Exterior Leak Detection

Find and Stop Outdoor Leaks

Exterior leaks can waste water, damage your foundation, and compromise your landscaping if left untreated. At Medrano Co., we provide professional exterior leak detection services throughout the San Diego, CA area to locate hidden leaks in outdoor plumbing systems quickly and accurately.



Whether the issue is in your irrigation system, main water line, or drainage system, our team uses advanced technology to identify leaks without unnecessary digging or disruption.

What Is Exterior Leak Detection?

Exterior leak detection focuses on identifying leaks in plumbing systems located outside your home or building. These leaks often occur underground or in hard-to-see areas, making them difficult to detect without professional equipment.

Common sources include:

• Main water lines
• Irrigation and sprinkler systems
• Outdoor drainage systems
• Pool and spa plumbing lines
• Hose bibs and exterior fixtures

Our Detection Process

We use non-invasive and highly accurate methods to locate exterior leaks, including:

• Acoustic leak detection to hear underground water movement
• Electronic leak detection for pinpoint accuracy
• Infrared thermal imaging to detect moisture variations
• Pressure testing for system integrity
• Video pipe inspections for underground lines
• Moisture mapping to identify affected areas

Our goal is to locate the leak efficiently while minimizing disruption to your yard, driveway, or foundation.

Signs You May Have an Exterior Leak

Exterior leaks can go unnoticed until they cause visible damage. Watch for these warning signs:

• Unexplained increases in your water bill
• Soggy or unusually green patches in your yard
• Standing water or muddy areas
• Cracks in driveways, walkways, or foundation
• Low water pressure
• Water pooling near your home’s exterior
• Irrigation system losing pressure or efficiency

Addressing these signs early can prevent costly repairs and long-term damage.

Outdoor leaks don’t just waste water—they can also lead to serious property damage. Early detection helps:
