Most Cary houses are young enough that their supply pipes are fine, but the older neighborhoods and some 1980s and 1990s homes do reach the point where patching stops making sense. A repipe replaces the interior water lines with PEX or copper, all at once or in sections. Call the number on this page to be connected with a local plumber in Cary.

When patching stops making sense
- Pinhole leaks keep turning up in copper runs, each in a new spot
- Gray polybutylene tubing feeds the fixtures or the water heater
- Hot water pressure is noticeably weaker than cold throughout the house
- A ceiling stain returns after a leak above it was already fixed once
- Fittings in the crawl space or attic show green or white crust
Cary's housing and water system
Census survey data puts the median Cary home at 1999, and only about 12% were built before 1980. Kildaire Farms, the state's first planned unit development, and other early subdivisions hold most of the older houses. Those, along with homes built from the late 1970s into the 1990s, are where a plumber is most likely to find aging copper or polybutylene. A 2005 house with PEX rarely needs anything more than a repair.
The Town of Cary treats Jordan Lake water and uses chloramine most of the year, with a spring switch to chlorine. Its 2025 water quality report shows no lead detected at the 90th percentile and says there are no lead service lines in its system, though about 6,800 of roughly 75,000 connections had a segment of unknown material in the 2024 inventory. Cary generally owns the line from the main to the meter. The line from the meter to the house, and everything inside, belongs to the owner.
What moves the price
A two-story house with three bathrooms needs far more pipe and labor than a single-story ranch. Access counts too: an open crawl space or unfinished attic gives a plumber easy routes, while slab foundations and finished ceilings mean more openings. PEX generally installs faster than copper. The quote should also say whether wall patching and new fixture shutoffs are included, and whether the meter-to-house line is part of the job.
When you call
You'll be connected with an independent plumber who works in Cary. Share the year the house was built, what pipe you can see, and where the leaks have been. Repiping requires a plumbing permit, which the Town of Cary's Inspections and Permits office reviews and issues; the plumber usually applies for it online. Ask for a written scope listing each fixture being reconnected.
