Professional slab leak detection & repair services for San Diego homes. Expert diagnosis, transparent pricing, code-compliant workmanship.
Slab leaks occur when pressurized water lines running beneath a home's concrete foundation develop cracks or pinholes, allowing water to seep continuously into the ground. In La Jolla, where many homes sit on slab foundations and copper supply lines from the 1950s–1980s are now well into the age range where corrosion failures become common, slab leaks are one of the most serious plumbing threats homeowners face. A slab leak can cause foundation shifting, warped hardwood floors, mold growth in wall cavities, and water bills that spike by hundreds of dollars per month — all before the homeowner realizes there's a problem.Homewerx uses advanced non-invasive detection technology to locate slab leaks without tearing up floors. Our process begins with a pressure test to confirm a leak exists in the supply system, followed by acoustic listening equipment that detects the sound of water escaping under pressure through the pipe wall, and thermal imaging that identifies temperature anomalies on the floor surface created by the leaking water. This precision locating means we know exactly where the leak is before any concrete is cut. Repair options include rerouting the affected line above the slab through walls and ceilings (the most durable long-term solution), localized spot repair through a small slab opening, or full repipe with slab abandonment when multiple under-slab lines show deterioration.

Slab Leak RepairLa Jolla's combination of hard water, aging copper supply lines, and high property values creates the perfect storm for slab leak damage. Hard water accelerates copper corrosion from the inside, causing pinhole leaks that start small and grow over time. Because the pipes are under concrete, there are no visible signs until the leak has been running long enough to cause secondary damage. Common indicators include unexplained increases in your water bill, the sound of running water when all fixtures are off, warm spots on the floor (hot water line leaks), damp carpet or warped flooring, and cracks in walls or foundation. At La Jolla property values, the cost of slab leak repair is a fraction of the damage an undetected leak can cause.
Slab leaks are not routine maintenance — they're emergencies that require immediate attention when detected. However, preventive measures can reduce risk: annual plumbing pressure tests identify developing leaks before they cause damage, whole-home repiping above the slab eliminates under-slab supply lines entirely, and water pressure regulation (keeping pressure below 60 PSI) reduces stress on aging copper. Homes built between 1950 and 1985 with original copper supply lines under the slab should have annual pressure monitoring.
