Emergency Slab Leak Repair services

The cost of slab leak repair varies by job scope, access conditions, permit requirements, and local labor rates. A verified plumber provides a written estimate covering price, scope, and timeline before any work begins — no obligation.

A licensed plumber uses two primary tools: an acoustic listening device that amplifies the sound of pressurized water escaping a pipe wall, and thermal imaging that identifies warm floor areas above hot-water leaks. Ground-penetrating radar is used for cold-water leaks that don’t produce a thermal signature. Detection typically takes 1–3 hours and may be billed separately from the repair.

(1) Spot repair — jackhammer the slab at the leak point, replace that section, restore the concrete ($800–$2,500). Best when the leak is isolated and pipe condition elsewhere is sound. (2) Reroute — abandon the leaking pipe in the slab and run a new line through the attic or walls ($1,500–$4,000). No concrete cutting; best when the slab run is long or multiple leaks are likely. (3) Full repipe — replace all underslab supply lines ($4,500–$15,000). Recommended after two or more slab leaks in five years or when pipe-wall thickness testing shows system-wide compromise.

Most standard HO-3 policies cover sudden and accidental water damage from a slab leak but exclude the cost of accessing the pipe (concrete jackhammering) and the pipe repair itself. Some policies include service-line endorsements that cover repair cost. Your matched plumber can document the damage and leak source for your adjuster. Review your declarations page for specific exclusions before assuming coverage.

Detection: 1–3 hours. Spot repair: 4–8 hours of work, often extending to two days because concrete needs time to cure before the slab is restored. Reroute: 4–8 hours on a single supply line. Full repipe: 3–5 days. The plumber will give you a specific timeline after detection identifies the leak location and surrounding pipe condition.

Yes, in almost all jurisdictions. Cutting a concrete slab and replacing supply pipe requires a plumbing permit and inspection. The verified plumber pulls the permit, schedules the inspection, and provides closed-out permit documentation. Permit fees range from $85 to $400 depending on the city.
