Wages behind the Texas number
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 6 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.84 for Texas.
For carpenters (47-2031, weighted 50%) the local median is $23.51 an hour, which is 19% below the national $29.12. The middle half of them earn between $21.48 and $27.78 an hour. BLS counts 33,540 of them working in the state, 23.8 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $22.84 an hour, which is 17% below the national $27.41. The middle half of them earn between $19.53 and $26.73 an hour. BLS counts 26,430 of them working in the state, 18.8 for every 10,000 jobs (US: 13.3), so the local bench is deeper than average.
Electricians (47-2111), 10% of the weighting: a median of $28.16 an hour, 7% below the US median of $30.38. The middle half of them earn between $22.44 and $34.20 an hour. About 76,770 work in the state. That is 54.6 per 10,000 jobs, compared with 48.7 nationally, so the supply of crews looks typical.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $28.77 an hour, which is 6% below the national $30.67. The middle half of them earn between $22.78 and $35.63 an hour. BLS counts 44,090 of them working in the state, 31.3 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081), 10% of the weighting: a median of $22.88 an hour, 19% below the US median of $28.33. The middle half of them earn between $19.28 and $28.09 an hour. About 5,760 work in the state. That is 4.1 per 10,000 jobs, compared with 5.3 nationally, so expect fewer local crews to bid.
For roofers (47-2181, weighted 10%) the local median is $22.13 an hour, which is 17% below the national $26.65. The middle half of them earn between $18.00 and $25.78 an hour. BLS counts 5,740 of them working in the state, 4.1 for every 10,000 jobs (US: 8.7), so the local bench is thinner than average.
A crew paid at the 75th percentile for carpenters ($27.78 an hour) would add about $2,800 to the statewide midpoint; one at the 25th percentile ($21.48) would take off about $1,350. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 14,071,160 jobs across Texas (May 2025), which is 9.0% of US employment.

Texas metro-by-metro prices
6 of the 21 metros sit above the statewide midpoint of $50,900, and the top-to-bottom gap is 22%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

Weather windows across Texas
Season matters for home addition. For each Texas metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Texarkana has the longest comfortable season of the metros we cover in Texas at 10 months (September through June); Amarillo has the shortest at 6 (March through May and September through November). Rainfall runs from 9 inches a year in El Paso to 65 inches in Beaumont.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
