Wisconsin requires well drillers and pump installers to hold a state license to construct, modify, or service private water wells. Hiring a licensed contractor protects your groundwater, keeps you compliant for property sales and loans, and ensures work meets state construction standards. Always verify a contractor's current license status with the state before hiring.
