Where the Altoona price comes from
Labor is 65% 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 Altoona the blended ratio comes out at 0.94.
Materials are scaled with BEA's regional price parity for goods. Altoona is at 100.7 against 100 for the US, so a materials line of $18,000 nationally becomes $18,100 here (midpoint, 300 sq ft). Permits follow the all-items index of 89.5: $450 to $1,800.
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 Altoona. The wage table below marks each row.
The best months for home addition in Altoona
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Altoona 3 W (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 Altoona are April through November: 8 of 12. Outside them, January, February, March and December have an average overnight low at or below freezing (32°F).
In January, February, March and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 128 days a year with a low at or below 32°F at this station.
Altoona gets about 45 inches of precipitation in a normal year, including roughly 38 inches of snow. The wettest months are May, June and September (4.4 inches in May). Inside the workable window, April and November are the driest, at 3.8 and 3.6 inches. The station averages about 6 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.

Who does the work: Altoona trade wages
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 Altoona the blend is 0.94.
Carpenters (47-2031), 50% of the weighting: a median of $27.58 an hour, 5% below the US median of $29.12. The middle half of them earn between $22.09 and $36.73 an hour. About 360 work in the metro. That is 61.4 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $25.48 an hour, 7% below the US median of $27.41. The middle half of them earn between $20.12 and $26.68 an hour. About 50 work in the metro. That is 8.5 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 $28.18 an hour, which is 7% below the national $30.38. The middle half of them earn between $22.81 and $33.00 an hour. BLS counts 170 of them working in the area, 29.0 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 $29.53 an hour, 4% below the US median of $30.67. The middle half of them earn between $23.81 and $36.41 an hour. About 80 work in the metro. That is 13.6 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 Altoona metro, so we used the Pennsylvania statewide median: $29.40 an hour against $28.33 for the US. The middle half of them earn between $23.28 and $34.01 an hour.
Roofers (47-2181), 10% of the weighting: a median of $21.35 an hour, 20% below the US median of $26.65. The middle half of them earn between $19.49 and $22.98 an hour. About 50 work in the metro. That is 8.5 per 10,000 jobs, compared with 8.7 nationally, so the supply of crews looks typical.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $6,000 to the midpoint estimate; the 25th percentile takes off about $3,600. That is a swing of roughly 6.5% to 10.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Altoona has 58,650 jobs in total (BLS, May 2025), ranking 291st by size among the 300 metros on this site.
