Tracer Gas Leak Detection in Chula Vista is the non-destructive way to find hidden leaks under slabs, behind walls, and inside irrigation lines. We pressurize the suspect line with a safe tracer gas blend, then sweep the surface with Sewerin and Gutermann detectors until the reading spikes. Homeowners in Otay Ranch, Eastlake, and Downtown Chula Vista call us when water bills jump or a gas odor lingers. We locate it, mark it, and hand you a repair plan the same day.
Tracer Gas Leak Detection in Chula Vista is a leak-location method that fills a suspect pipe or line with a non-toxic gas mixture, then tracks where that gas escapes to the surface. We isolate the line, cap the fixtures, and inject the blend at low pressure. A calibrated detector reads the gas concentration in the air just above the slab, soil, or wall cavity. Where the reading climbs, the leak sits. On a typical Chula Vista slab leak, we narrow a 40-foot run down to a 6-inch strike zone in under two hours.
Chula Vista homes built in the 1970s through the 1990s often sit on copper pipe that has thinned from hard water and soil movement. Pinhole leaks and slab leaks are common in Bonita Vista, Rancho del Rey, and Castle Park. When a water bill jumps $80 to $200 in one cycle, or you smell gas near the meter, tracer gas testing beats guesswork. We also use it on pool lines in Windingwalk and irrigation runs in Rolling Hills Ranch. If you have been searching for tracer gas leak detection service in Chula Vista CA near me, this is the call.
Every tracer gas test we run in Chula Vista includes the same core deliverables. You get the test, the marked location, and a written report. Repair work is quoted separately if you want us to handle it. Here is what is covered.
We shut off the main, drain the suspect branch, cap every fixture, and pressure-test with a gauge. This confirms the leak is on that branch before we introduce any gas. Takes 20 to 40 minutes on a typical Chula Vista home.
We introduce a 5% hydrogen and 95% nitrogen blend at under 5 PSI. The gas is non-flammable, non-toxic at test concentration, and vents from the line in minutes. No residue and no odor left behind in your home.
A calibrated Sewerin or Gutermann detector sweeps the slab, soil, or wall in 6-inch passes. When the reading spikes, we mark the spot with paint and take a depth reading. You see the marks before we leave.
You get a PDF report with the leak location, depth, pipe material, and photos of every mark. If you use your own plumber, the report gives them everything they need. If you want us to repair it, we quote it on the spot.
We vent the line and confirm the tracer gas has cleared before restoring service. A final pressure check confirms the line holds at operating pressure. You get the all-clear before we pack up.
If the leak is on copper pipe, PEX tubing, or PVC pipe, we can quote the repair the same day. Most slab repairs run $850 to $2,400 depending on access and pipe material. We pressure-test again after the repair and leave it holding.
You call (619) 943-1896 and describe the symptom: high water bill, damp slab, gas odor, or a pool losing an inch a day. We ask for your ZIP code and the approximate age of the home. Within 15 minutes you get a two-hour arrival window and a flat test price. No trip charges inside Chula Vista city limits.
On arrival, our technician shuts off the main, drains the suspect line, and caps every fixture on that branch. This takes 20 to 40 minutes on a typical Chula Vista home. We pressure-test with a gauge to confirm the line holds air before introducing gas. If it does not hold, we know the leak is on that branch and we proceed.
We introduce a 5% hydrogen and 95% nitrogen blend, the standard non-flammable tracer mix. Pressure stays under 5 PSI, well below what copper or PEX tubing sees in normal service. The gas is non-toxic at these concentrations and dissipates within minutes once we vent the line. No residue, no odor left behind.
Using a Sewerin or Gutermann detector, we sweep the slab, soil, or wall surface in 6-inch passes. Readings log in real time. When concentration spikes, we mark the spot with paint and take a depth reading. A typical slab leak sweep runs 60 to 90 minutes. We photograph every mark for your records.
Before we leave, you get a written report: leak location, depth, pipe material, and a recommended repair method. We note whether the line is copper pipe, PEX tubing, or PVC pipe. If you want us to handle the repair, we quote it on the spot. If you use your own plumber, the report gives them everything they need.

Our primary detector for hydrogen-nitrogen tracer gas. Reads down to parts-per-million concentrations, which lets us mark a leak within a few inches on a slab or soil surface.
Backup and cross-check detector. We run both on every job so a single detector fault never sends us to the wrong spot. Calibrated every 30 days.
Thermal imaging camera that shows temperature differences caused by escaping water. Excellent for finding the general area of a slab leak before tracer gas narrows it down.
Used on drain and sewer lines to find root intrusion, cracked PVC pipe, and blockages. Tracer gas handles pressurized lines; the camera handles gravity lines.
Confirm whether a line holds air before we introduce tracer gas. A line that loses pressure has a leak on that branch. A line that holds is intact or leaking elsewhere.
Pick up the hiss of pressurized water escaping a pipe. Fast first-pass tool on copper pipe under slab and exposed lines in walls. We confirm with tracer gas when the signal is ambiguous.
A family in Otay Ranch saw their water bill jump from $110 to $285 in one cycle. Two other companies wanted to cut open the slab in three places to look. No visible leak, no obvious wet spot.
After: We isolated the hot branch, pressure-tested it, and ran tracer gas. The detector spiked within 4 inches of the actual pinhole. The repair crew opened one 2-foot panel and fixed it in a day. Water bill returned to normal the next cycle.

A pool in Windingwalk was losing an inch and a half a day. Three dye tests found nothing. The pool company wanted to tear up the entire patio deck to find the leak.
After: We tested the return and suction lines with tracer gas and found a cracked return line 6 feet from the skimmer, under the concrete deck. The pool contractor opened one 3-foot section, replaced the fitting, and the pool held level.

A homeowner in Castle Park smelled gas near the meter. The utility confirmed a leak on the customer side of the meter but could not pinpoint it. The yard is landscaped with mature trees and a concrete walkway.
After: We confirmed the area with an electronic gas detector, then ran tracer gas along the buried service line. The detector spiked 12 feet from the meter, under the walkway edge. The repair crew dug one small hole, replaced the fitting, and the line held pressure.
Book this service →Most calls start with a symptom, not a diagnosis. Here are the four problems we hear most often, and how tracer gas testing turns each one into a fixed line.
Ask a pro →We isolate the hot and cold branches, pressure-test each one, and run tracer gas on the suspect side. Most Chula Vista slab leaks get marked within a 6-inch zone in under two hours. You get a repair quote the same day.
We use electronic gas detectors first to confirm the general area, then tracer gas to pinpoint the break. If the leak is on the utility side of the meter, we tell you to call SoCalGas. If it is on your side, we mark it and quote the repair.
We test pool return and suction lines with tracer gas without draining the pool. In Windingwalk and Eastlake, we have found leaks that three dye tests missed. You get a marked location and a repair plan for your pool contractor.
We test irrigation zones one at a time with tracer gas, which finds breaks at valve manifolds and elbow fittings 12 to 18 inches down. No trenching the whole yard. We mark the spot and your landscaper can repair it.
Most residential tracer gas tests in Chula Vista run $325 to $525 in 2026, depending on line type and access. A single slab leak test sits at the low end. Pool lines, irrigation runs, and multi-branch gas systems push toward the high end because they take longer to isolate and sweep. The price includes the test, the marked location, and a written report. No trip charge inside city limits.
The best service is the one that calibrates its detectors, isolates the line properly, and hands you a marked location with a repair plan. Ask any provider three questions: what gas blend do you use, how often are your detectors calibrated, and do you provide a written report. We use a 5% hydrogen blend, calibrate every 30 days, and include a photo report on every job.
Use it when you have a confirmed leak but no visible source. Common triggers: a water bill that jumped $80 or more in one cycle, a warm spot on the slab floor, a gas odor near the meter, or a pool losing more than an inch a day. Acoustic and thermal tools get you close, but tracer gas confirms the exact spot before anyone cuts concrete.
Yes. We use a 5% hydrogen and 95% nitrogen blend, which is non-flammable and non-toxic at test concentrations. Pressure stays under 5 PSI, far below normal operating pressure for copper pipe or PEX tubing. The gas vents from the line in minutes after testing and leaves no residue. We also verify the line holds air before introducing any gas.
If your water bill jumped or you smell gas near the meter, do not wait. We run tracer gas tests six days a week and hold emergency slots for gas calls. Flat pricing, calibrated detectors, and a marked location before we leave. Call (619) 943-1896 and we will confirm your arrival window.
