What nearby projects cost in Bangor
Jobs that often go together with detached garage are priced below at their usual sizes, using the same Bangor wage and price inputs. Compared with national midpoints, garage door comes out highest (−3%) and concrete driveway lowest (−11%); the gap comes from the trades each job uses.

| Garage door | 1 door | $680 – $3,600 | −3% |

What local crews earn in Bangor
The labor line is built from BLS wage data, one trade at a time. This job draws on 5 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 Bangor the blend is 0.92.
Carpenters (47-2031), 45% of the weighting: a median of $27.45 an hour, 6% below the US median of $29.12. The middle half of them earn between $23.29 and $30.70 an hour. About 430 work in the metro. That is 59.5 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $21.35 an hour, which is 6% below the national $22.66. The middle half of them earn between $18.60 and $22.35 an hour. BLS counts 530 of them working in the area, 73.3 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Cement masons and concrete finishers (47-2051), 15% of the weighting: a median of $21.56 an hour, 21% below the US median of $27.41. The middle half of them earn between $17.90 and $24.52 an hour. About 110 work in the metro. That is 15.2 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For electricians (47-2111, weighted 10%) the local median is $30.48 an hour, which is in line with the national $30.38. The middle half of them earn between $28.34 and $37.62 an hour. BLS counts 210 of them working in the area, 29.1 for every 10,000 jobs (US: 48.7), so the local bench is thinner than average.
Roofers (47-2181), 10% of the weighting: a median of $23.14 an hour, 13% below the US median of $26.65. The middle half of them earn between $22.59 and $28.04 an hour. About 120 work in the metro. That is 16.6 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,100 to the midpoint estimate; the 25th percentile takes off about $1,400. That is a swing of roughly 3.4% to 2.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Bangor has 72,270 jobs in total (BLS, May 2025), ranking 255th by size among the 300 metros on this site.

Bangor weather and the detached garage calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Bangor Intl Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For pouring concrete, the comfortable months in Bangor are May through September: 5 of 12. Outside them, January, February, March, April, October, November and December have an average overnight low of 40°F or below.
The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.
Bangor gets about 42 inches of precipitation in a normal year, including roughly 75 inches of snow. The wettest months are June, October and November (4.6 inches in October). Inside the workable window, July and August are the driest, at 3.2 and 3.1 inches. The station averages about 6 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.
