For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

Insulation Type: Prices per square foot vary significantly by material.
Reflective: $0.50–$1.50
Blown-in: $1–$4
Batt: $2–$4
Loose-fill: $2–$5
Spray foam: $2–$5
Structural insulated panels (SIPs): $4–$7
Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.
Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.
