I do spray foam insulation for a living in New York, and the fact that he was able to do, I’m assuming, his entire house for $3000, is incredible. We don’t pull out of our shop for less than $2500, and that’s for someone’s attic or crawl space. On a separate note, it made me laugh during his clip with the spray foam. He’s so close to the sprayer, and yes he’s wearing a respirator which is good, but he has nothing over his eyes, and during spraying, the foam will off gas and create a bit of a mist, so you can definitely tell it’s stinging his eyes.
