The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:
Size of the area
Type and R-value of the insulation
Whether your space is finished or unfinished
Accessibility of the area
Your geographical location
Amount of site preparation, especially for blown-in insulation
Whether or not you need old insulation removed
It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.
Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.
The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.
In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Why hire an insulation contractor?
While insulation may be done as a DIY project, hiring a professional is always a better choice. They have the experience and expertise to inspect your home and analyze areas where insulation is most needed.
Insulation contractors will also check the home for any existing air leaks so they can seal them prior to adding an insulation barrier. In addition, they offer critical advice regarding the best insulation material to use for your home.
How much will insulation installers near me charge?
Most homeowners spend between $3,500 to $4,500 to insulate their entire home.
This cost is often lower if only specific areas need insulation (such as the roof or the basement). Some common areas of the home requiring insulation include:
- The attic ($1,700-$2,000 for a 1,200 square foot attic)
- Exterior walls ($3,000-$7,000)
- Cathedral-type ceilings ($360- $720)
- Basement ($1,200-$1,800)
What factors should I consider? What about labor?
Cost will depend on the amount of labor required during installation. Labor costs often lie between $0.95 to $2 per square foot. In addition, the materials required for insulation may also add to your final cost. There are several methods through which insulation can be done.
- Spray foam: this involves insulation foam being applied directly to surfaces of interest using a spray gun.
- Foam board: consists of caulking and furring stripes being applied on walls using an adhesive.
- Loose fill insulation: this method uses a machine that applies fiberglass, cellulose, and mineral insulating materials on surfaces of interest.
- Blankets: involves using batt and rolls to place and staple the insulating material on specific surfaces.
Insulation contractors will play an important role in advising on which type of insulation to use. Make sure you work with a licensed and experienced professional who provides transparent pricing.
