How much does spray foam insulation cost for 1500 square feet?

Spray foam insulation cost for 1,500 square feet is confirmed after an on-site assessment because price varies by foam type, target R-value, and how easy the space is to access. The biggest cost swing is choosing open-cell vs. closed-cell foam and the thickness required to meet your efficiency goals.

We install for homeowners in the Cave Creek area and size foam depth for peak summer heat rather than a one-size estimate. Utility incentives may reduce your net cost; SRP lists rebates up to $600 for insulation improvements.

To produce a firm quote, a technician will review:

• Areas being insulated (attic, walls, or both)
• Whether old insulation must be removed and disposed
• Obstructions, recessed lights, and sealing details
• Ventilation or code-related adjustments
