How much does spray foam insulation cost per square foot?

Spray foam insulation is priced per square foot after an on-site assessment. Final cost depends on area size, target R-value, access and prep needs, and whether it’s added to another HVAC installation. Savings are available: SRP insulation rebates up to $600 (apply through SRP and verify eligible measures). An in-house offer provides up to $250 for qualifying insulation. You can also get 20% off normal insulation pricing when added to an installation. Service available in Phoenix and surrounding areas.
