What affects your insulation price
Price range
Insulation costs about $1,071 to $2,649 on average. Prep work like drywall repair or removing old insulation can add $150 to $900. Not a quote or an offer. Your price comes from the installer. Source: Angi, 2026.
What moves the number
- Where it goes. Attics take more work to get to than open walls or basements.
- Type of insulation. Blown-in and rolls cost less. Spray foam costs more but also seals air leaks.
- How much you add. Insulation is rated by R-value. A higher R-value means it blocks more heat, and it costs more.
- Removing old insulation. Wet, moldy or pest-damaged insulation has to come out first.
What to ask before you choose
- "What R-value will I end up with?" Compare this number across quotes, not just the price.
- "Will you seal air leaks first?" Sealing gaps around lights, pipes and vents makes insulation work much better.
- "Is removing old insulation included?"
- "Will you keep attic vents clear?" Blocked vents can cause moisture problems.
- "Are there rebates from my power company?" Many offer them. Ask before you book.
The catch: some older homes have attic insulation called vermiculite. It looks like small gray-brown pebbles. It can contain asbestos. If you see it, don't touch it or disturb it. Have it tested before any work starts.
