Jacob Frazier came to see the situation & explained in a way I could understand what the crew would do. He is very knowledgeable, friendly & answered any questions. He also walked me through the contract online via email & we are now just waiting for a date for the job to be done. I feel that if I have any questions or need anything else, I can call him for information or an explanation.

I'm so appreciative of the time and attention Ashton Gillen spent inspecting my home, answering my questions and helping me genuinely understand what was going on with it. His professionalism, warmth and transparency went such a long way in building trust and making me feel comfortable during a process that would have otherwise been much more stressful. Without hesitation I'd work with Ashton and Groundworks team again and I'm so grateful to have had their help so far. Extra humongous thank you, Ashton!

Trey Robinson has been absolutely awesome throughout the process so far. He was really through during the inspection process and really took the time to make sure his measurements were accurate to give us the best estimate. Then he took the time to actually explain each step of the way. This was super helpful! We are both very impressed with Trey and the OBA so far. We are still in the preparation stages, so I'll update this review once the work is finished.

I recently had the pleasure of working with Matt Koons from Basement Authority for an evaluation of my concrete driveway and walkway. From the moment he arrived, Matt was exceptionally polite, professional, and courteous. He conducted a comprehensive evaluation, thoroughly explaining the process and answering all my questions. What truly impressed me was his ability to create a custom quote on the spot, while fully honoring my specific wishes and concerns. Matt's expertise was evident, and I felt completely confident in his assessment. But what truly set him apart was his character. As he was leaving, he noticed a stranger struggling to break down and load some outdoor storage I had placed at the curb. Without hesitation, Matt jumped in to help, demonstrating genuine kindness and a willingness to go above and beyond. Matt Koons and Basement Authority have earned my highest recommendation. Their professionalism, expertise, and commitment to customer satisfaction are truly outstanding. If you need concrete lifting or any basement services, don't hesitate to call them. 5 stars!

Marvin and Larry arrived Saturday, April 11, 2026, and began working right away to install a powerful dehumidifier that vented moisture from the basement to the outside. The process was explained to me and to my contractor; they made sure both of us understood the whole process of beginning to remove mold from my basement. Both young men were respectful and worked quickly and efficiently. Before they left they made sure we understood what they had done that day, and left a manual for the dehumidifier, which my contractor appreciated. Both were open to any questions that we had.

Our crew that came out to work needs a raise. It’s almost winter and they sent this crew to come work in literally any degree weather that came their way. They got the job done and met the deadline in this freezing cold weather. I can’t believe they actually worked in these temps. I am impressed.

David and crew did an outstanding job! They leveled and stabilized our house in strategic areas with piers and jacks and it closed up some cracks in the drywall. They communicated well and were very professional. They also cleaned up everything well. I highly recommend these guys that came down to Durango from Grand Junction. I also want that TJ Stastny was amazing too with guiding us as to recommendations and the free consultation up front here in Durango. He was top notch. We were hoping to find a company that could do this and so happy with the result! They use lazers for determining level and are highly detail oriented. Also they will follow up to check up on things for 3 years with the plan we chose. The company was also helpful with finding financing. Thanks so much!

We had a that was cracked and shifting. Groundworks came and installed braces to stabilize the wall. The crew that show up were Josh W., Chris S. and Robert P. They were amazing. The work was done in one day. I wish every crew I’ve had was a great as these guys. If you have foundation problems or basement issues, I highly recommend Groundworks.

Time will tell for longevity, but we're happy. Engineer, Sean Wang, communicated everything quite clear and we understood what was going on. We needed more posts an the center beam of our house jacked up due to sagging. The three workers who came out, Mike Baines, Bryan Covell, and Brandon Pritt were all great. Very respectful of our property, really tried to keep everything neat and tidy. Answered all our questions along the way. Good job cleaning up. I love that they brought their own buckets (step up from other companies.) Again, all three installers of our new support posts were great and very polite. They did a great job from what we can tell.

Case Studies
“We had our crawlspace encapsulated. Katie, our inspector, was very professional and spent a lot of time with us explaining the encapsulation process. She also responded immediately to our phone calls after we signed up! Jesse, Micah and Nick were our installers. They were great, worked hard, organized and polite. They explained everything we wanted to know during the process. They were neat (cleaned up everything). They were a great team. Thanks guys. So far, so good!”
