The average cost per square foot is between $0.30 to $1.50. So, for a 500-square-foot area, your estimate will vary between $150 to $700 if you do it yourself. For a professional job, add $200 to $500 for labor, and you’re looking at around $350 to $1,000 for 6 hours of work.

To determine the amount of insulation needed, start by measuring the height and length of each of your room walls. Multiply the wall’s length by the wall’s height and don’t forget to write down the spacing of the studs so you can then determine what type of insulation will be purchased.

Can you add batt insulation overblown?

There’s no problem with installing fiberglass batts over your existing blown-in insulation. … The reason for this precaution is that the facing on the insulation batts is a vapor barrier, which is intended to prevent moisture vapor from penetrating into the insulation.
