Plumbing and sewer pipes don't last forever. Homes in Arlington, San Mateo, and the Highlands area were built with galvanized steel or early copper piping that's now 40 to 60 years old, and they're reaching the end of their expected lifespan. Iron pipes corrode from the inside, narrowing the flow and eventually rusting through at a joint or a low point. Add Northeast Florida's humidity and the sandy, shifting soil under a lot of these slabs, and small pipe movements over the decades turn into real cracks. Newer homes in Oceanway and Pecan Park aren't immune either. PVC piping handles ground movement better than metal, but poor original installation or a fitting that was never seated right can still cause a leak years after the final inspection.
We've pulled corroded iron supply lines out of houses in Sandalwood that hadn't been touched since they were built, replacing them with copper or PEX that will outlast the homeowner. In coastal spots like Atlantic Beach, Neptune Beach, and Beach Haven, salt air accelerates corrosion on fittings and valves faster than it would a few miles inland. Out on Black Hammock Island, where lots run larger and plumbing runs longer, a slow leak can go unnoticed for months. Whatever part of Jacksonville you're in, our plumbers know which failure points to check first because we've already seen them fail in a house down the street.
