Specs and site conditions that change a Davenport 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
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.
When to schedule composite deck in Davenport
We use NOAA's 1991-2020 climate normals for Davenport (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 Davenport (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.
Davenport gets about 36 inches of precipitation in a normal year. The wettest months are May, June and July (4.8 inches in May). Inside the workable window, March and November are the driest, at 2.3 and 2.3 inches. The station averages about 13 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.

Optional extras in Davenport
Extras are quoted nationally and then scaled to Davenport by the average of the local wage index (1.03) and goods index (0.94), a factor of 0.99. 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.
| Add-on | Local range |
|---|---|
| Add a deck railing (approx. 0.3 ft per sq ft) | $1,750 – $5,300 |

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 Davenport is 1.03 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $29.06 an hour, which is in line with the national $29.12. The middle half of them earn between $23.15 and $35.60 an hour. BLS counts 670 of them working in the area, 37.1 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 $26.14 an hour, 15% above the US median of $22.66. The middle half of them earn between $21.74 and $33.98 an hour. About 1,320 work in the metro. That is 73.2 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($35.60 an hour) instead of the median, the labor line grows by about $1,950. At the 25th percentile ($23.15) it shrinks by about $1,750. The total moves by 10.8% or 9.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 180,450 jobs in the Davenport-Moline-Rock Island area. That makes it the 128th largest of the 300 metros we cover, with 0.12% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $23.15 | $29.06 | $35.60 | $29.12 | 1.00 | metro |
