Delaware licenses two kinds of well business: Water Well Contractors (98 approved on 10-07) and Pump Installer Contractors (14), every license expiring December 31, 2026. A business that contracts for well pump work must hold one of the two (7 DE Admin. Code 7302), so both are shown for pump work; water well contractors are also shown for drilling and sealing. Firms whose name says environmental, engineering or geotechnical work are counted, not shown, and a listing needs a Google profile in a well, pump, plumbing or water treatment trade (Delaware also licenses builders, excavators and irrigation firms that drill).
