When to schedule composite deck in Grand Junction
We use NOAA's 1991-2020 climate normals for Grand Junction Walker Fld (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 Grand Junction (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.
Grand Junction gets about 9 inches of precipitation in a normal year, including roughly 18 inches of snow. The wettest months are April, September and October (1.2 inches in September). Inside the workable window, February and June are the driest, at 0.5 and 0.4 inches. The station averages about 68 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.

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 Grand Junction is 0.99 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $28.96 an hour, which is in line with the national $29.12. The middle half of them earn between $23.51 and $32.86 an hour. BLS counts 340 of them working in the area, 50.6 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 $21.51 an hour, 5% below the US median of $22.66. The middle half of them earn between $18.55 and $24.79 an hour. About 570 work in the metro. That is 84.9 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 ($32.86 an hour) instead of the median, the labor line grows by about $1,150. At the 25th percentile ($23.51) it shrinks by about $1,600. The total moves by 6.6% or 9.2%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 67,170 jobs in the Grand Junction area. That makes it the 269th largest of the 300 metros we cover, with 0.04% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $23.51 | $28.96 | $32.86 | $29.12 | 0.99 | metro |
