Leak Detection & Repair in San Antonio

San Antonio's Trusted Water Leak Detection & Repair Company

Water leaks often start small — a faint stain on the ceiling, a musty smell, or a slight spike in your water bill. But left undetected, even the smallest leak can lead to major structural damage, mold growth, and expensive repairs. That's why it's crucial to properly identify and repair water leaks before they spiral out of control. At JDN Water and Fire Restoration, we specialize in accurate, non-invasive leak detection and repair for homes and businesses throughout San Antonio and the surrounding areas. Our certified team not only finds the leak — we pinpoint its source and create a custom plan to fix it right the first time. With 24/7 emergency availability, free evaluations, and a reputation as one of San Antonio's most reliable restoration contractors, we're ready to help protect your property today.

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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:


  1. Water Staining:  Look for stains, damp patches, or puddles around sinks, toilets, or appliances — and especially on walls or ceilings.
  2. 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.
  3. 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.
  4. Damp & Musty Odors:  Persistent musty smells — especially in basements, crawl spaces, or bathrooms — are often a sign of lingering moisture from a leak.
  5. 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.
