What does leak detection cost in San Diego?

Detection only

Most residential locates in San Diego run $325 – $650. A single-story slab with accessible fixtures sits at the low end. Two stories, tile over a mud bed, a pool loop, or a buried gas yard line requiring bar-holing push toward the high end. Commercial and multi-unit work is quoted per building after a walk-through.

Slab leak repair, spot repair

Once located, opening the slab, repairing the line and patching runs $1,400 – $4,000 depending on depth, finish flooring and whether the failure is on the hot side. Post-tension slabs in newer San Marcos, Santee and eastern Chula Vista tracts sit higher because the opening must be engineered around tendons.

Reroute or repipe

When a line has failed more than once — common in mid-century La Mesa and Old Escondido copper — abandoning the under-slab run and rerouting overhead costs $2,500 – $7,500 for a single line, and $8,000 – $18,000 for a whole-home repipe. In chloride-heavy coastal soils a reroute is frequently the cheaper lifetime decision, because the next pinhole is a question of when.

What actually drives your number

Slab depth and pipe burial, flooring type and restoration scope, single vs. multiple failure points, coastal corrosion history on the street, foundation type, and access. We give you the detection price on the phone and the repair price in writing after the locate — never a range that mysteriously doubles once the floor is open.

Insurance

Many California policies cover the cost of accessing and repairing the damage even when the pipe itself isn't covered. Read does homeowners insurance cover slab leaks before you file, and confirm you're actually looking at a slab leak using the signs of a slab leak checklist. Ready to schedule?
