Minnesota Insulation Contractor Package

The average cost to install loose-fill (blown-in) insulation or batt insulation in a 1,200 sq. ft. attic ranges from $1,700-$2,000.

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 the insulation will be purchased.

Are you a licensed installer? Can I speak with your references? What warranty or guarantee do you provide for your insulation? What personal protective equipment do you require for your workers? Do you carry liability insurance and workers comp insurance? What type of insulation products do you offer?

Generally, insulators charge about $50 to $80 per hour. To help you calculate the cost of insulation, consider the size of the installation, the shape of the ceiling and additional services incurred. For accurate pricing, have a professional insulation installer take measurements and provide cost estimates.

R-Value is a measure of insulation's ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.

A rough estimate for hiring someone to blow insulation into a flat roof, cathedral ceiling or wall cavities is $2-$3.50 a square foot, or $1,000-$3,500 for filling 1,000 square feet of empty wall or roof space.

The cost to insulate an attic with blown-in insulation runs from $600 to $1,200, assuming it is 1,000 square feet in size. If you choose to hire a professional, expect to pay from $40 to $70 an hour for labor in addition to the cost of materials.

For example, if the square footage of the room you're planning on insulating is 1,000 square feet and you want to achieve an R-value of 60, you will need approximately 17 bags to fully insulate your room.

Cellulose blow-in insulation is constructed out of recycled paper. To determine how much cellulose insulation you need, take the square footage of the space and divide it by either the depth or the desired R-value.
