Expansive clay soils in West and Central Santa Ana cause foundation movement that stresses slab plumbing. Slab leaks are a documented and frequent issue throughout the city. Santa Ana’s 1940s–1970s housing stock has copper supply lines entering their active failure window from hard water corrosion.

Common Questions
Got questions before you call? Here's what Fullerton homeowners most often ask us about Leak Detection.
Slab leaks often show up as warm spots on the floor, the sound of running water when everything is off, a sudden spike in your water bill, or cracks forming in flooring or walls near the foundation. Santa Ana’s older slab homes are particularly prone to copper pipe corrosion beneath the foundation.
In most cases, yes. Our acoustic and thermal detection equipment locates leaks from the surface with high precision, eliminating the need to open walls or floors speculatively. We only access the structure at the confirmed leak point.
Most residential leak detection calls in Santa Ana take 1–2 hours. Slab leak detection may take slightly longer due to the scanning process. We give you a clear location and diagnosis before any repair work begins.
