Repiping in Chapel Hill, NC

The pipe that tells you it is time

Repiping is the job for a house whose supply lines are failing everywhere at once, and in Chapel Hill that usually means one of two culprits. The first is galvanized steel, standard in homes built before the 1960s, which corrodes and scales from the inside until the interior diameter narrows to a fraction of its original bore. That is why an old home near campus can have weak, discolored water and a third leak in two years, the pipe is rusting shut and springing pinholes as it goes. The second is polybutylene, used in some later-twentieth-century builds, which becomes brittle and fails at the fittings.

The tell that repiping beats another spot repair is repetition. One leak is a repair; a second and third pinhole in the same-age line means the rest is close behind, and each leak detection and patch is money spent on a system that is going to keep failing. At that point a whole-house repipe is the cheaper path, because it ends the cycle instead of extending it.

How a repipe actually goes

A modern repipe replaces the failing supply lines throughout the house with PEX or copper. PEX is flexible, freeze-tolerant and can often be routed with less demolition; copper is rigid, long-proven and preferred in some exposed runs. We lay out which suits your home and budget rather than defaulting to one. The work involves opening access points, running the new lines, tying in each fixture, and then patching, and a good repipe crew plans those access cuts to minimize what has to be rebuilt afterward.

The freeze angle matters in Chapel Hill specifically: rerouting vulnerable lines away from exterior walls and unheated crawl spaces during a repipe is a chance to prevent the next burst pipe rather than just replace old with new in the same cold spot. Soft OWASA water then works in your favor going forward, since the new pipe will not scale up the way it would in a hard-water region. It is a bigger job than a repair, so we scope it carefully and price it honestly before starting.

PEX versus copper, and the week it takes

The two modern repipe materials both work, and the choice is about your house, not dogma. PEX is flexible, shrugs off freezing better because it can expand, and routes through walls with fewer openings, which means less drywall to patch and usually a lower cost. Copper is rigid, has decades of proven service, and is often chosen for exposed runs or where a homeowner simply prefers it. On soft OWASA water either will last, since there is little scale to worry about.

A whole-house repipe is a real project but a contained one, typically a few days of running new lines, tying in fixtures and then patching, planned so your water is only off for short, predictable windows. Doing it also lets us route lines away from the cold spots that cause a burst pipe, so the repipe fixes tomorrow's freeze risk as well as today's leaks.
