Repiping After Multiple Slab Leaks in Plainfield, NJ
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of repeat slab leaks. We can typically complete a full repipe in two to four days.

Hot Water Slab Leak Detection in Plainfield
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs nonstop and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before marking the spot.
Water and Sewer Line Slab Leaks in Plainfield, NJ
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are equipped to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can appear as wet spots or high water bills in your Plainfield, NJ home. We have specific methods for each.

Our rapid response team is equipped to handle urgent situations, limiting damage and providing timely solutions to protect your home or business from extensive water harm.
Slab Leak Reroutes in Plainfield
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We typically use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is a good fit when the slab is covered in tile or hardwood.
Thermal Imaging for Slab Leaks in Plainfield, NJ
Thermal imaging cameras allow us to visualize temperature differences on surfaces, which can indicate a hidden water leak. As water escapes a hot water line, it creates a clear thermal signature on the concrete slab. This technique is particularly useful for hot water line leaks and helps us narrow down the search area significantly without any physical disruption to your property in Plainfield.
Slab Leak Detection and Repair Cost Comparison in Plainfield, NJ
Slab leak detection typically costs $150 to $450. Direct access repairs usually run $1,000 to $3,000, including concrete patching but not flooring replacement. Reroutes generally cost $800 to $3,500 depending on distance and access. Full repipes cost more, often $4,000 to $15,000, but end the problem permanently.

Non-Invasive Leak Detection in Plainfield, NJ
Our primary goal is to locate your slab leak with the least amount of disruption possible.

Frequently Asked Questions About Slab Leak Detection in Plainfield
Slab leak detection in Plainfield usually costs $150 to $450. Repairs range from about $800 for a simple reroute to $3,000 or more for direct access under finished floors. We provide a written estimate after finding the leak.
We stand by the accuracy of our slab leak detection services. While detection itself is a diagnostic service, we make sure our findings are accurate. Any subsequent repairs performed by GLN Plumbing come with our standard labor and parts warranties, which will be plainly outlined for you.
Many homeowner insurance policies cover the cost of water damage from a sudden or accidental slab leak, and sometimes the cost of accessing the leak for repair. However, coverage varies greatly, so it's important to check your specific policy with your insurance provider.
Warm spots on the floor, the sound of running water with fixtures off, a moving water meter and an unexplained jump in your water bill are common signs. Cracked tile, damp carpet and mildew odors also suggest a slab leak. Call us if you notice any of these.
Many policies cover the cost to access the leak and repair resulting water damage, though the pipe itself may not be covered. Coverage varies by insurer. We provide photos and a written report for your claim.
Once the slab leak is precisely detected, our technician will provide you with a detailed report and discuss the best repair options. These options may include trenchless repair, re-routing the affected pipe or traditional slab excavation and repair. We will then provide a transparent estimate for the repair work.
While you can look for the signs, accurately detecting a slab leak requires specialized equipment and expertise that most homeowners don't have. DIY attempts often lead to more damage or misdiagnosis, making professional detection a more cost-effective and reliable solution in the long run.
Reroutes and repipes often require a plumbing permit, while small direct repairs may not. Requirements vary by city and county. We take care of permits and inspections when needed.
