Insulating your home is a smart investment, as it helps save energy and reduces your heating and cooling costs. Among the various insulation options available, blown-in insulation is gaining popularity due to its cost-effectiveness and efficiency.
We’ve helped thousands of homeowners improve their homes with better insulation, including blown-in wall insulation and blown-in attic insulation. But the first thing everyone wants to know is: how much does it cost to install blown-in wall insulation? Let’s explore.
Reasons Why Blown-In Wall Installation Is Worth It
Blown-in wall insulation offers several benefits that make it worth considering:
- Energy Efficiency: Blown-in insulation fills all the nooks and crannies in your walls, preventing air leaks and keeping your home warm in winters and cool in summers. This leads to significant energy savings and reduces your utility bills.
- Soundproofing: Blown-in insulation acts as a sound barrier, reducing the noise from outside and between rooms. This is especially beneficial if you live near a busy road or have noisy neighbors.
- Environmental Impact: Blown-in insulation is made from recycled materials and reduces your carbon footprint. It also helps improve indoor air quality by preventing air leaks and reducing moisture.
What Is The Average Cost of Blown-In Wall Insulation?
The cost of blown-in wall insulation can vary depending on a number of factors, including the size of your home, the type of insulation used, and the installation method.
On average, homeowners can expect to pay between $1.50 and $3.50 per square foot for blown-in wall insulation. This means that a typical a 1,500 square foot home, the cost would be around $2,250 to $4,500, while a 2,500 square foot home can cost between $3,750 and $8,750 to insulate.
However, this is the materials cost and doesn’t necessarily factor in labor or other circumstances. Always contact a company for an exact quote based on your home’s unique considerations.
Blown-in wall insulation typically comes with a higher price tag compared to attic insulation. Due to the complexity of this type of work, it is crucial to seek the help of a professional insulation contractor to ensure a successful installation.

Factors That Influence the Cost of Blown-In Insulation for Walls
There are several factors that can influence the cost of blown-in insulation for walls. These include:
- The size of your home: Larger homes will require more insulation, which will increase the overall cost of the installation.
- Type of Insulation: Blown-in insulation is available in different materials such as cellulose, fiberglass, and mineral wool. The cost of each material varies, with cellulose being the most affordable and fiberglass being the most expensive.
- Wall Thickness: The thicker your walls, the more insulation material will be required, leading to higher costs.
- Accessibility: If your walls are difficult to access, the installation process may take longer, and the labor cost will increase.
- Additional Prep Work: If your walls have existing insulation, it needs to be removed before installing blown-in insulation. This adds to the overall cost.
DIY vs. Professional – Cost of Blown-In Insulation Installation
While blown-in insulation may seem like a DIY project, it’s always best to leave it to the professionals. Not only do they have the necessary equipment and expertise, but they can also ensure that the insulation is installed correctly, maximizing its effectiveness.
DIY blown-in insulation can cost around $0.50 to $1 per square foot, excluding the cost of equipment rental. However, if you make a mistake during the installation process, it can lead to higher costs in the long run. Hiring a professional, on the other hand, may cost more upfront, but it guarantees a proper installation and ensures that the insulation lasts longer.
