Last updated: April 2026

Slab leaks occur when water supply or drain lines running beneath your concrete foundation develop cracks, pinhole leaks, or joint failures. These leaks can run undetected for months, wasting water, promoting mold growth, and undermining your foundation. Modern electronic leak detection pinpoints the exact location of the leak so plumbers can access and repair it with minimal concrete removal, or reroute the line overhead if that is more cost-effective.

Slab Leak Detection & Repair Cost in Beverly Hills, CA

Slab leak detection

$200 - $500

Electronic and acoustic detection to pinpoint the exact location of the leak under your concrete slab. This is a specialized skill with specialized equipment. Do not skip this step.

Spot repair (one location)

$800 - $2,500

Jackhammering through the slab at the leak point, repairing or replacing the damaged pipe section, then patching the concrete. The price depends on depth, location (kitchen slab is harder than garage slab), and pipe material.

Pipe reroute (abandon under-slab line)

$1,500 - $4,000

Running a new water line through the walls, ceiling, or attic to bypass the damaged under-slab pipe entirely. More expensive upfront, but eliminates the risk of future slab leaks on that line. Often the smarter long-term choice for older Beverly Hills homes.

Full repipe (all lines rerouted above slab)

$4,500 - $10,000+

If multiple under-slab lines are compromised, a full repipe replaces the entire supply system with new PEX lines routed above the slab. This is a big job (2 to 3 days), but it solves the slab leak problem permanently.

Prices are estimates for the Beverly Hills area based on typical jobs. Your actual cost depends on the specific issue, accessibility, time of day, and materials needed. All plumbers in our network provide upfront pricing before starting work.

Prevention Tips for Beverly Hills Homeowners

Monitor your water bill monthly for unexplained increases

Check your water meter with all fixtures off to detect hidden leaks

Maintain stable water pressure to reduce stress on pipes under the slab

Have copper pipes inspected if your home is over 25 years old

Install a whole-house water leak detection system

Address low-pH or aggressive water conditions that corrode copper

Permit Requirements for Slab Leak Detection & Repair in Beverly Hills

Slab leak repairs in Beverly Hills almost always require a building permit. Whether the plumber is doing a spot repair (jackhammering through the foundation) or a reroute (running new pipe through walls or attic), both involve modifying the plumbing system. The permit ensures the repair meets California Plumbing Code and gets inspected. Some Beverly Hills jurisdictions also require an engineering inspection if the foundation is being cut into. Ask your plumber about the full permit process before work begins.

Questions to Ask Before Slab Leak Detection & Repair in Beverly Hills

“How did you locate the leak?”

Proper slab leak detection uses electronic listening equipment, pressure testing, and sometimes infrared cameras. If a plumber guesses the location without using detection equipment, you risk them jackhammering the wrong spot.

“Spot repair or reroute, which do you recommend and why?”

A spot repair is cheaper ($800 to $2,500) but only fixes that one point. A reroute ($1,500 to $4,000) abandons the under-slab pipe entirely and runs a new line above ground. If the pipe is old copper with multiple weak spots, rerouting prevents future slab leaks.

“Is there more than one leak?”

Copper pipes under a slab deteriorate uniformly. If one spot fails, the rest of the line is probably in similar condition. A pressure test after the first repair can confirm whether the system is holding or if more leaks are likely.

“Will this affect my foundation?”

Prolonged slab leaks can erode the soil under your foundation, causing settling or cracking. If the leak has been going for a while, ask the plumber to look for signs of foundation movement. You may need a structural assessment.
