Sebastian Spray Foam
Where homes lose the most

Attic Insulation

The attic is where Connecticut homes lose the most heat. We air-seal the attic floor, fix the thin spots, and bring the whole space up to full R-value with spray foam, blown-in, or both.

Why homeowners choose it

  • Air-seal first, then insulate, the order matters
  • Fixes ice dams, drafts, and rooms that never hold heat
  • Rebate-eligible through Energize CT on most attic projects
