What is included
What Our Slab Leak Repair Includes
Every slab leak repair we do in Fullerton includes detection, repair, pressure testing, concrete patch, and cleanup. We don't nickel-and-dime you for the basics. Here's what's covered.
Leak Detection
We use acoustic leak detection equipment, a thermal imaging camera, and a pressure testing gauge to pinpoint the leak. This is included in the flat-rate quote, not billed separately.
Pipe Repair or Reroute
We repair the damaged section with copper pipe or PEX tubing and new fittings. If a reroute makes more sense, we run new line through the attic or walls and abandon the old pipe.
Pressure Testing
After the repair, we pressurize the line and hold it to confirm there are no other leaks. We don't patch the concrete until the test passes.
Concrete Patch
We backfill the access hole and patch the concrete with a mix that matches your existing slab. The patch cures in 24 to 48 hours, and you can install flooring after that.
Cleanup and Haul-Away
We vacuum the work area, haul away debris, and leave your home ready for flooring. You won't find concrete dust on your furniture.

Service overview
Concrete Slab Leak Repair Fullerton CA
Concrete Slab Leak Repair Fullerton CA is the process of locating and fixing a broken pipe that runs beneath your home's concrete foundation. Most Fullerton homes built before 1990 have copper pipe under the slab, and after 30 or 40 years that copper corrodes, cracks at the joints, or pinholes through. When that happens, water seeps into the soil under your floor and eventually finds its way up through the slab. We use acoustic leak detection equipment and a thermal imaging camera to find the exact spot before we cut a single inch of concrete.
Fullerton sits on a mix of older clay soil and expansive ground that shifts with our dry summers and wet winters. That movement stresses under-slab pipes, especially at the joints. We see a lot of hot water line leaks in neighborhoods like Amerige Heights and Sunny Hills, where the original copper has been in the ground since the 1960s and 70s. If you're searching for concrete slab leak repair near me Fullerton CA, we can usually get a technician to your door the same day you call.
- Stop the Water Bill Spike — A pinhole leak in a hot water line can waste 10,000 gallons a month. That's real money down the drain. We find and fix the leak, and your next bill reflects it. Most customers see their water usage drop back to normal within one billing cycle after we complete the concrete slab leak fix Fullerton.
- Protect Your Foundation — Water under a slab softens the soil and causes the concrete to crack or settle. In Fullerton's expansive clay, that can mean foundation repair bills in the thousands. Fixing the pipe early prevents that. We also check for foundation moisture with a moisture meter before we leave.
- No More Mildew Smell — Standing water under your floor breeds mold and mildew. You might notice a musty smell in the hallway or see dark spots on the baseboards. Once we repair the under-slab pipe, the moisture dries out and the smell goes with it. We can also recommend a drying strategy if the saturation is heavy.
- Minimal Concrete Removal — We don't jackhammer your whole living room. With acoustic leak detection equipment and a pipe locator, we mark the exact spot and cut a small access hole, usually 18 to 24 inches square. After the repair, we patch the concrete and you can lay new flooring over it.
- Same-Day Service — We keep two trucks dedicated to slab leak calls in Fullerton. Call before noon and we can usually have a technician at your door the same afternoon. For emergency slab leak repair, we run 24/7 dispatch with a live person answering the phone.
- Upfront Pricing — You get a flat-rate quote before we cut anything. No hourly surprises, no overtime charges after 5 p.m. The price we quote includes detection, repair, concrete patch, and cleanup. If we find a second leak during the repair, we tell you before we touch it.
- Trenchless Options — When the pipe is too far gone to patch, we can reroute it using trenchless repair equipment. That means less concrete removal and a faster job. We'll explain whether a reroute or a spot repair makes more sense for your Fullerton CA concrete slab leak fix.
- Warrantied Work — Every slab leak repair we do comes with a workmanship warranty. If the same spot leaks again within the warranty period, we come back and make it right at no charge. We've been in business since 2016, so you know we'll still be here when you call.
The service timeline
How Our Slab Leak Repair Process Works
Phone Diagnosis
When you call, we ask a few questions: Is your water bill high? Do you hear running water when nothing is on? Is a section of floor warm? Those answers tell us whether it's a hot or cold line and roughly where to start looking. We schedule a same-day or next-day visit.
On-Site Leak Detection
Our technician arrives with acoustic leak detection equipment, a thermal imaging camera, and a pressure testing gauge. We pressurize the system, listen for the leak, and scan the floor for temperature changes. This takes 45 to 90 minutes and tells us exactly where the break is.
Repair or Reroute
If the leak is isolated, we cut a small access hole and repair the pipe with copper or PEX tubing and new fittings. If the line is too corroded, we reroute it through the attic or walls instead. We walk you through both options and the cost before we start.
Pressure Test and Patch
After the repair, we pressure test the line to make sure it holds. Then we backfill the hole and patch the concrete with a matching mix. The patch cures in 24 to 48 hours, and you can schedule flooring installation after that.
Cleanup and Walkthrough
We haul away debris, vacuum the work area, and walk you through what we did. You get a written summary of the repair, the warranty terms, and tips to watch for future leaks. Most jobs are done in one day.

Tools and Methods We Use
Acoustic Leak Detection Equipment
Listens for the sound of water escaping under pressure. We use it to narrow down the leak location before we cut any concrete.
Thermal Imaging Camera
Detects temperature changes on the floor surface. Hot water leaks show up as warm spots, which helps us pinpoint the line.
Pressure Testing Gauge
Pressurizes the plumbing system to confirm the leak and verify the repair holds after we finish.
Pipe Locator
Maps the path of under-slab pipes so we know exactly where to cut and where to avoid.
Video Pipe Inspection Camera
Lets us look inside the pipe to check for corrosion, scale, or joint failure that might cause another leak.
Electronic Leak Detection Wand
Picks up moisture and sound signatures through concrete. We use it as a secondary check after acoustic detection.
Acoustic Detection
We pressurize the line and listen for the leak with sensitive microphones. This works on both hot and cold water lines and is accurate to within a few inches.
Thermal Imaging
A thermal camera shows temperature differences on the floor. Hot water leaks appear as warm streaks. We use this to confirm acoustic findings.
Trenchless Repair
When possible, we repair or reroute the pipe without extensive concrete removal. This saves time, money, and mess. We use trenchless repair equipment for reroutes through the attic or walls.
IAPMO Uniform Plumbing Code Compliance
All repairs meet IAPMO Uniform Plumbing Code (UPC) standards. We use code-correct materials and methods so your repair passes inspection if needed.

Local execution
How Slab Leak Repair Works in Fullerton
Fullerton has a mix of older homes with copper plumbing and newer builds with PEX. The older neighborhoods like Amerige Heights and Sunny Hills see more slab leaks because that copper has been in the ground for 50 years or more. Our clay soil expands and contracts with the seasons, which stresses pipe joints. We also get calls from Coyote Hills Estates and College Green, where homes built in the 1980s are now hitting the age where under-slab pipe corrosion starts. If you need affordable concrete slab leak fix Fullerton California, we can help. We know the building codes, the soil, and the pipe materials used in this area. We also serve ZIP codes 92831, 92832, 92833, 92835, and 92836.
Amerige Heights
Many homes here were built in the 1990s and 2000s with copper under the slab. We see hot water line leaks as those pipes age.
Sunny Hills
Older tract homes with original copper plumbing. Slab leaks are common, especially on the hot water side.
Coyote Hills Estates
Larger homes with long plumbing runs under the slab. Leaks can be harder to locate, so we rely on thermal imaging.
College Green
Mid-century homes with original pipes. We often recommend reroutes here because the copper is near the end of its life.
Expansive clay soil
Fullerton's clay soil swells when wet and shrinks when dry. That movement stresses under-slab pipes and causes joint failures.
Hot inland summers
High temperatures speed up corrosion in hot water lines. We see more hot water slab leaks in July and August than any other month.
Older housing stock
Many Fullerton homes were built before 1980. Their copper pipes are reaching the end of their service life, making leaks more likely.
Before and after
What a successful service visit changes.
Water Bill Back to Normal
Before
A homeowner in Amerige Heights got a water bill for $340, triple the usual. They heard water running under the kitchen floor but couldn't see a leak. We detected a hot water line leak with thermal imaging.
After
We repaired the copper pipe, pressure tested the line, and patched the slab. The next water bill was $98, back to normal. The repair took five hours.
Maintenance: We recommended checking the water meter monthly for any unexpected spikes. Early detection keeps small leaks from becoming big repairs.
No More Mildew Smell
Before
A family in Sunny Hills noticed a musty smell in the hallway and dark spots on the baseboards. A home inspector found moisture under the slab but couldn't locate the source.
After
We used acoustic leak detection to find a cold water line leak under the hallway. Repaired it in four hours, dried the area, and the smell cleared within a week.
Maintenance: Keep an eye on baseboards for discoloration. If you smell mildew again, call us before it spreads.
Permanent Reroute Saves Floor
Before
A homeowner in Coyote Hills Estates had two slab leaks in three years. They didn't want to keep cutting into their tile floor. The copper line was corroded throughout.
After
We rerouted the entire line through the attic with PEX tubing. No concrete cutting, no floor damage. The job took two days, and the plumbing is now leak-free.
Maintenance: PEX tubing is resistant to corrosion and scale. It should last 50 years or more with no maintenance.
Problems we solve
Slab Leak Problems We Solve in Fullerton
Slab leaks show up in different ways. Some are obvious, like water pooling on the floor. Others are subtle, like a spike in your water bill or a warm spot on the tile. We solve them all.
Water bill suddenly doubled
A pinhole leak can waste thousands of gallons a month. If you ignore it, you're paying for water that's soaking into the ground under your house. We detect the leak with acoustic equipment and repair the pipe. Most customers see their bill return to normal within one billing cycle.
Warm spot on the floor
A hot water line leak heats the concrete above it. That warmth attracts mold and can warp hardwood or tile flooring over time. We use a thermal imaging camera to confirm the leak location, then repair the hot water line and patch the slab.
Sound of running water when nothing is on
That's the sound of water escaping under pressure. It won't stop on its own, and the damage gets worse every day. We pressure test the system to isolate the line, then use a pipe locator and video pipe inspection camera to find the break. Repair usually takes one day.
Musty smell or mildew in the house
Standing water under the slab breeds mold. The smell is a sign that moisture has been accumulating for a while. We fix the leak, dry out the area, and check for foundation moisture with a moisture meter. Once the source is gone, the smell clears.
