Blown-In Insulation Cost in Phoenix [2026 Data]

The average blown-in insulation cost in Phoenix is $987. While the cost in Phoenix is around 40% below the national average, homeowners around the city might pay anywhere from $660 to $1,350. This lower overall cost is owed mostly to lower local labor costs and the fact that lower R-values are needed to keep a home insulated in Arizona. Come learn what goes into budgeting for new blown-in insulation in Phoenix.

Blown-In Insulation Cost Factors 

While lower compared to costs in cities in colder climates, blown-in insulation costs in Phoenix, AZ can still move up or down based on factors like the size of your home and the materials you select.  

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 $1.05 to $4.50 depending on the type.

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:

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 $0.20 and $2.10 per square foot for materials, not including installation. Below is a breakdown of each blown-in material type and how much it costs.

Blown-In Insulation Pro Costs

The local insulation pros you hire to add new blown-in insulation might split labor and materials evenly when creating a quote. All labor rates for this type of job take into account things like contractor insurance and business costs. Material costs include taxes.

Local Labor

Insulation installation contractors in Phoenix near you charge between $1.50 and $3 per square foot for installation alone. If you have a complicated home design, large home, or older home that requires asbestos remediation before the project can move forward, your contractor might charge closer to $3 to $4 per square foot to get this job done.

Permits

You will most likely need a permit from the City of Phoenix Planning & Development Department for new insulation. Permits are generally always necessary whenever you're performing changes like cutting open walls or part of the attic to add spray foam. All home improvement permits of this type in Phoenix start with a base permit fee of $150.

Insurance

There's no state requirement to hold general liability insurance as a contractor in Arizona. However, contractors seeking licensing from the Arizona Registrar of Contractors (ROC) must have proof of a license bond. While relaxed insurance requirements can make doing business less expensive for contractors, most still purchase general liability and workers' compensation insurance with premiums totaling $30 to $90 monthly. It's wise to only select licensed and insured pros when hiring an insulation contractor.

Taxes

Your blown-in insulation contractor will source all of the materials needed for this project. However, you'll need to budget for the extra 9% that's applied on top of ordinary costs to cover Phoenix sales tax. In Phoenix, all purchases are subject to a 5.6% Arizona sales tax, 2.8% Phoenix sales tax, and Maricopa County 0.7% sales tax.

Licensing

All Phoenix contractors working on projects valued above $1,000 are required by law to be licensed. Between exams and licensing fees, the average Phoenix contractor is paying between $800 and $1,500 to be able to legally work in the city.

Does New Blown-In Insulation Increase Home Value?

With many Valley of the Sun residents hoping to pay less than the average $268 monthly electric bill in Phoenix, upgrading insulation can significantly impact property value. While good insulation is often seen as something that's only important in cold climates, upgrading to modern, code-compliant insulation can make a home more comfortable and reduce monthly energy bills. Blown-in insulation is one of the best types of insulation for the Southwest climate because its incredible thermal resistance and air-sealing benefits create a barrier against heat in Phoenix.
