Attic Insulation Cost in DFW
What insulation and energy upgrades really cost — and save — in North Texas.
Attic insulation in Dallas–Fort Worth typically costs about $1,500–$5,000 for a blown-in top-up to modern R-values, depending on home size and existing insulation. A radiant barrier usually adds $1,000–$2,500, and spray foam costs more but seals and insulates in one step. These upgrades are among the best-payback improvements in our cooling-dominated climate.
