Homeowners are paying an average blown-in insulation cost in Dallas of $1,384. However, you should budget for this project to cost anywhere from $797 to $2,017. Dallas homeowners can thank warmer weather and lower labor costs for helping to make new insulation costs lower compared to similar-sized cities around the country. Come learn about all of the cost factors influencing how much you'll pay to get blown-in insulation at your Dallas home.
Blown-in insulation cost in Dallas, TX can vary a lot based on the material you select. The area being insulated and the size of your project also influence overall costs. When researching common types of insulation, you'll see options available for things like fiberglass, wet-spray cellulose, dense-pack cellulose, rockwool, and natural wool.
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 $1.48 to $6.30 depending on the type.
| Area in Square Feet | Blown-in Insulation Cost Range |
|---|---|
| 500 | $740–$3,150 |
| 1,000 | $1,480–$6,300 |
| 1,500 | $2,220–$9,450 |
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 Dallas floors and walls | $195–$280 |
| R-30–R-49 | 15–20 | Acceptable for Dallas attics | $425–$1,360 |
| R-38–R-49 | 20–26 | Ideal for Dallas attics | $1,105–$1,360 |
| R-49–R-60 | 26–32 | Good for Dallas attics–but not necessary | $1,360–$1,700 |
