Leak Detection Technology Comparison

## Technology Comparison Guide

Different situations require different detection approaches. Here is how they compare:

### Thermal Imaging **Best for:** Surface leaks, roof moisture, HVAC issues **Cost:** $300-800 **Accuracy:** 90-95% **Time:** 1-2 hours **Pros:** Non-invasive, visual documentation, quick results **Cons:** Cannot detect through thick materials, requires line-of-sight

### Acoustic Listening **Best for:** Pressurized water line leaks **Cost:** $200-600 **Accuracy:** 85-90% **Time:** 1-3 hours **Pros:** Very effective for main line leaks, relatively quick, cost-effective **Cons:** Requires quiet environment, difficult in noisy areas

### Tracer Gas **Best for:** Under-slab leaks, radiant heating, inaccessible systems **Cost:** $400-1200 **Accuracy:** 98%+ **Time:** 2-4 hours **Pros:** Can find inaccessible leaks, very accurate, safe **Cons:** Specialized equipment needed, requires professional

### Ground Penetrating Radar **Best for:** Subsurface mapping, finding utilities, structural voids **Cost:** $800-2000 **Accuracy:** 90-98% **Time:** 1-3 hours **Pros:** Detailed subsurface imaging, comprehensive data **Cons:** Equipment costly, interpretation requires expertise

### Choosing the Right Technology Consider: location, accessibility, urgency, budget, type of system
