Old, wet or pest-damaged insulation has to come out first, at extra cost.

Florence labor market for attic insulation
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 Florence is 0.96 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 Florence metro, so we used the South Carolina statewide median: $22.61 an hour against $23.62 for the US. The middle half of them earn between $19.29 and $27.91 an hour.
Construction laborers (47-2061), 20% of the weighting: a median of $21.75 an hour, 4% below the US median of $22.66. The middle half of them earn between $18.11 and $26.11 an hour. About 650 work in the metro. That is 73.0 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the insulation workers, floor, ceiling and wall on your job are paid at the 75th percentile ($27.91 an hour) instead of the median, the labor line grows by about $160. At the 25th percentile ($19.29) it shrinks by about $100. The total moves by 6.7% or 4.2%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 89,060 jobs in the Florence area. That makes it the 221st largest of the 300 metros we cover, with 0.06% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $19.29 | $22.61 | $27.91 | $23.62 | 0.96 | state |
