Angi's 2026 slab leak guide puts slab leak detection at about $150 to $400, with an average around $280. Repair costs vary much more, depending on whether the leak is spot-repaired through the slab, rerouted through the attic, or addressed with a repipe.

What affects cost in Lakewood homes
- Leak location: under a kitchen or bathroom floor is harder than under a closet.
- Flooring: tile and hardwood cost more to open and restore than carpet.
- Method: spot repair, reroute or repipe.
- Pipe condition: if the original galvanized or copper pipe is failing elsewhere, repairs may not end with one leak.
- Insurance: some policies cover access and damage but not the pipe. Check yours.

Before you pay for detection
Do the meter test in our high water bill guide, and check toilets with a dye test. That rules out the simplest leaks first.
What don't these ranges tell you?
Ranges below are U.S. national figures published by the sources named, with the update dates those sources show, accessed November 11, 2026. They are not quotes and not our prices. Southern California labor and permit costs often sit at or above the middle of national ranges. Your actual price depends on the provider, the job and conditions found on site. National averages blend low-cost and high-cost markets, small and large jobs, and simple and difficult access. They don't include every permit, code update or restoration cost, and they can't account for what a provider finds once the work starts. A provider can only price your job after learning about it.
How do you compare quotes in Lakewood?
- Ask each provider to itemize labor, parts or equipment, the permit, code updates, haul-away and restoration.
- Make sure each quote covers the same scope, so you're comparing like with like.
- Ask what's warrantied and for how long, in writing.
- Ask whether a visit or diagnostic fee applies, and whether it's credited toward the work.
- Check the contractor's license with the California Contractors State License Board.
- Confirm whether the provider will pull the Lakewood permit and arrange inspections.
