Insulation Removal Costs

The cost of insulation removal typically ranges from $2.50 to $5 per square foot. Several factors influence this price, including the depth of the insulation and the accessibility of the attic area. Here’s a breakdown:

  • Depth of Insulation: Thicker insulation layers take more time and effort to remove, increasing the cost.
  • Accessibility: If your attic is difficult to access or has limited space to maneuver, the removal process becomes more challenging and time-consuming, leading to higher costs.

Sanitation Costs

After insulation removal, it’s crucial to sanitize the exposed area, especially if there have been rodents, squirrels, or other wildlife in the attic. Sanitation helps eliminate any harmful bacteria and odors left behind. This additional service typically costs between $500 and $1,000, depending on whether the area needs to be fogged or sprayed down.

New Insulation Installation Costs

Installing new insulation in your attic is a significant investment in your home’s energy efficiency. The cost of new insulation can vary widely based on the type and depth of insulation you choose:

  • Cost Range: $1.50 to $5 per square foot.
  • Insulation Type: Different materials, such as fiberglass, cellulose, or spray foam, come with varying price points and performance characteristics.
  • Depth of Insulation: Similar to removal, thicker insulation layers will cost more due to the increased materials and labor required.

Additional Factors to Consider


If your attic has been home to pests, it’s wise to invest in pest-proofing measures to prevent future infestations. This involves sealing potential entry points to keep out rodents, birds, and other wildlife. The cost for pest-proofing can vary based on the extent of the work needed.

Ventilation Baffles

Proper ventilation is crucial for maintaining a healthy attic environment. If your attic lacks ventilation baffles, installing them might be necessary. These devices ensure that your attic has proper airflow, preventing moisture buildup and helping to regulate temperatures. If baffles are already in place, this could save you additional costs.

Chris T.

My shop has had an infestation of rats for over 9 years! I tried traps and occasionally caught a rat but always they came back. On their first visit we discovered two entry points for the rats and plugged them up. After a few rats caught, my shop has returned to normalcy. Thank you Pest Patrol.
