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 Janesville. 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. 4 trades carry the job here, and each is compared with its US median. The weighted result for Janesville is 1.19 times the national level.
Construction laborers (47-2061), 40% of the weighting: a median of $26.77 an hour, 18% above the US median of $22.66. The middle half of them earn between $22.00 and $36.28 an hour. About 480 work in the metro. That is 68.7 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
For operating engineers and other construction equipment operators (47-2073, weighted 30%) the local median is $31.88 an hour, which is 11% above the national $28.78. The middle half of them earn between $27.94 and $44.34 an hour. BLS counts 240 of them working in the area, 34.3 for every 10,000 jobs (US: 30.7), so the local bench is about average.
Brickmasons and blockmasons (47-2021) carry 20% of the labor weighting. BLS does not publish this trade for the Janesville metro, so we used the Wisconsin statewide median: $38.52 an hour against $29.87 for the US. The middle half of them earn between $29.59 and $46.62 an hour.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $38.01 an hour, which is 24% above the national $30.67. The middle half of them earn between $28.72 and $49.75 an hour. BLS counts 140 of them working in the area, 20.0 for every 10,000 jobs (US: 30.0), so the local bench is thinner than average.
Quotes come from real crews, not medians. If the construction laborers on your job are paid at the 75th percentile ($36.28 an hour) instead of the median, the labor line grows by about $6,500. At the 25th percentile ($22.00) it shrinks by about $3,250. The total moves by 8.2% or 4.1%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 69,870 jobs in the Janesville-Beloit area. That makes it the 260th largest of the 300 metros we cover, with 0.04% of US employment.

When to schedule inground pool in Janesville
We use NOAA's 1991-2020 climate normals for Afton - Janesville Wwtp (5 miles from the city center). These are 30-year monthly averages, not forecasts.
May through September is the stretch where pouring concrete runs into the fewest weather problems in Janesville (5 of 12 months). January, February, March, April, October, November and December have an average overnight low of 40°F or below.
The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.
Janesville gets about 37 inches of precipitation in a normal year, including roughly 37 inches of snow. The wettest months are June, July and August (5.0 inches in June). Inside the workable window, May and September are the driest, at 4.1 and 3.7 inches. The station averages about 13 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.
