What moves the number
Slab access drives slab-leak pricing — tunneling under the foundation costs more than breaking through concrete. SA's very hard water (~15–20 gpg) shortens water heater life and makes softeners a common add. Older neighborhoods (Monte Vista, King William, Jefferson) may have galvanized or cast-iron lines that turn small jobs into repipes.
How to get an honest quote
Shut off the main before the tech arrives on any leak — it limits damage and the bill. For slab leaks, get detection done as a separate line item and compare reroute vs. tunnel pricing. Ask about permit requirements on water heater installs — SA code requires them.
