How much does spray foam insulation cost per square foot?

Spray foam pricing is calculated per square foot after an on-site assessment. We don’t post a flat rate because costs vary by foam type (open- vs closed-cell), target R-value, thickness, and how accessible the space is. Attics, crawl spaces, rim joists, and basements price differently due to prep and ventilation needs. In Roanoke and Cave Spring, we confirm the scope and give a firm quote before work begins. A technician will measure areas and check moisture and ventilation.
