Crawl Space Repair Photo Album: Mold Removal and Encapsulation in Brentwood, TN

Cindy in Brentwood, TN, contacted Frontier because she was concerned about moisture in her crawl space. The design specialist found standing water, 80% relative humidity, and mold growth on the floor joists. The insulation had absorbed moisture and was falling out of place. Frontier installed a drainage system and TripleSafe sump pump to collect and remove the standing water. The crew used soda blasting to remove mold from the floor joists, then encapsulated the crawl space with Drainage Matting and CleanSpace liner. A SaniDry Sedona dehumidifier was installed to control humidity.

Insulation Falling

The insulation in the crawl space was absorbing moisture from the air, causing it to become heavy and fall out of place.

Crawl Space Humidity

Relative Humidity in the crawl space exceeded the recommended limit of 60%, where mold thrives on organic materials.

Soda Blasting

Soda blasting was used to remove mold from the floor joists, leaving the wood like new.

Drainage Installation

Drainage was installed around the perimeter of the crawl space to collect water as it enters from the outside.

Drainage Matting

Drainage matting is installed underneath CleanSpace to prevent punctures from rocks underneath the liner during maintenance.

Finished Encapsulation

The crawl space was fully encapsulated with a 20-mil-thick liner to prevent moisture intrusion.

SaniDry Sedona Dehumidifier

The SaniDry Sedona Dehumidifier removes water from the air and discards it into the sump pump for removal, resulting in relative humidity levels under 60%.

TripleSafe Sump Pump

The triple safe sump pump with battery backup was installed to remove water from the drainage system. The battery backup ensures continuous removal even during a power outage.
