Improve Comfort and Energy Efficiency

Insulation projects in LA run $2,500-$6,500 for attic blow-in (typical 1,500-2,500 sq ft attic), $8,000-$18,000 for whole-home wall and attic packages, and $15,000-$35,000 for closed-cell spray foam systems. Title 24 compliance is required on all permit-scope insulation work. Most projects complete in 1-3 days for attic-only retrofits; whole-home wall and attic packages run 3-7 days. Federal 25C tax credit and utility rebates layer to offset 20-40% of qualifying work.

Closed-cell spray foam delivers more R-value per inch than fiberglass batts but costs significantly more. Most California homes built before 2010 have significant air leakage at attic penetrations, can lights, and rim joists, so air sealing typically pays back faster than just adding insulation. Federal 25C credit covers 30% of qualifying insulation upgrades up to $1,200/year. Cost variance comes from material grade (fiberglass batt is cheapest, blown-in cellulose mid-tier, closed-cell spray foam premium and best for vaulted ceilings or rim joists), area covered (attic-only is cheapest; whole-home retrofit including walls is 3-5x), demo of existing material if it is contaminated or moldy ($1-$3 per square foot), air sealing as a separate line item (sealing can lights, top plates, attic hatch, ductwork penetrations is high-leverage work and runs $1,500-$4,000 standalone; doing it before insulation is the right sequence), and Title 24 + HERS verification on permitted scope (about $400-$800 added).
