Slab Leak Detection in Murrieta, CA
Warm floor spots, a doubled water bill, or the sound of water at night can all point to a slab leak. We find the exact spot before anyone picks up a jackhammer.
What is a slab leak?
A slab leak is a break or pinhole in a water line that runs under or inside your home's concrete foundation. Because the pipe is buried, the water can run for weeks unseen. Slab leak detection finds the exact spot so repairs stay small and targeted.
Most Murrieta homes are built on concrete slabs, and many of the water lines run through or beneath them. Over time, shifting ground, hard water, and the slow wear of copper pipe can cause a pinhole leak. The water then soaks the soil under your floor.
A slab leak will not fix itself. It can lift flooring, crack tile, feed mold, and push your water bill up month after month. The sooner it is found, the smaller the repair tends to be.
What are the signs you may need slab leak detection?
Watch for these common warning signs:
- Water bill that jumps with no change in habits
- Sound of running water when every fixture is off
- Warm or hot spots on the floor
- Cracks in walls, tile, or the foundation
- Damp carpet or a musty smell near the floor
- Water meter that keeps moving when the house is off
- Low water pressure at several fixtures
- Water heater that runs more than normal
How does our slab leak detection process work?
- 1
Isolate the line
We shut off fixtures and pressure test the lines to learn which pipe is losing water.
- 2
Listen through the slab
Acoustic listening and electronic amplifiers pick up the sound of water escaping.
- 3
Scan for heat
Infrared thermal imaging shows warm patches where a hot line is leaking.
- 4
Mark and explain
We mark the spot on your floor, show you the evidence, and talk through repair options.
What equipment do we use?
- Electronic leak amplifiers
- Ground microphones and acoustic listening devices
- Infrared thermal imaging camera
- Hydrostatic pressure testing equipment
What is different about Murrieta?
Murrieta and nearby Temecula Valley neighborhoods sit on slab-on-grade foundations, and the area’s clay-rich soils can shift as they dry and swell. Hard water in the Inland Empire also wears on copper lines over the years. Those two things are common reasons we are called out for under-slab leaks in Murrieta, Temecula, and Menifee.
Infrared and thermal leak detection in Murrieta
Infrared leak detection uses a thermal imaging camera to read small temperature changes on floors and walls. A leaking hot water line warms the slab above it, and a cold line can leave a cool, damp patch. The camera shows those patterns without cutting into anything.
Thermal imaging works best on hot water lines and on leaks close to the surface. It is one tool, not the whole test. Your technician pairs it with pressure testing and acoustic listening to confirm the exact spot before any repair is planned.
- Good for: warm floor spots, hot water slab leaks, damp areas inside walls and ceilings
- Less useful for: deep cold water lines, thick tile over the slab, leaks outside the house
- Non-invasive: no drilling or cutting is needed to take the images
Hidden leaks in walls and ceilings are covered by our water leak detection service, and if your pool keeps dropping, see pool and spa leak detection. Once a slab leak is found, slab leak repair and trenchless options are priced before any work starts.

Frequently asked questions about slab leak detection
How do you find a slab leak without cutting concrete?
We combine acoustic listening devices, electronic amplification, and thermal imaging to narrow the leak to a small area. That means any access point we open is small and in the right place.
What affects the price of slab leak detection?
Cost depends on the type of leak, the size of your property, and how hard the leak is to reach. We explain the price up front, before a technician is sent. See the cost section on this page for typical ranges, or call us for a clear answer for your home.
Is a slab leak an emergency?
Treat it as urgent. If you can, shut off the main water valve to stop the damage, then call us. Water under a foundation can cause costly damage the longer it runs.
Can a slab leak damage my foundation?
It can. Water that keeps soaking the soil under a slab may soften it and add to cracking or shifting over time. Finding the leak early lowers that risk.
Do you use infrared cameras to find slab leaks?
Yes. Infrared thermal imaging is one of the tools used on slab leak calls in Murrieta. It is most useful for hot water lines, and it is always confirmed with pressure testing and acoustic listening before a spot is marked.
How much does slab leak detection cost in Murrieta?
Slab leak detection in Murrieta usually costs about $250 to $650, depending on the size of the home and how many lines need testing. Repairs start from about $300 and are quoted after the leak is found. See slab leak repair in Murrieta.
