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

Mandi in Clarksville, TN, called Frontier after noticing uneven floors and cracks forming throughout her home. During the inspection, our design specialist found moisture intrusion in the crawl space along with failing support systems contributing to the structural issues. To restore the space, the crew first treated the area with Mold X to eliminate existing mold growth. A drainage system was then installed and connected to a TripleSafe sump pump to manage future water intrusion. The failing supports were removed and replaced with SmartJacks to stabilize the floors above. Finally, the crawl space was fully encapsulated, and a SaniDry Sedona dehumidifier was installed to control humidity and protect the home in the long term.

Existing Mold

Mold was growing on the floor joist. Without treatment, this mold will spread and compromise the strength of the wood.

Mold-X treatment

The crews removed the insulation and sprayed the wood with Mold-X, a mold killing solution.

Efflorescence and Condensation

Water intrusion was evident in the crawl space. Efflorescence was visible on the foundation wall, indicating that water had moved through the concrete and evaporated. Water was also present beneath the unsealed vapor barrier, allowing moisture to escape through the exposed edges.

Preparing for the Drainage System

The crew must create a trench system to install the StarPipe drainage pipes.

Drainage System

The drainage system was installed in the lowest areas of the crawl space to prevent standing water. It was placed around the supports to keep the soil dry and stable, helping reduce the risk of further settlement.

Smart Jack Supports

SmartJacks were installed to replace the failing supports. These systems lift and stabilize the floors above, helping prevent further sinking. While the drainage system works to control moisture, the jacks can also be adjusted over time if any additional settlement occurs.

Sealing the Space

Vents and gaps are sealed with RimTite Joint Insulation and SilverGlo panels. This system prevents humid air from entering the space.

Water Heater

Water heaters are notorious for leaking. A lip is created so any leaks will flow into the drainage system.

Completed Encapsulation

The space is fully encapsulated, and moisture cannot enter from the floor or walls of the crawl space. A SaniDry Sedona dehumidifier was installed to prevent any remaining humidity.

TripleSafe Sump Pump

A TripleSafe sump pump is connected to the drainage system to discharge water. It connects to a battery backup that is activated during power outages.
