French drain: what moves the price in Kentucky
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.
When Kentucky weather lets you install
Season matters for French drain. For each Kentucky metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Louisville has the longest comfortable season of the metros we cover in Kentucky at 9 months (March through November); Bowling Green has the shortest at 8 (March through June and August through November). Rainfall runs from 48 inches a year in Louisville to 50 inches in Bowling Green.
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.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Louisville | 28 | 89 | 48 | 9: March through November |
| Lexington | 25 | 87 | 50 | 9: March through November |
| Bowling Green | 28 | 90 | 50 | 8: March through June and August through November |
Which Kentucky city is cheapest for French drain?
2 of the 3 metros sit above the statewide midpoint of $1,350, and the top-to-bottom gap is 2%. 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 |
|---|---|---|---|
| Louisville, KY | $600 – $2,100 | $1,350 | +1% |
| Lexington, KY | $600 – $2,100 | $1,350 | +1% |
| Bowling Green, KY | $580 – $2,050 | $1,300 | −1% |

Kentucky labor market for French drain
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 3 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.01 for Kentucky.
Construction laborers (47-2061), 50% of the weighting: a median of $21.98 an hour, 3% below the US median of $22.66. The middle half of them earn between $18.13 and $24.06 an hour. About 13,280 work in the state. That is 66.4 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
For operating engineers and other construction equipment operators (47-2073, weighted 30%) the local median is $27.78 an hour, which is 3% below the national $28.78. The middle half of them earn between $23.58 and $31.59 an hour. BLS counts 7,050 of them working in the state, 35.2 for every 10,000 jobs (US: 30.7), so the local bench is about average.
Pipelayers (47-2151), 20% of the weighting: a median of $28.28 an hour, 20% above the US median of $23.56. The middle half of them earn between $25.91 and $28.29 an hour. About 60 work in the state. That is 0.3 per 10,000 jobs, compared with 2.1 nationally, so expect fewer local crews to bid.
A crew paid at the 75th percentile for construction laborers ($24.06 an hour) would add about $30 to the statewide midpoint; one at the 25th percentile ($18.13) would take off about $60. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,000,360 jobs across Kentucky (May 2025), which is 1.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Construction laborers (47-2061) | 50% | $18.13 | $21.98 | $24.06 | $22.66 | 0.97 | state |
| Operating engineers and other construction equipment operators (47-2073) | 30% | $23.58 | $27.78 | $31.59 | $28.78 | 0.97 | state |

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.
