What local crews earn in Raleigh
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 Raleigh the blend is 0.86.
Carpenters (47-2031), 50% of the weighting: a median of $24.43 an hour, 16% below the US median of $29.12. The middle half of them earn between $21.31 and $29.01 an hour. About 2,680 work in the metro. That is 36.1 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $22.80 an hour, 17% below the US median of $27.41. The middle half of them earn between $20.96 and $27.56 an hour. About 870 work in the metro. That is 11.7 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 $27.31 an hour, which is 10% below the national $30.38. The middle half of them earn between $23.44 and $29.72 an hour. BLS counts 3,740 of them working in the area, 50.3 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $29.10 an hour, 5% below the US median of $30.67. The middle half of them earn between $23.26 and $33.66 an hour. About 2,810 work in the metro. That is 37.8 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $22.07 an hour, which is 22% below the national $28.33. The middle half of them earn between $17.43 and $22.85 an hour. BLS counts 360 of them working in the area, 4.8 for every 10,000 jobs (US: 5.3), so the local bench is about average.
Roofers (47-2181), 10% of the weighting: a median of $24.39 an hour, 8% below the US median of $26.65. The middle half of them earn between $23.09 and $27.94 an hour. About 580 work in the metro. That is 7.8 per 10,000 jobs, compared with 8.7 nationally, so the supply of crews looks typical.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,000 to the midpoint estimate; the 25th percentile takes off about $2,050. That is a swing of roughly 4.0% to 5.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Raleigh-Cary has 743,120 jobs in total (BLS, May 2025), ranking 41st by size among the 300 metros on this site.

Raleigh weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Raleigh Durham Intl Ap (10 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 Raleigh are February through June and August through December: 10 of 12. Outside them, January has an average overnight low at or below freezing (32°F), and July has an average daytime high of 90°F or more.
In January the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 65 days a year with a low at or below 32°F at this station.
Raleigh gets about 46 inches of precipitation in a normal year, including roughly 5 inches of snow. The wettest months are July, August and September (5.2 inches in September). Inside the workable window, February and November are the driest, at 2.8 and 3.3 inches. The station averages about 52 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.
