Why Dallas prices look the way they do
The wage side of the estimate leans on carpenters, who do 50% of the hours on a typical job. Their local median is $23.44 an hour. Add the other trades involved and the blended wage index for Dallas is 0.84 (US = 1.00), which puts labor at 62% of the total.
Materials are scaled with BEA's regional price parity for goods. Dallas is at 102.8 against 100 for the US, so a materials line of $18,000 nationally becomes $18,500 here (midpoint, 300 sq ft). Permits follow the all-items index of 103.1: $520 to $2,050.
What local crews earn in Dallas
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 Dallas the blend is 0.84.
Carpenters (47-2031), 50% of the weighting: a median of $23.44 an hour, 20% below the US median of $29.12. The middle half of them earn between $20.98 and $27.40 an hour. About 9,480 work in the metro. That is 23.4 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 $23.45 an hour, 14% below the US median of $27.41. The middle half of them earn between $21.31 and $27.15 an hour. About 7,920 work in the metro. That is 19.6 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $28.37 an hour, which is 7% below the national $30.38. The middle half of them earn between $22.85 and $34.32 an hour. BLS counts 20,930 of them working in the area, 51.7 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 $29.45 an hour, 4% below the US median of $30.67. The middle half of them earn between $23.04 and $36.20 an hour. About 11,980 work in the metro. That is 29.6 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $23.18 an hour, which is 18% below the national $28.33. The middle half of them earn between $21.91 and $28.55 an hour. BLS counts 1,870 of them working in the area, 4.6 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 $22.59 an hour, 15% below the US median of $26.65. The middle half of them earn between $18.54 and $27.29 an hour. About 2,180 work in the metro. That is 5.4 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $2,600 to the midpoint estimate; the 25th percentile takes off about $1,600. That is a swing of roughly 3.1% to 5.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Dallas-Fort Worth-Arlington has 4,049,800 jobs in total (BLS, May 2025), ranking 4th by size among the 300 metros on this site.

Dallas 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, Dallas Love Fld (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 Dallas are October through May: 8 of 12. Outside them, June, July, August and September have an average daytime high of 90°F or more.
Dallas gets about 38 inches of precipitation in a normal year, including roughly 2 inches of snow. The wettest months are May, June and October (4.8 inches in October). Inside the workable window, January and February are the driest, at 2.6 and 2.8 inches. The station averages about 108 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.
