Crawl Space, Basement & Rim Joist Insulation
Stop moisture, drafts, and energy loss at the foundation level with professional spray foam insulation.
The Foundation Is Where Problems Start
Crawl spaces, basements, and rim joists are among the most overlooked areas for insulation, and some of the biggest sources of energy loss and moisture problems in Wisconsin homes. Cold air infiltrates through foundation gaps, rim joist cavities, and uninsulated crawl space walls, driving up heating costs and creating conditions for mold and moisture damage.
Why Spray Foam Is Ideal for Below-Grade Spaces
- Moisture barrier built in - Closed-cell spray foam prevents ground moisture from penetrating into your living space.
- Rim joist sealing - Rim joists are one of the biggest sources of heat loss. Spray foam seals them completely.
- Draft elimination - Stop cold air from entering through foundation cracks and gaps.
- Mold prevention - By controlling moisture, spray foam removes the conditions mold needs to grow.
- Warmer floors above - Insulating the crawl space makes first-floor living areas noticeably warmer.
