Crawl Space Repair in Mount Vernon, Virginia
Challenge
A family in Mount Vernon, Virginia contacted Fortress Foundation Solutions after noticing that several household members were suffering from worsening allergy symptoms, coughing, and persistent sinus irritation. The family had tried air purifiers and duct cleaning, but nothing seemed to improve the air quality. The home also carried a faint musty odor that became stronger during warm, humid weather.
During a crawl space inspection, the cause quickly became clear. The crawl space had exposed dirt floors, wet insulation hanging from the subfloor, and dark patches of mold forming on wooden support beams. Moisture from the soil was constantly evaporating into the crawl space, creating high humidity levels that allowed mold to thrive. Because warm air rises, this contaminated air was being pulled upward into the living space, affecting the entire household.
The family was especially concerned about the health of their children and wanted to ensure that their home was safe, clean, and free of airborne mold spores. They knew that simply cleaning the mold would not be enough unless the moisture problem was fully addressed.
Solution
Fortress Foundation Solutions designed a permanent crawl space encapsulation system to eliminate moisture at its source. The team installed the CleanSpace® Vapor Barrier, fully covering the dirt floor and sealing it up the crawl space walls and support piers. This thick, durable liner blocks moisture vapor from rising out of the ground and isolates the crawl space from the damp earth below.
To ensure the air remained dry and healthy, we installed the SaniDry™ Sedona Dehumidifier. This powerful system continuously removes excess humidity while filtering mold spores, dust, and allergens from the air. With humidity under control, mold is unable to grow, and the crawl space becomes a clean, stable environment.
After the installation, the musty odor disappeared, humidity levels dropped, and the family noticed a significant improvement in their indoor air quality. Their home became healthier, more comfortable, and fully protected from crawl space moisture.
