The short answer
Most attic blow-in jobs we completed in 2026 cost between $1,500 and $3,700, and a typical job was about $2,300. That’s for blowing Knauf fiberglass to about 13 inches (R-38) across the whole attic, with cleanup and depth rulers included. Small attics and simple top-offs land at the low end; large or hard-to-reach attics land at the high end.

What changes the price
- Attic size. More square feet means more material and more time.
- What’s already there. Topping off 6 inches costs less than starting from 2.
- Target depth. R-38 (about 13 in.) meets code for new homes here; R-49 takes more material.
- Access and prep. Low roof pitch, several attic sections, baffles, dams around flues and plumbing, or pest-damaged ducts that must be fixed first.
- Old insulation. Wet, moldy or rodent-soiled insulation should come out first, which adds a removal day.
- Distance. Jobs far outside the Waco–Temple area may include a small trip charge, shown on your quote.
Ways to save
- Ask about our cash discount.
- We offer a military discount. Thank you for your service.
- Pair jobs: vents, dams or a chimney sweep cost less on the same visit as your insulation.
Is it worth it?
For most Central Texas homes, yes. A hot attic pushes heat into your rooms all summer, and topping it off lets your A/C run less. Our customers say it best: “it really made a big difference in the electricity bill” (Steven H., Copperas Cove) and “My electric bill is already lower!!” (Andrew H.). See how much you could save.
