Your options

Option 1
The floor is opened only where the leak is, a new section of pipe goes in, and the slab is closed back up.
Right for a first failure in pipework still in good condition, under flooring you are happy to lift.

Option 2
The failed run is capped at both ends and a new line is taken through the walls or attic instead, so the floor stays intact.
The most common choice. Reported jobs run about $4,300 for one side and $7,300 for hot and cold together.
Option 3
Access comes from outside the house, under the edge of the slab, leaving interior floors untouched.
Option 4
The pipe is dried, cleaned and given an epoxy coating on its inner wall that closes small holes.
Works in limited cases only. Ask what happens to sections that were not leaking before you agree.
Option 5
Every supply line under the slab is retired and the house is re-plumbed overhead, usually in PEX.

Repair or repipe
A single pinhole in healthy pipe calls for a repair and nothing more. When a second one appears soon after, treat it as a signal. Once a third shows up, the plumbing has made its own case, and new lines often work out cheaper than chasing each failure as it comes.
Mention on the call whether the house has leaked before. A repeat leak changes what makes sense for slab leak repair in Monrovia, CA, and it is better to know that before spending anything.
