| Service | Typical Range |
|---|---|
| Slab leak detection | $300 – $600 |
| Spot repair (single leak point) | $1,000 – $3,000 |
| Full repipe / reroute | $3,000 – $8,000+ |
These are general South Bay market ranges, not a guaranteed quote for your specific situation. You’ll get a firm number after detection confirms the leak’s location, before any repair work begins.
What Moves the Price Within Each Range
- Access – a leak under an open room is cheaper to reach than one under a load-bearing wall, kitchen island, or built-in cabinetry
- Flooring above the repair area – tile, hardwood, and carpet all have different removal and replacement costs beyond the plumbing work itself
- Number of leak points – a single confirmed spot costs less than multiple locations in the same slab
- Pipe material and condition – if detection reveals the whole line is failing (not just one spot), that shifts the recommendation toward a reroute, which changes the cost category entirely
- Home size and layout – a reroute’s cost scales with how much new pipe needs to run and how many fixtures it serves
See our slab leak repair page for how we decide between a spot repair and a full reroute, and our slab leak detection page for how the leak gets located in the first place.
Frequently Asked Questions
Is the detection cost separate from the repair cost?
Yes. Detection ($300-$600) confirms and locates the leak; repair is priced separately based on what’s found. Some companies credit part of the detection fee toward repair – ask when you schedule.
Why is a full reroute so much more expensive than a spot repair?
A reroute involves running an entirely new line through the attic or walls and connecting it to every fixture the old line served, which is significantly more material and labor than repairing one section of existing pipe.
Does homeowners insurance typically cover slab leak repair cost?
Coverage varies significantly by policy – some cover damage caused by a sudden leak but not the plumbing repair itself. See our insurance coverage guide for more detail, and confirm directly with your provider.
Can I get a firm price before the repair without paying for detection first?
Not accurately – repair cost depends entirely on the leak’s location, severity, and whether it’s an isolated issue or part of a larger pattern, all of which detection reveals. A repair quote without detection first is a guess.
