Our Story

Boumeester & Sons Excavating, founded in 1983 by Bill Boumeester, is built on hard work, honest prices, and a handshake that truly means something. Bill earned a strong reputation across St. Croix County as the go-to expert for getting the job done right.

Today, his sons, Jim and Larry, proudly uphold that legacy, ensuring that the high standards set by their father remain unchanged: they show up when promised, treat your property as if it were their own, and stand behind their work. The name on the truck continues to signify reliability and quality just as it did in 1983.

Whether you need septic system installation, a foundation dig, or help with a drainage issue that’s been bothering you, you will speak directly with Jim and Larry — not a call center or salesman. This is how a family business should operate.

Jim is licensed to install and service private onsite wastewater treatment systems (POWTS) and holds a Wisconsin Master Plumber Restricted Service License #222904.
