SLAB LEAK REPAIR IN RUSTON & NORTH LOUISIANA

Noticed a spike in your water bill? You could have a plumbing problem that's causing you to lose water. A slab leak occurs when piping located inside a concrete foundation slab develops a leak.

Slab leaks are among the most frustrating problems a homeowner faces, because repairing a leaking pipe encapsulated inside concrete is a difficult prospect at best. Our experienced technicians use the right tools to locate the leak precisely and repair it with minimal damage to your home.

Signs you have a slab leak

1. Warm spot on a concrete floor — hot water line is leaking. Classic signal
2. Water bill spiked without explanation — 20%+ increase in a month is a hidden leak until proven otherwise
3. Sound of running water when nothing is on — pressurized leak, check the meter
4. Damp baseboards or carpet near an exterior wall — water migrating from slab to wall
5. Mildew smell in the house — water soaking into the subfloor is growing mold
6. Low water pressure house-wide — leak is large enough to affect system pressure
7. Cracks appearing in drywall or floor tile — long-term leak is destabilizing the slab
8. Meter spinning with all fixtures off — definitive sign of a leak somewhere on the supply

How we locate a slab leak

Two tools. Acoustic ground microphone — listens for the high-frequency hiss of pressurized water escaping through a crack. On a typical slab, we can pinpoint the leak within 6–12 inches. Thermal imaging — the heat plume from a hot water leak creates a warm area visible on the floor surface through several inches of concrete. Combined with pressure-isolation testing, we usually have the leak located within 30–60 minutes.

Three repair options — pick based on your situation

Spot repair through the slab — cut a section of concrete directly over the leak, repair the pipe, patch the concrete. Fastest and cheapest at $1,450–$3,850 typical. Best for isolated leaks on otherwise-good pipe. Downside: concrete patch is visible and may repeat if the rest of the pipe is aging.

Line reroute — abandon the under-slab pipe segment, run a new line through the wall, ceiling, or attic to the fixture instead. $1,850–$4,850 typical. No concrete work, no repeat leak risk on that segment. Best for single-fixture slab leaks where the reroute is practical.

Whole-home repipe — if the slab leak is on aging copper that's likely to fail elsewhere, or if you've had slab leaks before, full repipe is the permanent answer. $5,500–$14,000 for PEX. Stops the slab leak problem for 50+ years.

When insurance gets involved

Slab leaks are often covered under homeowner's insurance — the water damage from a sudden leak (drywall, flooring, belongings, dry-out costs) is typically a covered peril. The pipe repair itself isn't covered (that's maintenance). Slab leaks caught early minimize damage and maximize the insurance-covered cleanup. We document everything with photos, thermal imaging, and repair records for your adjuster.
