Where the Billings price comes from

Labor is 60% of the midpoint bill here, against 60% nationally. The mix of trades behind this job is carpenters (80%), construction laborers (20%). We weight each trade's local median wage by that share and compare it with the national median. In Billings the blended ratio comes out at 0.99.

On the materials line, the BEA goods price index for the Billings metro is 96.0 (US = 100). The midpoint materials bill for 300 sq ft comes to $6,900, compared with $7,200 at national prices. Permit and inspection fees are scaled by the broader index (93.5) and land at $45 to $140.

Local wages behind the labor line

Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Billings is 0.99 times the national level.

For carpenters (47-2031, weighted 80%) the local median is $28.34 an hour, which is in line with the national $29.12. The middle half of them earn between $23.84 and $30.83 an hour. BLS counts 530 of them working in the area, 56.5 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.

Construction laborers (47-2061), 20% of the weighting: a median of $23.68 an hour, 5% above the US median of $22.66. The middle half of them earn between $21.42 and $28.31 an hour. About 830 work in the metro. That is 88.5 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.

Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($30.83 an hour) instead of the median, the labor line grows by about $740. At the 25th percentile ($23.84) it shrinks by about $1,350. The total moves by 4.2% or 7.6%, so wages alone rarely explain a quote that is far outside our range.

For context on the local economy, BLS counts 93,800 jobs in the Billings area. That makes it the 213th largest of the 300 metros we cover, with 0.06% of US employment.

Extras are quoted nationally and then scaled to Billings by the average of the local wage index (0.99) and goods index (0.96), a factor of 0.97. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.

When to schedule composite deck in Billings

We use NOAA's 1991-2020 climate normals for Billings Logan Intl Ap (in the city). These are 30-year monthly averages, not forecasts.

March through November is the stretch where exterior installation runs into the fewest weather problems in Billings (9 of 12 months). January, February and December have an average daytime high under 45°F.

In January, February and December the average high stays below 45°F. Sealants, adhesives and some materials, such as vinyl, are harder to install well in the cold, and short daylight cuts the working day.

Billings gets about 14 inches of precipitation in a normal year, including roughly 57 inches of snow. The wettest months are April, May and June (2.4 inches in May). Inside the workable window, August and November are the driest, at 0.9 and 0.6 inches. The station averages about 32 days a year at 90°F or above.

Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Why two Billings quotes can differ

  • Engineering

    Large or complex decks may need a structural engineer at $100-$220 an hour to get a permit.

  • Board grade

    Composite materials run $16-$32 per sq ft and the installed price is $40-$80 per sq ft, including the substructure (HomeGuide).

  • Labor

    Labor for composite is $24-$48 per sq ft, higher than wood because the boards need extra parts and more careful assembly.

Contractors rarely work more than an hour or two from home, so the neighboring metros set a rough ceiling and floor for your quotes. Midpoints for 300 sq ft range from $16,000 to $18,500 across Billings and its five closest metros.
