The cost depends upon location, depth and access, and if anything has to be moved, such as cabinets, etc. Sometimes the supply pipe can be re-routed above the slab to avoid cutting. If the slab has to be broken out the cost could be $500 to thousands. Best is to contact a plumber to diagnose and provide an estimate. You also might contact your homeowners insurance to see if there is any coverage. You can locate a local plumbing pro here: https://porch.com/mesa-az/contractors.
