We are so happy with the work Kevin did for us. We gave him a few ideas of what we were looking for, he ran with it and far exceeded our expectations. His pricing was extremely reasonable. He was very professional, kept us up to date with start timing and throughout the project. He also completed the work much faster than expected. I highly recommend Theiss Excavation!!

Kevin did an incredible job. Our backyard had a significant dip that was causing water and mud conditions during a summer with little rain. He worked quickly, efficiently and offered a good price. I would work with Theiss Excavation again for other projects at our house.

I called Kevin to help level a pad for a new shed at my home. I needed a professional to fix my mistakes and he definitely delivered. He showed up exactly when he said he would, and went above and beyond the scope of work. Incredibly thrilled with the outcome and would absolutely recommend reaching out to him for any site prep or excavation services. Can't recommend him enough!

Kevin recently completed a project at my home, and I couldnt be happier with the results. He is an excellent communicator, took the time to explain the work, and worked with my ideas while bringing his own vision and expertise to the project.His attention to detail is exceptional, and its obvious he takes great pride in his work. The quality of the finished product exceeded my expectations, and he left the worksite spotless when the job was done.After speaking with several excavation companies, Theiss Excavation stood out for its professionalism, quality, and reasonable pricing. Kevin is honest, hardworking, and truly loves what he doesand it shows.I highly recommend Theiss Excavation to anyone looking for top-quality excavation work. I am extremely happy with the results!
