Notes
- Where the number comes from. The national price for blown-in attic insulation is $1.90 per ft² of attic floor — blown-in insulation pricing published for 2026, $1.00–$2.80 per ft². Labor is about 45% of that. Insulation Workers, Floor, Ceiling, and Wall near Scottsdale, AZ average $46,980 a year against a U.S. mean of $54,740 — a factor of 0.858 — so the labor half is scaled by that and the material half is not.

- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- Climate zone 1B. IECC R402.1.3 asks for R-30 in the attic at zone 1. 775 heating degree days and 5,080 cooling degree days is what that zone is standing in for.
- What is in the price: blown fiberglass or cellulose to about R-49, baffles at the eaves, and labor.
- What is not: removing existing insulation, air sealing before the blow, and any knob-and-tube remediation. These are the lines that turn a $1,779 quote into a $2,223 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.
blown-in attic insulation in Scottsdale, AZ
$1,779 is the typical number, and three bids on the same scope normally land between $936 and $2,621.
That is $121 less than the same job priced at the national average.
Why the city changes the number
About 45% of this job is labor — $800 of the $1,779 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.
Insulation Workers, Floor, Ceiling, and Wall near Scottsdale average $46,980 a year, against a U.S. mean of $54,740. That is a factor of 0.858, so the labor half is scaled by it and the material half is not.

The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $1,779 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $936 – $2,621, that is not automatically wrong — but it is the question worth asking out loud.
