Blown-In Insulation Cost Factors 

Blown-in insulation costs in Atlanta vary depending on the size of your home and the type of insulation used, as well as the R-value. We’ll break down various Atlanta R-value guidelines below.

Size of the Area

The biggest cost factor is the size of the area that requires insulation. A larger area requires more insulation and labor, increasing the overall price. This metric is calculated by multiplying your square footage by the cost per square foot of your chosen insulation materials, which are detailed below. However, a general range for blown-in insulation per square foot is $1.70 to $7.20 depending on the type.

Area in Square FeetBlown-in Insulation Cost Range
500$850–$3,600
1,000$1,700–$7,200
1,500$2,550–$10,800

R-Value

When measuring the efficacy of any insulation material, it all boils down to the R-value. Generally speaking, higher is better, though there are two metrics to consider. There’s the overall R-value and the per-inch R-value. For example, if you want a total R-value of 30, you’ll need ten inches of insulation at an R-value of 3.0 per inch. Materials with higher R-values cost more, like sheep’s wool, but you don’t need as much material to complete the installation.

Below is a breakdown of R-values and the corresponding prices:

R-ValueNumber of Bags per 1,000 sq. ft.DescriptionPrice Range
R-13–R-217–10This is the ideal R-value for exterior walls in Atlanta; for floors, look for R-19 to R-25.$220–$315
R-30–R-4915–20This is the ideal R-value for attics in Atlanta (R-38 to R-60).$480–$1,535
R-38–R-4920–26This is the ideal R-value for attics in Atlanta (R-38 to R-60).$1,250–$1,535
R-49–R-6026–32This is the ideal R-value for attics in Atlanta (R-38 to R-60).$1,535–$1,920

Type of Insulation

The cost to install blown-in insulation depends on the type of insulation you choose for the project. Anticipate spending anywhere between $0.50 and $2.20 per square foot for materials, not including installation. Below is a breakdown of each blown-in material type and how much it costs.

Type of Blown-In InsulationR-Value per InchAverage Cost per Square Foot
Fiberglass2.5 to 3.5$0.50 to $1.05
Wet-spray cellulose3.2 to 3.7$0.60 to $1.75
Dense-pack cellulose3.2 to 3.7$1.90 to $2.20

Blown-In Insulation Pro Costs

A large portion of the overall cost to install blown-in insulation in Atlanta is the labor itself. But costs go beyond the hourly rate of the Atlanta insulation company you choose. Here are some other labor-related costs to consider.

Permits

As long as the blown-in insulation project comes in under $10,000, you shouldn’t need to budget for a permit in Atlanta. Your contractor should be able to advise on the specifics of your project, though, and any related permit costs.

Taxes

You’ll have to pay state and local sales tax on materials; if your contractor purchases these on your behalf, expect those costs to be passed on to you. In Atlanta, Georgia, installation labor is not subject to sales tax, however.

Does New Blown-In Insulation Increase Home Value?

Blown-in insulation can absolutely increase your home’s value in Atlanta. Being able to show lower-than-average cooling costs for your home to potential buyers is a tremendous value-add and might motivate them to make an offer on your home versus a similar home with higher heating and cooling costs.

Speaking of, blown-in insulation isn’t only a value-add when selling your home. You’ll also earn some of the investment back each month through reduced energy costs. On average, expect to save 15% on energy bills with insulation.

The average monthly electric bill in Atlanta is $265. Assuming you have AC in the summer and electric heat in the winter (gas heat savings will vary), you can expect monthly savings of roughly $40, or $480 a year, thanks to your blown-in insulation.
