How Much Does It Cost to Insulate a 2,000 Sq Ft House?

Factors That Affect the Cost of Insulation

1. Type of Insulation Material – Different materials come with varying costs and R-values (thermal resistance). Common options include spray foam, fiberglass, cellulose, and rigid foam.
   
   
2. Installation Method – Costs differ depending on whether insulation is installed in walls, attics, crawl spaces, or basements. Each area may require a specific method, impacting labor costs.
   
   
3. Existing Insulation – If your home has old or damaged insulation, removal and disposal may add to the overall cost.
   
   
4. Labor Costs – Hiring a professional ensures proper installation, but labor rates vary by location and project complexity.
   
   
5. Energy Efficiency Goals – Higher R-values provide better insulation but come at a higher price. The climate in Kansas City may require different insulation levels compared to other regions.

Cost Breakdown by Insulation Type

Spray Foam Insulation

• Cost : $1.50 - $5.00 per sq ft
• Total Estimated Cost : $3,000 - $10,000
• Pros : High energy efficiency, air-sealing properties
• Cons : Higher initial cost, professional installation required

Fiberglass Batt Insulation

• Cost : $0.60 - $1.20 per sq ft
• Total Estimated Cost : $1,200 - $2,400
• Pros : Affordable, widely available
• Cons : Less effective at sealing air leaks, lower R-value per inch

Blown-In Cellulose Insulation

• Cost : $0.90 - $1.50 per sq ft
• Total Estimated Cost : $1,800 - $3,000
• Pros : Eco-friendly, better at filling gaps
• Cons : Can settle over time, requires professional installation

Rigid Foam Board Insulation

• Cost : $1.50 - $3.00 per sq ft
• Total Estimated Cost : $3,000 - $6,000
• Pros : High thermal resistance, moisture-resistant
• Cons : More expensive, may require additional sealing

Additional Costs to Consider

• Insulation Removal : $1.00 - $2.00 per sq ft if replacing old insulation
• Air Sealing & Vapor Barriers : Can add $500 - $2,000 to total costs
• Energy Audits : Some homeowners invest in an energy audit before insulation installation to identify heat loss areas (typically costs $200 - $500)
