What Is a Slab Leak?

Your home's supply and drain lines run through and beneath the concrete slab that forms your foundation. A slab leak occurs when one of those pipes develops a breach — typically from corrosion, high water pressure, soil movement, or pipe wear over decades. Because the pipe is encased in concrete, the leak can spread for weeks or months before any above-ground symptoms appear.

Fontana's soil conditions — including expansive clay in many neighborhoods — and the region's seismic activity both contribute to the pipe movement and stress fractures that cause slab leaks. The city's hard water supply also accelerates internal corrosion in older copper pipes, making Fontana homes particularly susceptible. If your home was built before 1990, the risk is even higher.

Warning Signs of a Slab Leak in Your Fontana Home

Some slab leaks are obvious — standing water, soaked carpet, a floor that's visibly wet. Many others are subtle. These are the warning signs Fontana homeowners should act on quickly:

• Water bill that jumped 20–50% with no change in habits — unexplained usage spikes almost always point to an active leak somewhere in the system
• Warm or hot spots on your floor — patches of warm tile or hardwood are a classic sign of a hot water supply line leaking beneath the slab
• Sound of running water when all fixtures are off — especially noticeable at night in a quiet house; listen near the floor for best detection
• Damp carpet, buckled hardwood, or warped baseboards at ground level — moisture migrating up through the slab
• Cracks developing in your walls, floors, or foundation — soil erosion caused by escaping water destabilizes the foundation over time
• Mold or mildew odor coming from floors or lower walls — a persistent musty smell without an obvious source
• Water pressure that's dropped noticeably throughout the home — a slow, active slab leak reduces system pressure over time

How We Detect and Repair Slab Leaks in Fontana

Our slab leak process is designed to minimize disruption to your home while achieving a precise, durable repair. Here's what to expect when you call us:

1. 1.Pressure test — we isolate your supply lines and pressure-test them to confirm a slab leak is present and to identify whether it's in the hot or cold supply line
2. 2.Electronic leak detection — using acoustic listening devices and electronic amplification equipment, we pinpoint the exact leak location beneath your slab — often within a few inches — before any concrete is disturbed
3. 3.Targeted access and repair — depending on pipe material, location, and severity, we either open a minimal section of the slab for a direct repair, reroute the affected line above the slab through walls or ceiling (trenchless alternative), or — when multiple pipes are compromised — recommend a full repipe
4. 4.Post-repair pressure test — after the fix, we re-pressurize the line and test it thoroughly to confirm the leak is fully resolved
5. 5.Cleanup and restoration — we restore the work area to its pre-repair condition as completely as possible
