With Austin's average cost for new blow-in insulation around 5% less than the national average, the return on investment can be strong.

Blown-in insulation cost in Austin largely comes down to the size of the space you're insulating. When you hire an Austin blown-in insulation contractor, they'll spend time discussing things like R-value and the different types of insulation materials available to Austin homeowners.
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 $1.45 to $6 depending on the type.
| Area in Square Feet | Blown-in Insulation Cost Range |
|---|---|
| 500 | $725–$3,000 |
| 1,000 | $1,450–$6,000 |
| 1,500 | $2,175–$9,000 |
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-Value | Number of Bags per 1,000 sq. ft. | Description | Price Range |
|---|---|---|---|
| R-13–R-21 | 7–10 | Ideal for Austin attics | $225–$235 |
| R-30–R-49 | 15–20 | Ideal for Austin attics | $475–$1,520 |
| R-38–R-49 | 20–26 | Not common Austin | $1,235–$1,520 |
| R-49–R-60 | 26–32 | Too thick for Austin | $1,520–$1,900 |

Most Austin insulation installation contractors near you charge between $1.90 and $2 per square foot for labor alone. This takes into account things like insurance, licensing costs, and the number of workers needed to get the job done based on home size.
Adding insulation to your Austin home generally requires a permit. Any insulation combined with new electrical, plumbing, or HVAC system installations in Austin may require multiple permits to comply with all building codes. Base fees for permits start at $106.72. From there, expect your permits to total between $75 and $150.
Austin's 8.2% combined sales tax applies to any insulation materials purchased for your project. Your contractor will add this cost on top of raw material charges when billing you.
While Texas doesn't have licensing requirements for contractors, any contractor you hire to perform work on your home in Austin must be registered and licensed through the City of Austin. A contractor won't be able to obtain permits without this step. Fees associated with registering range from $115 to $300.
Contractors in Austin must show proof of insurance and bonding to obtain licensing. Overall, Austin contractors are paying $40 to $99 per month for premiums.
Any home improvement that boosts energy efficiency and lowers energy bills in Austin can increase home value—and that includes adding high-quality blown-in insulation. The Environmental Protection Agency (EPA) estimates that improving insulation and sealing can save homeowners up to 30% on heating and cooling bills per year. A recent mandate requiring air conditioning in every home in Austin is only increasing the focus on good insulation. With Austin energy rates increasing annually, having a home with energy bills that are low compared to similar properties can potentially reduce a home's time on the market.
