Where the Wausau price comes from

Data note: 20% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Wausau. 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 Wausau is 0.99 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $24.03 an hour, which is 17% below the national $29.12. The middle half of them earn between $23.14 and $29.66 an hour. BLS counts 370 of them working in the area, 53.2 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 $29.82 an hour, which is 9% above the national $27.41. The middle half of them earn between $27.76 and $35.90 an hour. BLS counts 110 of them working in the area, 15.8 for every 10,000 jobs (US: 13.3), so the local bench is deeper than average.
Electricians (47-2111), 10% of the weighting: a median of $37.83 an hour, 25% above the US median of $30.38. The middle half of them earn between $24.13 and $41.57 an hour. About 480 work in the metro. That is 69.0 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 $41.71 an hour, which is 36% above the national $30.67. The middle half of them earn between $29.85 and $48.25 an hour. BLS counts 260 of them working in the area, 37.4 for every 10,000 jobs (US: 30.0), so the local bench is deeper than average.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Wausau metro, so we used the Wisconsin statewide median: $28.83 an hour against $28.33 for the US. The middle half of them earn between $23.05 and $33.42 an hour.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Wausau metro, so we used the Wisconsin statewide median: $28.54 an hour against $26.65 for the US. The middle half of them earn between $23.01 and $31.41 an hour.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($29.66 an hour) instead of the median, the labor line grows by about $3,700. At the 25th percentile ($23.14) it shrinks by about $580. The total moves by 6.6% or 1.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 69,530 jobs in the Wausau area. That makes it the 261st largest of the 300 metros we cover, with 0.04% of US employment.

When to schedule home addition in Wausau
We use NOAA's 1991-2020 climate normals for Wausau Dwtn Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
May through October is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Wausau (6 of 12 months). January, February, March, April, November and December have an average overnight low at or below freezing (32°F).
In January, February, March, April, November 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 163 days a year with a low at or below 32°F at this station.
Wausau gets about 34 inches of precipitation in a normal year, including roughly 64 inches of snow. The wettest months are June, July and August (4.7 inches in June). Inside the workable window, May and October are the driest, at 3.8 and 3.1 inches. The station averages about 5 days a year at 90°F or above.
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.
