Our History

Peerless Service Company was started by Jim Sass and Terry Nauman as a two-man crew after they left a rival company to go out on their own. Their first building was in downtown Dubuque.

Peerless Service Company hired their first employee

Peerless Service Company moved from their downtown location and built their current location at 17656 S John Deere Rd on the edge of town

Peerless Service Company was purchased by Municipal Well and Pump (Waupun, WI) but continues to run as a separate subsidiary with expanded offerings including more expansive well rehabilitation, well drilling and televising. Their company name changed slightly to Peerless Well and Pump.

Project Manager Patrick Harrington, an employee of Municipal Well and Pump for six years, transitions to Peerless, taking his years of customer service to a new region of clients.
