Crawl Space Repair Photo Album: Crawl Space Repair in Franklin, TN

Emily in Franklin, TN, contacted Frontier because she was worried about moisture in her floors and wanted a home she could leave to her children. The design specialist found open vents contributing to a relative humidity of 69% in the crawl space. Soda Blasting was used to remove existing mold. Drainage matting and CleanSpace liner were used to encapsulate the floor, walls, and piers. A SaniDry Sedona dehumidifier was installed to control humidity long-term, and the old crawl space door was replaced with an EverLast door to seal the space from outside air.

Crawl Space Entrance

The existing crawl space door allows air to travel inside through gaps in the wood, which will raise the humidity inside.

Open Vents

Unsealed vents allow humid air to enter the crawl space, raising relative humidity in the summer. In the winter, warmer air entering the space can hit cold ducts, pipes, and walls, leading to condensation.

Falling Insulation

Insulation absorbs moisture from the air and becomes heavy, often falling out of place. This keeps moisture close to the floor joists and reduces the effectiveness of the material.

Relative Humidity

The RH in this crawl space was 69%, higher than the 60% threshold that allows mold to grow and attracts pests.

Soda Blasting

The insulation was removed from between the floor joists, and soda blasting was used to remove mold at the source while helping create conditions that discourage future growth.
