Hidden Sewer & Drain Leaks Cost You — More Than You Think
High Utility Bills – Water you’re not using is escaping underground 24/7.
Structural & Soil Damage – Slab and foundation movement caused by wet ground or erosion.
Insurance Denials – Many carriers won’t cover damage from unresolved or “gradual” leaks.
Major Repair Costs – Cracked pipes under your yard or slab can destroy driveways, floors, and walls.
Don’t wait until it’s too late. If you’re searching for leak detection near me in NJ — we’re ready to help.
According to the American Society of Civil Engineers , the U.S. loses over 6 billion gallons of treated water every day due to hidden pipe leaks — much of it from aging sewer and drain systems.
If you’re trying to find trusted drain or sewer leak detection experts in New Jersey, you’re in the right place. Our team uses cutting-edge, non-invasive equipment to pinpoint underground leaks with zero unnecessary digging and minimal disruption to your home or property.

⭐️ New Jersey’s Leak Detection Reviews
Real feedback from homeowners, plumbers, and property managers across NJ.
I had a hidden water main leak in my home and didn’t even know it until my water bill skyrocketed. Carl from first class leak detection came out the same day, found the leak quickly, and explained everything clearly. Super professional and saved me from major damage. Highly recommend!
We had a major water leak from our attic HVAC unit that damaged our hallway and bedroom below. It was overwhelming, but first class leak detection came through for us. They found the source quickly, cleaned everything up, and set up drying equipment right away. They were so compassionate and professional—especially Selda, who made sure we had all the documentation we needed for insurance. It felt like they truly cared about getting our home back to normal. While this experience overall was stressful, working with them made it a lot easier on us
Had a slab leak in my Freehold home that had me sweating—until these guys showed up. No upselling, no drama, just a technician named Carl who hooked up some gear, found the leak fast, and explained it to me like a normal human. He didn’t treat my house like a demolition zone, either. Clean work, fair price, and zero follow-up hassles. If your floor’s turning into a pool or your water bill’s suspicious, stop overthinking it and call them.
