Crawlspaces & rim joists
Comfort starts below your floors, too.
Serving Macomb, Oakland, Wayne & St. Clair counties

Comfort starts below your floors, too.
We help improve crawlspaces and rim joists with insulation, air sealing and vapor barrier or encapsulation options. The right scope depends on access, existing conditions and the way the space is built.
- Crawlspace perimeter insulation where appropriate.
- Vapor barrier and encapsulation options.
- Rim joist insulation and air sealing.
- Preparation and removal requirements discussed in the estimate.
Is encapsulation the same as insulation?
They address different parts of the space. Vapor barriers help manage moisture movement, while insulation helps reduce heat transfer. Your project may call for one or both.
