How much does spray foam insulation cost per square foot?

There isn’t a single per‑square‑foot price for spray foam. Costs depend on foam type (open‑ vs. closed‑cell), target R‑value (thickness), area size, access, and prep/air‑sealing needs. A Summers technician will inspect your home and provide a written estimate before work begins. We serve homes in Carmel, Noblesville, Westfield, and Fishers.

Quick checks:

• Note areas to insulate (attic, crawl, rim joist).
• Check access and existing moisture issues.
• Decide on comfort or energy‑savings goals.
