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 in New York average $66,360 a year against a U.S. mean of $54,740 — a factor of 1.212 — so the labor half is scaled by that and the material half is not.
- **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 $3,330 quote into a $4,163 invoice, so ask about each one before signing.
- **Why state matters more than people expect.** Materials ship at national prices; crews do not move. New York sits above the national mean by 21.2%, which lands on 45% of the job and moves the total by $290.
- **Use this as a bid check, not a quote.** It prices an average job in an average condition. Steep access, a second story, a tear-off of two layers, or a crew booked out three months all move the real number, and none of them are in a per-unit average.
Blowing 1600 sq ft of attic in New York
$3,330 is the typical figure, and bids on the same scope normally land between $1,753 and $4,908.
That is 1,600 ft² of attic floor at $2.08 each.
Why this is not the national number
The same job priced at the U.S. average comes to $3,040 — this one is $290 more.
The reason is one number, and it is a published one. Insulation Workers, Floor, Ceiling, and Wall in New York average $66,360 a year against a U.S. mean of $54,740, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 47-2131. That is roughly $32 an hour of trade pay, a factor of 1.212, or +21.2% against the national mean.
Labor is about 45% of this job. Material is the other 55%, and material does not care what state it is nailed down in — a pallet costs what a pallet costs. So only the labor half is scaled here, and the material half is left at national pricing.
That is the whole model, and it is deliberately simple enough to check: $1,499 of labor, $1,832 of material.
This is the trade where state matters least
Labor is 45% of a blow, the lowest of any job on these sites — the machine does the work and the bags cost what they cost. So the spread between the cheapest and dearest states is real but modest, and anyone quoting you double the figure above is not doing it because of local wages.
What is in this price
Blown fiberglass or cellulose to roughly R-49, baffles at the eaves so the soffit vents stay open, and labor.
What is not
Air sealing. Blowing insulation over unsealed top plates, wire penetrations and a leaking attic hatch buries the problem instead of fixing it, and it is the single most common way this money gets wasted. Sealing first costs a few hundred dollars and changes what the insulation is able to do.
Removal of existing insulation is separate, and so is knob-and-tube remediation if the house has it.
Depth is the thing to verify
R-49 in loose-fill is a depth, and the bag prints how many square feet it covers at each depth. Ask for the bag count and the target depth in writing, then check the depth markers after the crew leaves. Under-blowing is invisible from the hatch and is the most common shortfall in this trade.
How to use this against a real bid
Three quotes on identical scope should cluster. One well under $1,753 usually means something was left out of the scope rather than found cheaper — read what is excluded before reading the total. One well over $4,908 is either a harder job than average or a crew that does not want the work and priced accordingly.
The number above prices an average job in average condition. Access, story height, season, and how booked the crew is all move it, and none of those live in a per-unit average.
