How much does spray foam insulation cost per square foot?

We don’t quote a single per square foot price for spray foam; we confirm pricing after an on-site assessment. Your cost depends on foam type (open-cell or closed-cell), required thickness/R-value, any removal of old insulation, attic or crawlspace access, and air-sealing needs. A technician will measure the area and give you an upfront, job-based price. We serve homes in Rohnert Park, Novato, and Petaluma. Members of Lucky’s Comfort Club get a 10% discount on heating, cooling, and plumbing services.
