Gary Christman Excavating LLC

Gary and Hallie Christman started Gary Christman Excavating, LLC in 1998. The primary purpose of the business was to do certified soil testing (perk tests) for septic systems in the State of Wisconsin. Gary then decided to pursuit getting his plumbing license so he could put in his own systems. After successfully completing Restricted Service Plumbing Apprenticeship in 2005, Gary has been designing, installing and repairing septic systems in Douglas, Washburn, Burnett counties in NW Wisconsin. We also do sewer thawing in the winter for frozen septic lines and septic tanks. We have added a roto rooter and camera with a locator so that we can offer a better repair service for the septic problems that arise. Also we carry sewer pumps and switches for older systems that may need upgrading. In 2011, we bought out Christman Brothers excavation. This includes 2 dump trucks, trailers, dozer, excavator and front end loader. We also have a screener to screen the black dirt. This gives us the opportunity to provide a full service excavation business.


My goal is to design and build the highest quality septic systems that are affordable to each customer. I take the extra time to know what my customer’s needs and expectations are. I enjoy the one on one contact with each customer.


I hold State of Wisconsin licenses in:

    • CERTIFIED SOIL TESTING (Soil testing for septic and storm water systems)

    • MASTER PLUMBER RESTRICTED SERVICE (Master plumber outside plumbing only)
