About Total Leak Detection
Alejandro Diaz is the owner and founder of Total Leak Detection. He started the company because South Florida needed a specialized diagnostics business dedicated to one thing: locating hidden leaks accurately—without guesswork or unnecessary demolition.
Too often, other plumbers, restoration companies, and insurance professionals could not find tradespeople who truly knew how to find leaks. General plumbing and restoration work is one skill set; systematic leak detection—with the right tools, methods, and training—is another. Total Leak Detection exists to fill that gap.
Today we pair that diagnostic focus with deep plumbing field experience and clear communication. We concentrate on three areas: water leak detection, sewer camera inspections, and plumbing reporting.
Meet Alejandro Diaz — the expert in our videos
Alejandro Diaz is a licensed plumber, the owner and founder of Total Leak Detection, and the face of many of our educational videos. He grew up in the trade—riding along on service calls, troubleshooting in the field, and working as a service plumber for years—and later earned a bachelor’s degree in Business from Florida International University. That combination shapes how Total Leak Detection works: practical, thorough diagnostics and straight answers, with solutions that protect your property without unnecessary tear-out or expense.
His family has run a long-established Miami plumbing business (Hernandez Plumbing Company), founded by his grandfather; that heritage is part of his story, but Total Leak Detection is its own company, built specifically for leak finding and reporting—not general plumbing or remodeling.
