"John & Anthony came to find a leak in my inground pool , they came with all the latest equipment and within a few hours were Able to pinpoint where the leak was . Great company and 2 good guys who took the time to explain every step of the way!!! Would definitely recommend the company for anyone who may have a problem with their pool 👍👍"

"John and Kay were extremely professional and diligent. Would highly recommend their service."

"John and Anthony came out; had a bunch of high tech equipment. They dove, tested all my returns (I have an attached spa so all in about 14 returns), skimmers, and drains (4). They used gas, ink, and they had sonar but not sure they needed it. They found a leak in a return dedicated to my cleaner that I no longer use. I closed that return and hopefully that is that. We had a really hard time finding a company to work on gunite pools. Happy I found them, John and Anthony were professional, got right to work, and cleaned up. I would definitely recommend them and the company. I have a video of the leak it this is not allowing me to post. Thumbs up.."

"John and Rob were awesome they helped find a leak in our pool within an hour of arriving when other companies couldn’t figure it out. Great job guys !"

"I hired First Class Leak Detection to help me identify a leak that multiple sprinkler companies could not. TechniciansJohn and Jonny C were great. They fully understood the situation and demonstrated their expertise and found the leak. They were also very responsive to my needs as a customer and friendly to deal with. First Class Leak Detection has multiple tools to help identify challenges that other companies cannot. I would recommend them to anybody."

"Found the leak in less than an hour. Fantastic job by Carl and Tyler. Thanks so much!"

"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."
