Local Reviews – Real Feedback from 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.
