What is crawl space insulation?
Fiberglass batts between floor joists soak up moisture, sag and fall down. Once they do, floors get cold and your heating and cooling work harder.
Depending on your crawl space, a contractor may recommend insulating the walls (common with encapsulation) or using moisture-resistant insulation between the joists.
Signs you may need it
- Insulation hanging down or lying on the ground
- Cold floors in winter
- Damp or moldy insulation
- Rodent nests in insulation
What the work usually includes
Remove failed insulation
Wet, moldy or fallen batts are removed and bagged.
Choose the right approach
Wall insulation with rigid foam board or spray foam suits sealed crawl spaces; vented spaces need moisture-tolerant floor insulation.
Seal air leaks
Rim joists and penetrations are sealed for better comfort and efficiency.

Crawl Space Insulation FAQ
Should I insulate the crawl space walls or the floor?
If the crawl space is sealed and encapsulated, wall insulation is usually best. In a vented crawl space, insulation goes between the floor joists.
Why does my crawl space insulation keep falling?
Moisture makes fiberglass heavy. Fixing humidity first keeps new insulation in place.
