Blown-In Insulation Costs. Blown-in insulation is one of the most common ways to insulate the attic, crawl space, or walls of a home. The average cost is about $1,358, with most homeowners spending between $889 and $1,896, but this is dependent on whether the work is done by the homeowner or by a professional.
R-30 is the minimum recommended insulation for attics, in order to achieve more thermal efficiency. At a current price at Home Depot of about $33 per bag, the material costs will be a minimum of $495, plus 4 hours of labor. Blowing insulation into an attic is a relatively straightforward DIY attic insulation job.
