About Us

Willkomm Excavating & Grading, Inc., established by Nick Willkomm, is a family owned and operated business based out of Union Grove, Wisconsin since 1998. Nick Willkomm has grown the company with his beginnings in small, private work. From these beginnings, Nick has developed Willkomm Excavating & Grading, Inc., into a full-service union, excavating, grading, and site utility contractor business. We pride ourselves on leaving our clients completely satisfied with the work provided, as well as having all employees OSHA 10 certified to ensure the safety of all involved.

Willkomm Excavating and Grading inc. is continuously growing to fit our clientele as advancements and changes happen in the field of earthwork and site utilities. Under the new names of Nicholas and Nathan Willkomm, the sons of Nick Willkomm, they continue to follow the work ethic and morals instilled previously by their father while trying to expand into a bigger entity with a larger array of services available. Our satisfied clients include, but are not limited to, municipalities, WISDOT, general contractors, developers, as well as individuals (whether that be individuals in residential, commercial, or industrial markets). 

Willkomm Excavating & Grading, Inc. will continue to be the Southeastern Wisconsin staple in the construction industry for years to come.
