Del Mar's unique geology — bluff-top properties, coastal clay soils, and the gradual earth movement inherent to seaside terrain — creates additional stress on the water supply lines running beneath home foundations. Combined with San Diego's hard water, which accelerates internal copper corrosion, Del Mar homes face elevated slab leak risk compared to inland communities. When a pressurized supply line beneath your foundation develops a pinhole or crack, water seeps continuously into the soil, saturating the ground under your slab and eventually manifesting as foundation movement, floor damage, mold growth, or dramatically increased water bills.Homewerx uses precision detection technology — acoustic microphones that amplify the sound of pressurized water escaping through pipe walls, and infrared thermal imaging that reveals temperature differences on floor surfaces — to locate the exact point of failure without exploratory demolition. Once located, we present repair options based on the leak's location, severity, and the overall condition of your under-slab piping: above-slab reroute through walls and ceilings (eliminates the problem section permanently), localized slab repair for isolated failures, or full above-slab repipe when multiple under-slab lines show deterioration.
