Galvanized steel supply lines rust from the inside out, and the rust closes the pipe the way plaque closes an artery. In the mill-village streets near Woodlawn Avenue and downtown, where many houses date to the early 1900s, that process has had a century to work. The signs are weak shower pressure, rust-colored water after a tap sits unused overnight, and pinhole leaks that keep appearing in new spots. Patching one leak leaves the rest of the narrowing pipe in the walls. A full repipe with modern materials restores pressure and ends the cycle of surprise leaks for good.

Cast-iron drain pipe rarely rusts through. Instead it scales shut from the inside. In the brick ranches built across Mount Holly in the 1960s and 1970s, decades of soap, grease, and mineral film have built a rough crust that snags everything passing through. Drains slow to a crawl, toilets gurgle when the washer runs, and eventually the main line blocks completely. A camera inspection shows exactly where the scale is worst and where the iron is still sound. From there the fix is either a thorough cleaning or replacing the failing sections, depending on how far gone the pipe is.

Roots do not break into sound pipe. They find the joints that time has already loosened and move in. Mount Holly's older sewer laterals, many of them clay or early plastic with bell joints, run under yards full of pines, maples, and oaks. A fine root hair slips into a joint, thickens year by year, and becomes a net that catches paper and waste. Hydro jetting cuts the roots out and scours the line clean. When the same joints keep failing, trenchless renewal or a brand-new lateral ends the cycle of repeat backups.

Water expands when it freezes, and neither copper nor plastic wins that fight. The casualties are almost always the same: the hose bibb on a shaded wall, the supply run through a vented crawl space, or the line feeding an unheated garage. One hard January night is enough to split them, and the leak only shows itself at the thaw. We thaw frozen sections safely, cut out the split pipe, and add insulation and accessible shutoffs. That combination leaves the next cold snap with nothing to burst.

A slab leak is a pressurized water line leaking underneath a concrete foundation. Most of the newer subdivisions near Mountain Island Lake are slab-on-grade, so when a buried copper line develops a pinhole, the clues show up inside the house. Suspect one when a patch of floor feels warm underfoot, you hear water running with every tap closed, or the bill rises without explanation. Electronic listening equipment pinpoints the leak without guesswork. The usual repair is a reroute through walls or ceiling, which fixes the leak without breaking the slab at all.

Low ground near the Catawba keeps the water table high, and crawl spaces on those streets stay damp long after a rain moves through. Standing water under a house rots framing, feeds mold, and rusts everything metal down there, including pipes and hangers. A sump pump with a properly routed discharge line keeps the space dry through the wettest months. We also guard the discharge against freezing, so a January cold snap cannot back the whole system up. A yearly check keeps the pump ready for the next long stretch of rain.
