What underground leak detection includes
Every detection visit covers the full diagnostic process from meter test to marked location. Repair is quoted separately so you can decide whether to use us or your own plumber. Here is what is included in a standard visit.
Acoustic and thermal scan
We walk the property with acoustic listening devices and a FLIR thermal imaging camera to narrow the leak to a specific area. You see the marked spot before we open anything.
Written findings and flat repair quote
You get a clear summary of what we found, where it is and what the repair will cost. No obligation to proceed. If you want a second opinion, take the findings to anyone you like.
Pipe material identification
We identify whether your line is copper, PEX, PVC or something older, because the repair method depends on it. That detail goes in the findings so there are no surprises on repair day.
Same-day repair option
If you want us to fix it while we are there, we carry the fittings, solder, Teflon tape and epoxy putty to handle most repairs on the spot. Same visit, one invoice, no second trip.
Underground Leak Detection in Brea, done right
Underground Leak Detection in Brea is the process of finding water or gas escaping from pipes buried under your slab, lawn or driveway without tearing up the whole property to do it. We start with a meter and pressure test, then use acoustic listening devices, ultrasonic leak detectors and thermal imaging cameras to narrow the break to within a foot or two. Once we know exactly where it is, we open the smallest possible area and make the repair.
Brea sits on a mix of older copper and newer PEX piping, and the clay-heavy soil around Orange County shifts with our dry summers and winter rains. That movement stresses pipe joints, and slab leaks, pinhole leaks and irrigation leaks follow. If you have been searching for underground leak detection near me Brea and getting nothing but guesswork, we do this every week in 92821, 92823 and 92822.

Tools and methods we use
Tools & Equipment
Acoustic listening devices
Pick up the sound pressurized water makes as it escapes a pipe. First tool we reach for on most underground leaks.
FLIR thermal imaging cameras
Show temperature differences on the surface above a leak. Warm water shows as a hot spot, cold water as a cool one.
Sewerin electronic leak detection equipment
Amplifies and filters leak sounds so we can hear through concrete, tile and packed soil.
RIDGID pipe inspection cameras
Push through a line to visually confirm cracks, root intrusion and joint failures from the inside.
Pressure testing gauges
Confirm whether the leak is on the supply side or the drain side and verify the repair holds before we leave.
Tracer gas detectors
Used on stubborn leaks and gas lines where acoustic and thermal gear cannot get a clear reading.
Moisture meters and infrared thermometers
Measure surface moisture and temperature to confirm the leak path and check for hidden moisture after repair.
Methods & Standards
Meter and pressure isolation
We shut off every fixture, watch the meter and pressure test the main. This confirms there is a leak and tells us whether it is on the supply or drain side before we bring out the acoustic gear.
Acoustic pinpointing
We walk the property with listening devices, moving in a grid until the sound peaks. That peak is the leak. We mark it with paint so you can see the spot before we open anything.
Thermal correlation
A FLIR camera shows the temperature signature of water under a slab or lawn. We cross-reference the thermal image with the acoustic reading to confirm the location to within a foot or two.
Tracer gas testing
For gas lines and stubborn water leaks, we introduce a safe tracer gas into the line and use a detector to find where it escapes. It is the most accurate method for deep or noisy locations.
Post-repair pressure verification
After every repair we pressure test the line again and re-check the meter. If it does not hold, we do not leave. That is how we know the fix is real.
When to call for underground leak detection
01
Your water bill doubled and the meter keeps spinning with everything shut off.
What we do: We run a meter and pressure test, then scan with acoustic and thermal gear to find the leak. Most jobs are pinpointed in two to four hours and repaired the same day.
→ You get a fixed line, a verified meter and a water bill that goes back to normal.
02
You see a wet spot on the slab or a warm patch on the floor in your Brea home.
What we do: We use a FLIR thermal imaging camera and acoustic listening devices to locate the line, then open the smallest possible section and repair it.
→ The leak is fixed with minimal concrete removal and the floor is patched clean.
03
Your yard has a soggy patch that never dries, even in summer.
What we do: We pressure test the irrigation zones and water main, trace the break with electronic leak detection equipment and repair the line.
→ The soil dries out, your landscaping recovers and you stop wasting water.
04
You smell gas near the meter or along a buried line.
What we do: We use tracer gas detectors and pressure testing to locate the leak, then repair the line to code. This is a call-now situation, not a wait-and-see.
→ The gas line is sealed, tested and safe, and the utility company signs off on the repair.
05
You are buying or selling a Brea home and the inspection flagged possible underground leaks.
What we do: We run a full detection scan and provide written findings you can hand to the buyer, seller or agent. Fast turnaround for escrow timelines.
→ You get a clear answer on whether there is a leak and what it costs to fix, so the deal can move forward.
How underground leak detection runs in Brea
Brea sits on clay-heavy soil that expands and contracts with our dry summers and winter rains, and that movement is hard on buried pipes. Older neighborhoods like Central Brea and Brea Hills have original copper that develops pinhole leaks. Newer builds in La Floresta and Lambert Ranch use PEX, which fails more often at fittings than in the pipe itself. We adjust our detection approach based on what we know is in the ground. In November, as the rains return, we see a spike in irrigation and water main leaks as saturated soil shifts. Summer brings slab leaks from heat-driven expansion. If you need 24/7 underground leak repair in Brea California, we run emergency calls year-round and can usually be on site within the hour.
Neighborhoods We Serve
-
Downtown Brea
Older commercial and residential buildings with original copper lines. Pinhole leaks and slab leaks are common in the older housing stock.
-
La Floresta
Newer construction with PEX piping. Most leaks we find here are at fittings and manifolds rather than in the pipe itself.
-
Country Hills
Hilly terrain with irrigation lines running down slopes. Pressure changes at the bottom of the hill cause lateral breaks.
-
Birch Hills
Established neighborhood with mature trees. Root intrusion into sewer and water lines is a recurring issue.
-
Olinda Village
Larger lots with long water main runs. Leaks here can go undetected for months because the line is so long.
Local Conditions We Plan For
-
Clay soil that expands and contracts
Soil movement stresses pipe joints and causes slab leaks and main line breaks, especially after the first winter rains.
-
Hot, dry summers
Heat drives irrigation demand and thermal expansion in buried lines, which is when pinhole leaks and irrigation breaks show up.
-
Mixed pipe materials across neighborhoods
Older copper and newer PEX fail differently, so we identify the material before we choose a detection method and repair approach.
-
Mature trees near sewer and water lines
Roots find cracks and joints and widen them over time. Camera inspection is often needed to confirm the extent of the damage.

Underground leak problems we solve in Brea
Most underground leaks start small and get expensive fast. Here are the problems we see most often in Brea and how we handle them.
Problem
Water bill jumped with no visible leak
A hidden pinhole or slab leak can waste 10,000 gallons a month and cost you hundreds before you notice anything wet.
Our Fix
We run a meter test and acoustic scan to find the source, then repair it. Most customers see their bill return to normal within one billing cycle.
Problem
Warm spot on the floor or a hissing sound
A warm spot usually means a hot water line is leaking under the slab. Left alone, it can undermine the foundation and crack tile.
Our Fix
We use thermal imaging and acoustic gear to pinpoint the line, open a small section and repair the copper or PEX. Most slab repairs finish the same day.
Problem
Soggy patch in the yard that will not dry
An irrigation or water main leak keeps the soil saturated, kills grass and can wash out soil under a driveway or walkway.
Our Fix
We pressure test each zone, trace the break with electronic gear and repair the line. We backfill and restore the surface before we leave.
Problem
Musty smell or new cracks in the foundation
Water under a slab softens soil and causes foundation movement. Cracks, sticking doors and musty odors are early warning signs.
Our Fix
We detect the leak, repair the source and confirm the soil is drying out. Catching it early avoids a five-figure foundation repair.
Why Brea homeowners call us first
A hidden leak can run for months before you see a wet spot. Here is what you get when you bring in a crew that finds the source before the shovel comes out.
-
Stop the water bill bleed
A pinhole leak in a copper line can waste 10,000 gallons a month. We find it, fix it and verify the meter stops spinning before we leave, so your next bill reflects the repair, not the leak.
-
Minimal digging, minimal damage
Because we pinpoint with acoustic and thermal tools first, we open a small access area instead of trenching the whole yard. That means less concrete to patch, less landscaping to replace and a faster return to normal.
-
Protect your foundation
Water under a slab softens soil and can crack foundations over time. Catching a slab leak early in a Brea home saves you from a repair bill that runs into five figures. We flag foundation movement while we are on site.
-
Same-day answers, honest pricing
Most detection jobs take two to four hours and you get a clear price before we start. No mystery invoices, no pressure to buy work you do not need. If the leak is simple, we tell you.

Real experiences from customers who chose our Underground Leak Detection services.
“Our water bill doubled in one month and we could not find anything. Brea Leak Detection Pros came out the same day, ran acoustic gear across the slab and found a pinhole leak under the hallway. They opened a small section, repaired the copper and pressure tested it. Bill went back to normal the next cycle.”

Frequently Asked Questions
Real answers to the questions we hear most often from local homeowners and property managers.
How much does underground leak detection cost in Brea CA?
Most underground leak detection in Brea runs $180 to $450 depending on how deep the line is and how many tools we need. A simple meter and acoustic test on an exposed main sits at the low end. Slab leaks that need thermal imaging and a pipe inspection camera land higher. You get the price before we start, and the repair is quoted separately.
How do you find an underground leak in Brea California?
We start with a meter and pressure test to confirm there is a leak, then use acoustic listening devices and a FLIR thermal imaging camera to narrow the location. On stubborn lines we add a tracer gas detector or push a RIDGID pipe inspection camera through the line. Most leaks are pinpointed to within a foot or two in two to four hours.
Who repairs underground leaks in Brea CA?
We do. Brea Leak Detection Pros holds a California State Plumbing License and a C-36 Plumbing Contractor License, and we handle both the detection and the repair. That means one crew, one price, one point of contact. We repair copper, PEX and PVC lines and pressure test every repair before we leave.
Can underground leaks be fixed without digging in Brea CA?
Sometimes yes. Small pinhole leaks in accessible copper or PEX lines can be repaired with a localized access point the size of a dinner plate instead of a full trench. Slab leaks usually need a small opening in the concrete. We always open the smallest area the repair allows, then patch and finish it clean.

Slab Leak Detection
Slab leaks are the most common underground leak we find in Brea. Warm spots on the floor, a spike in the water bill and the sound of running water with everything off all point to a line under the concrete. We pinpoint it with thermal imaging and repair it with minimal concrete removal.
View Slab Leak DetectionPool Leak Detection
A pool losing an inch of water a day is usually leaking at a fitting, light niche or underground return line. We use pressure testing and dye testing to separate evaporation from a real leak, then trace the line to the break before we dig.
