What our Underground Leak Detection includes
Every diagnostic visit covers the full locate-and-confirm process.

Work order
Underground Leak Detection- Full system pressure test: We isolate the domestic and irrigation lines and pressurize each one. A dropping gauge confirms an active leak and tells us which side of the system to focus on before we scan.
- Acoustic and thermal scan: Acoustic leak detection microphones and a thermal imaging camera run the length of the suspect line. We listen for the leak hiss and look for the temperature signature that shows where water is moving.
- Leak location marking: Once confirmed, we mark the spot with paint and flags, usually within 12 inches of the actual break. You get a photo of the mark and the pipe locator reading for your records.
- Written findings report: You get a one-page summary with the leak location, pipe material, access recommendation, and repair options. It is yours to keep, even if you get a second opinion.
- Repair quote on the spot: If you want us to fix it, we quote the repair before we leave. Most main line and irrigation repairs can be done the same visit. Slab repairs get scheduled within 48 hours.

Underground Leak Detection in Temecula, done right
A buried leak never gets smaller. It either gets fixed or it keeps moving water into your soil, your slab, and your water bill. Finding it properly the first time is what keeps the repair small.
Underground Leak Detection in Temecula is the process of locating water or gas escaping from buried pipes without tearing up your whole yard or floor. We pressurize the line, listen for the leak with acoustic sensors, scan the slab with a thermal imaging camera, and confirm the spot with a moisture meter and tracer gas where needed. Once we know exactly where the break is, we open a small access point instead of trenching blind.
Temecula sits on clay-heavy soil and sits through 100-degree summers that bake irrigation lines and shift slabs. Copper pipe from the 1980s and 1990s builds corrodes, PVC joints crack under root intrusion, and PEX fittings fail at crimp rings. If you need Underground Leak Detection near me Temecula CA, we run the full diagnostic the same day and tell you whether it is a slab leak, an irrigation leak, or a main line break.

How our leak detection process works
Every job follows the same five steps. You know what is happening, what it costs, and what comes next before we pick up a tool.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Shows temperature differences on the slab surface. A hot water leak reads as a warm streak, and a cold line leak reads as a cool one. We use it to narrow the search zone before we mark.
Pushes a safe gas mix into the suspect line and sniffs for it at the surface. This is our go-to when the leak is too small or too deep to hear with acoustic gear.
Runs a camera down the line to show cracks, root intrusion, and joint failures from the inside. We use it on drain and sewer lines where the leak is not under pressure.
Traces the exact path of a buried line so we know where to dig and where not to. It also confirms depth, which matters when you are working near a gas line or a pool line.

How Underground Leak Detection runs in Temecula
Temecula's climate and soil shape how we work. Summer ground temps push 100 degrees, which bakes irrigation lines and shrinks the expansive clay soil that most of our neighborhoods sit on.
Wolf Creek
Mostly 1990s builds with original copper supply lines. We see pinhole leaks at solder joints and slab leaks under the main hallway. Acoustic gear works well here because the slabs are conventional, not post-tension.
Harveston
Newer construction with PEX and PVC. Leaks here are usually at crimp rings and irrigation lateral lines. HOA rules restrict trenching in front yards, so we plan access points carefully before we dig.
Redhawk
Larger lots with long irrigation runs and mature trees. Root intrusion into PVC laterals is the most common call. We use a video pipe inspection camera to confirm the break before we cut.

PhotoSlab leak under a Wolf Creek hallway
Before: Two other companies had quoted a full slab break-out without locating the leak first. The tile was starting to lift at the grout lines.
After: We located the leak with thermal imaging and acoustic gear within 18 inches of the actual break. One 2-foot by 2-foot access cut, copper line repaired, and the slab patched.
Irrigation main break in Redhawk
Before: A 40-foot section of front lawn stayed soggy for two weeks. The homeowner shut off the irrigation and the wet spot stayed, which pointed to a main line leak feeding the soil from below. Water was pooling near the driveway.
After: We pressure tested the main, found a cracked PVC joint at a root intrusion point, and repaired it in about three hours.
Emergency main line leak in Old Town
Before: A restaurant owner called at 10 p.m. after hearing water running under the dining room floor. The meter was spinning fast and the water bill had doubled over the last quarter. They could not afford to close for a full day.
After: We dispatched a tech the same night, shut off the main, and ran the diagnostic. The leak was in a supply line under the kitchen. We repaired it overnight and had them open for lunch the next day. Water bill returned to normal the following cycle.
Underground leak problems we solve in Temecula
Most of our calls come from four problems.
Water meter spinning with everything off
That is an active leak somewhere on your side of the meter.
Soggy patch of lawn that will not dry
A wet spot that survives a week of 95-degree Temecula weather is not irrigation overspray.
Warm spot on the floor or a cracking tile
A warm patch on a slab usually means a hot water line is leaking underneath.
Unexplained jump in the water bill
A 20 percent jump with no change in use almost always means a hidden leak.
Why Temecula property owners call us first
A hidden leak can run for weeks before you see water.
Stop the water bill bleed

What Temecula customers say
Temecula Leak Pros came out the next morning, pressure tested the main, and found a slab leak under the hallway in about 90 minutes. They cut one small square, fixed the copper, and we have not had a problem since. Straight shooters.
I manage six rentals and I have used a lot of leak companies. These guys are the only ones who show up with a thermal camera and actually explain what they are seeing. They found an irrigation leak at one of my Paloma del Sol units that two other companies missed. Fast, clean, and they sent photos of everything.
Called at 9 p.m. on a Friday because we heard water running under the floor. They had a tech out by 10:30, shut off the right valve, and came back Saturday morning to do the full diagnostic and repair. I expected a nightmare and got a two-hour fix. Worth every dollar.

Four signs show up most often: your water meter spins with every fixture off, one patch of lawn stays soggy when the rest is dry, you hear running water at night, or your bill jumps 20 percent or more with no change in use. Any one of those is worth a diagnostic. Two or more means call us today.
The big three here are pipe corrosion on older copper, root intrusion into PVC joints, and soil movement from our expansive clay. Temecula also has hard water that scales the inside of copper pipe until it pinches through. Irrigation lines take a beating too, especially after a hot summer when the ground shrinks and pulls at fittings.
Yes, if the diagnostic confirms an active leak. Buried leaks do not seal themselves, and a slow one can move 200 gallons a day into your soil. We handle the repair the same visit on most main line and irrigation jobs. Slab repairs get scheduled within 48 hours so you are not living on a wet floor.
