Slab Leak Detection & Whole-House Repipe — Central Arkansas
Slab leak suspected? Old polybutylene or galvanized pipes? Whole-house repipe? Cogan Plumbing detects with sonic and camera before any concrete cracks. PEX or copper repipe done right, sized right, permitted when required.
The signs you have a slab leak
- Water bill spiked with no obvious leak — water going somewhere you can’t see.
- Warm spot on the floor — hot-water-side slab leak.
- Sound of running water when nothing is on — usually under the slab.
- Damp or moldy spot at a baseboard — leak migrating to the edge.
- Foundation cracks worsening — long-term slab leak can shift soil under the foundation.
- Mildew smell that won’t go away — moisture under the slab.
How we find it without breaking the slab
We use sonic leak detection (listens for the pressure leak through the slab) and line tracing with pressure testing (isolates which line and where). We pinpoint the leak before anyone touches concrete. When we do have to cut the slab, it’s one spot, not a guessing-game pattern of holes.
Whole-house repipe — when it’s time
Some houses don’t need a slab repair, they need the whole system replaced. Common signs: polybutylene (gray plastic pipe from the late 70s–90s, known failure), galvanized steel (rust buildup, low pressure, rust-colored water), pinhole leaks in copper (water chemistry attacking the pipe wall), multiple slab leaks in a year (system is failing, individual repairs are throwing money away).
We repipe in PEX (flexible, freeze-tolerant, less labor, lower cost) or copper (longer history, traditional preference) — your call after we walk you through both. Sized to your fixture count and pressure needs. Permitted when the city requires it. Walls patched and primed before we leave.
