Cold Floors, Vented Crawl & Exposed Rim Joists in Shrewsbury, NJ

We discovered why a homeowner in Shrewsbury, NJ, struggled with cold floors and an uncomfortable home. The vented crawl space and exposed rim joists were allowing cold air to infiltrate, creating chilly floors and uneven temperatures in the rooms above. This setup also risked moisture and humidity buildup, potentially leading to mold growth. Although the crawl space had a proper vapor barrier, the vents remained unblocked, and the rim joists were unprotected. To fix this, we installed foam blocks to cover the vents and insulated the rim joists, sealing everything with foam sealant. Finally, we used spray foam to close any remaining gaps letting in outside air. Now, the homeowner enjoys a warmer, more energy-efficient home.
