Why Portland prices look the way they do
We price the labor side from BLS wage data for 3 trades: glaziers at 50%, carpenters at 40%, general maintenance and repair workers at 10%. Weighted together, Portland wages are 0.95 times the national level. Labor makes up about 27% of the midpoint estimate (27% at national prices). BLS does not publish this trade for the metro, so we used the Maine statewide median.
Materials are scaled with BEA's regional price parity for goods. Portland is at 97.2 against 100 for the US, so a materials line of $7,100 nationally becomes $6,900 here (midpoint, 10 windows). Permits follow the all-items index of 101.9: $0 to $0.
Data note: 50% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Portland. The wage table below marks each row.
Specs and site conditions that change a Portland bid
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.
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+.
Related projects, priced for Portland
Jobs that often go together with windows are priced below at their usual sizes, using the same Portland wage and price inputs. Compared with national midpoints, vinyl siding comes out highest (+1%) and patio door lowest (−2%); the gap comes from the trades each job uses.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Patio door | 1 door | $590 – $5,900 | −2% |
| Front door | 1 door | $510 – $2,450 | level |
| Storm door | 1 door | $360 – $950 | +1% |
| Vinyl siding | 2,100 sq ft of wall | $8,500 – $25,500 | +1% |

What local crews earn in Portland
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Portland the blend is 0.95.
Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for the Portland metro, so we used the Maine statewide median: $22.97 an hour against $27.44 for the US. The middle half of them earn between $22.16 and $26.79 an hour.
Carpenters (47-2031), 40% of the weighting: a median of $30.91 an hour, 6% above the US median of $29.12. The middle half of them earn between $28.45 and $35.95 an hour. About 2,230 work in the metro. That is 77.3 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For general maintenance and repair workers (49-9071, weighted 10%) the local median is $25.28 an hour, which is 6% above the national $23.84. The middle half of them earn between $22.51 and $29.77 an hour. BLS counts 2,550 of them working in the area, 88.4 for every 10,000 jobs (US: 98.4), so the local bench is about average.
A quick sensitivity check: moving the lead trade (glaziers) from the median to the 75th percentile wage adds about $190 to the midpoint estimate; the 25th percentile takes off about $40. That is a swing of roughly 0.4% to 2.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Portland-South Portland has 288,480 jobs in total (BLS, May 2025), ranking 89th by size among the 300 metros on this site.

Portland weather and the window replacement calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Portland Intl Jetport (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in Portland are April through November: 8 of 12. Outside them, January, February, March and December have an average daytime high under 45°F.
In January, February, March 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.
Portland gets about 48 inches of precipitation in a normal year, including roughly 69 inches of snow. The wettest months are April, October and December (5.3 inches in October). Inside the workable window, July and August are the driest, at 3.4 and 3.6 inches. The station averages about 5 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
