Coeur d'Alene weather and the composite deck calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Coeur D'Alene (in the city). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in Coeur d'Alene are March through October: 8 of 12. Outside them, 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.
Coeur d'Alene gets about 25 inches of precipitation in a normal year. The wettest months are January, November and December (3.5 inches in December). Inside the workable window, July and August are the driest, at 0.7 and 0.8 inches. The station averages about 18 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

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

Drainage
Ground-level decks over poorly draining yards may need $1,000-$4,000 of drainage work first.
What local crews earn in Coeur d'Alene
The labor line is built from BLS wage data, one trade at a time. This job draws on 2 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Coeur d'Alene the blend is 0.96.
Carpenters (47-2031), 80% of the weighting: a median of $27.00 an hour, 7% below the US median of $29.12. The middle half of them earn between $23.14 and $30.11 an hour. About 790 work in the metro. That is 109.3 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $24.48 an hour, which is 8% above the national $22.66. The middle half of them earn between $21.40 and $28.20 an hour. BLS counts 1,080 of them working in the area, 149.4 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $920 to the midpoint estimate; the 25th percentile takes off about $1,150. That is a swing of roughly 6.6% to 5.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Coeur d'Alene has 72,280 jobs in total (BLS, May 2025), ranking 254th by size among the 300 metros on this site.
