Wilmington
Why Wilmington homes get repiped
In Wilmington, repipe demand tracks the housing eras precisely. Converted rowhouses often contain basement-level apartments with minimal flood protection and shared party-wall plumbing. Historic districts hold brick rowhouses and early-1900s twins with aging galvanized and cast-iron plumbing. Galvanized systems from the mid-20th century are living on borrowed time — local pros can often predict the failure by the neighborhood's build decade.
New Castle County tells the repipe story in its pipes: converted rowhouses often contain basement-level apartments with minimal flood protection and shared party-wall plumbing.. High water table: coastal-plain groundwater keeps basements and crawl spaces chronically damp, stressing sump systems. When the third pinhole appears, the conversation shifts from repair to replacement.

Repiping warning signs
Each of these alone is a repair. Together, they are a repipe. Learn the pattern.
- Two or more pipe leaks within a year or two.
- Rusty, brown, or metallic-tasting water from taps.
- Noticeably low water pressure throughout the house.
- Visible corrosion or flaking on exposed pipes.
- Galvanized steel or polybutylene pipe still in service.
What the pro does on a repipe
A repipe is a project, not a repair call — and it should be planned like one. Here is what a professional repipe covers.
- Full assessment of the existing system: material, age, condition, and failure points.
- A repipe plan: which lines get replaced, in what order, with minimal disruption.
- Replacement with modern piping matched to your home and water.
- New shutoff valves and supply stops at every fixture, as part of the job.
- Pressure testing of the new system before walls close back up.
- Coordination on permits and inspections where the locality requires them.
What to do while you decide
A repipe is a planned project, so you have time to be smart about it. These steps keep you safe and informed meanwhile.
Safe to do now
- Identify your pipe material — a magnet sticks to galvanized steel, not to copper.
- Document leak locations and dates to show the pattern to pros.
- Test water pressure with a hose-bib gauge to quantify the problem.
Stop — call a pro
- Repiping is not a DIY project — permits, pressure testing, and code compliance require a licensed pro.
- Do not cap or abandon old lines inside walls without a plan — dead legs stagnate.
- Disturbing old pipe insulation that may contain asbestos — test first.
What to expect
Knowing the phases takes the fear out of the project. This is how it unfolds.
System assessment: the pro maps your pipe materials, leak history, and pressure to confirm repiping is the right call.
Material and scope plan: PEX versus copper, which lines get replaced, and how the work sequences through the home.
Phased installation: new lines run with minimal openings; water is typically restored each evening.
Patch and test: pressure tests, fixture reconnection, and drywall patching plan for the openings made.
The big decision factors
Size, stories, access, and material choice set the range. Understand them before you compare quotes.
- Home size — bathrooms, stories, and total fixture count.
- Pipe material choice — PEX versus copper.
- Access — slab versus crawl space versus basement.
- How much drywall and finish work the openings require.
- Whether the water heater, main valve, and pressure regulator are replaced too.
