First Class Leak Detection

That drip you can't find? We can.

A hidden leak doesn't always announce itself with a puddle. Sometimes it's a warm spot on the floor, a meter that won't stop spinning, or a water bill that keeps climbing for no clear reason. That's exactly what our plumbing leak detection team is built for.

Our leak detection service covers slab leak detection, pool leak detection, and underground leak detection, all without cutting into walls or digging up your yard. Here's what you can expect:

👉 Non-invasive locating with thermal imaging and acoustic equipment
👉 Emergency response available 24/7 when it can't wait
👉 Detailed reports with photos and readings for your insurance claim

From Marlboro to Toms River and everywhere in between, we help New Jersey homeowners find the source fast, with a 99.8% success rate to back it up.

Notice the signs of a hidden leak? Book your appointment online and let our team find it before the damage spreads.

Is your pool losing more water than it should this summer?

A beautiful backyard pool like this one takes a lot of water to keep full, and even a small hidden leak can waste thousands of gallons before you notice anything wrong. If you're topping off the water more often than usual, seeing wet spots around the deck, or your water bill has jumped, it may be time for professional pool leak detection.

Our team finds cracks in the pool shell, leaks around skimmers and return lines, and hidden plumbing issues near lights and fittings, all without digging up your landscaping or damaging your patio. We also handle underground leak detection and main water line leak detection for the supply lines feeding your pool and home.

💧 Non-invasive testing with dye, acoustic sensors, and pressure checks
💧 Clear findings with detailed documentation for insurance claims
💧 Fast scheduling, with emergency service available when you need it

Homeowners across Freehold, Manalapan, and the surrounding Monmouth County area count on our leak detection service to protect their pools and properties before small problems turn into major repairs.

If your pool seems to be draining your wallet along with your water, schedule your appointment online today and let us pinpoint the leak for you.

Our leak detection service covers everything from slab leak detection under your foundation to pool leak detection in the backyard.

Using thermal imaging, acoustic sensors, and tracer gas, our water leak detection process locates the problem fast and non-invasively, with a 99.8% success rate.
