How much is blown insulation in attic?

If you need to add insulation in your attic, save big by blowing in cellulose insulation yourself. The pros charge $1,500 to $2,000 to do a 1,200-sq.-ft. house. You can do it yourself for about $500. Blowing attic insulation isn't hard, but it's dusty, sweaty work.

Keeping this in consideration, how much does it cost to put in insulation?

Cost: The average cost per square foot is between $0.64 - $1.19. So, for a 500 square foot area, your estimate will vary between $145 to $200, if you do it yourself. For a professional job, add between $150 to $300 for labor, and you're looking at around $300 to $500 for 6 hours of work.
