Before Foundation Repair:

Foundation Settlement and Cracks
Foundation settlement was discovered during the repair of the front porch stairs. A free inspection revealed vertical and horizontal cracks caused by settlement beneath the porch and outer wall, posing a risk to the home’s structural integrity and value.

Crawl Space Humidity and Moisture
The closed crawl space harbored excess moisture, a common issue in humid Sumter, SC. Left unaddressed, high humidity weakens structural framing, causes wood rot and mold growth, and contributes to foundation settlement.
After Foundation Repair:

Foundation Stabilization
To stabilize the front porch, the team installed 10 helical piers beneath its columns. For the home’s foundation, which exhibited vertical and horizontal wall cracks due to settlement, they installed eight push piers under the front wall. Both systems redirected structural loads to stable soil, restoring support and protecting the home’s value.

Dry, Encapsulated Crawl Space
The Mount Valley team encapsulated the crawl space with a vapor barrier and added vent covers and crawl space doors to seal the area. The team also installed a dehumidifier system, complete with a duct kit and condensate pump, to maintain low humidity levels and keep the space dry and mold-free.

Foundation Repair FAQs
Foundation piers are typically a permanent solution. Once installed correctly by a reputable foundation repair company, high-quality foundation piers can last for the lifetime of your home. Unlike temporary fixes such as patching or filling cracks, foundation piers provide a long-term solution to foundation problems and prevent future damage.
When properly installed and maintained, crawl space encapsulation can last 15 to 20 years or more. The vapor barrier, a key component of encapsulation, typically has a lifespan of 20 to 25 years. However, longevity can vary based on factors such as installation quality, climate conditions, and regular maintenance. With proper care, some encapsulation systems can even last the lifetime of the home.
Foundation piers attach to your home’s footing. If your home doesn’t have a closed footing, modifications can be made. Consult a qualified foundation repair expert to help ensure your foundation is properly evaluated and factors like soil composition and local building codes are considered.
