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 Brick, NJ average $60,330 a year against a U.S. mean of $54,740 — a factor of 1.102 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for insulation workers, floor, ceiling, and wall near Brick, NJ, so this is the New Jersey state average, SOC 47-2131.
  • This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Brick, NJ, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
  • Climate zone 3A. IECC R402.1.3 asks for R-49 in the attic at zone 3. 3,448 heating degree days and 1,509 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 $3,180 quote into a $3,975 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.

Why the city changes the number

About 45% of this job is labor — $1,431 of the $3,180 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 Brick average $60,330 a year, against a U.S. mean of $54,740. That is a factor of 1.102, 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 $3,180 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 $1,674 – $4,686, that is not automatically wrong — but it is the question worth asking out loud.
