Crawl Space Repair Photo Album: Crawl Space Repair in Thompsons Station, TN

John in Thompsons Station, TN, called to take advantage of Frontier's free crawl space inspection and estimate. During the evaluation, our design specialist found visible condensation and mold growth in the crawl space. Frontier cleared the insulation between floor joists and eliminated the mold with soda blasting. We then installed drainage matting and encapsulated the crawl space with CleanSpace liner to create a sealed, protected environment. A SaniDry Sedona dehumidifier was added to control humidity levels, and an EverLast door was installed to help keep outside air and moisture from re-entering the space.

Existing Crawl Space Door

This wooden crawl space door allows air to leak through, preventing a true seal for encapsulation.

Ground Moisture

Moisture is creating condensation below this vapor barrier. Without a proper seal, moisture is evaporating into the air from uncovered portions of the crawl space and through the crawl space walls.

Falling insulation

Insulation absorbs moisture, causing it to become heavy and fall. This is a clear signal of excess humidity in the crawl space.

Mold Growth

High moisture content in the crawl space has led to mold growth on floor joists.

Soda Blasting

This is the wood framing after soda blasting. The mold has been removed from the surface and the pores of the wood, creating a clean foundation before sealing the crawl space for long-term protection.

Drainage Matting

Drainage matting is installed beneath the CleanSpace liner to allow any ground moisture to move laterally underneath the system rather than becoming trapped.

Finished Encapsulation

With the floor, walls, and piers fully sealed, this encapsulation creates a controlled environment beneath the home, blocking outside moisture and protecting the structure long-term.

SaniDry Sedona Dehumidifier

With the wood cleaned and the crawl space sealed, a SaniDry Sedona dehumidifier was installed to pull moisture from the air, helping protect the soda-blasted floor joists and maintain a dry, stable environment.
