A water line leaking under your foundation can run for months before you see it — while the water bill climbs and the damage spreads. Eco-Flow pinpoints slab leaks with electronic detection, then repairs, reroutes, or repipes — with the options and real numbers in front of you before any concrete is touched.
Slab leaks hide under concrete, so the evidence shows up indirectly. If you're seeing one or more of these, it's worth a detection visit — catching it early is the difference between a contained repair and a flooring-and-foundation problem.
The worst way to find a slab leak is to start breaking concrete and hope. We pinpoint the leak first, so when repair work begins, we open exactly one spot — or none at all, if a reroute is the smarter fix.
Detection starts with isolation: we confirm the leak is under the slab and determine whether it's on the hot or cold side using meter testing and line isolation. Then we locate it precisely with electronic acoustic equipment that hears pressurized water escaping underground, supplemented by pressure testing and thermal indicators on hot-side leaks.
Santa Cruz's older housing stock makes this expertise matter: many homes from the 1950s–70s have original soft copper running under the slab, where decades of water chemistry, soil contact, and pipes rubbing against concrete through thermal expansion eventually wear a pinhole through the line. One pinhole in aging under-slab copper is often a preview — which is why we present repair and reroute options honestly, rather than defaulting to the biggest job. For the full picture of how we find hidden leaks of every kind, see our leak detection page.
There's no single right answer; the best fix depends on the pipe's age and condition, where the leak sits, and your flooring. We quote the realistic options side by side rather than pushing one.
Slab leak pricing varies more than almost any other plumbing repair, because the job spans everything from a single accessible reroute to opening concrete under tile. These ranges are an honest baseline — the detection visit produces an exact written quote for your specific situation.
One thing we tell every slab leak customer: factor flooring restoration into the comparison. A slab cut that looks cheaper than a reroute often isn't once the tile or hardwood above it has to be repaired — which is exactly why we quote the options side by side.
| Service | Typical Range |
|---|---|
| Slab leak detection & pinpointing visit | $250–$500 |
| Single-line reroute above the slab | $1,500–$3,500 |
| Direct spot repair, incl. concrete open & patch | $2,000–$4,500 |
| Whole-home repipe (repeat-leak homes) | Quoted by home — see repiping page |
Ranges, not quotes — flooring type, leak depth, and access drive the final number. Detection cost is credited toward the repair when we do the work.
