Weather windows across Delaware
Weather decides when digging and ground work can happen, and Delaware 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.
Dover has 9 comfortable months (March through November), with about 48 inches of precipitation a year.
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 |
|---|---|---|---|---|
| Dover | 28 | 87 | 48 | 9: March through November |
Which Delaware city is cheapest for French drain?
Delaware has one metro in our dataset, Dover, so the statewide and metro figures are close. The state figure uses BLS statewide wages, which include rural areas. 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 |
|---|---|---|---|
| Dover, DE | $580 – $2,050 | $1,300 | −2% |
Wages behind the Delaware number
Delaware'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 1.01 times the national level.
For construction laborers (47-2061, weighted 50%) the local median is $21.90 an hour, which is 3% below the national $22.66. The middle half of them earn between $17.93 and $27.07 an hour. BLS counts 3,240 of them working in the state, 66.8 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Operating engineers and other construction equipment operators (47-2073), 30% of the weighting: a median of $27.89 an hour, 3% below the US median of $28.78. The middle half of them earn between $22.36 and $31.80 an hour. About 1,230 work in the state. That is 25.4 per 10,000 jobs, compared with 30.7 nationally, so expect fewer local crews to bid.
For pipelayers (47-2151, weighted 20%) the local median is $28.00 an hour, which is 19% above the national $23.56. The middle half of them earn between $22.45 and $28.77 an hour.
A crew paid at the 75th percentile for construction laborers ($27.07 an hour) would add about $80 to the statewide midpoint; one at the 25th percentile ($17.93) 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 484,790 jobs across Delaware (May 2025), which is 0.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

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.

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.
