Rolling Hills and Amerige Heights have slab foundations on graded lots where soil settlement creates recurring slab leak exposure. Copper supply lines in 1960s–1980s Fullerton homes are increasingly showing pinhole leaks as they approach 50+ years of age — accelerated by the city’s very hard water at 350–400 ppm.

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. Fullerton’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 Fullerton 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.
