Slab Leak Detection & Repair in Huntington Beach, CA

Protect Your Concrete Foundation From Silent Water Leaks

Many homes constructed in Huntington Beach during the 1960s, 70s, and 80s were built on concrete slab foundations with copper water lines running directly beneath the poured slab. Over decades, acidic soil conditions, thermal pipe expansion, and water velocity cause pinhole leaks to form in these buried copper lines.

At Huntington Beach Plumbing Pros, we utilize non-invasive Electronic Acoustic Leak Detection and thermal imaging to pinpoint sub-slab leaks with exact inch-level precision—eliminating the need to blindly hammer through your expensive tile or hardwood flooring.

5 Warning Signs of a Foundation Slab Leak

• Unexplained High Water Bills: Sudden double or triple increases in your monthly water utility bill.
• Warm Flooring Hotspots: Unusually warm areas on your floor or carpet (indicating a hot water line leak under the slab).
• Sound of Running Water: Hearing water rushing through pipes even when all faucets and appliances are turned off.
• Damp Baseboards & Mold Growth: Moisture wicking up drywall edges or damp spots under rug pads.
• Drop in Water Pressure: Noticeable loss of shower or faucet pressure throughout your home.

Our Non-Destructive Repair Solutions

Once we locate the slab leak using ultrasonic listening discs and helium tracing gas, we recommend the most cost-effective repair path:

1. PEX Overhead Bypass (Recommended): We abandon the damaged under-slab copper line and route a high-durability, flexible PEX line through your attic or ceiling space, completely bypassing the foundation.
2. Direct Spot Repair: If the leak is isolated and easily accessible, we perform a precision jackhammer cutout, repair the copper section, re-sleeve the pipe, and restore the slab.
