I could not be more happy with the work that St. Louis Excavation did for me when they repaired my Sewer Lateral line in my four family building in the city. The work was done quickly, competently, and was reasonably priced.

I am a local Realtor. Several of my clients have used STL Excavation for their sewer repairs. Mike and his crew know what they are doing, and they do it well. He always comes out right away to bid the job, it is completed in a timely and professional manner, and his prices have always been far below what other contractors charge. I recently needed a large sewer repair at one of my own properties. Mike was the only call I needed to make, and I’m glad I did. I will continue to use and recommend STL Excavation in the future!
