I recently had foundation work completed by Mount Valley Foundation at my property, and I could not be more impressed with the results. From start to finish, the team, Jarrod, Mason, and Kincade demonstrated exceptional professionalism, expertise, and attention to detail. They thoroughly inspected the issue, clearly explained the underlying problems, and offered a practical plan that fit both my needs and budget. The three man crew arrived on time each day, worked efficiently, and kept the work area clean and safe. They communicated progress throughout the project, which gave me a lot of confidence in the process. Once the work was complete, they walked me through everything they had done and made sure all my questions were answered. The quality of the repair is outstanding—my home feels more stable, the cracks have been addressed, and I have peace of mind knowing the foundation is solid for the long term. It’s rare to find a company like Mount Valley Foundation that combines skill,

Darrell and his crew members, Derrick, and Dorrian, did a good job. They were courteous, on time, keep me informed, and keep the job site clean. Their supervision, DA, also did a wonderful job.

These guys were professional. Explained what they were going to do and. They kept us i formed through the project. I believe it was Joe that let me stand next to him when the other guys were making final adjustments to lift my laundry room so that I could see my laundry door close for the first time.

I'm very dissatisfied with this company as a whole. After giving my deposit, I was told they would be to my home on a set date and time. They didn't show up on set date and didn't call or text as to why no one showed up. After calling several times, the next day someone calls apologizing profusely but gave no reason as to why the workers didn't show up. When you finally get them to come, they start the project and then the cat and mouse games begin! They'll call and say they have to finish another project and would be there a little later and then call back because that other project ran longer than expected. It's now 4 months into what I was told would be no more than a week! Calling the company itself about what's going on or complain is absolutely impossible, if someone does answer the phone, they give you the run around. Parts of my electrical was messed up by their worker, I was told that they would take care of it right away. Lies, lies and more lies with this company!

I have had the worst experience ever with this company. Extremely poor customer service. The sales representative Michael Cox, attempted to talk down, insult my mother and I, was extremely rude, and tried to bill us for services that have not been rendered. He scheduled services to be completed without running any dates by us. He is a disgusting want to be con man. As a company they should not want anyone like him working for them. I would never trust this company, nor would I recommend this company with their illegal practices. I'm hoping this company doesn't make us take them to small claims court.

I have been a very dissatisfied customer since July of 2022. From the very beginning, the follow up, customer service and quality of work has been beyond sub par. I have had an extremely hard time getting your company to follow through with work it is contracted to do. When yet another employee failed to do an inspection of my crawl space. I called. The receptionist refused to give me contact information for the general manager so that I could send him a detailed email outlining all of my concerns. She said a manager would call back today but that did not happen either.

I don?t normally leave reviews, but I feel like other families deserve to know what we went through with Mount Valley Foundation Services (Charleston office). We hired them to repair subflooring in our home. The result was honestly shocking. The new subfloor was so uneven that flooring couldn?t even be installed?something both the city inspector and a licensed contractor confirmed. A section of rotted subfloor was left in place, and instead of replacing it, they added a board underneath, hidden from view. My husband ended up falling through this section and getting injured. On top of this, the power to our house was cut during the job and no one informed us. I was 8+ months pregnant and we were left without access to our home for days. The whole situation forced our family (including our toddler and dog) to live out of temporary housing while we figured out repairs. The new contractor that we hired did a beautiful job and charged us far less than Mount Valley.

I hired Mount Valley (Charleston) for subfloor repair, but the work failed inspection, left rotted wood in place, and caused structural collapse. My family was displaced, I fell through the floor, and I had to hire another contractor to redo everything. Communication was poor, and their refund offer didn?t come close to covering damages. I do not recommend this company.

We recently had foundation work completed by Mountain Valley Foundation Services, and we can’t say enough good things! The level of professionalism, attention to detail, promptness, and work ethic deserves ten stars! Specifically, Will, Jimmy, and Myshaun were excellent to work with!
