How much does spray foam insulation cost per square foot?
We price spray foam insulation per square foot after an on-site assessment. Final cost in Portland–area homes depends on access, foam type (open-cell vs closed-cell), target R-value (thickness), prep and protection, and whether old insulation needs removal. A technician will confirm square footage and provide a written quote before work.
Quick checks:
- Tell us attic, crawlspace, or walls.
- Note access points and any existing insulation.
- Ask about pairing with duct sealing (Sky Seal) for efficiency.
