Here is the average cost of blown-in insulation per square foot.
Blown-in insulation is attic insulation designed to manage your home’s temperature better. It reduces heat loss by inserting tiny insulation particles into the attic voids. It can reduce your energy costs when fitted correctly.
The cost of installing blown-in insulation per square foot should be known, though. Your budget for this home renovation project will improve with this knowledge.
This article provides a thorough explanation of the typical cost of installing blown-in insulation per square foot, saving you the time of researching.
The Meaning of Blown-In Insulation
Usually composed of fiberglass, cellulose, or mineral wool, blown-in insulation is a fluffy, loose-fill insulation material. In homes and buildings, it is often utilized to insulate the floors, walls, and attics.
It is a practical method for reducing heating and cooling costs and improving energy efficiency.
It is possible to use a blower with a hose connection to blow this insulation into hard-to-reach areas. It is therefore a strong choice for retrofitting existing structures.
Cold locations with periodic severe temperatures are best suited for this form of insulation. Because it’s composed of recycled materials, it’s also environmentally beneficial.
Typical Cost of Blown-In Insulation Cost Per Square Foot
Blown-in insulation currently costs between $3.66 and $7.60 per square foot. Depending on the project’s size and material quality, the price may change.
Material prices may range from $0.50 to $2.30 per square foot. Attic spaces cost $1 per square foot, wall spaces $1.50 per square foot, and labor costs $40-$70 per hour.

Average Cost Per Type
The material used determines the standard cost of blown-in insulation. The price range for fiberglass insulation is between $0.64 and $1.10 per square foot.
This type of installation typically has an R-value of 2.5 to 3.5 per inch. Therefore, compared to some other forms of insulation, it is less effective.
In contrast, the cost of cellulose insulation ranges from $0.60 to $1.80 per square foot. A fire-retardant chemical is combined with recycled materials such as newspaper and denim to create this type of insulation.
Generally speaking, R-values fall between 3.2 and 3.7 per inch.
Another type of blown-in insulation is rock wool, made from recycled materials like basalt and slag. Compared with other forms of blown-in insulation, it is more costly. The typical cost per square foot ranges from $1.40 to $2.10.
Last but not least is Natural Wool Blown-In Insulation, an eco-friendly option made from sheep’s wool. To comply with safety regulations, wool fibers are usually treated with a fire-retardant and are mold-resistant.
This material typically costs between $1.50 and $3.10 per square foot.
Extra Charges for Installing Blown-In Insulation
It’s not enough to know how much blown-in insulation typically costs per square foot; you also need to know if there are any additional installation fees.
There are, of course. A contractor will bill you for the time it takes to clear out your attic if it is crammed with boxes, furniture, and other possessions.
Remediation of mold and asbestos is an extra cost. The typical cost of mold removal is $5,000, but the exact amount depends on the severity of the issue. Similarly, the contractor could charge extra for the inconvenience if they have to work in confined or small areas.
When working in your attic or wall cavities, you’ll also incur higher costs if there is structural damage, roof leaks, pest infestations, or other issues.
There may be additional costs if your house has significant gaps between the living area and the attic, which could allow drafts to enter. This might be several hundred bucks or over a thousand dollars.
Factors That Determine Blown-In Insulation Costs
The price of installing blown-in insulation in your house can vary based on a few things.
These variables include the space’s accessibility, the type of insulation used, and the area’s size. The cost may also be affected by geographic location.
In terms of area, a 1,000-square-foot attic will cost significantly more than one that is half that size. Second, blown-in insulation is available in various forms. Every kind has a different financial impact.
Loose-fill fiberglass insulation is the least expensive option, typically ranging from $0.40 to $1.20 per square foot. Spray foam insulation is the most costly kind of insulation, with prices as high as $3.00 per square foot.
Lastly, the cost of insulation is also significantly influenced by the building’s location. Insulation costs can differ based on local labor rates and geographic location.
You should expect to pay more for insulation installation if you live in a region with high labor costs.
Pros and Cons of Blown-In Insulation
Blown-in insulation’s ability to fill small cracks and gaps for more thorough coverage is one of its benefits. In comparison to other insulation types, this one is very cheap.
When installed correctly, blown-in insulation should reduce your energy costs and improve home comfort by retaining heat in winter and cooling air in summer.
Also, blown-in insulation resists sound and fire. It could keep bugs away, depending on the insulation. Hard-to-reach crevices and nooks in your walls and floors can be filled with blown-in insulation.
It is therefore an ideal choice for insulating your home.
But the installation procedure can be more time-consuming and messy. Because blown-in insulation requires drilling holes and then patching them, walls are particularly challenging.
If not done carefully, it could harm the walls.
Furthermore, if it is not well-maintained, it may cause your ceiling to sag. Over time, blown-in insulation will start to mold if it is exposed to moisture.
Thus, these are all potential risks associated with this type of insulation. To ensure proper installation, carefully review the procedure and consult an expert before having blown-in insulation installed.
Compared with other types of insulation, blow-in insulation costs less per square foot. This makes it a desirable choice for many homeowners.
Aiming to increase their homes’ energy efficiency. As you can see, you can still achieve the required energy efficiency without spending a lot on insulation materials.
There are a few variables, however, that can affect the cost of your installation. Therefore, be sure to account for all potential variables when creating your home renovation project budget.
