Crawl Space Insulation in Columbia, TN

Insulate the walls of a sealed crawl space instead of the subfloor above it.

In an encapsulated crawl space the insulation goes on the foundation walls, not between the floor joists. The sealed space is inside the building envelope, so insulating the walls keeps the whole volume closer to house temperature.

Fibreglass batts stapled between joists are the traditional approach and they fail predictably in a damp crawl space: they absorb moisture, get heavy, and fall out. Finding batts on the ground is a reliable sign the space has a moisture problem that predates the insulation failing.

Typical cost: $1,500 - $5,000 depending on wall area and material

When crawl space insulation is the right call

• Cold floors above the crawl space in winter
• Existing batts sagging or on the ground
• As part of a full encapsulation, once the space is sealed
