Window replacement cost in Delaware

Delaware metro-by-metro prices

Delaware has one metro in our dataset, Dover, so the statewide and metro figures are close. The state figure uses BLS statewide wages, which include rural areas. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

Basic, standard or premium: Delaware prices

Bands overlap on purpose, since a good standard job can cost as much as a light premium one. Below are the three bands for the default size, then a grid from a few windows (5 windows) to whole house (25 windows).

Why two Delaware quotes can differ

• Frame material

  Vinyl windows run $350-$1,500 each installed, fiberglass $400-$2,000, composite $400-$2,300, and wood $800-$3,800 (HomeGuide).

• 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.

If you are planning more than one job in Delaware

Each project weights the trades differently, so Delaware's wage level does not push every price by the same amount. Compared with the US midpoint, patio door is −3% and front door −3%.

Delaware seasons and windows

Weather decides when exterior installation can happen, and Delaware is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.

Dover has 11 comfortable months (February through December), with about 48 inches of precipitation a year.

We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.

What glaziers and the other trades earn in Delaware

Delaware's labor line is priced from 3 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 0.99 times the national level.

Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for Delaware, 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.

Carpenters (47-2031), 40% of the weighting: a median of $28.46 an hour, in line with the US median of $29.12. The middle half of them earn between $23.35 and $36.24 an hour. About 2,250 work in the state. That is 46.4 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.

For general maintenance and repair workers (49-9071, weighted 10%) the local median is $24.11 an hour, which is in line with the national $23.84. The middle half of them earn between $20.87 and $29.89 an hour. BLS counts 3,310 of them working in the state, 68.3 for every 10,000 jobs (US: 98.4), so the local bench is thinner than average.

A crew paid at the 75th percentile for glaziers ($32.03 an hour) would add about $220 to the statewide midpoint; one at the 25th percentile ($22.27) would take off about $250. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.

BLS counts 484,790 jobs across Delaware (May 2025), which is 0.3% of US employment.
