What insulation pros earn in each metro
Labor is about 55% of a attic insulation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for attic insulation in either city
Fall is when everyone rushes to insulate before winter hits, making it the busiest and priciest season. Spring and summer see far less demand — and utility rebate budgets are often still full that early in the year.
How much insulation is worth paying for?
Insulation is one of the few home upgrades where spending more can genuinely pay for itself. Our editors on the choices that decide both cost and payback.
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
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 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.
Don't half-do an insulation job to save money upfront: seal the air leaks first, insulate to the DOE target for your zone, and stack the rebates. The full scope pays back faster than the partial one.

Since labor is roughly 55% of a attic insulation job, that wage gap is the biggest reason the installed prices differ.

Should I choose where to live based on attic insulation cost?
Probably not. Yes, $350 is a real gap, but it's a one-time cost you can partly offset in Chinatown with off-season timing and tighter bids. Long-term factors like energy prices and home condition matter more than this one number.
