Mark Duncan came by to inspect my footer drain and sump pump that was installed 2 years earlier. After identifying issues that was preventing proper drainage he came back out after hours and fixed my problem. Mount valley has done a great job at hiring good people and I’m thankful Mark was the one that was taking care of my problem. Mark was the perfect example of standing by the work of his company!

This review is for Jon Geddie with Mountain Valley Foundations, and I truly cannot say enough good things about our experience. From the very first phone call, Jon was professional, courteous, and attentive. When we scheduled the appointment, he showed up exactly when he said he would — which already speaks volumes about his character. But what really impressed us was what happened next. Jon didn’t just “look around” and throw together a quick estimate. He took his time — real time — to thoroughly inspect everything. He crawled underneath the crawlspace, carefully examined the foundation, inspected the cross members, and checked every area where there could potentially be an issue. He was methodical, detailed, and incredibly thorough. It was clear he genuinely cared about understanding the full scope of the situation rather than just selling a service. We originally reached out for an estimate on encapsulation, but Jon made sure no stone was left unturned. He explained what he was seeing in clear, understandable terms — not technical jargon that leaves you confused. He broke down the pricing step by step and walked us through financing options that are available. There was zero pressure. Just honesty and information. What really stood out to us was his integrity. Jon didn’t rush us. He didn’t push us. He didn’t make us feel like we were “just another job.” He gave us space to think, answered every question patiently, and made sure we were comfortable and confident in what was being discussed. He even pointed out additional services and features the company offers that could benefit us in the future — not in a sales-driven way, but in a helpful, informative way. Beyond his professionalism, Jon is simply a great human being. He is knowledgeable, respectful, well-mannered, and genuinely pleasant to be around. We actually sat down and enjoyed lunch together while he was here, and at no point did he seem rushed or distracted. That speaks volumes. In today’s world, it’s rare to meet someone who blends professionalism with such authenticity and kindness. Jon is reliable, trustworthy, and follows through on what he says he will do — and then goes above and beyond. You can tell he takes pride in his work and in representing Mountain Valley Foundations the right way. If you are considering any foundation work, encapsulation, or related services, I wholeheartedly recommend Jon Geddie. It’s not often you come across someone who combines expertise, integrity, and genuine care the way he does. We are grateful for the time he spent with us and the confidence he gave us moving forward. Outstanding experience from start to finish.

Excellent is an understatement!!! Really it is I have never this far in my life ever meet such honest, professional, communicating, helping you to understand the process you are going into in my life. These people are definitely heaven sent. They take time to walk you through every step, show you pictures of what's going on and what has been done. Chris was very highly informative when coming out to give my estimate. And the crew Shawn and Alex I couldn't ask for better!! Goggle only allows 5 stars. These guys get 20 stars from me!!! Keep doing your excellent work!!!! Glad they were the ones I got sent!!!! Thank you Mt. Valley

5 star review but the Only issue is that 2 of the guys that were here working was using real bad language thankfully my children weren't around but they were yelling and using it across my yard at each other so my neighbors with small kids most likely heard them . They also left nail gun nails all in my driveway which could of been bad if myself or someone else ran them over. They left some trash throughout my carport.

I had a great experience with Mount Valley when they repaired my foundation recently. The team was cohesive, professional, courteous and I highly recommend them. I was more than happy with the results and the efficiency of the team…. Especially Oscar, Billy, and Kemper who did the bulk of the work – They were excellent on the first day and left me with confidence that everything was going to go smoothly! (Great young men!) I also dealt with Jack, Dalton and Joshua… The whole team exceeded my expectations and it should be noted that their demeanor and customer relations were fantastic! Highly recommend!!! C. Alexander

Mount Valley Foundation Services made this a much easier process than I anticipated. Trey was super responsive and informative. Josh, Zion, and Daizon were communicative, courteous, and efficient while working on my house. They were professional, quieter than expected, and cleaned up around the work area quickly and thoroughly. I can't recommend them all enough if you need foundation work done.

I am very pleased with the work recently performed by Yiannis and Landon. After damage from Hurricane Helene, my home needed helical piers installed to provide additional foundation support. They also performed a SettleStop PolyRenewal project to take care of settling issues with my front steps and walkway. They kept me informed of all the steps involved and made sure I was satisfied with the results.

Structural Repair Specialists in Sumter

Commonly known as the ‘Gamecock City,’ Sumter is situated near the geographical center of the state. As the 8th most populated city in South Carolina, homeowners enjoy their homes. However, the hot, humid summers and relatively low precipitation levels can cause problems for foundations throughout Sumter, and the surrounding areas of Wedgefield, Mayesville, Alcolu, and Dalzell. 

So, if you notice your homes sinking or settling, or smell a musty odor coming from the crawl space, act quickly. Moisture and water vapor in a crawl space leads to mold growth, noticeable by the pungent smell upstairs. Though mold can be more than annoying. Mold can weaken the support posts and put your home at risk. 

Uneven and cracked concrete slabs are another common problem for homeowners. The Sumpter area has soil that is well-drained, that means it shrinks during dry conditions, leading to unsupported concrete driveway or sidewalk slabs that crack and sink. 

The weather and the soil surrounding your foundation cannot be changed; however, there is a solution. Mount Valley Foundation Services understand your areas unique qualities because we live and work in your community. We offer the best foundation, basement, crawl space, and concrete solutions.
