About Mount Valley Foundation Services
Mount Valley Foundation Services maintains a 4.6-star average across 591 customer reviews in Spartanburg, South Carolina, positioning itself as a major foundation and waterproofing contractor in the Upstate region. Operating under the Groundworks national network, the company serves homeowners throughout Spartanburg County and neighboring communities including Greenville, Anderson, and the surrounding areas. The business focuses exclusively on below-grade home infrastructure, distinguishing itself from general concrete contractors by specializing in foundation repair, crawl space solutions, and basement waterproofing systems.
What distinguishes Mount Valley is its systematic approach to moisture management and foundation stabilization. Reviewers consistently mention the company addresses underlying structural issues rather than surface symptoms, with installation teams completing comprehensive repairs in single visits when possible. The firm utilizes professional sales representatives who provide detailed project explanations and, per customer feedback, clearly communicate permit requirements and available tax credit information before work begins.
Multiple reviewers specifically named installation technicians who delivered exceptional service. A crew led by Ron, along with team members Koby and Jacob, completed both a crawl space encapsulation and a basement waterproofing project within one day, with one homeowner noting humidity problems were eliminated almost immediately. Another reviewer praised sales team member Carlton for professionalism beginning at first contact, while a third noted technician Dustin provided accurate information about city permits and tax credits when competitors supplied incorrect guidance.
What Customers Say
Of 591 reviews, two customers specifically mention crawl space encapsulation with dehumidifier installation as resolving persistent humidity problems, while three five-star reviews name technicians Ron, Koby/Jacob, and Carlton as standout team members. The single one-star review describes a dispute over moisture barrier scope and pricing escalation.
