Mold Problems Photo Album: Crawl Space Repair in Nashville, TN

Chad in Nashville, TN, contacted Frontier after becoming concerned about the safety of his home. He had noticed weak spots in the subfloor, and one area had shifted enough to cause a window leak. During the inspection, the design specialist found that the existing sump pump had failed, leaving standing water in the crawl space and creating conditions for severe mold growth. Because of the moisture damage, part of the flooring system needed to be replaced. The remaining subfloor and floor joists were sprayed with MoldX to kill and prevent mold. Frontier installed SmartJacks beneath the sagging areas to lift and stabilize the floor. To address the water intrusion long-term, the crew installed a perimeter drainage system connected to a TripleSafe sump pump. The crawl space was then encapsulated with drainage matting and CleanSpace liner to help isolate the home from ground moisture and create a healthier environment below the home.

Broken Sump Pump

The sump pump was not effectively removing water from the crawl space. Additionally, the lack of encapsulation and the open vents create a continuously humid environment perfect for mold growth.

Standing Water

Due to the failed sump pump, standing water had accumulated at the edges of the crawl space.

Mold Growth

The mold on the floorboards has compromised the strength of the floor and must be replaced.

Effects of Sinking Floors

The lack of support underneath the home has caused cracks to form near doors and windows.

Drainage System Installation

Standing water in the crawl space was addressed with a drainage system. The orange mesh over the pipe allows water to enter the system while preventing dirt from entering and clogging the system.

New Subfloor

After the compromised subfloor is removed, Frontier replaces it with new subflooring to restore support and stability. Once the structural repairs are complete, the homeowner can move forward with replacing the finished flooring above.

Disposing of the Compromised Subfloor

The Frontier crew removed the moldy subfloor that no longer supported the floor.

Drainage Matting

Once the drainage system is installed, drainage matting is installed underneath the liner. This matting allows water to flow laterally towards the drainage system.

Full Encapsulation with Sump Pump and Dehumidifier

The drainage system directs water towards the sump pump for removal. The SaniDry Sedona dehumidifier is installed to remove any remaining humidity from the crawl space.
