What is behind the Bridgeport number
Labor is 70% 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 Bridgeport the blended ratio comes out at 1.13.
Materials are scaled with BEA's regional price parity for goods. Bridgeport is at 97.3 against 100 for the US, so a materials line of $18,000 nationally becomes $17,500 here (midpoint, 300 sq ft). Permits follow the all-items index of 106.9: $530 to $2,150.
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 Bridgeport. The wage table below marks each row.
What local crews earn in Bridgeport
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 Bridgeport the blend is 1.13.
Carpenters (47-2031), 50% of the weighting: a median of $30.39 an hour, 4% above the US median of $29.12. The middle half of them earn between $27.19 and $37.89 an hour. About 1,100 work in the metro. That is 27.2 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 $28.54 an hour, 4% above the US median of $27.41. The middle half of them earn between $23.23 and $36.65 an hour. About 140 work in the metro. That is 3.5 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $38.25 an hour, which is 26% above the national $30.38. The middle half of them earn between $29.16 and $49.33 an hour. BLS counts 1,630 of them working in the area, 40.3 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 $38.32 an hour, 25% above the US median of $30.67. The middle half of them earn between $29.22 and $46.99 an hour. About 1,000 work in the metro. That is 24.7 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 Bridgeport metro, so we used the Connecticut statewide median: $29.08 an hour against $28.33 for the US. The middle half of them earn between $23.00 and $37.30 an hour.
Roofers (47-2181), 10% of the weighting: a median of $39.09 an hour, 47% above the US median of $26.65. The middle half of them earn between $26.87 and $47.38 an hour. About 130 work in the metro. That is 3.2 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 $4,950 to the midpoint estimate; the 25th percentile takes off about $2,100. That is a swing of roughly 3.4% to 8.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Bridgeport-Stamford-Danbury has 404,180 jobs in total (BLS, May 2025), ranking 63rd by size among the 300 metros on this site.
