The best months for composite deck in Harrisburg
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Harrisburg 1 Ne (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 Harrisburg are March through November: 9 of 12. Outside them, 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.
Harrisburg gets about 45 inches of precipitation in a normal year, including roughly 24 inches of snow. The wettest months are July, August and September (4.8 inches in July). Inside the workable window, October and November are the driest, at 3.8 and 2.9 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.

Why two Harrisburg quotes can differ
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.
Drainage
Ground-level decks over poorly draining yards may need $1,000-$4,000 of drainage work first.
Related projects, priced for Harrisburg
Jobs that often go together with composite deck are priced below at their usual sizes, using the same Harrisburg wage and price inputs. Compared with national midpoints, paver patio comes out highest (+5%) and wood deck lowest (−1%); the gap comes from the trades each job uses.

Who does the work: Harrisburg trade wages
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 Harrisburg the blend is 0.97.
Carpenters (47-2031), 80% of the weighting: a median of $27.74 an hour, 5% below the US median of $29.12. The middle half of them earn between $23.14 and $34.00 an hour. About 1,320 work in the metro. That is 39.4 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 20%) the local median is $23.88 an hour, which is 5% above the national $22.66. The middle half of them earn between $22.00 and $27.94 an hour. BLS counts 1,370 of them working in the area, 40.9 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,850 to the midpoint estimate; the 25th percentile takes off about $1,350. That is a swing of roughly 7.6% to 10.4% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
