How much do plumbers make in South Carolina in 2026?

The median plumber in South Carolina earns $53,940 a year, which works out to about $25.93 an hour on a standard 2,080-hour year. That's the midpoint — half the state's plumbers earn more, half earn less. Where you fall on that range depends on experience, employer type, the region of the state you work in, and how much overtime you're pulling.

The bottom quarter of South Carolina plumbers — typically journeymen earlier in their careers or those working for smaller residential outfits — bring in $46,400 or less, which is roughly $22.31 an hour. The top quarter clears $64,000 a year, about $30.77 an hour. That $17,600 spread between the 25th and 75th percentile is significant, and it's largely driven by experience and specialization, not luck.

Plumbing in South Carolina breaks into two major buckets: new construction and service/repair. New construction work ties your hours to building permits and contractor pipelines. The Upstate corridor around Greenville and Spartanburg has seen steady residential and commercial development, which tends to push wages up as contractors compete for licensed journeymen. The Lowcountry — Charleston and the surrounding coast — runs hot on both new construction and service work tied to hospitality and aging infrastructure. Columbia, as the state capital and a university hub, keeps a steady baseline of commercial and institutional work. Plumbers in these metros tend to track toward the 75th percentile faster than those in rural counties where job volume is thinner and fewer employers are bidding for your time.

South Carolina has no statewide union scale on record for plumbers at this time. Most plumbers in the state work under merit-shop or open-shop contractors. That means your raise comes from negotiating directly with your employer, switching to a contractor who pays more, or adding credentials that make you harder to replace.

The state requires a plumber's license through the South Carolina Contractor's Licensing Board. Journeyman plumbers need to log hours and pass an exam. Moving from a journeyman license to a master plumber license is one of the clearest pay levers available — master plumbers who run their own crews or jobs command higher flat rates and, in some shops, a percentage bump on top of their base wage. If you're still in an apprenticeship, the four- to five-year JATC or similar program is the structured path, with wages that step up annually as you accumulate hours.

Overtime is real money in this trade. South Carolina plumbers on active commercial projects or emergency service calls regularly work 50- to 60-hour weeks during peak periods. At the median hourly rate of $25.93, every hour past 40 pays $38.90 at time-and-a-half. A plumber working 10 hours of OT per week for 20 weeks adds roughly $7,780 to their annual take before taxes — enough to push a median earner comfortably into the $60,000 range for that year.

Specialization also shifts the numbers. Plumbers who cross-train in pipefitting, medical gas systems, or fire suppression work expand the number of jobs they qualify for and the rates they can command. Backflow prevention certification is another credential that adds commercial and municipal work to your ticket. These aren't just resume items — they translate directly into jobs that other plumbers can't legally touch.

The BLS OEWS figures here cover wage and salary workers and don't capture self-employed plumbers who bill clients directly. Independent plumbing contractors in South Carolina often charge $75 to $125 or more per hour on service calls and keep a larger share of that than any employee wage suggests. The tradeoff is overhead, liability, and no employer-paid benefits — but for experienced plumbers who build a customer base, the ceiling is higher than what any percentile table shows.

If you're comparing offers across South Carolina employers, the $53,940 median is a solid anchor. An employer offering $48,000 in Greenville or Charleston for an experienced journeyman is on the low side and probably has room to negotiate. An offer at $60,000 or above is strong by state standards and warrants a close look at benefits, truck, and overtime policy before you decide.
