Pipe Rerouting and Repiping in San Jose
For more extensive damage, multiple leaks, or pipes that are too old and corroded to repair reliably, pipe rerouting is a long-term solution. This involves abandoning the leaking line under the slab and installing a new pipe through the walls or attic. This method skips the problem area entirely, providing a fresh, durable plumbing line. It is a common solution for aging homes in San Jose with original copper or galvanized plumbing.

Hot Water Slab Leak Repair in San Jose, CA
Hot water lines leak under slabs more often than cold lines because heat expands and contracts the pipe against concrete and gravel. Mineral scale and constant recirculation can wear the pipe wall faster. We repair the leak or reroute the hot line, and we can adjust recirculation pumps to reduce wear. Warm floors and higher gas or electric bills are common signs.
Tunneling Slab Leak Repair in San Jose, CA
In some cases, especially when the leak is under a load-bearing wall or in a difficult-to-access area, tunneling beneath the foundation is the preferred method. This allows our plumbers to reach the damaged pipe from outside your home, avoiding disruption to your interior floors and finishes. Tunneling spares the interior but calls for skilled excavation and shoring to protect structural integrity throughout the repair process in San Jose, CA.
Spot Repair Through the Slab in San Jose, CA
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a sensible option. We cut a small opening, dig down to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.
Electronic Slab Leak Detection in San Jose
Locating a hidden slab leak takes specialized tools. Our plumbers use sensitive electronic listening devices and thermal imaging cameras to pinpoint the exact location of the leak under your concrete foundation. This precise detection reduces the need for extensive concrete removal, saving you time and money. We can detect leaks in both hot and cold water lines, as well as sewer lines, for a complete diagnosis of your San Jose home.
Slab Leak Repair Cost Comparison in San Jose, CA
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost somewhat more but avoid concrete work and future leaks in that line. Whole-house repipes are the best choice when you have had multiple slab leaks or old copper throughout. We give you clear prices for each option.
Advanced Leak Detection Technology in San Jose
Our commitment to effective slab leak repair includes investing in modern diagnostic technology. We use equipment such as thermal imaging cameras to detect temperature changes caused by leaking hot water lines, and very sensitive acoustic sensors to listen for the sound of escaping water. This technology lets us locate leaks without guesswork, even in the diverse mix of buildings across San Jose.

Sewer Line Slab Leak Repair in San Jose, CA
Slab leaks aren't always about clean water pipes, since sewer lines can also leak under your foundation. These leaks pose significant health risks and can cause extensive damage. We specialize in detecting and repairing sewer line slab leaks, using camera inspections to identify the exact problem area. Our methods restore proper waste removal and prevent contamination in your San Jose, CA property, following health and safety codes.
