Idaho Falls: what basic, standard and premium work costs
Three bands are cut from the same cited range and localized for Idaho Falls wages and prices. They overlap on purpose: a good standard job and a modest premium job can cost the same. The grid below prices the same bands at 4 common sizes.
Basic
$11,000 to $15,500
Entry-level composite boards, low deck, simple shape
Standard
$14,300 to $18,800
Mid-grade capped boards with railing and stairs
Premium
$17,700 to $22,100
Premium capped or PVC boards, multi-level, hidden fasteners
| Size | Basic | Standard | Premium |
|---|---|---|---|
| 10x12 (120 sq ft) | $4,450 – $6,250 | $5,800 – $7,600 | $7,150 – $8,900 |
| 12x12 (144 sq ft) | $5,300 – $7,450 | $6,950 – $9,050 | $8,550 – $10,700 |
| 16x20 (320 sq ft) | $11,800 – $16,500 | $15,300 – $20,000 | $18,800 – $23,600 |

Why two Idaho Falls 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.
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 Idaho Falls is 0.88 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $25.07 an hour, which is 14% below the national $29.12. The middle half of them earn between $21.83 and $31.11 an hour. BLS counts 750 of them working in the area, 91.6 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 $22.05 an hour, in line with the US median of $22.66. The middle half of them earn between $18.83 and $26.56 an hour. About 970 work in the metro. That is 118.5 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 ($31.11 an hour) instead of the median, the labor line grows by about $1,800. At the 25th percentile ($21.83) it shrinks by about $960. The total moves by 10.8% or 5.8%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 81,840 jobs in the Idaho Falls area. That makes it the 233rd largest of the 300 metros we cover, with 0.05% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $21.83 | $25.07 | $31.11 | $29.12 | 0.86 | metro |
| Construction laborers (47-2061) | 20% | $18.83 | $22.05 | $26.56 | $22.66 | 0.97 | metro |
| Blended | 100% | 0.88 | |||||
When to schedule composite deck in Idaho Falls
We use NOAA's 1991-2020 climate normals for Idaho Falls Fanning Fld (5 miles from the city center). These are 30-year monthly averages, not forecasts.
March through October is the stretch where exterior installation runs into the fewest weather problems in Idaho Falls (8 of 12 months). January, February, November and December have an average daytime high under 45°F.
In January, February, November 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.
Idaho Falls gets about 10 inches of precipitation in a normal year. The wettest months are April, May and June (1.6 inches in May). Inside the workable window, July and August are the driest, at 0.5 and 0.6 inches. The station averages about 26 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.
