Is the gap worth worrying about?

What insulation pros earn in each metro
Since labor accounts for around 55% of what a attic insulation job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

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 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.
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.
Hit the DOE R-value for your zone, air-seal first, and stack the rebates. Insulation is one of the few upgrades where doing it fully is also the cheapest path to payback.
