone on the floor so your plumber opens one square instead of several. We also check for foundation movement so you know whether the leak caused the crack or the crack caused the leak.
Irrigation systems leaking under lawns
Newer Tomball subdivisions like Willow Creek and Gleannloch Farms have irrigation systems with valves and lines buried 8 to 12 inches deep. A stuck valve or a cracked lateral can waste hundreds of gallons a week and show up only as a high water bill. The leak is often under grass, so it is invisible until the bill arrives.
How we help: We pressure test each zone with a gauge and listen with an acoustic device to find the break. We mark the head or line location with flags so your irrigation tech can dig one spot. If the leak is at a valve, we tell you before you replace the whole system.
Older copper pipe corroding from the inside
Homes near Old Town Tomball built before 1990 often have copper pipe that has thinned from years of slightly aggressive water. Pinhole leaks can show up behind drywall or under a cabinet. They start small and can spray a fine mist that damages cabinets and flooring before you notice.
How we help: We use an electronic leak detector and moisture meter to find the wet spot, then pressure test the line to confirm. We mark the stud bay and tell you whether a spot repair or a reroute makes more sense. If the pipe is failing in multiple spots, we tell you straight so you can plan the replacement.

“We had a slab leak in our home near Old Town Tomball and two other companies wanted to break up the whole floor. Leak Detection The Heights pressure tested the line, used a thermal camera, and marked one spot. The plumber opened one square and fixed it. They saved us thousands and the floor looks fine.”

“Our pool was losing water in Gleannloch Farms and we could not find where. They tested the returns and found a bad valve in about 30 minutes. They also checked the irrigation and found a cracked line. Straight answers, no upsell. I have already recommended them to two neighbors.”

“A pipe burst in our attic on a Sunday morning and water was coming through the ceiling. I called at 7 a.m. and a tech was at the house by 8:15. He found the break, shut it down, and gave us a repair plan. The price was fair and he did not try to sell us anything extra.”
