What insulation pros earn in each metro
About 55% of a attic insulation bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.

Cheapest time for attic insulation in either city
Everyone insulates in fall before winter, so that's the busy, full-price season. Booking in spring or summer catches off-peak pricing — and utility rebate budgets are often freshest early in the year.
How much insulation is worth paying for?
How much you spend on insulation and how fast it pays back come down to R-value, air-sealing and material. Our editors break down the trade-offs.
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 rebate case
Few home projects come with rebate support like insulation does — utility and state programs routinely offset a meaningful slice of the bill (the federal 25C credit closed in December 2025). Run your address through DSIRE first, and book when a program's yearly budget has just refilled.
The air-sealing case
Blown-in or batt, insulation can only slow the heat that isn't already escaping through gaps and penetrations. Sealing those leaks costs little and frequently buys more comfort per dollar than piling on extra R-value, so confirm it's written into 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.
