Ryan and his crew were amazing--We had a major and complicated sewer pipe replacement and they were timely, did great work, and were super easy to work with. I know we got a great deal, given the size and extent of the project. I'd highly recommend them to anyone. We were joking the other day when we walked by a big hole in the ground near someone's house, "They should have hired Superior Underground!" It's true though.

Got references and called MANY plumbers ! Don't waste your time and money with anyone else; these guys are the best and cheapest we found. Very easy to deal with; honest and straightforward.

Called a bunch of big name people and they either never called back or quoted an insane amount. Ryan and Sup. Underground not only showed up on time but left our yard looking better then before our sewer was replaced. Best experience I have had with any contractor in a long time. Great work and even better price.

This company epitomized the good experience one would want when hiring an outside contractor. This guy was outstanding and his office person was equally good. In my opinion, you won't go wrong with company. Hire them and don't be afraid.

From the very first contact with Ryan and JJ they kept us informed with timeline of when the job would be done. They showed up on time on install day. They worked efficiently with each other to get the job done. And they didn't mind us watching throughout the process. They cleaned up the area very nicely after they completed the install. I would highly recommend this company for your excavation needs.
