When South Carolina weather lets you install
Weather decides when digging and ground work can happen, and South Carolina is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.
Charleston has the longest comfortable season of the metros we cover in South Carolina at 12 months; Columbia has the shortest at 9 (September through May). Rainfall runs from 44 inches a year in Columbia to 54 inches in Myrtle Beach.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.

South Carolina labor market for French drain
South Carolina's labor line is priced from 3 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 0.89 times the national level.
For construction laborers (47-2061, weighted 50%) the local median is $20.65 an hour, which is 9% below the national $22.66. The middle half of them earn between $17.64 and $23.62 an hour. BLS counts 19,620 of them working in the state, 85.1 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Operating engineers and other construction equipment operators (47-2073), 30% of the weighting: a median of $23.53 an hour, 18% below the US median of $28.78. The middle half of them earn between $21.62 and $27.78 an hour. About 8,160 work in the state. That is 35.4 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
For pipelayers (47-2151, weighted 20%) the local median is $21.72 an hour, which is 8% below the national $23.56. The middle half of them earn between $18.73 and $23.80 an hour. BLS counts 670 of them working in the state, 2.9 for every 10,000 jobs (US: 2.1), so the local bench is deeper than average.
A crew paid at the 75th percentile for construction laborers ($23.62 an hour) would add about $45 to the statewide midpoint; one at the 25th percentile ($17.64) would take off about $45. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,305,080 jobs across South Carolina (May 2025), which is 1.5% of US employment.

French drain cost by metro in South Carolina
3 of the 7 metros sit above the statewide midpoint of $1,250, and the top-to-bottom gap is 6%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (60 linear ft) | Midpoint | vs. state |
|---|---|---|---|
| Hilton Head, SC | $560 – $2,000 | $1,250 | +2% |
| Charleston, SC | $560 – $1,950 | $1,250 | +2% |
| Greenville, SC | $560 – $1,950 | $1,250 | +1% |

| Myrtle Beach, SC | $530 – $1,850 | $1,200 | −4% |

Basic
$550 to $1,100
Shallow yard drain, easy digging
Standard
$970 to $1,500
Standard drain with fabric, gravel and a pop-up outlet
Premium

Deep or long drain, hard soil, dry well or sump discharge
| Size | Basic | Standard | Premium |
|---|---|---|---|
| short run (30 linear ft) | $280 – $550 | $480 – $760 | $690 – $970 |
| side yard (60 linear ft) | $550 – $1,100 | $970 – $1,500 | $1,400 – $1,950 |

Why two South Carolina quotes can differ
Exterior versus interior
A shallow exterior French drain is $10-$35 per linear foot; an interior basement drain is $40-$85 per foot, or $4,000-$17,000 installed (HomeGuide).
Where the water goes
A sump pump adds $500-$1,800 and a dry well $50-$3,000+. Discharging to a storm drain can mean extra permit fees.
Depth and soil
Rocky or clay soil and long trenches raise excavation time.
Crawl space drains
A crawl space French drain is $2,000-$8,000 installed.

Where these numbers come from
Base prices are national ranges from the sources below. We scale labor by local BLS wages, materials by BEA goods prices and permits by the BEA all-items price level. Full method on the methodology page.

Note on derived figures: Materials = 48% of the installed price, from Cost to Renovate's mid-range 'Outdoor Living' category split (44% labor, 48% materials). It is a category average, not a French-drain figure, so the materials line here is a rough one.
