Why two Idaho 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.
How Idaho compares with nearby states
Idaho ranks 23 of 51 (the 50 states plus DC) for French drain, where 1 is the most expensive. The costliest is Hawaii at $1,850 and the cheapest Arkansas at $1,150, both for 60 linear ft at the midpoint. Idaho sits at $1,350. The five states closest by workforce center are listed below.

If you are planning more than one job in Idaho
Each project weights the trades differently, so Idaho's wage level does not push every price by the same amount. Compared with the US midpoint, sod installation is level and sprinkler system −5%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Retaining wall | 200 sq ft of wall face | $7,000 – $13,200 | −2% |
| Gravel driveway | 1,000 sq ft | $2,450 – $10,100 | −1% |
| Sod installation | 1,500 sq ft | $1,500 – $3,300 | level |
| Concrete slab | 400 sq ft | $2,400 – $5,050 | −3% |
| Sprinkler system | 4,000 sq ft of lawn | $3,800 – $9,450 | −5% |
| Inground pool | 450 sq ft | $35,300 – $110,500 | −2% |
Basic, standard or premium: Idaho prices
Bands overlap on purpose, since a good standard job can cost as much as a light premium one. Below are the three bands for the default size, then a grid from short run (30 linear ft) to long run (120 linear ft).
Basic
$600 to $1,200
Shallow yard drain, easy digging
Standard
$1,050 to $1,650
Standard drain with fabric, gravel and a pop-up outlet
Premium
$1,500 to $2,100
Deep or long drain, hard soil, dry well or sump discharge
| Size | Basic | Standard | Premium |
|---|---|---|---|
| short run (30 linear ft) | $300 – $600 | $530 – $830 | $750 – $1,050 |
| side yard (60 linear ft) | $600 – $1,200 | $1,050 – $1,650 | $1,500 – $2,100 |
| long run (120 linear ft) | $1,200 – $2,400 | $2,100 – $3,300 | $3,000 – $4,250 |
When Idaho weather lets you install
Weather decides when digging and ground work can happen, and Idaho 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.
Coeur d'Alene has the longest comfortable season of the metros we cover in Idaho at 7 months (April through October); Idaho Falls has the shortest at 5 (May through September). Rainfall runs from 10 inches a year in Idaho Falls to 25 inches in Coeur d'Alene.
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 |
|---|---|---|---|---|
| Boise | 26 | 93 | 12 | 6: March through June and September through October |
| Idaho Falls | 12 | 87 | 10 | 5: May through September |
| Coeur d'Alene | 26 | 83 | 25 | 7: April through October |
Idaho metro-by-metro prices
1 of the 3 metros sit above the statewide midpoint of $1,350, and the top-to-bottom gap is 4%. 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 |
|---|---|---|---|
| Coeur d'Alene, ID | $630 – $2,200 | $1,400 | +4% |
| Boise, ID | $610 – $2,100 | $1,350 | level |
| Idaho Falls, ID | $600 – $2,100 | $1,350 | level |
What construction laborers and the other trades earn in Idaho
Idaho'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 1.05 times the national level.
For construction laborers (47-2061, weighted 50%) the local median is $22.57 an hour, which is in line with the national $22.66. The middle half of them earn between $19.02 and $26.46 an hour. BLS counts 10,850 of them working in the state, 126.5 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 $29.66 an hour, 3% above the US median of $28.78. The middle half of them earn between $25.28 and $36.25 an hour. About 4,270 work in the state. That is 49.8 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 $28.20 an hour, which is 20% above the national $23.56. The middle half of them earn between $22.88 and $31.35 an hour. BLS counts 280 of them working in the state, 3.3 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 ($26.46 an hour) would add about $60 to the statewide midpoint; one at the 25th percentile ($19.02) would take off about $55. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 857,440 jobs across Idaho (May 2025), which is 0.6% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Construction laborers (47-2061) | 50% | $19.02 | $22.57 | $26.46 | $22.66 | 1.00 | state |
| Operating engineers and other construction equipment operators (47-2073) | 30% | $25.28 | $29.66 | $36.25 | $28.78 | 1.03 | state |
| Pipelayers (47-2151) | 20% | $22.88 | $28.20 | $31.35 | $23.56 | 1.20 | state |

French drain by city in Idaho
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.

- Cost to Renovate: Renovation Labor Report 2026: Where the Money Goes (accessed November 4, 2026)
- BLS Occupational Employment and Wage Statistics, May 2025
- BEA Regional Price Parities, 2024

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.
