How To Detect A Water Leak
Professional leak detection goes far beyond what the naked eye can see. At JDN Water and Fire Restoration, we use a range of advanced tools and techniques to detect leaks in walls, ceilings, slabs, underground lines, and more — without causing unnecessary damage to your property.
Here are the most common leak detection methods we use:
- Thermal Imaging : Infrared cameras detect temperature differences caused by moisture. Our technicians scan surfaces like walls, ceilings, and floors to locate hidden leaks based on heat signatures.
- Moisture Meters: This device measures the moisture content in materials like drywall, wood, or flooring. High readings often indicate an unseen water leak — this is one of the most commonly used and accurate detection tools.
- Pressure Testing: We isolate sections of your plumbing system and pressurize them with air or water. A drop in pressure signals a potential leak that needs further inspection.
- Acoustic Leak Detection: Using sensitive listening equipment, we can hear water escaping through pipes — even behind walls or under concrete. These amplified sounds help us pinpoint the exact location of the leak.
What Are The Warning Signs Of a Leak?
Knowing what to look for can save you thousands in future damage. Here are common warning signs that you may have a water leak on your property:
- Water Staining: Look for stains, damp patches, or puddles around sinks, toilets, or appliances — and especially on walls or ceilings.
- Unusual Water Usage: Monitor your water bill or meter for unexpected spikes in usage. Even a small hidden leak can cause noticeable increases in water consumption.
- Acoustic Noises: If you hear water running, hissing, or dripping when no water is in use, there's likely a hidden leak behind your walls or floor.
- Damp & Musty Odors: Persistent musty smells — especially in basements, crawl spaces, or bathrooms — are often a sign of lingering moisture from a leak.
- Mold Growth: The presence of mold or mildew, especially in areas with no obvious water source, could indicate an ongoing hidden leak.
If you suspect a leak in your home or business, don't wait. Contact the local leak detection experts at JDN Water and Fire Restoration for a fast, professional inspection.
