Slab Leak Detection & Repair in Brentwood, CA

Most Brentwood homes sit on concrete slab foundations, and many built from the 1990s through the 2000s have copper water lines running under or through that slab. East County's clay soils swell when wet and shrink in our hot, dry summers, and that movement, along with hard water and the constant expansion of hot-water lines, wears pinholes in pipe you can't see. A slab leak can run for weeks before anyone notices, showing up only as a higher water bill, a warm spot on the floor, or the meter spinning with every tap off.

Finding it accurately is the whole game. We start by confirming there is a leak and isolating whether it's on the hot or cold side, then locate it with acoustic listening equipment and thermal imaging so we can mark the spot before any flooring comes up. From there you have real choices. A single leak in an accessible spot can often be repaired directly through a small opening in the slab. If the line has already leaked once or the copper is thin, rerouting that line overhead through walls or the attic usually costs less disruption than breaking concrete and avoids the next leak in the same pipe. For homes with repeated leaks, a full repipe is the permanent answer.
