Where the Dover price comes from
The wage side of the estimate leans on glaziers, who do 50% of the hours on a typical job. Their local median is $27.44 an hour. Add the other trades involved and the blended wage index for Dover is 0.94 (US = 1.00), which puts labor at 27% of the total. BLS does not publish this trade for the area, so we used the national median.
On the materials line, the BEA goods price index for the Dover metro is 96.4 (US = 100). The midpoint materials bill for 10 windows comes to $6,850, compared with $7,100 at national prices. Permit and inspection fees are scaled by the broader index (97.5) and land at $0 to $0.
Data note: 50% of the labor weighting for this project uses a national median because BLS has no published metro figure for that trade in Dover. The wage table below marks each row.

When to schedule windows in Dover
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.

Specs and site conditions that change a Dover bid
Window type
Single-hung and picture windows are cheapest; bay and bow windows can reach $3,000-$8,000+.
Count
Replacing 10 to 15 windows runs $4,500-$22,500; at 25 windows it is $11,250-$37,500.
Permit
Window permits are $50-$200 each, or $400-$600 total for a multi-window job, and are often only needed when you change the opening (HomeGuide). No permit fee is included here because many cities do not ask for one on same-size replacements.
Dover: what basic, standard and premium work costs

Standard vinyl single-hung, same openings
Standard
$7,300 to $11,300
Mid-grade vinyl or composite, a few larger units

Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 3 trades carry the job here, and each is compared with its US median. The weighted result for Dover is 0.94 times the national level.
Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for the Dover metro, so we used the national median: $27.44 an hour against $27.44 for the US. The middle half of them earn between $22.27 and $32.03 an hour.
For carpenters (47-2031, weighted 40%) 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.
General maintenance and repair workers (49-9071), 10% of the weighting: a median of $22.08 an hour, 7% below the US median of $23.84. The middle half of them earn between $18.01 and $28.34 an hour. About 410 work in the metro. That is 60.2 per 10,000 jobs, compared with 98.4 nationally, so expect fewer local crews to bid.
Quotes come from real crews, not medians. If the glaziers on your job are paid at the 75th percentile ($32.03 an hour) instead of the median, the labor line grows by about $220. At the 25th percentile ($22.27) it shrinks by about $250. The total moves by 2.4% or 2.7%, 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.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Glaziers (47-2121) | 50% | $22.27 | $27.44 | $32.03 | $27.44 | 1.00 | US |
| Carpenters (47-2031) | 40% | $22.87 | $25.07 | $32.20 | $29.12 | 0.86 | metro |
| General maintenance and repair workers (49-9071) | 10% | $18.01 | $22.08 | $28.34 | $23.84 | 0.93 | metro |
