How much does spray foam insulation cost per square foot?
Spray foam pricing is calculated per square foot after we confirm foam type, thickness, and access. Open-cell and closed-cell foams are priced differently. Attic, crawl space, or rim joist locations change prep time. Removal of old insulation, air sealing, and ventilation adjustments can affect cost. Exact pricing depends on an on-site assessment. A technician will confirm scope and final price before work begins in Nashua, Manchester, and nearby areas.
