Why You Should Always Verify Pool Leak Detection Licenses in New Jersey
Many homeowners are surprised to learn that most pool leak divers operating in New Jersey are not licensed contractors. While these individuals may offer quick inspections or cheap “fixes,” they often lack the credentials, insurance, and legal authorization required to perform professional pool leak detection or repair work. When a diver shows up without proper tools or training, they can easily miss serious underground plumbing issues or even cause further damage to your pool system.
Hiring an unlicensed diver may seem inexpensive upfront, but the risks can far outweigh any savings. Without the proper licensing or insurance, homeowners have no protection if damage occurs during a leak inspection or repair. Worse yet, diver-only leak detection methods are often limited to what they can see underwater — leaving hidden leaks in plumbing lines, skimmer fittings, and underground pipes completely undetected. In short, a diver might tell you there’s “no leak,” when in fact, the real issue lies beneath your deck or lawn.
Check Before You Hire
Before hiring anyone for pool leak detection, always take a few minutes to confirm they are a licensed professional. The State of New Jersey provides an official, searchable licensing database where you can verify whether a company or individual holds an active contractor’s license. You can search by name, license type, or business name using the official New Jersey State Licensing Board Verification System.
When reviewing a company, make sure their license is current and valid, and that they are insured to work on residential pool systems. In New Jersey, you cannot obtain a contractor’s license without carrying active liability insurance, so confirming a valid license automatically helps verify that the professional is insured as well. Always ask for proof of both before any work begins — a legitimate company will have no problem providing documentation.
Legitimate pool leak detection professionals use certified pressure testing equipment, electronic listening devices, tracer tones, and advanced diagnostic tools — not just goggles and fins. A licensed company will always provide written reports, clear estimates, and transparent pricing before starting any work.
Protect Your Investment
Your swimming pool is a valuable part of your home — and it deserves to be handled by experts who follow professional standards and state regulations. When you hire a diver-only “leak detector” with no license or insurance, you risk paying twice: once for an incomplete diagnosis and again for the real repair later. Always choose a certified leak detection specialist who stands behind their work, uses the proper tools, and carries full liability coverage.

Quick Tip for New Jersey Homeowners
To verify a professional’s license, visit the official New Jersey State Licensing Board and search by the company or individual name before scheduling any pool work. Remember: you can’t get a license without insurance — so if they’re not licensed, they’re not insured.
By taking this simple step, you can ensure your pool is inspected and repaired by professionals who truly understand how to diagnose and resolve complex leaks — not unlicensed divers relying on guesswork.
