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. The fastest and cheapest of the three. 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. A step up in cost from a spot repair. 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. It's the biggest of the three, and it 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.
