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

Direct Slab Penetration Repair in New Brunswick, NJ
When a slab leak is directly accessible and localized, direct slab penetration is often the most practical repair method. This involves carefully cutting a small section of your concrete slab to access and repair or replace the damaged pipe section. Our team makes sure the repair is fully compliant with New Jersey plumbing codes and the slab is correctly restored, preventing future issues. We take great care to contain dust and debris during this process in your New Brunswick home.
PEX Repiping for Slab Leaks in New Brunswick, NJ
If multiple slab leaks indicate a systemic issue with your home's original plumbing, a full PEX repipe might be the most cost-effective and durable solution. PEX tubing is flexible, corrosion-resistant, and less prone to leaks caused by foundation shifts, making it a good choice for many homes. We can replace all the water supply lines in your New Brunswick home, providing a brand-new, leak-free plumbing system that will last for decades.
Pipe Rerouting and Repiping in New Brunswick
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 New Brunswick with original copper or galvanized plumbing.
Hot Water Slab Leak Repair in New Brunswick, NJ
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.
Emergency Slab Leak Repair in New Brunswick, NJ
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. Quick action limits flooring damage and soil saturation.
Slab Leak Detection in New Brunswick
We start by shutting off fixtures and watching the meter to confirm a leak. Then we isolate the hot and cold lines to find out 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.

Slab Leak Pipe Rerouting in New Brunswick
For more complex or recurring slab leaks, or when the original piping is badly deteriorated, pipe rerouting is an excellent long-term solution. This method involves abandoning the leaky pipe under the slab and installing new plumbing lines through walls or the attic, bypassing the foundation entirely. This removes future slab leak risks from that particular line and is often preferred for older homes in New Brunswick with aging copper or galvanized pipes.

Frequently Asked Questions About Slab Leak Repair in New Brunswick
The cost of slab leak repair in New Brunswick, NJ can vary widely, usually ranging from $1,000 to $5,000 or more, depending on the leak's location, severity, and chosen repair method. Simple direct access repairs might be on the lower end, while extensive rerouting or tunneling will be higher. We provide a clear, upfront estimate after a thorough inspection.
Yes, many slab leak repairs, especially those involving rerouting or repiping, need permits from the local permitting office to comply with building and plumbing codes. Plumbing work in New Jersey falls under the statewide Uniform Construction Code, and most jobs beyond simple repairs need a permit from the local construction office. GLN Plumbing handles all necessary permitting on your behalf, so your repair is fully compliant.
Homeowner's insurance policies vary, but many cover the cost of damage caused by a sudden and accidental slab leak, although the repair of the pipe itself might not be covered. It is best to check with your insurance provider right away after detecting a leak. We can help provide needed documentation for your claim.
Detection usually takes one to three hours. Spot repairs and reroutes usually take one to two days.
Look for sudden spikes in your water bill, warm spots on your floor, the sound of running water when no fixtures are in use, visible water stains or mildew on baseboards or carpets, and cracks in your foundation. These are clear indicators that you might have a hidden slab leak in your New Brunswick home.
You can check your water meter with all fixtures off and feel floors for warm spots. Finding the exact location requires professional detection equipment.
