I've got about 800 sqft under my garage I want to spray foam. 3-4" with closed cell foam to about an r30. Reason I've decided on sprayfoam is the floor above the garage is dimensional oak. I'm hoping between the vapor barrier, added insulation and sticky foam I can quiet down some of the squeaks. Right now its only an r11 with 1/2" standard drywall and a popcorn ceiling texture. I'm going to do some plumbing, electric, and if I'm going to trash the ceiling anyhow I'd rather just re-do what shouldn't have been done before.
So question is this: I'm in the Northeast and have heard quotes of $.75-$2.00/bf for closed cell insulation. I'm getting some quotes but is sure seems like its not worth it to get a sprayfoam kit and tak a stab at it myself. Anybody have luck with the kits?
