When it comes to improving energy efficiency and lowering utility bills, blown-in insulation remains one of the most cost-effective solutions for homeowners. Whether you’re building a new property or upgrading your existing attic, blown-in insulation provides excellent thermal resistance, soundproofing, and air sealing benefits. In 2025, the cost of installation depends on several factors like the size of your home, insulation material type, labor charges, and regional pricing.
At Alabama Pole Barns LLC, we help homeowners across Alabama make smart, energy-efficient choices by offering high-quality blown-in insulation services. This guide breaks down the cost of blown-in insulation in 2025, its benefits, and the factors that influence your investment so you can make an informed decision.
What is Blown-In Insulation?
Blown-in insulation, sometimes referred to as loose-fill insulation, is a type of insulation material that is literally “blown” into wall cavities, attics, and floors using a specialized machine. Unlike traditional batt insulation, blown-in insulation fills gaps, cracks, and crevices more effectively, creating a seamless thermal barrier.
Common blown-in insulation materials include:
-
Cellulose – Eco-friendly, made from recycled paper products.
-
Fiberglass – Lightweight, affordable, and resistant to fire.
-
Mineral Wool – Durable and excellent for soundproofing.
Average Cost of Blown-In Insulation in 2025
The national average cost to install blown-in insulation installation in 2025 ranges between $1,500 and $3,500, with most homeowners paying around $2,500 for a 1,500–2,000 sq. ft. home.
Cost Per Square Foot
-
Cellulose: $0.80 – $1.50 per sq. ft.
-
Fiberglass: $0.90 – $1.60 per sq. ft.
-
Mineral Wool: $1.50 – $2.20 per sq. ft.
Total Cost by Home Size
-
1,000 sq. ft. home: $1,000 – $2,200
-

-
3,000 sq. ft. home: $3,500 – $6,500
These prices include both materials and professional installation. DIY projects may lower labor costs, but improper installation could reduce efficiency and shorten lifespan.
Factors Affecting Blown-In Insulation Costs
Several elements play a role in determining the final installation cost:
1. Type of Material Used
-
Cellulose is affordable and eco-friendly.
-
Fiberglass is widely available and low cost.
-
Mineral Wool is pricier but offers superior fire resistance.
2. Home Size and Layout
Larger homes require more insulation and labor. Complex structures with tight corners or multiple levels may increase installation time and costs.
3. Labor Costs
In Alabama, labor costs range between $50 and $100 per hour, depending on the contractor and project complexity.
4. Existing Insulation Removal
If your attic or walls already have damaged or moldy insulation, removal services may add $1 – $2 per sq. ft. to your total cost.
5. R-Value Requirements
Higher R-values (thermal resistance) require more insulation material, which increases cost but improves energy savings.
