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

Larry in Fairview, TN, contacted Frontier after noticing bouncing floors throughout his home. The home had a mix of construction types, including metal undercarriage, slab, and wood floor joists. During the inspection, the design specialist found signs of moisture in the crawl space, including mold on the floor joists and efflorescence on the walls. The relative humidity was measured at 68%, well above the 60% threshold where mold can thrive. To address the mold, the Frontier crew soda blasted the wood floor joists and floor boards to create a clean surface. SmartJacks were then installed beneath the home to stabilize and lift the floors, reducing bounce. To control moisture, the crawl space was fully encapsulated using drainage matting and CleanSpace liner. A SaniDry Sedona dehumidifier was installed to lower humidity levels, and an EverLast door was added to properly seal the crawl space and complete the system.

Old Crawl Space Door

The existing crawl space door was not properly sealing the space, allowing humid air to seep in and contribute to moisture issues.

Efflorescence on Crawl Space Walls

Efflorescence is a sign of moisture intrusion in a crawl space. Efflorescence is the white, chalky substance left behind when water passes through concrete and evaporates.

Mold on Floor Joists

Mold was growing on the floor joists, softening the wood over time.

Relative Humidity

The RH in the crawl space was over the 60% threshold where mold is activated.

Soda Blasting

Soda blasting reaches into the pores of the wood to remove mold at the surface. After the process is complete, the air is scrubbed and filtered to help remove airborne mold spores from the space.

Drainage Matting

An encapsulation begins with drainage matting, which allows water to move laterally beneath the liner and helps protect the liner from damage during crawl space maintenance.

CleanSpace Liner

CleanSpace liner is used to encapsulate and seal the crawl space. The walls and piers are sealed first, then the floor liner is installed and connected to create a continuous barrier. This helps prevent openings where moisture can enter.
