Crawl Space Insulation
The right insulation reduces energy costs by up to 20% and eliminates cold floors above the crawl space.
What is Crawl Space Insulation?
Proper crawl space insulation is essential for energy efficiency and comfort. In encapsulated (sealed) crawl spaces, insulation is applied to the perimeter walls rather than between floor joists — creating a conditioned space that maintains more stable temperatures. For vented crawl spaces, floor joist insulation helps, but encapsulation with wall insulation is the superior long-term solution. Professional installation ensures proper material selection, coverage, and integration with vapor barriers.
Key Benefits
- Reduces heating and cooling costs by 15-20%
- Eliminates cold floors in winter
- Prevents frozen pipes in the crawl space
- Reduces HVAC system strain
- Improves whole-home comfort
- May qualify for energy efficiency tax credits and rebates
Our Process
Assessment
Current insulation condition is evaluated, and heat loss areas are identified.
Old Insulation Removal
Damaged, wet, or inadequate insulation is removed and properly disposed of.
Method Selection
Based on your crawl space type (sealed vs. vented), the right insulation method is chosen.
Installation
Insulation is installed — either spray foam or rigid board on walls (sealed crawl spaces) or batts between joists (vented).
Air Sealing
Gaps around penetrations, rim joists, and transitions are sealed to prevent air leakage.
Typical Cost
$1,500–$5,000
Factors That Affect Your Cost
- Insulation type (spray foam vs. rigid board vs. batts)
- Square footage of coverage
- Old insulation removal needs
- Crawl space accessibility
- Local labor rates
- R-value requirements per local code

Crawl Space Insulation FAQ
In an encapsulated crawl space, insulating the perimeter walls is recommended — it creates a conditioned space and is more energy-efficient. Floor joist insulation is used in vented crawl spaces but is the less effective approach. Modern building science strongly favors sealed + wall insulated.
