Irvine Slab Leak Detection & Repair
Serving Orange County Since 1929. Here for Irvine Homeowners 24/7.
A slab leak occurs in water piping beneath a concrete foundation. Because the location and condition of the affected pipe shape the repair decision, diagnosis comes before opening the slab or rerouting a line. If you suspect a foundation leak, Pacific Plumbing of Southern California provides slab leak detection and repair in Irvine.
We offer free plumbing estimates and explain the proposed scope before you authorize service. You can reach us through our 24-hour emergency service seven days a week, including weekends and holidays, because foundation leaks don’t wait until Monday.

Post-Tension Slab Construction in Irvine
Nearly every home in Irvine sits on a post-tension slab foundation. These foundations contain steel cables that are tensioned after the concrete cures. Each cable can carry approximately 33,000 pounds of force, making its location an important part of any plan that involves cutting or drilling into the foundation.
The steel tendons must be located before concrete is opened. A slab leak investigation should identify the affected water line and account for the foundation’s construction before repairs proceed. This separates the plumbing diagnosis from the repair method rather than treating every leak beneath concrete the same way.
Slab Leak Warning Signs Inside Your Home
Changes in your water use, flooring, or pressure can point to a concealed supply-line leak. One symptom might have another explanation, but several signs together warrant prompt professional assessment.
Arrange an assessment if you notice:
- Higher water bills: Water use rises without a corresponding change in household activity
- Warm or damp flooring: Tile, hardwood, or another floor surface develops an unexplained warm or wet area
- Running-water sounds: Water can be heard while fixtures and water-using appliances are off
- Hot-water pressure changes: Pressure becomes low or inconsistent at multiple fixtures
- Musty odors: Mold, mildew, or persistent odors develop near floor level
- Unexplained moisture: Pooling water appears without a visible surface source
Our Slab Leak Detection Process for Irvine Homes
We typically begin by confirming that your plumbing system is losing pressure and determining whether the affected line carries hot or cold water. We may use static pressure testing and electronic and acoustic listening equipment to narrow the search area without widespread demolition. Your foundation type also remains part of the repair planning.
The diagnostic methods we use depend on your property’s plumbing layout and the conditions observed during the visit. Once we assess the leak and affected piping, the findings guide whether you need access at one location, a bypass around the damaged section, or evaluation of a broader piping concern.
Before starting, we explain the scope so you understand what the service involves. We communicate throughout the job, protect flooring, fixtures, and personal property in the work area, and clean the space when the service is complete.

Irvine Slab Leak Repair Choices
The appropriate repair alternative depends on the confirmed leak location, the condition of the surrounding piping, your foundation’s construction, and access to the damaged line. A licensed plumbing contractor should assess those factors before recommending work. The principal alternatives include spot repair, rerouting, and partial or full repiping.
Spot Repair
A spot repair addresses one isolated damaged section after the leak location has been confirmed. The work involves reaching the affected section, repairing or replacing it, and restoring the access area. When the pipe is beneath concrete containing tensioned tendons, their locations must be considered before cutting or drilling begins.
This approach is evaluated around the condition of the specific failure point. Evidence of additional leaks or broader pipe deterioration changes that assessment and can make a more extensive alternative worth considering.
Rerouting Around the Slab
Pipe rerouting bypasses the damaged section instead of accessing it through the slab. A replacement supply line follows another accessible path, which might involve walls, ceilings, or attic space depending on your property’s layout. The original leaking section is then taken out of service.
Available routes differ from one home to another. The decision requires consideration of the line being replaced, access points, finish materials, and how the new route connects with the existing plumbing system.
Partial or Full Repiping
Partial repiping replaces a defined portion of the supply system, while full repiping replaces the broader network of affected water lines. These alternatives are evaluated when an inspection finds multiple failure points or deterioration beyond a single isolated section.
A leak beneath the slab doesn’t by itself establish that your entire property needs new piping. The extent of observed pipe damage and the condition of the remaining system determine whether repiping belongs among the repair alternatives.
Irvine Plumbing Permits & Inspections
The City of Irvine generally requires a residential plumbing permit to add, replace, repair, or alter water service, water lines, drains, sewer lines, gas lines, or plumbing fixtures. Required permits include mandatory inspections, with inspection costs included in the permit fee.
An exemption can apply when the work only repairs a leak in an existing pipe and doesn’t replace or rearrange pipes, valves, or fixtures. A reroute, repipe, or other alteration falls outside that limited description and should be evaluated against the applicable permit requirements before the project starts.
California plumbing work must generally be performed under a licensed C-36 plumbing contractor. The final repair scope determines which permit and inspection requirements apply to the project.
