Whole-house repiping replaces the aging water supply pipes running through your home, usually because old galvanized or polybutylene lines are corroding, leaking, or choking your water pressure. In older coastal North Carolina homes, it is one of the highest-value plumbing upgrades you can make.
Your supply pipes stay out of sight and out of mind until the day they do not. Rusty water, a drop in pressure, or a second pinhole leak in a year are all signs the pipe itself is wearing out, not just one fitting. Many older homes in Jacksonville, Wilmington, and the smaller coastal towns still run on pipe materials that have reached the end of their service life, and no amount of spot repair changes that.
What Whole-House Repiping Means
Repiping replaces the supply lines that carry hot and cold water from your main shutoff to every fixture in the house. Instead of patching one failed section and waiting for the next, a repipe swaps out the worn material entirely, usually for modern PEX or copper. It is a bigger job than a single repair, but on a home full of failing pipe it costs less over time than chasing leak after leak.
Two materials drive most repipes in older homes: galvanized steel, which rusts from the inside out over decades, and polybutylene, a gray plastic pipe installed in many homes from the late 1970s into the mid-1990s that became known for failing at its fittings without warning.
The Pipe Materials That Drive a Repipe
Galvanized Steel
Galvanized pipe was standard in older homes for decades. Over time the zinc coating wears away and the steel underneath rusts, which narrows the pipe, drops your pressure, and tints your water brown. Once corrosion takes hold, it spreads through the whole system.
Polybutylene
This gray plastic pipe was common in homes built from the late 1970s into the mid-1990s. It can look fine on the outside while breaking down on the inside, and it tends to fail suddenly at the fittings. If your home is from that era and still has it, repiping is the dependable fix.
Lead Pipe and Lead Solder
Lead pipe and the lead solder used on older copper joints are a health concern, not just a plumbing one. Replacing them removes a source of lead from your drinking water for good.
Signs Your Home May Need Repiping
- Rusty, brown, or metallic-tasting water, especially first thing in the morning
- Water pressure that has slowly dropped across the whole house
- More than one pinhole leak in a year, or repeat leaks in the same lines
- Pipes that knock or bang when you shut off a faucet
- Visible corrosion or flaking on exposed pipe
- An older home that still has its original galvanized or polybutylene plumbing
Why Coastal Homes Are Harder on Pipes
Salt air and high humidity speed up corrosion on metal pipe and fittings, and homes on well water can carry minerals and acidity that wear pipes from the inside. That combination means a coastal home can reach the point of repiping sooner than the same house would inland.
Repiping in Jacksonville, Wilmington, and the Older Coastal Towns
The need shows up most in the areas with the oldest housing stock. Jacksonville has plenty of homes from the era when galvanized and polybutylene were standard, including a lot of older rental and military-area housing. Wilmington’s historic districts carry some of the oldest plumbing on the coast. We handle whole-house repiping across Onslow, Pender, and New Hanover Counties, matching the new pipe material and routing to your specific home.
Start with an honest inspection. Not every leak means a full repipe, and not every old pipe needs replacing today. We look at the material, the condition, and how often the system is failing, then tell you whether a targeted repair or a full repipe is the better use of your money.
When Leaks Keep Coming Back
If you are fixing the same kind of leak again and again, the problem is usually the pipe, not the patch. Our water leak detection service can pinpoint where a hidden leak is coming from and help you decide whether a repair or a repipe makes more sense.

Frequently Asked Questions
How do I know if I need a whole-house repipe or just a repair?
If you are dealing with repeat leaks, falling pressure across the house, or rusty water, the pipe material is usually the issue and a repipe is the lasting fix. A single, isolated leak on otherwise sound pipe often just needs a repair. An inspection settles which one you are facing.
What pipe material do you use for repiping?
We typically repipe with modern PEX or copper, chosen to fit your home, your water, and your budget. Both far outlast the galvanized and polybutylene pipe they usually replace.
Is polybutylene or galvanized pipe a problem in coastal North Carolina homes?
Yes. Galvanized pipe rusts from the inside over decades and polybutylene can fail suddenly at the fittings. Both are common in older coastal homes, and salt air and humidity tend to speed the decline.
Do you offer repiping in Jacksonville, Wilmington, and across the coast?
Yes. Wild Water Plumbing + Septic provides whole-house repiping throughout Onslow, Pender, and New Hanover Counties, plus Cedar Point in Carteret County. Call 910.750.2312 or schedule online.
