Closed Cell Foam Prices

Just had open cell done on an entire house. Closed cell was double the price of the open cell and not as thick. Same thickness of closed cell you're looking at 3x the price of open cell. $9k for a 2100 sq ft 2 story house. Closed cell would've been $18k.

For a job as small as yours I can see why the quotes would be high. The time spent cleaning the equipment, preparing the chemicals, cleaning up the room after spraying ,etc. They aren't making much doing a smaller room. If I were you, I would seal any air leaks with canned foam and caulk and do blow-in insulation or batts.
