Why Greater Los Angeles Homes Get Slab Leaks

Much of Greater LA sits on expansive clay soil that swells and shrinks with moisture changes, stressing the copper water lines running beneath concrete slabs. Add in hard water, summer heat, and the huge stock of homes built from the 1950s through the 1980s, and slab leaks are one of the most common plumbing problems our technicians see — from Los Angeles to Irvine to Ventura.

How Our Slab Leak Detection Visit Works

Your technician arrives with acoustic listening equipment, a thermal imaging camera, and tracer gas tools. Most visits take 1–3 hours and pinpoint the leak within 1–3 feet — no jackhammering to “find” it. You get written findings and upfront repair options. Detection runs $150–$500 nationally as of 2026 (complex homes up to about $600).
