Is the price difference a dealbreaker?
That 6% gap is small — for attic insulation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

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?
R-value, air-sealing and material decide both the price and the payback. Our editors on the trade-offs.
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.
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.
Air-seal before you insulate, hit the DOE-recommended R-value for your zone, and claim every rebate you're eligible for — insulation is a rare case where doing the full job is also the cheapest one, long-term.
