Anderson was very informative on the step by step process for a crawlspace encapsulation and installation of a dehumidifier. He provided pictures of the areas that need taken care of. The crew Darrell, Andrew and EJ were great! Darrell called every morning to let me know they were on the way. He let me know the progress they were making and the issues he saw. When the job was complete he send me the pictures of the final encapsulation and dehumidifier. It looks amazing! They were very professional and polite.

We had Mount Valley Foundation complete a foundation repair on February 9, 2026. Kevin A, Chris W, and Mason T, were the workmen who completed our job. They were polite, attentive, and worked like a well-oiled machine. They had great attention to detail, replaced yard items that had to be moved, and even raked the marks left by their equipment. I have rarely seen a team that did as good.

I want to commend the outstanding work of Will Soulier (Foreman), Jimmy Bracey IV, and Myshaun Joyner. This crew recently installed eight foundation piers–six on my property and two at my neighbor's–to prevent further settling. Their performance, professionalism, and attention to detail exceeded every expectation. Despite a mid-project equipment failure, Will quickly diagnosed and resolved the issue, minimizing downtime and keeping the job on track. His leadership was confident, calm, and efficient. Jimmy and Myshaun worked with focus, precision, and a strong sense of purpose–even while managing the challenge of my home's low-amperage breaker constantly tripping. Without the need to consult their foreman, they remained proactive and task-oriented, clearly taking full ownership of their roles. Both demonstrated strong leadership potential. Equally impressive was their demeanor throughout the day. They were respectful and patient around my children and tolerant of my presence as I observed the work. When my curiosity prompted questions, they each took the time to explain the process with professionalism, friendliness, and deep knowledge. They maintained clear attention to safety at all times and were remarkably considerate of my property–protecting the lawn, landscaping, and fixtures with great care. The fact that they completed the full scope of work in a single business day, with quality and efficiency, speaks volumes about their coordination and work ethic. This crew represented their company with integrity, craftsmanship, and pride. Their work and conduct reflect the highest standards, and I couldn't be more impressed with the outcome.

Will, Andy and Ober could not have been better! We had to have some foundation piers and crawl space supports installed. They actually called and asked if the could come a day earlier than expected. They were professional and courteous from the time they showed up until the time they completed the job. They kept us informed of any problems and the status of the work. Could not have had a better experience from the time that Dan quoted the job to the completion of the work. Would highly recommend Mt Valley/Groundworks for any foundation or crawl space work!

Wow guys: Will S., Jimmy B., Ober L., Austin C… From the start of the project you all walked us through what was going to happen. During the project you kept us reassured by showing us the progress. At the end of the project you cleaned up and filled us in on the success of raising our foundation on one side of our house in Myrtle Beach. Great job. I highly recommend Mount Valley Foundation for anyone needing this type of work done. Leesa and Mac

The Charleston office team is professional, responsive to questions, and thorough in consultation with photos and diagrams to problems with our foundation. The team who performed the work were on time, worked all day, reported any problems and offered solutions. Pleased with the quality of work. Our problem was sagging floors due to lack of foundation support beams in a post and beam construction. The building code requirements 20 years ago was inadequate to support the house over time. We had several I beams installed with supporting jacks to level the foundation and prevent further sagging.

I reached out to Mount Valley Foundations and asked them to send someone out to evaluate my crawl space and provide me a quote for a full encapsulation. An appointment was set and Patrick showed up to our house as scheduled. He completed a thorough inspection, then sat with us for over an hour explaining in detail what he saw. He provided pictures taken under our house and used slides/videos to educate us on encapsulation. Patrick was very professional, answered all our questions and guided us through our financing options. From there, we were placed on the schedule for install. Derrick and TJ were the team they sent for our project. They called us the morning of to let us know they were on the way. When they arrived, Derrick explained what they were going to do each step of the way and got right to work. The encapsulation took a little over two days. On the last day, Derrick took me into the crawl space and made sure I was happy with the installation. Rarely do finished products look like the marketing photos, but this was the exception; everything was meticulous! I'm in residential construction by trade so I'm somewhat familiar with air sealing techniques and this job was done with care. Thank you to Derrick, TJ, Patrick and the entire team at Mount Valley Foundations!

A week before Christmas, I had a rat invasion in the crawlspace that was encapsulated by Mount Valley. Marge came out several times to help me cover the holes where a rat had eaten through the encapsulation material. She was great!! I highly recommend Mount Valley and their great customer service! Marge should be commended for her excellent tireless efforts to help me with my problem. We are now rat, free and encapsulation has now been restored back to normal.
