Blown-In Insulation Cost Factors 

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.

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 $1.45 to $6 depending on the type.

Area in Square FeetBlown-in Insulation Cost Range
500$725–$3,000
1,000$1,450–$6,000
1,500$2,175–$9,000

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:

Blown-In Insulation Pro Costs

The pro you hire to install your new blown-in insulation in Austin has to factor in labor costs and the amount of materials needed when giving you a quote. In general, labor accounts for 40% to 50% of the cost of blown-in insulation.

Local Labor

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.

Permits

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.

Taxes

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.

Licensing

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.

Insurance

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.

Does New Blown-In Insulation Increase Home Value?

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.
