When to schedule composite deck in Bloomington
We use NOAA's 1991-2020 climate normals for Normal 4Ne (5 miles from the city center). These are 30-year monthly averages, not forecasts.
March through November is the stretch where exterior installation runs into the fewest weather problems in Bloomington (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.
Bloomington gets about 39 inches of precipitation in a normal year, including roughly 20 inches of snow. The wettest months are May, June and July (4.8 inches in May). Inside the workable window, March and November are the driest, at 2.6 and 2.8 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.

Composite deck: what moves the price in Bloomington
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 Bloomington is 1.25 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $36.28 an hour, which is 25% above the national $29.12. The middle half of them earn between $28.00 and $44.69 an hour. BLS counts 170 of them working in the area, 19.3 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Construction laborers (47-2061), 20% of the weighting: a median of $29.16 an hour, 29% above the US median of $22.66. The middle half of them earn between $21.23 and $37.49 an hour. About 380 work in the metro. That is 43.1 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($44.69 an hour) instead of the median, the labor line grows by about $2,500. At the 25th percentile ($28.00) it shrinks by about $2,450. The total moves by 12.2% or 12.1%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 88,110 jobs in the Bloomington area. That makes it the 222nd largest of the 300 metros we cover, with 0.06% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $28.00 | $36.28 | $44.69 | $29.12 | 1.25 | metro |
| Construction laborers (47-2061) | 20% | $21.23 | $29.16 | $37.49 | $22.66 | 1.29 | metro |
