Insulation service costs depend on your project and location. Check with a local pro for your specific job.
Blown-in insulation machine rental costs $50 to $880, with most homeowners spending around $320, plus insulation material expenses for your project.
The rental location and duration determine your final machine cost, with home improvement stores offering better daily rates than rental yards.
You should account for protective gear expenses including dust masks, eyewear, gloves, plywood boards, and work lights when creating your budget.
Hiring a local insulation company ensures your blown-in insulation project is done well and helps the property retain the maximum value.
In 2026, the national average cost to rent a blown-in insulation machine is $320. Most homeowners spend between $100 and $500, with the cost driven by rental duration, location, and whether you choose a home improvement store or a dedicated rental yard.
Blown-in insulation comes in three material types, loose-fill, cellulose, and rock wool, with prices ranging from $0.50 to $2.30 per square foot. The blower you rent must be matched to the material you plan to use, since different types of home insulation are not always interchangeable between machines.
Rental costs stay fairly consistent across blower types, but your total project cost will shift depending on which insulation material you select:
| Material | Average Cost per Square Foot in 2026 |
|---|---|
| Loose-fill fiberglass insulation | $0.50–$1.10 |
| Cellulose insulation | $0.60–$2.30 |
| Rock wool insulation | $1.40–$2.10 |
Blown-in loose-fill fiberglass is a lightweight material made from thin glass fibers, used primarily for wall and attic insulation, and installing it costs $0.50 to $1.10 per square foot, plus labor fees.
Cellulose is the most common choice for blown-in installations, made from finely shredded recycled cardboard or newspaper treated to resist mold and fire, and installing it costs $0.60 to $2.30 per square foot, plus labor fees.
Installing blown-in rock wool costs $1.40 to $2.10 per square foot, plus labor fees. Rock wool is made from an iron byproduct combined with other minerals and spun into an airy, wool-like form. It has excellent fire resistance, making it a common choice for connecting walls and floors between homes and additions.
The total cost of your insulation blowing machine rental includes not only the rental fee but potentially the insulation cost, professional labor, or the tools and equipment needed for a DIY installation. Here's how those costs break down:
Renting a blown-in insulation machine typically costs $50 to $210 per day or $300 to $880 per week, with most homeowners budgeting $100 to $200 per day on average. Home improvement stores generally offer the best daily rates, while rental yards can provide better value for weekly rentals. Some insulation manufacturers and rental stores will loan you the machine at no charge when you purchase a minimum of 20 to 30 bags of insulation.
The table below shows how costs vary by rental location and duration. The second figure shown for the home improvement store is the average price expected if you purchase the minimum number of insulation bags:
| Time Period | Rental Yard Cost in 2026 | Home Improvement Store Cost in 2026 |
|---|---|---|
| Half Day (4 hours or less) | $200 | $35–$50 / $0 |
| Full Day | $200 | $50–$100 / $0 |
| Week | $500–$880 | $350 / $300 |
| Month | $1,500 | $1,400 / $1,350 |
Blown-in insulation materials differ in thickness and thermal resistance, so the amount you need to fill a given space will vary by material type.
Costs vary by material, as the following table shows:
| Material | Average Cost per Square Foot in 2026 |
|---|---|
| Loose-fill fiberglass insulation | $0.50–$1.10 |
| Cellulose insulation | $0.60–$2.30 |
| Rock wool insulation | $1.40–$2.10 |
Hiring a local insulation contractor runs about $40 to $70 per hour for labor, and most blown-in insulation jobs wrap up in 4 to 8 hours for a total labor cost of $160 to $560. Wall insulation is more complex, often requiring at least 20 hours and a total labor cost of $800 or more. Older homes and thicker insulation installations can push hourly rates higher, and the pro you hire will typically bring their own blower, eliminating the need for a separate machine rental fee.
If attempting a DIY blown insulation installation, you'll need specific tools and equipment. Below are the items you'll need and the average cost of each if you don't already have them around your house:
| Tool / Equipment | Average Cost in 2026 |
|---|---|
| Dust masks | $20 per pack |
| Protective eyewear | $15 per pair |
| Protective gloves | $10 per pair |
| Plywood boards to balance on | $20 each |
| LED headlamp or work light | $25 each |
DIY blown-in insulation costs include $100 to $200 per day for machine rental, $0.50 to $2.30 per square foot for insulation, and at least $90 in protective gear. You’ll save $160 to $560 by DIYing, but hiring an insulation pro near you comes with major perks and even potential cost savings.
Although adding blown-in insulation can be tackled by some DIYers, there are several reasons to hire a pro:
A local insulation pro will know what type of insulation works best for your home, netting you more energy savings.
A pro can get the job, including prep and cleanup, done in just a day or two. It takes longer to DIY, which can add up to higher machine rental fees.
A pro can safely work around electrical wires, plumbing, and other objects.
Insulation pros have all of the necessary equipment, including the blown-in insulation machine and protective gear, to complete the job.
Mistakes can lead to blocked air vents, damaged plumbing or wiring, and drafts that cause your utility bills to skyrocket.
An insulation company can inspect the area and check for issues like moisture before installing insulation.
Insulation must meet local building codes, and a pro can ensure your home meets standards and avoids penalty fees.
It’s best to let a pro complete this job for the biggest energy savings, but if you want to help, you can:
Clear the area of furniture and other objects.
Remove any loose or fallen insulation.
Check for any drafts and take note of where they are to notify the pro.
Check for local and state rebates on insulation improvements, and start the application process.
According to Angi data, 54% of homeowners have blown-in insulation in their attics, making it the most popular location for this type of installation. Walls and ceilings are also common areas where homeowners choose to add blown-in insulation.
Most insulation blower machines are powered by electricity, so ensure that the machine is plugged in. Familiarize yourself with all of the machine's control buttons, including the power and kill switches. Ensure the hose is connected to the machine and place the other end of the hose pointing toward the area you want to fill with insulation.
Next, add the insulation material by dumping it into the top of the machine so it fills it about halfway. Press the “power on” button, and point the hose where you want the insulation to be blown. Ideally, you'll have a partner to help with this process, but it is doable for a solo DIYer. Continue using the hose to blow the insulation in the areas that you want to fill, and power off the machine if you need to refill it. Once you’re finished, turn the power off and unplug the machine.
When you’re renting an insulation blower, there are several things you can do to help keep your costs down:
Before picking up your blower, ensure that you have all your materials and supplies set up in your installation space to maximize your rental time.
Home improvement stores tend to offer better rates than rental yards, so shop around at different stores in your area to find the best price.
Some rental facilities will loan you the blower for free with the purchase of a certain number of bags of insulation material.
Homeowners in some states can take advantage of state tax credits when improving their home insulation. Check the U.S. Department of Energy DSIRE website to see if you qualify.
Discuss project specifics, such as the size of the area, any plumbing or piping present, and any noticeable drafts.
Ask the pro about what type of insulation works best for your home and local climate.
Schedule an inspection to check for moisture, air leaks, and other concerns that could affect the insulation installation.
If budget allows, inquire about add-ons, like radiant barriers and baffles, to further improve home efficiency.
Set a project timeline based on availability, potential issues that need to be addressed, and any add-on features.
