What a fantastic company!! Chip was a delightful help in guiding the sales process. As a labor team Jack, Dawson and Cameron were incredibly professional, efficient and thorough. Excellent communication and explanation of the process was maintained throughout the job's duration. -Dr. Michael Wofford

Dustin answered all our questions and provided repair options. Yiannis and Landon arrived on schedule and were very professional. They did a fantastic job lifting and leveling a sunken section of concrete driveway. It looks like new! After completing the repairs in only a couple of hours, they cleaned up everything. Great experience! I would definitely use them for any other similar repairs in the future.

Chris, Cody, and Pat were very professional, courteous, and they worked hard to get the job done. We would definitely recommend Mount Valley Foundation Services if you’re considering any crawl space or foundation work!

Chris was very professional and did a thorough job of explaining everything they needed to complete to make the crawl space up to standards. Jalen communicated when he was on the way and when he arrived. Explained everything, cleaned up afterwards, and provided me with pictures of the work that was done. I need an additional outlet for the condensation pump and once installed, he even offered to come back to complete that installation. He explained that how he set it up, the condensation run to the sub pump. I was impressed with the entire staff and their professionalism.

I contracted with Mount Valley Foundation to encapsulate my crawlspace. I worked with Trey to define the project work. He along Christian provided a competitive estimate and were available to answer my questions. The project included removal of all fiberglass insulation, fully encapsulating the space with top end vapor barriers, replacing the door, and installing a dehumidifier. The team worked for two days to complete all the work with the exception of wiring the dehumidifier which is being done by a third party. Cody led a team comprised of Cory, Zy, Billy and Lamont. They worked steadily and demonstrated they knew what they were doing. I was most impressed by their willingness to answer any questions. All of them were so polite. I would highly recommend Mountains Valley Foundation based in my experience.

Trey came out and gave an estimate. He was a very nice person and had a good demeanor. The cost of the project ended up being more than 40K, due to underlying issues with the house. WE won't be moving forward with the project, but I'd call them again if I needed an inspection.

Very happy with their service. Communication was excellent. Always informed of daily projects, and had all my questions answered.

We have been calling, and calling, and calling, and calling, and calling since we took on more and more water after Mount Valley Foundations Services "fixed" our hurricane ravaged basement. We have spent close to $30,000 with this company in the past two years and we cannot even get David Tillet and his team to respond to our phone calls, Think they guarantee their work? Think again.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
