What is behind the Winchester number
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, Winchester wages are 0.86 times the national level. Labor makes up about 64% of the midpoint estimate (67% at national prices).
Materials are scaled with BEA's regional price parity for goods. Winchester is at 96.7 against 100 for the US, so a materials line of $18,000 nationally becomes $17,400 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 Winchester. The wage table below marks each row.

What local crews earn in Winchester
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 Winchester the blend is 0.86.
Carpenters (47-2031), 50% of the weighting: a median of $24.12 an hour, 17% below the US median of $29.12. The middle half of them earn between $21.03 and $29.21 an hour. About 270 work in the metro. That is 39.9 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $22.86 an hour, 17% below the US median of $27.41. The middle half of them earn between $18.55 and $26.03 an hour. About 110 work in the metro. That is 16.2 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 $28.35 an hour, which is 7% below the national $30.38. The middle half of them earn between $22.43 and $35.53 an hour. BLS counts 180 of them working in the area, 26.6 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 $27.77 an hour, 9% below the US median of $30.67. The middle half of them earn between $22.40 and $30.24 an hour. About 160 work in the metro. That is 23.6 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Winchester metro, so we used the Virginia statewide median: $26.84 an hour against $28.33 for the US. The middle half of them earn between $22.84 and $29.22 an hour.
Roofers (47-2181), 10% of the weighting: a median of $21.97 an hour, 18% below the US median of $26.65. The middle half of them earn between $18.84 and $22.64 an hour. About 40 work in the metro. That is 5.9 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 $3,350 to the midpoint estimate; the 25th percentile takes off about $2,050. That is a swing of roughly 3.9% to 6.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Winchester has 67,740 jobs in total (BLS, May 2025), ranking 267th by size among the 300 metros on this site.
