Slab leak detection in Arizona typically costs $250 to $1,500, separate from the actual repair. Price depends on the detection method, home size, and how much access is needed. Some companies credit the detection fee toward the repair, so ask before scheduling.
Detection locates the leak; repair (rerouting, spot repair, or epoxy lining) is quoted separately.
Ask whether detection is credited toward repair and whether the company provides a written report.
Compare repair approaches, since rerouting and lining differ in cost and disruption.
