Spray Foam Insulation Cost in Peoria: Complete Pricing Guide

How Much Does Spray Foam Insulation Cost in Peoria, IL?

Spray foam is one of the best insulation options—but it’s not the cheapest. Here’s what you’ll pay in Peoria and why the investment pays back.

Typical Spray Foam Costs in Peoria

• Open-cell foam: $1–$1.50 per board foot (typical attic: $3,000–$8,000)
• Closed-cell foam: $2–$3 per board foot (typical attic: $6,000–$15,000+)
• Rim joist sealing: $500–$2,000 per basement
• Crawl space encapsulation: $1,500–$4,000

Average Peoria home: 1,500 sq ft attic with 6″ spray foam = $6,000–$12,000 depending on type.

Open-Cell vs. Closed-Cell: Which Do You Need?

• Open-Cell: Lower cost, softer, air-permeable, R-value ~3.5 per inch. Good for interior walls and attics with proper ventilation.
• Closed-Cell: Higher cost, rigid, moisture barrier, R-value ~6–7 per inch. Best for basements, crawl spaces, and exterior applications.

For attics in Peoria: Open-cell is usually the better value. For basements: Closed-cell is worth the extra cost.

What Affects Your Spray Foam Cost

• Square footage: Larger jobs = lower per-sq-ft cost
• Foam type: Open-cell is cheaper; closed-cell costs more
• Thickness: 4″–6″ is standard. Thicker = more cost but better R-value
• Accessibility: Hard-to-reach areas take more labor
• Framing prep: If the attic is cluttered, prep work adds cost
• Removal of old insulation: Might be needed before new foam

Comparing Spray Foam to Other Insulation

• Fiberglass Batts: $0.50–$1.00/sq ft, but air leaks reduce effectiveness
• Blown Cellulose: $0.80–$1.50/sq ft, decent air sealing, less effective than spray foam
• Spray Foam: $1.50–$3.00/sq ft, superior air sealing, highest R-value per inch

Spray foam costs more upfront but performs better and lasts longer.

Energy Savings: The ROI

Spray foam typically saves Peoria homeowners:

• Winter heating: 15–30% reduction in heating costs
• Summer cooling: 10–20% reduction in AC costs
• Payback period: 5–10 years through energy savings

Over 20 years, spray foam insulation can save $10,000–$20,000+ in energy costs.

Hidden Costs to Anticipate

• Old insulation removal: $500–$2,000 to haul out old fiberglass or cellulose
• Air sealing work: Additional $1,000–$3,000 for sealing penetrations and gaps
• Ventilation adjustments: New foam may require soffit vent evaluation (~$500–$1,500)
• Warranty & warranty extensions: Most foam comes with 10-year; extended is available
