Insulation is one of the best investments homeowners can make to keep their home comfortable and energy efficient. However, it isn’t always a DIY project.
The cost of insulation varies by material, location, and size. Here is a breakdown of how much it typically costs to insulate an average home:
Cost of Materials
The cost of materials used to create insulation plays a big role in overall costs. The type of material you choose, the R-value, and the area being insulated determines the final price tag. Spray foam is generally the most expensive, followed by fiberglass batts and rolls, cellulose, and mineral wool.
The R-value of an insulation product measures how well it resists heat conduction. The higher the R-value, the more effective it is. However, the higher the R-value, the more it will cost.
Different parts of the home require different types and thicknesses of insulation. Wall cavities, for example, need a thinner layer of insulation than floors or attics. Additionally, some areas need moisture barriers, which require closed-cell spray foam.
When choosing the type of insulation to install, consider your local climate and the type of home you live in. Then, decide if you want to DIY or hire an insulation contractor. If you plan on hiring a professional, remember that spray foam and rigid foam board insulation typically require professional installation because they expand quickly and can damage structures.
Also, keep in mind that old or damaged insulation needs to be replaced immediately because it loses its R-value over time and may contain dangerous contaminants. For example, if your attic has old, clumped, or moldy insulation, it will need to be removed and replaced with new insulation.
Cost of Installation
Insulation warms your home in the winter and cools it in the summer by slowing heat transfer through walls, floors, and ceilings. It also reduces noise and moisture from the outside and indoors. The ROI for insulation is high, and it’s one of the best investments homeowners can make to improve their homes’ energy efficiency.
The cost of installation depends on several factors, including the type of insulation, where it’s being installed, and how much you need. Fiberglass batt and roll insulation is usually the most affordable, while cellulose, mineral wool, and natural fibers are more expensive.
You’ll also pay more if you choose spray foam insulation, which is best for insulating interior walls in new construction and existing homes that are drywalled. Spray foam has a higher R-value and comes in different options, including open- and closed-cell.
If you’re insulating a floor, the type of flooring will also influence the cost. Fiberglass, foam boards, and blown-in insulation work well on concrete or wood floors. For floor insulation, you can also use cork or sheep’s wool, which are more expensive but offer a healthier option.
The average cost to insulate a floor ranges from $0.30 to $1.50 per square foot, depending on the material used. This is more than for attics and garage ceilings, which are typically insulated with fiberglass.
Cost of Labor
The cost of labor used to create insulation depends on the type you choose and the size of the area you’re insulating. Some types of insulation, like spray foam, require specialized equipment and require trained professionals to install them. These experts may charge an extra fee for removing old insulation and for providing proper disposal services.
Homeowners can save money by doing some or all of their own insulating projects. However, most insulation projects are messy and uncomfortable to perform without the help of an experienced contractor. Plus, it’s not easy to figure out exactly how much insulation you need to keep your home comfortable and energy-efficient.
Adding new insulation requires determining the optimal R-value and then choosing the appropriate material and size for each space. Ideally, homeowners should consult an expert to avoid overspending or underspending and to ensure they get the best possible results.
Some of the most expensive types of insulation are blown-in, while blanket batts and rolls are cheaper. The location of the area you’re insulating also impacts the price, with attics typically costing more per square foot than garages and walls. You’ll also have to consider the type of insulation you need and if you need to remove existing insulation before installing a new layer.

Cost of Removal
Insulating a home can be an expensive undertaking, but the investment will pay off with energy savings and a more comfortable home. It’s a good idea to consult a professional contractor before you start any insulation upgrades. They can offer a free in-home energy audit and provide you with a detailed cost estimate. They will also ensure that you have the proper R-value for your climate and recommend the best insulation material for your budget.
The price of insulation is influenced by the type of material and how it’s installed. For example, spray foam requires specialized tools to install properly and will likely cost more than fiberglass batt or cellulose roll insulation. The amount of existing insulation also has a significant impact on the price. If your attic is insulated with blown-in insulation, it may require additional equipment to remove it, which can add an extra $1,000 to the overall cost.
Another factor that can significantly increase the price of insulation is whether it needs to be removed and replaced due to mold or other contamination. This is a serious health issue that can affect your family’s health and requires special cleanup. It’s important to have any old insulation that is contaminated removed by professionals who use biohazard suits to avoid exposure to potentially harmful microorganisms. This will typically add another $1 per square foot to the overall project costs.
