How Much Does It Cost To Install Batt Wall Insulation?

Insulation installation costs

The total insulation installation cost is determined based on the square footage of the space, the locale, and the materials. The labor cost to install insulation is based on the size of the project. Ideally, you want your whole house to be insulated, but some areas need it more than others. 

When deciding if the cost to install insulation is right for your home, there are some factors to include in calculating the cost to insulate your walls:

The size of the space

The wall insulation cost is measured per square foot, which means the bigger the space that needs wall insulation, the greater the cost. Measure the walls, floor, or space first, so you know the precise square footage and can estimate the insulation installation cost.

Insulation type

There are many different types of insulation. Each has a specific purpose, depending on the structure and material of your house and where the insulation needs to be installed. Some insulation is sprayed on, and others are more rigid and structured. It’s usually made of some combination of batt, foam, and wood. 

Locale within your home

The cost to install insulation greatly depends on the location in your home. You’ll need to calculate the insulation installation cost of your walls, floors, attic, basement, roof, and garage. Smaller spaces or vaulted ceilings will likely increase your overall wall insulation installation costs.

Labor and equipment costs for insulation

The labor and equipment cost to install batt insulation are where the price can add up quickly. The cost of wall insulation installation is correlated with the square footage of the space and what equipment is used. Some types of insulation require special tools and equipment, especially spray foam. 

Insulation cost per square foot

The cost to install wall insulation is measured by the square footage of the space, which determines the amount of batt and roll insulation required. The wall insulation cost is estimated per square foot or by the insulation roll. 

Batt wall insulation costs between $0.80 to $2.60 per square foot of the space where it needs to be installed. The insulation cost can also be measured by the roll, which costs between $20 to $90 for a surface area between 40 to 75 square feet. The overall cost of wall insulation is usually between $1,100 to $3,900. This number ranges based on the project size and R-value of the insulation. 

Labor costs for installing insulation

The labor cost to install batt insulation ranges from $0.25 to $1.30 per square foot or an hourly rate of $40 to $80. This will depend on your region, the size of your home or space needing insulation, and the experience of the crew. It takes between four and five hours for two workers to cover 1000 square feet with insulation. 

Some types of insulation are more laborious and will cost more to install. For example, if the material needs special treatment and protective gear, such as spray foam, the overall insulation installation labor costs will increase.

DIY or hire a pro to install insulation

Once you’ve decided your home needs to be insulated, you’ll have to determine if you’re going to tackle it as a DIY project or hire a professional to install the insulation. 

Some factors to consider: 

• Your budget: You can estimate the cost for wall insulation materials using the tools above, and if you have enough in your home repair budget to hire a pro, it’ll likely pay off in the long run. 
• Your time: Make a realistic plan for when you’ll fit the DIY task into your schedule to see if it is feasible. 
• Your physical fitness: It’s hard work to pull apart walls and floors, and some types of insulation are time sensitive (such as liquid hardening into a solid).

The bottom line is that you want long-lasting results that will save you money in heating and cooling many years into the future. Hiring a professional will increase the cost to install batt insulation, but it’s well worth it to have the job done right the first time.
