Where the Alexandria price comes from
Labor is 63% of the midpoint bill here, against 67% nationally. The mix of trades behind this job is carpenters (50%), cement masons and concrete finishers (10%), electricians (10%), plumbers, pipefitters and steamfitters (10%), drywall and ceiling tile installers (10%), roofers (10%). We weight each trade's local median wage by that share and compare it with the national median. In Alexandria the blended ratio comes out at 0.81.
On the materials line, the BEA goods price index for the Alexandria metro is 93.7 (US = 100). The midpoint materials bill for 300 sq ft comes to $16,900, compared with $18,000 at national prices. Permit and inspection fees are scaled by the broader index (85.7) and land at $430 to $1,700.
Data note: 30% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Alexandria. The wage table below marks each row.
Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 6 trades carry the job here, and each is compared with its US median. The weighted result for Alexandria is 0.81 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $22.48 an hour, which is 23% below the national $29.12. The middle half of them earn between $18.58 and $26.89 an hour. BLS counts 180 of them working in the area, 30.0 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Cement masons and concrete finishers (47-2051) carry 10% of the labor weighting. BLS does not publish this trade for the Alexandria metro, so we used the Louisiana statewide median: $23.64 an hour against $27.41 for the US. The middle half of them earn between $19.54 and $30.00 an hour.
Electricians (47-2111), 10% of the weighting: a median of $24.14 an hour, 21% below the US median of $30.38. The middle half of them earn between $21.47 and $29.80 an hour. About 170 work in the metro. That is 28.3 per 10,000 jobs, compared with 48.7 nationally, so expect fewer local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $27.63 an hour, which is 10% below the national $30.67. The middle half of them earn between $22.42 and $30.64 an hour. BLS counts 160 of them working in the area, 26.7 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Alexandria metro, so we used the Louisiana statewide median: $22.80 an hour against $28.33 for the US. The middle half of them earn between $16.01 and $29.20 an hour.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Alexandria metro, so we used the Louisiana statewide median: $23.44 an hour against $26.65 for the US. The middle half of them earn between $18.74 and $27.02 an hour.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($26.89 an hour) instead of the median, the labor line grows by about $2,900. At the 25th percentile ($18.58) it shrinks by about $2,550. The total moves by 5.9% or 5.2%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 60,000 jobs in the Alexandria area. That makes it the 288th largest of the 300 metros we cover, with 0.04% of US employment.

Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.
