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 Shreveport, LA average $39,120 a year against a U.S. mean of $54,740 — a factor of 0.715 — 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 2A. IECC R402.1.3 asks for R-30 in the attic at zone 2. 1,782 heating degree days and 2,985 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 $1,656 quote into a $2,070 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 Shreveport, LA

$1,656 is the typical number, and three bids on the same scope normally land between $872 and $2,440.

That is $244 less than the same job priced at the national average.

Why the city changes the number

About 45% of this job is labor — $745 of the $1,656 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 Shreveport average $39,120 a year, against a U.S. mean of $54,740. That is a factor of 0.715, 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 $1,656 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 $872 – $2,440, that is not automatically wrong — but it is the question worth asking out loud.
