Case Study: Foundation Repair and Encapsulation in Sumter, SC

Crawl space with plastic vapor barrier on the floor and insulated air ducts above.

A Sumter, SC, homeowner contacted Mount Valley Foundation Services after a masonry contractor noticed foundation issues while rebuilding the front porch stairs. The home exhibited signs of settlement and wall cracks, which needed to be addressed before the porch work could proceed. Addressing the foundation first ensured the new porch would be structurally sound and prevented further damage to the home.

Mount Valley Foundation Services resolved this issue with tailored foundation repair and encapsulation solutions. Here’s how:



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.

My husband and I had a great experience with Mount Valley! Brandon did our initial consultation. He was timely, thorough, and answered all our questions professionally. We had work done on two separate days and again everyone who showed up had amazing customer service. Will, Jimmy, Ober, Austin, and Michael all answered any questions we had without making us feel like we were in the way. They actually encouraged us to ask questions and watch the process to make sure we understood what was happening to our house. I also have peace of mind about my home with the transferable warranty.

Nathan and Morris provided excellent service installing additional jacks in my crawlspace. They were punctual, professional, and finished ahead of schedule. While a previous salesperson recommended the extra jacks to fix my shifting baseboards, Nathan (the job manager) took the service to the next level. He used a laser to precisely measure a 1.5-inch drop and actually modified the placement of the new jacks for better support. He was incredibly thorough, taking photos under the house and explaining that the builder had spaced the original beams too far apart on one side of the home. Nathan was the first person to explain the root cause of my structural issues in such detail. He set up a plan to raise the house gradually over the next three months to avoid damage and even gave me a heads-up that we might need steel reinforcement in the future due to the wide span of the wooden beams. I truly appreciate the expertise and efficiency—great job!"

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.
