For a 2,000 sq ft Florida home, the attic is the highest-return efficiency upgrade — bigger than windows, and far cheaper.
Estimates are for planning only and based on typical Central Florida homes and 2026 pricing for blown-in fiberglass. Your exact price depends on attic access, existing insulation condition, and whether removal is needed — confirmed free during your inspection.
When Florida homeowners plan energy upgrades, the attic is almost always the highest-return place to start — bigger impact than new windows, and far cheaper. This calculator sizes that opportunity for your home.
It estimates your yearly savings, project cost, and payback for bringing the attic to R-38, so you can prioritize where your upgrade dollars go first.
