"Kiefer was great to work with. He was very thorough, took care not to damage our lawn while digging, and did a great job."

"When I went to redo my driveway in Belgrade, I gave Kiefer over at ADM Dirtworks a call, and he did a phenomenal job. As you can see in the attached before and after photos, he installed a new culvert and expanded my driveway to allow me to park two rows of vehicles in my driveway. When he was finished, I had a beautifully finished driveway that was graded to shed water so I no longer had puddles when it rained. Additionally, he built me a leveled pad to set my shed on. If you’re looking for a professional to take care of your dirt work needs, Kiefer is the man for the job!"

"Great the way the site was finished 100% Kiefer took the time to listen to concerns and takes pride in what he does. I don’t have anything to compare his price to because none of the other contractors followed through with estimates! I was relieved to have this completed."

"ADM regraded my driveway and it looks great. They were very easy to work with. They cleared my weeds, regraded the driveway, leveling it out to remove a low spot and ensure that the water flows to the sides of my driveway and not settling in puddles in the middle of my driveway. I will use them for all grading needs in the future and I highly recommend them for your grading needs."

"I had an outstanding experience working with Kiefer Wilkins, owner of ADM Dirtworks. I hired Kiefer to manage a fairly extensive driveway and yard renovation, and the results exceeded my expectations. From the very beginning, communication was excellent. Kiefer was responsive, clear about the scope of work, and always willing to talk through ideas or adjustments. What really stood out was his attention to detail and the pride he takes in doing the job right. Every step of the project was handled professionally, and the finished product shows it. He also worked closely with me to find cost-effective solutions without cutting corners, which I really appreciated. It’s rare to find a contractor who balances quality, transparency, and budget the way Kiefer does. If you’re looking for someone reliable who delivers high-quality work and actually cares about the outcome of your project, I highly recommend Kiefer and ADM Dirtworks. I wouldn’t hesitate to hire him again."

"We have worked with kiefer on a few projects now and has been great to work with. ADM is great with their communication and very professional. You can expect to always get a hold of them followed by quality work. Highly recommend!"

"Great work and done fast. Highly recommend"

"I've known Kiefer for several years. He is honest, trustworthy, and hard working. I absolutely recommend ADM Dirt Works as a trusted contractor. His work quality is top-notch."

"Helped dig a trench for my solar project, even went out of his way and pulled out a shrub when asked. Did a great job, even hand dug in a blizzard. Definitely would recommend! Thank you"

"Awesome company, very professional and great work. Kiefer is awesome to work with and gets the job done in a timely manner. Definitely recommend!"

"Great contractor to work with and Hire to get any dirt related work done!"

"We used ADM to do prep work for an extension of a concrete patio in my backyard. You can see how small it was in the photos I added. Anyways, my backyard is pretty steep, but they did a great job with the prep work to make sure the new concrete matched the existing, and then made a new gradual slope after the concrete was poured. (Also, they did a great job of protecting my existing grass, which I feel like a lot of contractors don’t pay attention to. I really appreciated that). They were on time, efficient, and really organized. I wanted to wait to write this review to see how everything held up, and it still looks great! I added some after photos right after we put new sod down. Highly recommend, the dog even loves it!"

"Kiefer is awesome! Stand up guy, knows his stuff and runs nice new equipment with very little down time. He confidently took on my driveway rebuild and concrete slab & wall prep, delivered exactly what I wanted and made sure everything was up to snuff before final invoicing. Even took time on the weekend to help put in my fence after the project. I can’t recommend him enough."

"Keifer at ADM dirtworks was great to work with. We needed some very large, dead junipers removed. He quoted and completed the job within a couple of days which is unheard of in the Gallatin Valley anymore. His pricing was fair and he did a great job. We would definitely highly recommend him."

"Kiefer does a wonderful job plowing snow away from your driveway. I would and will recommend him highly."

"I'm so happy with the service, attention to detail, and price that ADM Dirt works has done for me this year at my storage unit facility. I highly recommend this company!"

"Absolutely incredible service. Called to get a quote and in less than 24 hours my extensive driveway was plowed beautifully. Would 100% recommend. Will be using all winter for snow removal services."

"Kiefer completed the dirt work on our new building and it turned out great! There were some challenges along the way, like random buried metal and other junk, but he removed all of those items and got us ready for concrete. Thanks"

"Kiefer was great to work with! He came out and looked at our project and got us a quote in a timely fashion. Once on site, he did a great job and even took the time to tackle some additional work that was not originally discussed."

"We have worked with ADM on multiple excavation and pavement projects - driveways, patios, and parking lots. They’re also experts at TrueGrid permeable paver installations. Reliable, quality work, and efficient!"

"Keifer is an absolute pleasure to work with. He was able to help me solve for multiple landscaping projects - rock rocking, house skirting along with installing a True Grid patio which helped save me money vs. pouring another concrete pad. I would highly recommend ADM dirt work for your outdoor projects."

"Kiefer was extremely polite and professional. Any projects requiring excavation I have, he will be the first person I call."

"I've had several projects completed by ADM dirt works and every time I've been very happy with the results. Kiefer is great to work with. Always respectful, on-time, listens to any concerns and strives to come up with solutions. His prices are competitive, but what makes me continue choosing ADM dirt works over others is Kiefer himself. When you find someone reliable, honest and hard-working, you keep them!"

"Kiefer is a prompt and professional guy. He does quality work and honors his word."
