Hidden water and gas leaks can cause costly damage long before you see the signs. At Sydney Underground, we specialise in non-invasive leak detection that pinpoints the problem quickly, accurately, and without drilling or destruction.
Our expert technicians use advanced acoustic and thermal imaging technology to trace leaks in pipes, walls, floors, and underground systems. Whether its a damp patch, an unexpected rise in your water bill, a gas smell, a drop in pressure, we’ll find the cause before it becomes a major issue.
