Mount Valley Foundation was a pleasure to work with from the Salesperson to the Installation Personal. During the installation process, Yiannis Kokolis and Landon Wray were very helpful and listened to concerns. They addressed everything and work with me during the installation. Customer service was on point with them and even on the follow up call after.

Installation of sump pump and drainage system to expel ground water seepage. The entire team from initial contact through installation was a professional and accommodating as I have ever encountered. We were completely satisfied with the cost involved. It was more than fair given the services rendered. Davd E and Kim R

Donovan and his crew were totally responsive to my text communication. He followed through and came by and fixed my issue in minutes. He is one of the best contractors we've worked with in terms of communication and taking the time to do the job right. Every company needs a Donavan. In fact, do yourself a favor and get yourself a Donavan this holiday season.

I had my home inspected on October 17th by Edgar Velasco, Spartanburg Office. I wanted to advise how professional he was in his job, and sitting down with us to go over the solutions to our foundation issues. He wasn't pushy to us about making a decision right then. That's what I like about a company. Once we are able to get out FEMA approved, we will definitely have Mount Valley do the work. Thank you.

Mount Valley Foundation did a wonderful job on our crawl space. From the beginning, Clint was very easy to understand & gave us affordable options. The encapsulation only took 3 days & the crew finished up the third evening at 7:00 pm, just in time before Helene came. Our home usually would have flooded during a storm like this, but with Mount Valleys installation of the draining pipes, the water was pumped out successfully. The crew that did the installation was wonderful as well, thank you to Donovan Rougeaux, Isaiah Davis, & Cory Phillips for the quick installation.

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

Mr. Daniel Herren is the best foundation specialist I’ve spoken too. He covers all possibilities of how it could happen, fixing etc. Mr. Herren is a professional and is not there to make money. I’m not being paid by this company and it was just an estimate, the way they handled themselves is the reason I wanted to recognize them and more importantly Mr. Herren.

Struggling with water seepage in the lower level of our house, I wanted to fix the problem once and for all and called Mount Valley. The inspector, Scott, did a detailed review, took the time to discuss everything, and made certain that my questions were answered. He also responded to follow-up questions that I had a few days later. Familiar with sump pump installations, having had one in a prior home, I became convinced that it would be the best way to ensure the problem would be solved. The initial installation schedule was farther out than I wanted, as we were trying to get ready for an influx of family, but MV was able to move us to an earlier date when they had a slot open up on their schedule. The installation foreman, Durand, worked with me to resolve site issues even though it meant another visit a few days later. The final installation was accomplished as Durand, Ron T, and Patrick worked past normal hours as the sun was going down to get the job done. In the end, I was grateful for a professional job by the MV team and the courtesy extended by everyone throughout. They are deserving of a fine review.

We are very thankful that we selected Mount Valley to raise and align the concrete slabs in our garage and sidewalk. Dustin came in july and gave us a very careful estimate and was extremely polite and helpful. And today, Yannis came and worked all day on the job raising and aligning the slabs in the garage and the sidewalk. He was extremely courteous and he was totally dedicated to making us happy with his work- – he did an excellent job!!

Mount Valley completed a driveway repair which involved foam lifting of sections that had settled as much as 2-3 inches. Clearly having great expertise, Yiannis went above and beyond to make sure that no tripping hazards remained by beveling some of the edges. I would highly recommend Mount Valley Foundation.

Mark Duncan completed my annual service today on the pump and dehumidifier. He was extremely professional and very thorough. I had some issues over the first year and were ultimately fixed. Mark’s attention to detail gives me hope of many more years with MVF.

From start to finish Mount Valley Foundation did an amazing job. My husband and I just moved from WI into a 1950s home. We would set our AC to 70 and the humidity would make it 85 in the home. We got a few different quotes and made our choice. As a first time home owner it’s always scary trying to find the right pick but Shaun, Dre, and Alex were all very informative about what they were doing and was always patient about me asking questions. After a day of completion we now stay at a nice 70 degree home with low humidity.

Very pleased to have picked Mt. Valley to do the necessary work to raise my sinking deck. Carlton Cisson was my inspector, and Mr. Nesbitt, Mr. Miller and Mr. Hernandez did the great work. The whole group were meticulous, polite and very hard working. I dreaded the whole process but it turned out to be a very good experience thanks to these guys. 🙂

Mount Valley came out today to fix my front walkway that had settled and was uneven. Yiannis and Landon were very nice and did a great job with my walkway. They answered my questions before they started and cleaned up after they were done. They were very pleasant to do business with. I would definitely use Mount Valley Foundation again. Thank you!

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.

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. Repairs can be customized to fit your home and your lifestyle.
