Slab leak cost in the Upstate
A slab leak is a water line failure under the concrete foundation. It is a high-variance, diagnostic-first job, and detection is billed separately from the repair.
Detect and repair
High variance. Detection is a separate line item. Diagnostic-first; the reroute case is the worst case.
Wide range, needs an inspection to price.
Full range $630 to $10,800.
What drives the price
Two jobs that sound the same can price very differently. Access, urgency, permits, parts, and the condition of the existing system do most of the work. Greenville and the Upstate run a bit below national pricing, so these ranges already lean local.
When to call a pro
A warm spot on the floor, an unexplained water-bill jump, or the sound of running water with everything off are the classic signs. Early detection keeps the cost down.
