What a repipe job covers
Every repipe we quote includes the full scope below.

Work order
Repiping- Full supply line replacement: Every hot and cold supply line from the main shutoff to each fixture gets replaced with new copper pipe or PEX tubing. No splicing into old pipe, no partial runs left behind.
- Fixture shutoff valves: New quarter-turn shutoff valves at every toilet, sink, and appliance. Old gate valves seize up and fail when you need them most. These are the ones you can actually turn by hand.
- Permit and inspection: We pull the plumbing permit through Charleston County and meet the inspector on site. You get the signed inspection card, which matters at resale and for insurance.
- Pressure test and purge: We pressurize the new system with a gauge and hold it to confirm zero drop before closing walls. Then we purge air from every line and test hot and cold at each fixture.
- Floor and fixture protection: Drop cloths, plastic sheeting, and taped-off cabinets along every path we use. We move furniture as needed and clean the work area before we leave.
- Old pipe haul-away: All removed galvanized, polybutylene, or copper pipe leaves with us. We do not leave scrap in your crawlspace or a pile in your yard.

What repiping charleston SC actually involves
A repipe is not glamorous work, but it is the job that ends the leaks for good. We do it once, we do it to code, and we leave your house clean.
Repiping charleston SC means replacing every supply line in your home, not just the section that failed. We cut out the old galvanized steel or polybutylene, run new copper pipe or PEX tubing through the same chases, and tie it back into your fixtures, water heater, and main shutoff. That includes new brass fittings, shutoff valves at each fixture, and a pressure test before we close anything up. It is a full-day to multi-day job depending on square footage and how many fixtures you have.
Most Charleston homes built before 1980 still have galvanized lines that have rusted from the inside out. You see it as brown water in the morning, low water pressure at the second-floor shower, or a pinhole leak that keeps coming back. A whole home repipe charleston SC solves all of it at once instead of chasing one repair after another. If you are searching for repiping near me charleston SC, we serve the whole county and can walk your crawlspace the same week you call.

How our repipe process runs
Every repipe follows the same five stages. You know what is happening each day, who is in your house, and when the water comes back on.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Used for copper pipe joints. We sweat every fitting clean and pressure-test the run before closing any wall.
Cuts copper and PEX square so fittings seat properly. No hacksaw burrs inside the line.
Holds the new system under test pressure to confirm zero drop. This is the step that catches a bad joint before drywall goes back up.
Finds hidden leaks behind walls and under slabs before we quote the repipe scope, so you are not paying to replace sound pipe.
When Charleston homeowners repipe
A 1950s West Ashley ranch with original galvanized pipe and a second pinhole leak this year.
We walk the crawlspace, confirm the pipe is failing in multiple spots, and quote a full PEX repipe.
HomesA downtown Charleston home under contract where the inspection flagged polybutylene supply lines.
We schedule the repipe inside the due-diligence window, pull the permit, and coordinate the inspection so closing is not delayed.
HomesA James Island rental property where two units had burst pipes last winter.
We repipe both units with PEX, replace the shutoff valves, and swap the aging water heaters while the lines are open.
Homes and businessesA Mount Pleasant home adding a bathroom and upgrading to a tankless water heater.
We run the new supply lines, upsize the gas line for a Navien unit, and tie the addition into the repiped system.

How repiping runs in Charleston
Charleston has a plumbing problem most cities do not: a mix of very old housing stock, high humidity, and salt air. Peninsula homes from the 1920s still have galvanized lines that have been patched for decades.
Harleston Village
Historic homes with heart pine floors and tight crawlspaces. We route new lines to avoid opening finished floors and protect original trim during the job.
West Ashley
Mostly 1960s and 70s ranches with original galvanized or polybutylene. These are our most common full repipes and typically finish in two to three days.
James Island
Raised homes with accessible crawlspaces make repipes faster. We still check for flood-line corrosion on the lower runs before quoting.

PhotoWest Ashley ranch, full PEX repipe
Before: A 1972 ranch with original galvanized pipe. Two pinhole leaks in 18 months, brown water in the morning, and a second-floor shower that barely ran. The homeowner was patching drywall every spring.
After: Full PEX repipe completed in three days. Water pressure at the upstairs shower measured 58 psi after the cutover. No leaks at the one-year mark, and the county inspection passed first time.
Harleston Village copper repipe
Before: A 1925 home with a mix of galvanized and patched copper. The inspection report flagged polybutylene in the addition, and the buyer's lender wanted it documented before closing.
After: Copper repipe with new shutoff valves at every fixture, completed in four days. Only two small wall sections opened and patched.
James Island duplex repipe
Before: Two rental units with burst pipes from a hard freeze. Both had original polybutylene and aging water heaters. The landlord was losing rent during repairs and getting emergency calls every winter.
After: Both units repiped with PEX in five days total, water heaters replaced with new Bradford White tanks, and shutoff valves upgraded. Tenants were without water for a few hours per unit, not days.
Problems a repipe solves for good
Most Charleston repipe calls start with one of these four issues.
Brown or rusty water at the tap
Rust from corroded galvanized pipe ends up in your glass, your laundry, and your water heater. It stains fixtures and shortens appliance life.
Low water pressure upstairs
Mineral buildup narrows old pipe to a fraction of its original diameter. Showers turn into a trickle and appliances take forever to fill.
Pinhole leaks every few months
Each leak means drywall repair, water damage risk, and another service call. The pipe is failing in multiple spots, so patching one just moves the problem.
Polybutylene pipe in a 1980s-90s home
Polybutylene gets brittle and fails without warning, often at the fitting. Insurance carriers increasingly refuse to cover homes that still have it.
Why homeowners repipe instead of patch
A repipe is the difference between fixing the same pipe every spring and never thinking about your water lines again. Here is what you actually get.
Water pressure restored
Galvanized pipe narrows to a pencil-width opening after 40 years of rust. New copper or PEX restores full flow to every fixture.
No more surprise leaks
Pinhole leaks in old steel show up at 2 a.m. behind a kitchen wall.
Cleaner water at the tap
Rust and sediment from corroded pipes end up in your glass and your water heater.
Higher resale value
Charleston buyers and home inspectors flag galvanized and polybutylene plumbing immediately. A documented repipe with permits on file removes that objection.

What Charleston homeowners say
Our 1972 ranch had galvanized pipe and we were getting a pinhole leak every few months. Harborline repiped the whole house in three days with PEX. Water pressure upstairs is night and day. They laid down floor protection, pulled the permit, and the county inspector signed off first pass. Worth every dollar.
We live in a 1920s house downtown with heart pine floors, so I was nervous about a repipe. The crew routed the new copper through the crawlspace and only opened two small wall sections. They patched and painted. The brown water we had dealt with for years is completely gone.
I manage three rentals on James Island and had two burst pipes last winter. Harborline repiped both units with PEX and replaced the shutoff valves. Tenants were only without water for a few hours each. They also swapped the water heater while the lines were open. Straight pricing, no games.
Repiping questions Charleston homeowners ask
Short answers for the first few minutes. The team can cover the rest.
Describe what you are seeing and we will point you to the right next step.
(854) 226-6111A single-story ranch with one bathroom sits at the low end. A three-story Peninsula home with four bathrooms and a crawlspace full of original galvanized pipe sits at the high end. We give you a fixed number after the walkthrough, not a range.
Repiping is necessary when your home still has galvanized steel or polybutylene supply lines, when you are getting two or more pinhole leaks a year, or when water pressure drops noticeably at the second floor. Brown water in the morning and rust stains in fixtures are the other clear signals. If a plumber has told you the pipes are failing in multiple spots, a repipe is cheaper than chasing repairs.
Yes. Whole home repiping is our core service. We replace every supply line from the main shutoff to each fixture, including the runs to your water heater, washing machine, and outdoor spigots. We pull the permit, handle the county inspection, and reconnect every fixture. Most homes are done in two to four working days.
A typical Charleston repipe takes two to four working days from demo to final inspection. A small single-bath home can finish in two days. A larger home with multiple bathrooms, a crawlspace, and an attic run can take four or five. Your water is off only during the cutover, usually a few hours on the final day.
