How much does spray foam insulation cost per square foot?

Spray foam insulation is priced per square foot after an on-site assessment. We do not publish a single per‑sq‑ft rate for Fort Wayne–area homes. A Summers technician will measure the area and confirm the price in writing before work begins. Final cost depends on foam type and thickness.

  • Open-cell vs closed-cell foam.
  • Depth/R-value requested.
  • Attic, crawlspace, walls, or rim joists.
  • Prep, air sealing, and ventilation needs.
  • Old insulation removal and cleanup.
  • Access and square footage.
