Many homes across San Jacinto, Hemet, and the surrounding Inland Empire were built between the 1960s and 1990s, often with copper supply lines running directly beneath the concrete slab. Decades of shifting soil, ground movement, and ordinary water-pressure cycling put steady stress on those aging lines, and copper pipe from that era is now well past the point where a pinhole leak under the slab is a realistic, common failure — not a rare event.
Once we've confirmed and precisely located a slab leak using acoustic and thermal detection equipment, the right fix depends on the specifics of your situation. A single, isolated leak in an accessible spot may only need a targeted spot repair. A leak in a hard-to-reach location, or a pipe run showing early signs of failing elsewhere too, is often better solved by re-routing that line through the attic or walls rather than repeatedly opening the slab. If your home's copper or galvanized lines are broadly reaching the end of their service life, whole-home repiping can end up being both the more honest and more cost-effective path — and we'll tell you plainly if we think that's the case, rather than defaulting to the smallest possible repair every time.
Every slab leak repair starts with a written estimate for the specific option you choose, and we only open the minimum amount of flooring necessary to complete the work. No exploratory demolition, and no guessing.

How Slab Leak Repair Works
We pressure-test the plumbing system to confirm a leak is present under the slab before any further diagnosis begins.
Acoustic listening equipment and thermal imaging pinpoint the leak's location under the foundation to within inches — no exploratory jackhammering.
Depending on the pipe's age, material, and the leak's location, we walk you through the realistic options: a spot repair, a re-route above the slab, or — for older homes with multiple aging lines — whole-home repiping.
We complete the agreed-upon repair with minimal concrete or flooring removal, then pressure-test the system again to confirm the fix holds.
We patch the access point and do a final walkthrough so you know exactly what was done and what to watch for going forward.

Common Questions About Slab Leak Repair
How do I know if I have a slab leak?
The most common signs are a warm spot on your floor, the sound of running water when everything is off, an unexplained jump in your water bill, or low pressure throughout the house. If you notice any of these, call us for a free assessment.
Will you have to jackhammer my entire floor to find the leak?
No. We use non-invasive acoustic and thermal detection equipment to locate the leak within inches first. We only open the minimum amount of concrete or flooring necessary to make the repair.
Why are slab leaks so common in San Jacinto and Hemet?
Many homes in this area were built between the 1960s and 1990s with copper supply lines running under the slab. Decades of soil movement and pressure cycling put real stress on pipe from that era, which is why slab leaks show up so often in this housing stock specifically.
Should I repair the leak or repipe the whole house?
It depends on the pipe's age and condition and whether this is an isolated issue or a sign of broader failure. We'll walk you through both options honestly — including telling you if a repair now likely just delays a repipe you'll need soon anyway.
How much does slab leak repair cost?
It depends on the repair method — spot repair, re-routing, or repiping — and where the leak is located. We provide a free, written, in-person estimate before any work begins so you know the real number for your home.
