Homeowners in Union City trust GLN Plumbing for all their residential slab leak repair needs. We understand the challenges of repairing plumbing under occupied homes, and we work to minimize disruption to your daily life. From initial inspection to final clean-up, our team works efficiently and respectfully, providing clear communication every step of the way for your peace of mind.
Slab Leak Detection in Union City
We start by shutting off fixtures and watching the meter to verify a leak. Then we isolate the hot and cold lines to determine which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.
Tunneling Slab Leak Repair in Union City, NJ
In some cases, especially when the leak is under a load-bearing wall or in a hard-to-reach area, tunneling beneath the foundation is the preferred method. This lets our plumbers 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 Union City, NJ.
Pipe Rerouting and Repiping in Union City
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 Union City with original copper or galvanized plumbing.

Slab Leak Reroute in Union City
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is easiest. Reroutes end future leaks in that section of pipe.

Frequently Asked Questions About Slab Leak Repair in Union City
The cost of slab leak repair in Union City can range from $500 for a simple, accessible repair to $5,000 or more for complex rerouting or extensive repiping.

A slab leak specifically refers to a leak in the plumbing pipes embedded within or beneath your home's concrete slab foundation. Other water leaks might occur in exposed pipes, walls, or ceilings, but slab leaks are hidden and often more difficult to detect and repair due to their location.
While not entirely preventable, regular plumbing inspections can help identify potential issues early. Using quality plumbing materials during construction or repiping, and checking any noticeable water pressure changes promptly, can help reduce the risk of slab leaks in your Union City home.
A simple direct slab leak repair can often be completed in a single day. More complex repairs involving pipe rerouting or extensive repiping might take 2 to 5 days, depending on the scope of work and the size of your Union City property. We always aim for efficient service with minimal disruption.
