Other Illinois jobs that often go with windows
Each project weights the trades differently, so Illinois's wage level does not push every price by the same amount. Compared with the US midpoint, vinyl siding is +17% and front door +10%.

| Patio door | 1 door | $660 – $6,800 | +13% |

Illinois labor market for windows
Illinois'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 1.18 times the national level.
Glaziers (47-2121), 50% of the weighting: a median of $29.73 an hour, 8% above the US median of $27.44. The middle half of them earn between $27.53 and $47.25 an hour. About 1,410 work in the state. That is 2.3 per 10,000 jobs, compared with 3.8 nationally, so expect fewer local crews to bid.
Carpenters (47-2031), 40% of the weighting: a median of $37.98 an hour, 30% above the US median of $29.12. The middle half of them earn between $27.00 and $51.42 an hour. About 19,570 work in the state. That is 32.1 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
For general maintenance and repair workers (49-9071, weighted 10%) the local median is $27.27 an hour, which is 14% above the national $23.84. The middle half of them earn between $21.15 and $33.02 an hour. BLS counts 66,600 of them working in the state, 109.2 for every 10,000 jobs (US: 98.4), so the local bench is about average.
A crew paid at the 75th percentile for glaziers ($47.25 an hour) would add about $850 to the statewide midpoint; one at the 25th percentile ($27.53) would take off about $110. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 6,098,130 jobs across Illinois (May 2025), which is 3.9% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Glaziers (47-2121) | 50% | $27.53 | $29.73 | $47.25 | $27.44 | 1.08 | state |

Basic, standard or premium: Illinois 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).
Basic
$4,900 to $9,350
Standard vinyl single-hung, same openings
Standard
$8,250 to $12,700
Mid-grade vinyl or composite, a few larger units
Premium
$11,600 to $16,100
Fiberglass or wood, large or custom sizes
| Size | Basic | Standard | Premium |
|---|---|---|---|
| a few windows (5 windows) | $2,450 – $4,700 | $4,150 – $6,350 | $5,800 – $8,050 |
| small house (10 windows) | $4,900 – $9,350 | $8,250 – $12,700 | $11,600 – $16,100 |

Why two Illinois 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.
Illinois seasons and windows
Weather decides when exterior installation can happen, and Illinois 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.
Every Illinois metro on the list has 9 comfortable months, though rainfall ranges from 34 inches a year in Chicago to 40 in Springfield.
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.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Chicago | 19 | 85 | 34 | 9: March through November |
| Peoria | 18 | 86 | 38 | 9: March through November |
| Rockford | 15 | 84 | 37 | 9: March through November |
| Champaign | 18 | 85 | 37 | 9: March through November |
| Springfield | 19 | 86 | 40 | 9: March through November |
| Bloomington | 16 | 86 | 39 | 9: March through November |
Illinois metro-by-metro prices
1 of the 6 metros sit above the statewide midpoint of $10,500, and the top-to-bottom gap is 13%. 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.
| Metro | Range (10 windows) | Midpoint | vs. state |
|---|---|---|---|
| Chicago, IL | $5,000 – $16,500 | $10,800 | +3% |
| Springfield, IL | $4,550 – $14,800 | $9,700 | −8% |
| Peoria, IL | $4,550 – $14,800 | $9,700 | −8% |
| Bloomington, IL | $4,550 – $14,800 | $9,650 | −8% |
| Rockford, IL | $4,500 – $14,800 | $9,650 | −8% |
