Leak Detection Inspections & Repair
Hidden leaks rarely announce themselves until they’ve already caused damage. Our licensed technicians use thermal imaging, acoustic sensors, and moisture meters to pinpoint the exact source — behind a wall, under a slab, or somewhere in your yard — before recommending a repair. Once the leak is located, we’ll walk you through your repair options rather than just handing you a diagnosis.
Signs You Have a Water Leak
Leaks aren’t always visible. Call us if you notice:
- Unexplained water bill spikes
- Mold or mildew smells
- Low water pressure
- Water stains on ceilings, floors, or walls
- The sound of running water when fixtures are off
- Pooling water near the foundation
- Warm or damp spots on floors
What Is a Slab Leak?
A slab leak happens when a pipe leaks beneath your home’s concrete foundation. Left untreated, it can lead to foundation damage, mold growth, and steadily climbing water bills. Common signs include warm or damp spots on the floor, cracks in walls or flooring, the sound of running water beneath the floor, and an unexplained rise in your water bill. Slab leaks require specialized detection tools and experience to locate and repair properly — this isn’t a DIY fix.

FAQs
Can you detect leaks behind walls or under floors?
Advanced leak detection methods help us detect leaks behind walls and under floors. By utilizing specialized equipment like thermal imaging cameras, acoustic sensors, and moisture meters, we can identify hidden leaks without causing extensive damage to your property. Our skilled technicians will accurately locate the source of the leak, providing you with the necessary information to take prompt action and prevent further damage. Trust us to detect hidden leaks and safeguard your property from potential water damage.
What methods and equipment do you use for leak detection?
We employ a range of cutting-edge methods and equipment for leak detection. This includes thermal imaging cameras to identify temperature variations, acoustic sensors to detect sound anomalies, and helium or electronic leak detectors to pinpoint hidden leaks. We also utilize moisture meters and pressure tests for comprehensive analysis. Our technicians are extensively trained to use these tools to identify leaks, provide you with precise information for targeted repairs, and minimize disruption to your property.
How accurate is leak detection technology?
Leak detection technology is highly accurate, allowing us to locate and identify leaks within your plumbing system. Our advanced equipment and methods enable us to detect even the smallest leaks, whether behind walls, under floors, or in hidden pipes. We can provide accurate and reliable results by using state-of-the-art technology, such as thermal imaging cameras, acoustic sensors, and electronic leak detectors.
How much does leak detection cost?
Cost depends on a few factors:
- Leak type — slab leak detection often requires more specialized tools and expertise than a standard leak
- Detection method needed — whether a sewer or drain inspection camera is required to locate the issue
- Plumbing layout complexity — more complex systems can take longer to fully diagnose
- Immediate repair needs — whether a full repair is needed right after the leak is found
After an in-person inspection, we’ll give you a detailed quote covering parts, labor, and your options.
What should I do if I suspect a hidden leak?
If you’re seeing signs like a rising water bill, damp spots, or the sound of running water with no fixtures on, call us to schedule an inspection rather than waiting to see if it resolves on its own — hidden leaks tend to get more expensive the longer they go undetected. If you’re dealing with a sudden burst pipe instead of a slow hidden leak, see our Frozen & Burst Pipe Repair page for immediate emergency steps.

The service technician came to do the fall/winter maintenance on my heat/AC unit. He was very thorough. Did a great job servicing, and cleaning the unit, and the air cleaner unit. Very courteous and friendly. Definitely a professional technician.
