Montana seasons and French drain
Season matters for French drain. For each Montana metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Billings has the longest comfortable season of the metros we cover in Montana at 7 months (April through October); Missoula has the shortest at 5 (May through September). Rainfall runs from 14 inches a year in Missoula to 20 inches in Bozeman.
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 |
|---|---|---|---|---|
| Billings | 18 | 87 | 14 | 7: April through October |
| Bozeman | 15 | 82 | 20 | 5: May through September |
| Missoula | 18 | 85 | 14 | 5: May through September |

What construction laborers and the other trades earn in Montana
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 1.03 for Montana.
Construction laborers (47-2061), 50% of the weighting: a median of $23.96 an hour, 6% above the US median of $22.66. The middle half of them earn between $20.80 and $28.24 an hour. About 4,590 work in the state. That is 89.7 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
For operating engineers and other construction equipment operators (47-2073, weighted 30%) the local median is $29.61 an hour, which is in line with the national $28.78. The middle half of them earn between $27.07 and $34.68 an hour. BLS counts 3,750 of them working in the state, 73.3 for every 10,000 jobs (US: 30.7), so the local bench is deeper than average.
Pipelayers (47-2151), 20% of the weighting: a median of $23.12 an hour, in line with the US median of $23.56. The middle half of them earn between $22.83 and $29.89 an hour. About 80 work in the state. That is 1.6 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 ($28.24 an hour) would add about $65 to the statewide midpoint; one at the 25th percentile ($20.80) would take off about $50. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 511,580 jobs across Montana (May 2025), which is 0.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Construction laborers (47-2061) | 50% | $20.80 | $23.96 | $28.24 | $22.66 | 1.06 | state |
