INSULATIONHow much does attic insulation cost in DFW?
Short answer: attic insulation in Dallas–Fort Worth often costs in the low thousands of dollars for a typical blown-in top-up. Angi's Dallas data, updated in June 2026, shows typical projects of about $1,750 to $2,600 and an average of about $2,165. Larger attics, removing old insulation, air sealing and spray foam can push the cost well past that.

Attic insulation cost per square foot
Angi's June 2026 Dallas figures, including installation:
- Blown-in insulation: about $1 to $4.25 per square foot
- Spray foam: about $2 to $5.25 per square foot
- Batts: about $2 to $4.25 per square foot
- Removing old insulation: about $1 to $1.50 per square foot
Per-square-foot prices depend on how deep the insulation goes. Topping up an attic that already has a few inches costs less than starting from bare joists.
What changes the price
- Attic size and access. Bigger attics, low roof pitches and hard-to-reach areas take longer.
- How much you have now. ENERGY STAR recommends R-49 for an uninsulated attic in North Texas, or adding about R-38 if you have 3 to 4 inches. How much do you need?
- Air sealing. Sealing gaps around lights, wiring, plumbing and the attic hatch adds cost, but it's what makes insulation work. Our process
- Removal. Wet, moldy, pest-damaged or contaminated insulation should come out first.
- Material. Blown-in fiberglass and cellulose cost less than spray foam. Compare them in spray foam vs. blown-in.
