Charleston
The Charleston angle on repiping
In Charleston, repipe demand tracks the housing eras precisely. Peninsula homes with seawater infiltrating through storm drains and into low basements on sunny-day tides. Historic peninsula: 1700s–1800s structures with layered centuries-old systems — especially vulnerable to water. 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.
Charleston County tells the repipe story in its pipes: peninsula homes with seawater infiltrating through storm drains and into low basements on sunny-day tides.. Aging pipe stock: Charleston Sc's older homes still run galvanized and cast-iron systems that corrode from the inside and fail with little warning. When the third pinhole appears, the conversation shifts from repair to replacement.

When pipes are past saving
Pipes do not fail all at once — they decline, and the symptoms stack up. If your Charleston home shows these, the system is telling you it is time.
- 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.
Whole-home repiping — what's covered
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.
Living with failing pipes
Do not let failing pipes rush you into a bad decision. Handle the interim safely.
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.
How repiping works
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.
