Before and After Pictures from Occoquan
Vented Crawl Space

Vented Crawl Space

Before After
Vented Crawl Space Vented Crawl Space

The floors over the crawl space of this Occoquan home were cold in the winter. We found that the crawl space was vented and suffered from mold growth and damaged insulation. We sealed the vents, removed old insulation, and added TerraBlock to the dirt floor. We also installed 20 mil. CleanSpace anti-microbial vapor barrier and insulated the walls as a final touch.

Job Stories From Occoquan, VA
Customer Question: How Do I Stop This Moldy Smell Coming Up From My Crawl Space?

The Northern VA climate, especially in the late spring and summer, yields very humid conditions. This moisture in the air, combined with a dark, still crawl space with wood or fiberglass insulation is a perfect breeding ground for mold. It will thrive in these conditions and, if left unaddressed, can start to seriously affect the air quality and safety of your home. That smell can actually contain spores from the mold that can cause allergic reactions and health problems. To combat this, the mold needs to go away - permanently. Simply applying a fungicide will be a short term solution - it will come back in these conditions. Encapsulating and dehumidifying your crawl space is the best possible way to stop the return of mold and moldy smells. 

Our CleanSpace vapor barrier is great for encapsulating the crawl space: it protects from moisture that seeps in through the walls, floor, and outdoors. A dehumidifier, like our Sedona SaniDry, will handle any remaining moisture that might be in the air. Dry conditions will make the crawl space less likely to develop mold and thus will stop that gross smell from coming up through your floors.
