Over time insulation wears out, gets damaged or stops working well. That's when it's time to remove the old material and install new. Here's what drives the cost, what to expect, and how to save without cutting corners.
What affects the cost to replace insulation
Type of insulation
Spray foam costs more upfront but seals air leaks best. Fiberglass is budget-friendly but doesn't seal gaps.
Size of the area
Bigger spaces need more material and labor; a 2,000 sq ft attic costs more than a 1,000 sq ft one.
Condition of the old insulation
Wet, moldy or pest-infested insulation has to come out, which adds labor and disposal fees.
Labor and access
Labor rates vary by area, and hard-to-reach spaces like crawl spaces or cathedral ceilings take longer.
Removal plus new install: what to expect
Removal
Removal usually runs $1 to $2 per sq ft, including protective gear, safe removal and disposal. If anything hazardous like asbestos turns up, removal costs much more.
Installation
New insulation runs about $0.50 to $1.50 per sq ft for fiberglass batts, $1 to $2 for blown-in cellulose, and $1.50 to $3.50 for spray foam.
Example: a 1,000 sq ft attic
Removal
$1,000 – $2,000
New insulation
$1,000 – $3,500
Total
$2,000 – $5,500
Typical project
Most South Florida attics land in this range
Tips to save
- Get quotes from more than one local contractor.
- Pick the material that fits your budget and goals.
- Book removal and installation together to save on labor.
- Ask about utility rebates for energy-efficient upgrades.
- Clear the attic or crawl space yourself before we arrive.
Why quality insulation matters
Good insulation keeps your home cooler, lowers bills and improves comfort and air quality. Poor insulation leads to drafts, moisture problems and higher utility costs, so look for experienced pros who use quality materials and follow safety standards.
