Whole House Repiping in Wilmington, NC
If your Wilmington home still runs on polybutylene, galvanized steel, or corroded early copper, a whole house repipe replaces every water supply line in one project. Most Cape Fear area homes are built over crawl spaces, which keeps repipe pricing here below the national average: typically $4,000 to $8,000 for PEX in a standard single family home.
A whole house repipe replaces every water supply line in the home in a single project. It is the permanent fix for recurring pinhole leaks, rusty water, low pressure, and the insurance problems that come with failing pipe. Old lines are abandoned in place or removed, and new PEX or copper is run to every fixture.
Signs your home needs repiping
- More than one leak in the past two years, especially pinhole leaks in copper
- Rust colored or metallic tasting water first thing in the morning
- Noticeable pressure drop when two fixtures run at once
- Visible corrosion, green crust, or damp spots on supply lines
- Your insurer flagged your plumbing during renewal or refused coverage
- Grey plastic polybutylene pipe (stamped PB2110) at the water heater or under sinks
Why Wilmington homes need repiping earlier than inland homes
Three local factors push Cape Fear plumbing to fail sooner than the same pipe would inland. First, the building boom of 1978 to 1995 filled Leland, Ogden, Porters Neck, and Hampstead with homes plumbed in polybutylene, a material with a documented failure record that insurers now refuse to cover. Second, salt air accelerates corrosion of galvanized steel and copper in homes near the water, from Wrightsville Beach to Carolina Beach and Kure Beach. Older beach cottages with original galvanized supply lines often show heavy internal rust by year 30. Third, the pre-1970 neighborhoods around downtown, Sunset Park, and Carolina Place still carry original galvanized and early copper that is simply past its service life.
A repipe solves all three problems at once. The old lines are abandoned or removed, and new PEX or copper is run through the crawl space and walls with minimal drywall disturbance.
PEX vs copper for a Wilmington repipe
PEX is the default choice on the coast for good reasons. It does not corrode in salt air, it tolerates our chlorinated municipal water, it flexes instead of bursting, and it costs roughly half of copper installed. Copper remains an option for homeowners who prefer metal piping and a 50 plus year track record, but expect the price to land 60 to 100 percent higher, and know that coastal copper can still develop pinhole leaks from formicary corrosion.
Most licensed plumbers in New Hanover, Brunswick, and Pender County quote both options. For a typical 3 bedroom, 2 bath crawl space home, PEX usually prices between $4,000 and $8,000 while copper runs $8,000 to $15,000.
What a repipe project looks like here
A full repipe of an average Wilmington home takes 2 to 4 days. Day one covers running new lines through the crawl space and up to fixtures. Water is usually off for only a few hours, not the whole project. A New Hanover County plumbing permit is pulled by the licensed contractor, and the county inspects the work before walls are closed. Small drywall openings at fixture locations are patched at the end. Homes on pilings at the beaches follow the same process with the lines run and insulated under the elevated floor.

Frequently Asked Questions
How much does it cost to repipe a house in Wilmington, NC?
Most whole house repipes in the Wilmington area cost $4,000 to $8,000 using PEX. Copper repipes typically run $8,000 to $15,000. Crawl space construction, which is standard here, keeps labor lower than slab markets.
Do I need a permit to repipe in New Hanover County?
Yes. A plumbing permit and inspection are required, and the licensed plumbing contractor handles both. Keep the final inspection record; insurers and future buyers will ask for it.
How long does a whole house repipe take?
Two to four days for most single family homes. Water service is usually interrupted for only a few hours during changeover, so you can stay in the home during the project.
Will insurance pay for repiping?
Insurance generally does not pay to replace aging pipe, but it matters in the other direction: many carriers now decline or surcharge homes with polybutylene or heavily corroded galvanized pipe. A completed repipe with permit records often lowers premiums and restores full water damage coverage.
