Welcome to The Leak Dr Australia.
I’m John William Hermann, founder of Local Leak Detection Specialist. With over 24 years in plumbing, I specialise exclusively in non-invasive water and gas leak detection across Wollongong, Illawarra, NSW and beyond.
You’ll see real-world leak detection jobs inside new builds, prestige homes, commercial sites and complex properties where water damage has already begun. I break down pressure testing, acoustic listening, thermal imaging and advanced diagnostic investigation without unnecessary destruction.
If you’re a homeowner dealing with rising water bills, damp floors, unexplained moisture or hidden water damage, this channel shows you what’s really happening.
If you’re a tradesman wanting to understand leak detection at a higher level, you’ll see the discipline, process and standards required to do it properly.
