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

Did you DYI this? If so, how difficult was it to do with existing blown in insulation?
Not too bad considering the attic had very little insulation and i could see and walk on the joists. Move the insulation to the side, spray, and cover back up. Doing the perimeter may not be worth it in hindsight, had to lay a piece of ply to crawl on and even then could barely reach the exterior top plates. I had to be a bit more generous with the foam here since i could barely see what i was doing.

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.
