Climate in Washington: timing your wood deck job
We use NOAA's 1991-2020 climate normals for Washington Reagan Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
August through June is the stretch where exterior installation runs into the fewest weather problems in Washington (11 of 12 months). July has an average daytime high of 90°F or more.
Washington gets about 42 inches of precipitation in a normal year, including roughly 14 inches of snow. The wettest months are May, June and July (4.3 inches in July). Inside the workable window, January and February are the driest, at 2.9 and 2.6 inches. The station averages about 40 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.

Washington labor market for wood deck
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 Washington is 1.00 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $29.23 an hour, which is in line with the national $29.12. The middle half of them earn between $26.62 and $35.56 an hour. BLS counts 13,280 of them working in the area, 42.3 for every 10,000 jobs (US: 43.1), so the local bench is about average.
Construction laborers (47-2061), 20% of the weighting: a median of $22.80 an hour, in line with the US median of $22.66. The middle half of them earn between $20.07 and $27.05 an hour. About 17,710 work in the metro. That is 56.5 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 ($35.56 an hour) instead of the median, the labor line grows by about $860. At the 25th percentile ($26.62) it shrinks by about $350. The total moves by 7.4% or 3.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 3,136,190 jobs in the Washington-Arlington-Alexandria area. That makes it the 6th largest of the 300 metros we cover, with 2.02% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $26.62 | $29.23 | $35.56 | $29.12 | 1.00 | metro |
| Construction laborers (47-2061) | 20% | $20.07 | $22.80 | $27.05 | $22.66 | 1.01 | metro |

Add-ons priced for Washington
Extras are quoted nationally and then scaled to Washington by the average of the local wage index (1.00) and goods index (1.05), a factor of 1.03. 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.
