How much does spray foam insulation cost per square foot?
There isn’t a one-price-fits-all cost per square foot for spray foam. The price depends on foam type (open-cell vs. closed-cell), target R-value (thickness), surface area, access (attic, crawlspace), prep and air sealing, and whether old insulation must be removed. We perform duct insulation as part of our ductwork services and can advise if spray foam or duct wraps/panels are the better fit for your Las Vegas home. A technician will price your project after an on-site inspection.
