re: Blowing in insulation: how difficult? And how much would it suck in June?

Not too bad considering the attic had very little insulation

Thanks, I have R-30 but it’s settled over the years but still over the rafters and would like to bring it up to R-38/R-40. I know my ceiling drywall seams, top plates, electrical lines, pipe vents, recessed lights are not air sealed. I’ve considered doing the air sealing myself, later this fall when it cools, but I’ll likely get estimates before making any decision on this.
