Blown-in insulation in Columbia costs $1.75 to $7 per square foot in Columbus.
Columbus homeowners should budget for insulation with R-values of 38 to 60 for walls and attics.
With insulation costs in Columbus below the national average, homeowners have extra budget room to remove existing insulation if necessary.
New insulation offers a great ROI amid the city's cold, snowy winters that can drive up energy bills and make homes uncomfortable when insulation is thinning or absent.
The average blown-in insulation cost in Columbus is $1,735. While that puts Columbus right in line with the national average, homeowners around the city will pay anywhere from $1,153 to $2,355 for new blown-in insulation. Ultimately, the cost for this project will come down to things like the type of blown-in insulation selected, the R-value that's best for the section of your home being insulated, and size of the area being insulated. Learn more about the cost factors that stand out when budgeting for this project.
The city's harsh winters make this a place where higher R-values are needed. Your contractor will explain local building codes and energy-efficient recommendations when helping you choose an R-value blown-in insulation for your home.
The biggest cost factor is the size of the area that requires insulation. A larger area requires more insulation and labor, increasing the overall price. This metric is calculated by multiplying your square footage by the cost per square foot of your chosen insulation materials, which are detailed below. However, a general range for blown-in insulation per square foot is $1.75 to $7 depending on the type.
| Area in Square Feet | Blown-in Insulation Cost Range |
|---|---|
| 500 | $875–$3,500 |
| 1,000 | $1,750–$7,000 |
| 1,500 | $2,625–$10,500 |
When measuring the efficacy of any insulation material, it all boils down to the R-value. Generally speaking, higher is better, though there are two metrics to consider. There’s the overall R-value and the per-inch R-value. For example, if you want a total R-value of 30, you’ll need ten inches of insulation at an R-value of 3.0 per inch. Materials with higher R-values cost more, like sheep’s wool, but you don’t need as much material to complete the installation.
Below is a breakdown of R-values and the corresponding prices:
| R-Value | Number of Bags per 1,000 sq. ft. | Description | Price Range |
|---|---|---|---|
| R-13–R-21 | 7–10 | Not ideal for Columbus | $225–$325 |
| R-30–R-49 | 15–20 | Appropriate for Columbus walls | $480–$1,500 |
| R-38–R-49 | 20–26 | Ideal for Columbus walls | $1,250–$1,600 |
| R-49–R-60 | 26–32 | Ideal for Columbus attics | $1,600–$2,000 |

Like most contractors, Columbus blown-in insulation installers often price this project by the square foot. In addition to charging for materials, contractors also factor in labor costs that stem from actual labor hours, insurance and bonding costs, and costs of doing business as a licensed local contractor.
Expect local Columbus, Ohio, insulation contractors near you to charge between $2.20 and $3.75 per square foot for labor alone. Some contractors may add higher fees for complex installations. For example, having a narrow attic with areas that limit accessibility can cause a contractor to charge a premium to account for the extra time needed. Removal of old insulation typically costs between $0.50 and $1 per square foot.
Your blown-in insulation contractor will check with the City of Columbus Building and Zoning Services to obtain the necessary permits for new insulation in Columbus. You will likely need a permit for this project until you're repairing or updating a very small area of existing insulation. A permit for a project of this scope typically costs less than $100 in Columbus.
In Ohio, state law requires all contractors to carry general liability insurance. On average, premiums for coverage cost a contractor $33 to $99 per month. Larger companies with employees also often carry workers' compensation insurance costing between $100 and $220 per month for a small insulation company.
The Columbus sales tax rate of 8% will apply to all materials purchased for this project. Expect your contractor to build sales tax into the materials portion of your bill only.
To legally perform work in Columbus, contractors must be licensed and registered with the Columbus Department of Building and Zoning Services (BZS). A specific trade license may also be required for certain insulation projects that involve additional work, such as roofing or electrical work. License application fees begin at $300.
Cold, windy winters in Columbus make updating your insulation a wise choice for keeping the chill away. In addition to making your home more comfortable, this cost-effective home improvement can also significantly reduce your energy bills. The ROI for this project is strongest in older homes that can become drafty in the winter.
