Pipe Rerouting and Repiping in Spokane
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 bypasses the problem area entirely, providing a fresh, durable plumbing line. It is a common solution for aging homes in Spokane with original copper or galvanized plumbing.

Spot Repair Through the Slab in Spokane, WA
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a practical option. We cut a small opening, excavate 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.
Tunneling Slab Leak Repair in Spokane, WA
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 requires skilled excavation and shoring to protect structural integrity throughout the repair process in Spokane, WA.
Emergency Slab Leak Repair in Spokane, WA
A large slab leak can push water up through flooring or into walls quickly. We help you shut off the water and send a technician to isolate the leaking line. Often we can restore water to the rest of the house while we plan the repair. Prompt action limits flooring damage and soil saturation.
Cold Water Slab Leak Repair in Spokane
Cold water slab leaks are harder to feel but still waste water and wet the soil. They often show up as a high water bill or a meter that moves with all fixtures off. We isolate the cold line, locate the leak and repair or reroute it. Fixing cold leaks promptly helps protect your foundation.
Hot Water Slab Leak Repair in Spokane, WA
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 limit wear. Warm floors and higher gas or electric bills are common signs.
Direct Slab Leak Repair in Spokane, WA
When a slab leak is localized and accessible, direct repair is often the most practical solution. This involves carefully jackhammering a small section of your foundation to expose the damaged pipe, then repairing or replacing the compromised section. Our technicians are skilled in careful concrete cutting and restoration, so the repair is effective and the area is professionally restored. We use durable materials designed to hold up to soil movement under the slab.

Electronic Slab Leak Detection in Spokane
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 precision detection minimizes 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 thorough diagnosis of your Spokane home.
