Plumbing Pipe Replacement in South Carolina
Section and branch pipe replacement in copper, PEX, or CPVC. We swap corroded galvanized, pinhole-leaking copper, and undersized runs — matched to your system and pressure-tested.

Pipe replacement saves homeowners thousands compared to a whole-home repipe when only one run has failed. A pinhole leak in a copper line, a corroded galvanized branch feeding a single bathroom, or an undersized run that starves a fixture of pressure are all fixable in isolation — if the plumber can access the run and match it correctly to the rest of the system. We replace failed sections in copper, PEX, and CPVC, transitioning cleanly between materials with the right dielectric fittings so you don't trade one corrosion problem for another.
We will tell you honestly when a section replacement is the wrong call. If the home still runs original galvanized steel throughout, if we're seeing the third pinhole in a year on the same copper run, or if the pipe is buried in slab or behind finished walls where repeated access is destructive, a planned repipe usually beats patching one leak at a time. Our plumbers photograph the failure, check the surrounding pipe, and price both options so you choose with full information.
Every section replacement includes shutting off and draining the affected zone, cutting back to sound pipe, installing new run and fittings, and pressure-testing the repair before we close anything up. Where a leak sat inside a wall or ceiling, we identify the water damage and coordinate the drywall patch. We default to type-L copper or PEX-A for supply work — both far outlast the galvanized and polybutylene they replace.

Is it time for pipe replacement? The signs
Green or white crust on copper
A blue-green stain or white mineral crust on a copper line marks a pinhole leak weeping under the insulation. Once one pinhole appears on a run, others usually follow along the same length.
Brown water when you first open a tap — clearing after a few seconds — is corrosion flaking off the inside of galvanized steel pipe. The pipe is closing up from the inside and the run is due for replacement.
Low pressure at one fixture
When a single sink or shower runs weak while the rest of the house is fine, the branch feeding it is likely corroded down to a fraction of its bore. Replacing that run restores full flow.
Water stains on ceilings or walls
A spreading stain below a bathroom or along a wall cavity points to a supply or drain line leaking behind the finish. The longer it runs, the more the surrounding structure absorbs.
Pipe visibly bulging or weeping
A copper line with a raised blister, or a joint beading water, is at the edge of a full failure. Replacing the section on a schedule beats a burst on the coldest night of the year.
Root causes we repair with pipe replacement
Galvanized corrosion
Galvanized steel pipe corrodes from the inside out, closing up the bore and rusting the water. Homes built before the 1970s that still run original galvanized are on borrowed time.
Pinhole corrosion in copper
Aggressive or acidic water, high velocity, and stray electrical current pit copper from the inside until a pinhole weeps through. It clusters on hot lines and recirculation loops.
Coastal and hard-water attack
Salt-laden coastal air corrodes copper and brass fittings from the outside, while hard-water scale and mineral-aggressive water attack from the inside. Both shorten a supply line's life.
Freeze damage
Water expands about 9% as it freezes, splitting the pipe wall or blowing a joint apart. The failed section has to be cut out and replaced — a patch over a frozen split rarely holds pressure.
Polybutylene and failed old materials
Gray polybutylene supply pipe from the 1980s–90s becomes brittle and fails at the fittings without warning. Any run of it is a candidate for planned replacement before it lets go.

Common pipe replacement questions
Top questions homeowners searching for Pipe Replacement near me ask us:
How is the work backed?
New pipe and fittings carry their manufacturer warranties, and the installation labor is covered by the 10-year workmanship guarantee. Pressure-tested joints that fail because of our install are corrected at no charge.
How long until the new section is done?
An accessible run — under a sink, in a basement, or in an unfinished ceiling — is usually replaced and pressure-tested in 1–3 hours. Runs inside finished walls or slab take longer because of access and patch coordination.
Is a section cheaper than a full repipe?
For an isolated failure, yes — a single-section replacement is a fraction of a whole-home repipe. Once you're patching the same corroded system repeatedly, a planned repipe becomes the better economic call.
Will the repair leak again?
We cut back to sound pipe, use the correct fittings and dielectric transitions, and pressure-test before closing up, so the repair itself is solid. If the surrounding pipe is the same failing material, we'll flag that the rest of the run is on the same clock.
Copper, PEX, or CPVC — what will you use?
We match the material to the system and the location. PEX-A is flexible, freeze-tolerant, and fast to run through walls; type-L copper is rigid and proven for exposed and high-heat runs; CPVC suits specific hot-water and chemical applications. We explain the trade-off before we cut.
