Why Bangor prices look the way they do
We price the labor side from BLS wage data for 6 trades: carpenters at 50%, cement masons and concrete finishers at 10%, electricians at 10%, plumbers, pipefitters and steamfitters at 10%, drywall and ceiling tile installers at 10%, roofers at 10%. Weighted together, Bangor wages are 0.93 times the national level. Labor makes up about 66% of the midpoint estimate (67% at national prices).
Materials are scaled with BEA's regional price parity for goods. Bangor is at 97.2 against 100 for the US, so a materials line of $18,000 nationally becomes $17,500 here (midpoint, 300 sq ft). Permits follow the all-items index of 96.5: $480 to $1,950.
Data note: 10% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Bangor. The wage table below marks each row.
The best months for home addition in Bangor
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 digging, grading and setting material in the ground, the comfortable months in Bangor are May through October: 6 of 12. Outside them, January, February, March, April, November and December have an average overnight low at or below freezing (32°F).
In January, February, March, April, November and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 161 days a year with a low at or below 32°F at this station.
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.

Who does the work: Bangor trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 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 0.93.
Carpenters (47-2031), 50% 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.
Cement masons and concrete finishers (47-2051), 10% 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.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $28.92 an hour, 6% below the US median of $30.67. The middle half of them earn between $24.31 and $34.14 an hour. About 220 work in the metro. That is 30.4 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Bangor metro, so we used the Maine statewide median: $28.89 an hour against $28.33 for the US. The middle half of them earn between $25.17 and $30.98 an hour.
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 $2,150 to the midpoint estimate; the 25th percentile takes off about $2,750. That is a swing of roughly 5.0% to 3.9% 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.
