Composite deck cost in Dover, DE

Climate in Dover: timing your composite deck job

We use NOAA's 1991-2020 climate normals for Dover (in the city). These are 30-year monthly averages, not forecasts.

February through December is the stretch where exterior installation runs into the fewest weather problems in Dover (11 of 12 months). January has an average daytime high under 45°F.

In January 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.

Dover gets about 48 inches of precipitation in a normal year, including roughly 13 inches of snow. The wettest months are June, August and September (4.9 inches in August). Inside the workable window, February and November are the driest, at 3.1 and 3.4 inches. The station averages about 25 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.

Big cities and small ones price differently, so here is Dover against the 4 metros with the closest total employment.

Why two Dover quotes can differ

• 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.

Dover labor market for composite 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 Dover is 0.88 times the national level.

For carpenters (47-2031, weighted 80%) the local median is $25.07 an hour, which is 14% below the national $29.12. The middle half of them earn between $22.87 and $32.20 an hour. BLS counts 270 of them working in the area, 39.7 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 $22.02 an hour, in line with the US median of $22.66. The middle half of them earn between $18.50 and $24.63 an hour. About 400 work in the metro. That is 58.8 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 ($32.20 an hour) instead of the median, the labor line grows by about $2,100. At the 25th percentile ($22.87) it shrinks by about $650. The total moves by 12.8% or 3.9%, so wages alone rarely explain a quote that is far outside our range.

For context on the local economy, BLS counts 68,080 jobs in the Dover area. That makes it the 265th largest of the 300 metros we cover, with 0.04% of US employment.

Add-ons priced for Dover

Extras are quoted nationally and then scaled to Dover by the average of the local wage index (0.88) and goods index (0.96), a factor of 0.92. 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.
