How much does spray foam insulation cost per square foot?

There isn’t a single per‑square‑foot price we can quote upfront. Spray foam cost varies by foam type (open vs. closed cell), needed thickness, accessibility (attic, crawlspace), and prep like air sealing. Our Summers technician will inspect your home, evaluate insulation and airflow, and provide a written estimate. We also address duct sealing/insulation, which can change total cost. Service available in Kokomo and Frankfort.

Quick factors that affect price:

  • Foam type and R‑value target
  • Area size and accessibility
  • Air sealing and ductwork needs
