Due to the overwhelming response to the post, “how much does insulation cost“, I decided to write another post that is going to address the question of “how to estimate home insulation cost”. This post is going to be somewhat similar to “how much does insulation cost” article, so I am going to be brief here. Before I go deeper into the cost estimation, I want to stress that you can use this formula or method to estimate the insulation cost no matter where you live.

The question of how to estimate home insulation cost actually depends largely on if you were doing the home insulation work all by yourself or if you were going to hire some contractors to do it. Whether you are do-it-yourself or hire a contractor, the formula to estimate the home insulation cost is going to be the same and real simple. The only difference is just on the labor part. If a contractor is going to do the dirty work for you, then all you have to do is include the labor cost plus the material cost. If you decided to go adventurous, then the only cost you incur is the insulation material cost.

To estimate the insulation material cost, all you need to do is figure out what the R-value is in the first place. Of course before doing that, you need to know which area in your house that you like to install the insulation as different areas require different R-value. Other than that, you also need to know which insulation material you want to use for the specific area. Different material carries different cost. So after choosing the insulation material and figuring out the R-value, the next thing to do is measure the size of the area that you want to insulate. You need to know the size as the number determines the amount of insulation material that you are going to use.

Other than figuring out the size of the area, knowing the thickness of the insulation material is equally important as most insulation material comes in a standard thickness. You might need to stack the insulation on top of each other to achieve the desire R-value. For example, popular insulation materials such as fiberglass and cellulose batts or rolls have R-value of 3 and 3.3 per inch respectively. Therefore, to achieve an R-value of 18, you would need about 6 inches thick of fiberglass or 5.5 inches thick of cellulose. With that being said, if your fiberglass batts is 3 inches thick, then you need to stack two batts to achieve a R-value of 18.

Once you have figure out the size and also the amount of insulation material, you can call the local home depot to ask about the cost of a square feet of insulation material. By then, you will know what the total home insulation cost is. To save yourself from doing the work, you can hire a contractor to do it for you. Then you will have to add that extra labor cost into your budget.
