Why Boise prices look the way they do
Labor is 41% of the midpoint bill here, against 44% 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 Boise the blended ratio comes out at 0.87.
On the materials line, the BEA goods price index for the Boise metro is 96.2 (US = 100). The midpoint materials bill for 300 sq ft comes to $6,050, compared with $6,300 at national prices. Permit and inspection fees are scaled by the broader index (98.4) and land at $50 to $150.
Extras that change the Boise total
Extras are quoted nationally and then scaled to Boise by the average of the local wage index (0.87) and goods index (0.96), a factor of 0.92. 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.
| Add-on | Local range |
|---|---|
| Add stairs (flat) | $1,300 – $2,400 |
When to schedule wood deck in Boise
We use NOAA's 1991-2020 climate normals for Boise Air Terminal (5 miles from the city center). These are 30-year monthly averages, not forecasts.
February through June and September through November are the stretches where exterior installation runs into the fewest weather problems in Boise (8 of 12 months). January and December have an average daytime high under 45°F; July and August have an average daytime high of 90°F or more.
In January 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.
Boise gets about 12 inches of precipitation in a normal year, including roughly 18 inches of snow. The wettest months are January, May and December (1.5 inches in December). Inside the workable window, June and September are the driest, at 0.8 and 0.4 inches. The station averages about 55 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.

Pick a size, pick a tier: wood deck pricing in Boise

Specs and site conditions that change a Boise bid
Height and stairs
A second-story deck needs more structure. New stairs run $1,400-$2,600 installed.
Railing
A wood or vinyl railing adds $20-$60 per linear foot.
Replacement versus new
Deck replacement costs $30-$55 per sq ft because of demolition and haul-away.
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 Boise is 0.87 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $24.45 an hour, which is 16% below the national $29.12. The middle half of them earn between $21.63 and $30.30 an hour. BLS counts 4,080 of them working in the area, 104.1 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 $22.84 an hour, in line with the US median of $22.66. The middle half of them earn between $19.98 and $25.18 an hour. About 4,700 work in the metro. That is 120.0 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 ($30.30 an hour) instead of the median, the labor line grows by about $800. At the 25th percentile ($21.63) it shrinks by about $380. The total moves by 7.6% or 3.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 391,790 jobs in the Boise City area. That makes it the 67th largest of the 300 metros we cover, with 0.25% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $21.63 | $24.45 | $30.30 | $29.12 | 0.84 | metro |
| Construction laborers (47-2061) | 20% | $19.98 | $22.84 | $25.18 | $22.66 | 1.01 | metro |
