How much does attic insulation installation typically cost?

Attic insulation pricing is not one-size-fits-all. A Harker technician will assess your home and provide a written estimate on site. We also help you tap available incentives, including rebates for air sealing, insulation, and ventilation up to $1,600. As an IRA-Registered Contractor, we guide you to qualifying options for Madison-area homes.

What affects cost:

• Square footage and target R-value
• Access (attic height, hatch size, obstructions)
• Existing insulation removal
• Air sealing and ventilation upgrades
• Rebate eligibility and paperwork support
