Blown-in fiberglass attic insulation in Boca Raton typically runs $2,200–$7,800 for a standard installation. Smaller Palm Beach County homes under 1,500 sq ft run $2,200–$3,400, mid-size homes (1,500–2,500 sq ft) land around $3,400–$4,900, larger homes (2,500–4,000 sq ft) cost $4,900–$6,400, and estate-sized homes over 4,000 sq ft can reach $6,400–$7,800.
These ranges assume a standard R-49 target (16–20 inches of blown-in fiberglass), which is the Department of Energy recommendation for Florida's climate zone.
Three factors move your final Boca Raton attic insulation cost: existing attic condition (bare attics are cheapest; removal-required attics add $1–$2/sq ft), access (tight or steeply pitched attics in older Boca Raton homes may add a small premium), and R-value target (above R-49 costs proportionally more).
