- Advanced Tools, We use modern acoustic listening devices, thermal imaging cameras and moisture meters for non-invasive leak detection.
- Mold Prevention, Persistent moisture from leaks creates perfect conditions for hazardous mold growth.

Yard and Outdoor Leak Detection in Newark
Leaks in outdoor plumbing, irrigation systems or main water lines buried in your yard can lead to wasted water and landscaping damage. We use ground-penetrating radar and tracer gas detection to locate buried pipes and identify leaks without extensive digging. Our approach minimizes disruption to your lawn and garden, protecting your property's appearance. Detecting these outdoor leaks early can also prevent erosion and potential foundation issues caused by saturated soil, a serious concern for homes in Newark, NJ.

Pinhole Leak Detection in Newark, NJ
Pinhole leaks, often found in copper or PEX piping, are small but can cause significant damage over time, especially behind walls or under floors. We use non-invasive moisture meters to detect elevated humidity levels and thermal cameras to identify cold spots that indicate water. Our plumbers are skilled at tracing these elusive leaks without tearing apart your entire home. Swift action on pinhole leaks prevents extensive drywall damage, mold growth and compromised structural integrity. Hot, humid summers and cold winters put New Jersey plumbing through wide seasonal swings that stress joints, valves and water heaters alike.
Water Meter Leak Testing in Newark
The water meter is the first and simplest leak test. With every fixture and appliance off, a moving leak indicator means water is escaping somewhere. We read the flow rate to estimate how many gallons are being lost. Then we shut off zones one at a time to see which part of the property is losing water.
Slab Leak Detection in Newark
Slab leaks are common in homes on shifting soil and moving foundations. These leaks occur in pipes beneath your concrete slab, often signaled by warm spots on the floor, sudden spikes in your water bill or the sound of running water when all fixtures are off. GLN Plumbing uses dedicated acoustic listening devices and thermal imaging cameras to precisely locate these hidden leaks without destructive guesswork. Early detection is key to preventing major foundation damage.
Water Leak Detection Cost Comparison in Newark, NJ
Water leak detection usually costs $150 to $450 depending on the size of the property. Simple repairs like toilet parts may cost $100 to $300, while service line repairs often run $800 to $3,000. Smart shutoff valves usually cost $500 to $1,500 installed. Stopping even a moderate leak quickly can cover the cost of the test in saved water.
Leak Detection for PEX and Copper Pipes in Newark
Whether your plumbing system uses modern PEX tubing or traditional copper pipes, GLN Plumbing has the expertise to detect leaks in both materials. PEX, while flexible, can be vulnerable to damage from rodents or improper installation, while copper can corrode over time, especially with hard water. Our tools are effective across many pipe materials, ensuring accurate detection regardless of your home's plumbing type.
Emergency Water Leak Detection in Newark, NJ
Some leaks require urgent attention, particularly those causing significant water damage or posing a threat to your property's stability. GLN Plumbing provides emergency water leak detection services throughout Newark, NJ, offering prompt response to urgent situations. Our goal is to quickly find and contain the leak to prevent further damage and begin the necessary repairs as soon as possible, day or night.

Underground Water Line Leak Detection in Newark
Leaks in underground water lines, from your meter to your home, can go unnoticed for extended periods, wasting water and causing yard erosion. Signs include oddly green patches in your lawn, persistent wet spots or a constantly running water meter. GLN Plumbing employs ground-penetrating radar and tracer gas detection methods to accurately map out and pinpoint leaks in buried pipes, allowing for targeted excavation and repair rather than digging up your entire yard.

Frequently Asked Questions About Water Leak Detection in Newark
The cost for water leak detection in Newark usually ranges from $200 to $600, depending on the complexity and location of the leak. This fee covers the use of professional equipment and the expertise required to pinpoint hidden leaks. Any subsequent repair costs would be quoted separately after the leak is identified.
We install smart shutoff valves such as Moen Flo and Phyn, along with wireless leak sensors. These monitor flow and can shut off water when a leak is detected. You get alerts on your smartphone.
If you suspect a slab leak, the first step is to call a professional like GLN Plumbing immediately. Avoid trying to dig or open up the slab yourself, as this can cause more damage. Turn off your main water supply if the leak is severe, and clear the area for our team.
Yes, hard water can contribute to plumbing issues over time. Mineral buildup can accelerate corrosion in pipes, especially older copper or galvanized lines, increasing the likelihood of leaks. Regular maintenance can help limit this.
Older homes in Newark often have galvanized steel pipes, which are prone to corrosion and leaks over time. Polybutylene piping, installed in homes from the 1970s to 1990s, is also well known for premature failure and leaks. While copper and PEX are usually reliable, even they can develop pinhole leaks due to water chemistry or installation issues.
Common signs of a hidden water leak include unexplained high water bills, damp spots on walls or floors, the sound of running water when no fixtures are in use, a musty odor or visible mold growth. Also, a sudden drop in water pressure or changes in your water meter reading when no water is being used can signal a problem.
Yes. A softener stuck in regeneration or with a faulty valve can send water down the drain nonstop. We check softeners as part of our leak detection.
GLN Plumbing stands behind our work. While leak detection itself is a diagnostic service, any subsequent repairs performed by us come with a warranty on both parts and labor. We will provide specific warranty details with your repair quote.
