When Alaska weather lets you build
Season matters for home addition. For each Alaska metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Anchorage has 5 comfortable months (May through September), with about 23 inches of precipitation a year.
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.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Anchorage | 6 | 67 | 23 | 5: May through September |

What carpenters and the other trades earn in Alaska
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 1.31 for Alaska.
For carpenters (47-2031, weighted 50%) the local median is $35.51 an hour, which is 22% above the national $29.12. The middle half of them earn between $28.74 and $45.26 an hour. BLS counts 2,560 of them working in the state, 78.6 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $44.69 an hour, which is 63% above the national $27.41. The middle half of them earn between $44.33 and $54.34 an hour. BLS counts 240 of them working in the state, 7.4 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Electricians (47-2111), 10% of the weighting: a median of $43.00 an hour, 42% above the US median of $30.38. The middle half of them earn between $32.11 and $50.75 an hour. About 1,870 work in the state. That is 57.4 per 10,000 jobs, compared with 48.7 nationally, which suggests plenty of local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $45.15 an hour, which is 47% above the national $30.67. The middle half of them earn between $35.40 and $49.44 an hour. BLS counts 1,200 of them working in the state, 36.9 for every 10,000 jobs (US: 30.0), so the local bench is deeper than average.
Drywall and ceiling tile installers (47-2081), 10% of the weighting: a median of $35.43 an hour, 25% above the US median of $28.33. The middle half of them earn between $29.23 and $36.47 an hour. About 100 work in the state. That is 3.1 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 $32.09 an hour, which is 20% above the national $26.65. The middle half of them earn between $27.31 and $38.75 an hour. BLS counts 310 of them working in the state, 9.5 for every 10,000 jobs (US: 8.7), so the local bench is about average.
A crew paid at the 75th percentile for carpenters ($45.26 an hour) would add about $6,400 to the statewide midpoint; one at the 25th percentile ($28.74) would take off about $4,450. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 325,570 jobs across Alaska (May 2025), which is 0.2% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 50% | $28.74 | $35.51 | $45.26 | $29.12 | 1.22 | state |

Alaska metro-by-metro prices
Alaska has one metro in our dataset, Anchorage, so the statewide and metro figures are close. The state figure uses BLS statewide wages, which include rural areas. 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.
| Metro | Range (300 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Anchorage, AK | $45,800 – $92,600 | $69,200 | −2% |
