Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Clarksville is 0.97 times the national level.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Clarksville metro, so we used the Tennessee statewide median: $23.28 an hour against $23.62 for the US. The middle half of them earn between $18.94 and $27.43 an hour.
Construction laborers (47-2061), 20% of the weighting: a median of $20.17 an hour, 11% below the US median of $22.66. The middle half of them earn between $17.68 and $23.18 an hour.

Quotes come from real crews, not medians.
