What insulation pros earn in each metro
Roughly 55% of what you pay for attic insulation is labor, which is why local wages explain most of the price gap. The numbers below are actual metro wages for skilled installers, sourced from BLS OEWS — not guesses.

Cheapest time for attic insulation in either city
Everyone waits until fall to insulate, which is exactly why fall costs the most. Spring and summer are quieter for installers and often catch a fresh year's rebate budget before it runs dry.
How much insulation is worth paying for?
R-value, air-sealing and material decide both the price and the payback. Our editors on the trade-offs.
The rebate case
Insulation has some of the best rebate math in home improvement — utility and state programs can cover a solid share (the federal 25C credits ended Dec 2025). Check DSIRE before you book and time it to a fresh rebate budget.
The R-value case
Insulate to the DOE recommendation for your climate zone — under-insulating to save money leaves comfort and energy savings on the table that would have paid the job back.
The air-sealing case
Insulation without air-sealing underperforms. Sealing leaks first is cheap and often delivers more comfort per dollar than thicker insulation alone — make sure it's in the scope.
Of every home upgrade, insulation rewards doing it right the most: air-seal first, meet the DOE R-value for your climate zone, and use the rebates on the table. Cutting the scope here just delays the payback.
