For construction professionals, accurately estimating the cost of insulation in crawl spaces is crucial. The cost typically ranges from $2.00 to $7.00 per square foot, depending on the insulation type and project specifics. CountBricks offers real-time material pricing and labor rates to ensure precise estimates.
• Square footage of the crawl space
• Condition of joists, subfloor, and vapor barrier
• Insulation type: fiberglass batts, closed-cell spray foam, rigid foam boards, or mineral wool
• Local labor rates and space accessibility
• Required air sealing, moisture mitigation, and code upgrades
• Disposal fees for old insulation or debris
Each factor affects material quantity and labor hours. A straightforward crawl space might require minimal time, while complex areas may need specialized solutions, impacting the overall cost.
• Fiberglass batts: $2.00 – $3.50 per square foot installed
• Rigid foam boards: $3.50 – $5.50 per square foot installed
• Closed-cell spray foam: $4.50 – $7.00 per square foot installed
These figures include labor, fasteners, and clean-up but exclude major moisture remediation.
